In the automotive industry, active safety refers to the Advanced Driving Assistance Systems (ADAS) in a vehicle that help drivers reduce the severity of accidents or avoid them entirely by managing steering, braking and propulsion. Safety has always been of paramount concern in the automotive world.

1. The industry has developed world-class testing protocols related to vehicle safety, and its advances have been highly successful at reducing the number of traffic fatalities.
2. The rate of fatalities per 100 million vehicle miles traveled has decreased dramatically over the last few decades, from 3.35 in 1975 to 1.13 in 2018.

The majority of those gains have come from “passive safety” features – that is, features that only activate when an accident occurs and lessen any injury to the driver and passengers. These include seat belts and airbags, as well as structural improvements such as crumple zones that absorb the energy of a crash.

However, the gains from passive safety have started to plateau. Additionally, distracted driving has emerged as an increasing issue, partially as a result of smartphones. To continue the trend in improving safety and reach the industry’s goal of zero vehicle-related accidents and fatalities, vehicles have to help drivers stop hitting things.

That is where active safety comes in. By using sensors such as radar, cameras and ultrasonic sensors, a vehicle can perceive the world around it. Processors then interpret that information, acting as a second set of eyes for the driver and taking actions if needed.

Active safety demonstrates clear benefits Relatively simple warning systems such as blind spot detection or forward collision warning have the potential to save lives on their own, but when coupled with a technology that takes action beyond a simple warning to create an active safety system, the results are impressive.

For example, a vehicle could detect if it is approaching an object too quickly, attempt to warn the driver and then apply the brakes automatically if the driver doesn’t respond in time. According to the Insurance Institute for Highway Safety, forward collision warning with automatic emergency braking reduces rear-end collisions by 50%,

This technology has become much more common in recent years as rating agencies such as Euro NCAP put active safety technologies on their testing roadmaps, In the United States, 20 automakers, representing 99% of U.S. light vehicle sales, committed to making the technology standard by 2022, Given that the National Highway Transportation Administration estimates that 94% of all accidents are caused by human error, there are many other opportunities for improvement.

Examples of more advanced active safety systems include features such as automatic lane change, highway assist and traffic jam assist. In these examples, multiple sensors around the vehicle must be integrated through sensor fusion, so that powerful domain controllers running advanced software algorithms can process the information and make driving decisions.

• While entry-level active safety systems may take a single action, such as braking, these more advanced systems assist the driver with multiple aspects of controlling the vehicle.
• For example, they typically will manage steering – to keep the vehicle in a lane or navigate around slower vehicles – while simultaneously managing the vehicle speed to maintain a safe distance from other vehicles and obstacles.

What is active safety in vehicle?

Automotive sector – In the automotive sector the term active safety (or primary safety) refers to safety systems that are active prior to an accident. This has traditionally referred to non-complex systems such as good visibility from the vehicle and low interior noise levels.

Nowadays, however, this area contains highly advanced systems such as anti-lock braking system, electronic stability control and collision warning/avoidance through automatic braking. This compares with passive safety (or secondary safety), which are active during an accident. To this category belong seat belts, deformation zones and air-bags, etc.

Advancement in passive safety systems has progressed very far over the years, and the automotive industry has shifted its attention to active safety where there are still a lot of new unexplored areas. Research today focuses primarily on collision avoidance (with other vehicles, pedestrians and wild animals) and vehicle platooning,

What is an active feature on a car?

Active Safety Features in Cars – As the name suggests, these systems are always in a vehicle to mitigate any accidents and mishaps. These systems use- Ultrasonic, Radar, Lidar and camera s to monitor the surrounding. Various active safety systems are listed below.

Adaptive Cruise Control (ACC) ACC is the higher version or next stage of cruise control where in the vehicle adjusts its speed depending upon the speed of the vehicle in front. Type of sensor- Radar, Ultrasonic and Lidar Lane Departure Warning (LDW) On motorways it is necessary to stick on to a single lane making way for faster traffic.

However, prolonged driving which leads to stress and lack of concentration, may result in drivers not following this. A lane departure warning system uses any of the following sensors to clearly identify the path and takes necessary preventive measures, adhering to lane change discipline and practise.

1. Type of sensor- Radar, Ultrasonic and Lidar Night Vision Even with innovations in automotive lighting it is still difficult for users to have a clear view of the road ahead.
2. With assistance from a night vision camera or lidar, users will be assisted with object avoidance in their path in the dark.
3. Type of sensor- Radar, Ultrasonic and Lidar Blind Spot Detection (BSD) Blind spots are areas surrounding the vehicle that are not captured by rear-view mirrors and side view mirrors.

There is no ideal position of the mirror or driver seat that can eliminate this blind spot. A lot of accidents can be attributed to changing lanes when other vehicles are in blind spot. As a result, an automatic warning sign/ indicator to alert the driver about any object or other vehicle in the blind spot becomes a major requirement to enhance safety.

• Type of sensor- Radar, Ultrasonic, Camera and Lidar Driver Monitoring Solutions- Driver Monitoring solutions or systems in general use a single camera to track various facial features of the driver.
• Upon tracking facial features, CNN models or traditional machine vision algorithms are used to predict any distraction or sleep deprivation.

A sophisticated DMS can do more than just distraction alerts, like cabin personalization to specific user and emotion estimations. Road Sign or Vulnerable Road User Detection- As vehicles become semi-autonomous, they should be able to identify various traffic signs, traffic lights and other objects and pedestrians on the road.

What is the difference between active and passive safety features?

Passive versus active safety measures – So what is the difference between active and passive safety features in cars? The answer is simple. Active safety features prevent accidents from happening. Passive safety features lessen the chance of death and serious injury in instances where an accident is unavoidable.

Is power steering an active safety feature?

How active safety systems work – An active safety system is a term used to describe features of a car such as ABS, Traction Control and Power Assisted Steering, These features are designed to improve safety while you are driving the vehicle. They are used to maintain the stability of the vehicle while undertaking regular driving tasks such as braking, accelerating and steering.

What are examples of passive and active safety systems in a vehicle?

What is Active Safety System in the car? – Active Safety includes set of safety features which reduce the chances of an accident or collision in the first place. Some manufacturers also call it as the ‘Primary Safety System’. Manufacturers employ the active safety systems mainly to avoid the accident.

• These systems activate before the accident takes place so that they could possibly avoid the accident.
• The engineers/vehicle designers build a car with a high level of active safety through superior design.
• This includes characteristics such as road holding, visibility, comfort, handling, and ergonomics.

Therefore, the safety system such as the Anti-lock Braking System or ABS belongs to the active safety. However, the airbags, seatbelts, and others safety features come into play during an accident. Hence, they are called the passive safety systems. Active systems respond to an abnormal event such as a safety problem.

These systems can be activated manually by the driver or automatically by a computer-driven system (by an ECU ). Or sometimes, they are part of the mechanical design itself. Furthermore, such technologies could help avoid collisions and mitigation. Hence, they will play a key role in automobiles in future.

Vehicle component manufacturers such as Bosch, Delphi and ZF are some of the leading companies which supply such safety systems. Here are some examples of active safety in a car–

Positioning of driver’s seat to allow better visibility Low noise level in interior Chassis balance and handling Reduced unsprung weight Better tyre grip Legible instrumentation and warning symbols Head up displays Collision warning/avoidance Anti-lock braking system Brake Assist Early warning of severe braking ahead Electronic Stability Control (ESP) Traction control Chassis assist Adaptive or autonomous cruise control system Intelligent speed adaptation

What is the #1 most effective active safety device in your car?

Pedestrian detection – This system uses the features of forward collision warning and automatic emergency braking to help protect pedestrians. The vehicle’s camera(s) or radar are looking for a pedestrian in the vehicle’s path. Some systems will alert the driver with an audible or visual alert and some will even start automatic emergency braking if a collision is deemed high.

What is the difference between ACC and AEB?

ADAS Braking Technology Official websites use,gov A,gov website belongs to an official government organization in the United States. Secure,gov websites use HTTPS A lock ( A locked padlock ) or https:// means you’ve safely connected to the,gov website.

• Share sensitive information only on official, secure websites.
• This category includes automatic emergency braking (AEB), and adaptive cruise control (ACC) systems.
• AEB systems detect when a truck is in danger of striking the vehicle in front of it and braking automatically if needed.
• ACC helps with acceleration and/or braking to maintain a prescribed distance between it and the vehicle in front.

Some systems can come to a stop and continue. While not required for ADAS, air disc brakes (ADBs) are foundation brake systems that use calipers to squeeze pairs of pads against a disc or rotor (instead of using shoes to apply pressure against a drum in traditional drum brakes) to create friction needed to stop the vehicle.

What is active safety brake?

Autonomous emergency braking (AEB) AEB systems start braking automatically if a collision is imminent and the driver is not taking any action (or not fast enough). AEB can detect a potential collision and activate the brakes to avoid it, or at least mitigate its impact.

Are airbags passive or active safety?

What are Tesla Active Safety Features?

Active safety features vs. Passive safety features – The only real difference between active and passive safety features is what they are intended to do. Active safety features are designed to prevent collisions and accidents from happening. Examples of such features available on Mazda vehicles include blind spot monitoring, radar cruise control, smart brake support, and pedestrian detection.

All of these features, among others, are put in place to help drivers avoid accidents. Passive safety features, on the other hand, are meant to limit the damage of a collision that does occur. Some accidents are simply unavoidable. When they happen, it’s good to know that you have some protection. Passive safety features are things like airbags, seatbelts, and crumple zones.

If you do get into an automobile accident, passive safety features are precautions put in place to keep you as secure as possible. You might also like: Those interested in learning more about safety technologies are encouraged to come to Tuttle-Click Mazda.

What is the difference between active and passive sensors in vehicles?

An active sensor is a sensing device that requires an external source of power to operate; active sensors contrast with passive sensors, which simply detect and respond to some type of input from the physical environment. In the context of remote sensing, an active sensor is a device with a transmitter that sends out a signal, light wavelength or electrons to be bounced off a target, with data gathered by the sensor upon their reflection.

Active and passive sensing technologies are both used in remote sensing to make observations and measurements from a distance or on a scale beyond those observable to the naked eye. Sensors can also be used in harsh environments and places that are inaccessible to people. Active sensors are also widely used in manufacturing and networking environments for example to monitor industrial machines or data center infrastructure so anomalies can be detected and components can be repaired or replaced before they break and shut everything down.

Examples of other active sensor-based technologies include: scanning electron microscopes, LiDAR, radar, GPS, x-ray, sonar, infrared and seismic. However, as can be the case with some sensors, seismic and infrared light sensors exist in both active and passive forms.

1. Depending on what is being sensed, these various sensors might be mounted to a satellite, an airplane, a boat or a submarine UAV drone.
2. They might also be mounted to another convenient observation point, such as a building top.
3. The data gathered by remote sensing is used for everything from cartography to resource exploration to atmospheric and chemical measurements.

Remote sensing is also essential to the Internet of Things ( IoT ), in which almost any physical or logical entity can be equipped with a unique identifier and the ability to transfer data over a network autonomously. This was last updated in September 2014

Is Active Steering the same as power steering?

BMW Power Steering System, Rack, Hoses, and Lines – Aside from a few exceptions, BMW uses power-assisted rack-and-pinion steering on every model. In concept, modern BMWs are no different than the power steering systems from 40 years ago – turning the steering wheel rotates a shaft, which slides a toothed rack with assistance from a hydraulic pump or electric motor, pushing and pulling on the tie rods at each wheel to point the tires in the direction you want to go.

1. Several major advancements have been made since the original 1970s power rack-and-pinion systems and BMW is now all-electric.
2. But millions of hydraulic power steering systems are still on the road today and they need to be maintained.
3. Steering racks are expensive and replacement can be very invasive.
4. Preventative maintenance such as fresh fluid and replacing leaking hoses will help prolong the life of the rack.

However, looking at the power steering system on your car can be intimidating with many hoses crisscrossing the engine bay. We’ll explain the layout and function below. All hydraulic systems will have 4-5 hoses/pipes that carry hydraulic fluid from the reservoir, to the pump, to the rack, and then back to the reservoir.

• On later cars one of these hoses is actually a metal cooler that sits in the airflow and cools the fluid after it leaves the rack.
• Factory BMW hoses are reinforced rubber with metal fittings except where the hoses attach to the reservoir with hose clamps.
• Below is a diagram showing a typical hose layout.

This is for an E46 M3 but nearly all BMWs using a belt-driven PS pump will have a similar hose layout. PS hose layout shown for E46 M3. This is typical for all BMW hydraulic power steering system hoses. A = Fluid Reservoir | B = Inlet Hose (“Intake Manifold”) | C = Power Steering Pump | D = Pressure Hose E = Steering Rack | F = Return Pipe | G = Fluid Cooling Pipes (“Cooling Coil”) | H = Return Hose (“Radiator Return Line”) A.

• Power Steering Reservoir, aka “Oil Carrier”.
• This sits at the top of your engine bay, usually on the driver’s side.
• You can top off or refill your fluid in this container (make sure you use the correct fluid – see below!).
• Also inside is a filter that will trap metal and other foreign particles so they do not reenter the system and cause damage to the pump or rack.

The filter is not serviceable so it’s a great idea to replace the reservoir at some point.B. Supply Hose, aka “Intake Manifold” or “Suction Pipe”. A rubber hose running from the reservoir that supplies the power steering pump with fluid. Crimped hose clamps attach it at both ends.

These clamps are crimped into place and cannot be re-used so we recommend getting the appropriate premium traditional clamps if you’re ordering new hoses. As with any other rubber hose, this one will leak at some point from either dry rotting or swelling from over-saturation.C. Power Steering Pump, aka “Vane Pump”.

The internals of a PS pump are quite simple but the bearings can become dry, requiring the complete replacement of the pump itself. The PS pump is usually driven from the same serpentine belt as the alternator and water pump.D. Pressure Hose, aka “Expansion Hose”.

This runs from the pump to the rack. At either end is a hard metal line secured with a bolt and copper crush washer. The hose has extra length so the system can have more fluid capacity. Unfortunately it has a lot fittings where rubber hose meets metal line. These fittings are compression crimp-style swage (“swedge”) fittings that are very common in the automotive world.

These swage fittings are the most common area for PS leaks on your BMW. It’s easier to replace the entire line with a new OEM or BMW part than to try and repair the line.E. Steering Rack, aka “Hydro Steering Box”. Most BMWs use rack-and-pinion steering.

1. The pinion is the steering shaft and it meets the steering rack at an angle.
2. Turning the steering wheel turns the pinion shaft and the pinion teeth mesh with the rack teeth to move the rack side-to-side.
3. In this way, power and manual steering racks function the same.
4. The power assist comes from the hydraulic fluid pushing on a piston which moves the rack.

Manual steering is not recommended unless you have a vintage 2002 or E21 with skinny tires.F. Outlet Pipe, aka “Return Pipe”. This hose runs the fluid out of the rack and into the steering cooler. On older models there is no cooler and this hose runs back to the reservoir.

Like the Pressure Hose it has a metal pipe with swaged fittings that are prone to leaking.G. Power Steering Cooler, aka “Cooling Coil” or “Steering Loop”. This is a hard metal line that bends back on itself, doubling the surface area. This pipe is usually placed at the front or bottom of the rack so it’s in a little bit of airflow.

The metal pipe exposed to air has a cooling effect to the fluid inside. Leaks are not very common here but rust and corrosion are. And it’s position in the airflow also exposes it to rocks and debris where it can be damaged. Older BMW models like the E30 325i did not have a cooler.H.

1. Return Hose, aka “Radiator Return Line”.
2. BMW has two hoses they call a Return Line.
3. We’re going to clarify things and call whichever hose attaches to the reservoir is the Return.
4. F” in the diagram we are re-naming the Outlet Hose.
5. In this diagram, the Return comes from the cooler and returns the fluid to the reservoir.

Like the Inlet Hose (B) it has non-reusable clamping hose clamps where the hose meets the reservoir. Leaks are very common here. BMW Power Steering Fluid Your BMW power steering is filled with either ATF or hydraulic oil (CHF) and it is vital that you use the correct fluid as the two cannot be mixed.

1. The cap on your fluid reservoir will indicate which fluid to use*.
2. ATF has been the traditional power steering fluid for decades and you can use any off-the-shelf brand or type (Dexron III seems to be very common at auto parts stores for a cheap top-off).
3. But if you have a green label on the reservoir cap you must use CHF.

The two fluids are not miscible and will not mix. * BMW used the same reservoir cap for either but added a green sticker for CHF cars. They really should have issued a new cap because under the sticker the cap might say ATF! If the CHF label comes unglued and falls off, you could be left with a misleading cap! You can confirm the fluid by checking the color of the fluid – red is ATF, green is CHF.

CHF stands for Central Hydraulic Fluid and it means your vehicle was engineered to draw hydraulic fluid from a single source. The fluid for the power steering system is shared with another system – such as self-leveling suspensions, Dynamic Drive, power convertible tops, or just about any other system that is hydraulically driven.

It doesn’t matter if your car doesn’t have these other systems, BMW supplied your car from the assembly line with CHF and you must continue using it. Using ATF in a CHF system can deteriorate seals in the hydraulic system, leading to leaks or poor performance from that system.

1. Since some cars rely on the CHF for braking assist you should only be using the correct fluid.
2. There could be other factors as well, such as viscosity differences at various temps.
3. BMW Power Steering Leaks Is the bottom of your engine bay an oily mess? It’s not uncommon to see a coating of oil throughout your engine bay and BMW oil leaks can usually be traced to a few problem areas: valve cover, oil filter housing, oil pan, and power steering hoses.

Engine oil is always a dark brown or black color. But power steering fluid is red (for ATF) or green (for hydraulic fluid) which makes identifying leaks easier. Power steering leaks usually come from two sources: the hose connections to the fluid reservoir or the crimped metal fittings used where rubber hose meets metal pipe.

1. The connection to the fluid reservoir is by a crimped hose clamp often referred to as an Oetiker clamp.
2. These are one-time use clamps installed with special crimping pliers.
3. Over time the crimp portion weakens and the clamp is allowed to expand, creating a leak.
4. Since there is no adjustment you can’t tighten the clamp to stop the leak.

However, you may be able to remove the Oetiker clamp very carefully and install a traditional clamp in its place. As long as the hose itself isn’t damaged or swollen you can tighten the clamp and stop the leak. Power steering hose assemblies are rubber hoses combined with metal pipes.

• Most of the Pressure or Outlet hoses are built this way so the hose can attach to the steering rack or pump.
• If your leaks are not coming from the mounting bolts and crush washers (easy fix) it’s likely coming from the crimped connection between rubber and metal.
• This is not an easy fix and a full replacement is typically the best course of action.

Though they can be expensive, depending on how complex the hose is, a replacement should give you many years and tens of thousands of miles of leak-free service. BMW Steering Options, Systems, and Technology Think turning the steering wheel turns the front wheels? You’re wrong.

There is so much more going on between the steering wheel and the road wheel that almost no one knows about let alone understands. The last time BMW offered manual steering was on the E21! And since then the systems and technology have made several leaps. The other side of the coin is that steering racks have not changed all that much – they are still using hydraulic fluid and grease even if the source of steering assist has migrated from a hydraulic pump to electric motors.

Servotronic An increase in steering effort by way of reducing power steering assistance. As vehicle speed increases the amount of pressure from the pump is reduced, thereby increasing steering effort (heavier steering). The faster you go the heavier the steering gets.

1. This feature was released on multiple models on a limited basis in the late 1990s.
2. The first versions used a mechanical bleed valve on the power steering pump while later electric systems simply reduced motor output.
3. Some form of Servotronic exists on every BMW since electric systems were introduced.
4. Electric Power Steering (EPS) Electric steering assist comes from an electric motor mounted on the steering rack or column instead of a remote pump and fluid reservoir.

The benefits of this system make it attractive: fewer (or no) hydraulic lines in the engine bay, leading to fewer oil leaks. less maintenance, and removing the parasitic drag that the hydraulic pump has on the engine (improving fuel economy and power efficiency).

1. It’s also easy for BMW to fine-tune and change the steering characteristics, i.e.
2. Heavier steering for sporty models.
3. It’s also a necessity for such technology as self-parking and automated driving.
4. Electric power steering was first introduced on the E85 Z4 models in 2004 and continues with every subsequent new model thereafter.

Active Steering Active Steering is a form of electric power steering but with a different gear set within the EPS module. Active Steering will alter the angle of the road wheels in relation to the steering wheel input and vehicle speed. More steering angle at low speeds such as parking but reduced angle when at speed.

You won’t have to spin the wheel through 3-4 turns to parallel park but the steering will not be darty and nervous when driving fast. Active Steering was first introduced on the E60 5-series in 2004 but remained an option on all models. An updated Integral Active Steering feature was offered on the F10 5-series for 2011.

The E60 system combined electric and hydraulic assistance to form a very complex system. The Integral system on the F10 became all-electric and included a rear-wheel steering feature. Rear Wheel Steering was implemented with the F01 7-series and consists of an actuator and control unit on the rear suspension.

The actuator will push/pull on the rear upper track rods in the suspension, changing the toe on the rear wheels. Total travel was 8mm which equated to a maximum toe change of 3°. BMW’s name for it is Rear Axle Slip Angle Control (HSR) and was only installed on cars with front Integral Active Steering and Dynamic Handling Package.

Variable Sport Steering Variable Sport Steering combines a variable steering rack with an electric motor for the first time. In the past it was possible to vary steering response by changing the teeth on the steering rack – finer teeth meant a quicker ratio that could change to coarser teeth to slow steering response.

Variable Sport Steering was first introduced on the F25 X3 models in 2011. Dynamic Drive and Active Roll Control Dynamic Drive or Active Roll Stabilization (ARS) is a set of variable sway bars on the front and rear axles. Instead of a fixed sway bar of consistent diameter, the Dynamic Drive uses a variable sway bar.

Bigger bars act like a large lever in the suspension, forcing wheels back to the pavement during extreme cornering. Unfortunately this tends to limit suspension travel and make the ride stiffer, especially over single wheel bumps. Dynamic Drive is able to allow single wheels to move over bumps without engaging the sway bar, keeping the ride more comfortable until the system is activated during hard cornering.

1. This doesn’t have a lot to do with steering systems except the Dynamic Drive components and steering systems often occupy the same space inside the engine bay and BMW has different parts for the various layouts.
2. If you’re looking at your front sway bar and it seems to have a large electric motor in the middle, instead of a consistent diameter across, that is the Dynamic Drive actuator.

What are examples of passive sensors in cars?

Front Impact – Passive Safety sensors for frontal collisions are accelerometers that determine through the measurement of deceleration forces whether there has been a serious enough rapid change in the vehicles movement to warrant the deployment of passive safety devices such as seat pretensioners and airbags.

The accelerometers are connected to computer chips and software programs that evaluate the accelerometer input data and then determine if a deployment of the safety devices is needed. This process of measuring data and calculating a decision to deploy varies by vehicle, but generally must be done in under 20 mili-seconds.

This is one of the most difficult processes to be done in the time frame. Passive Safety Electronic Control unit and accelerometers
