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.

• 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.
• 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%,

1. 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,
2. In the United States, 20 automakers, representing 99% of U.S.
3. Light vehicle sales, committed to making the technology standard by 2022,
4. 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 an example of an active safety system?

Active and passive automotive safety systems Passenger safety occupies a prime spot in the automobile sector today. Stakeholders across the automobile value chain acknowledge the importance of passenger/occupant safety and are constantly upgrading their offerings to provide fail safe safety technologies that will protect passengers and pedestrians.

Proactive policy implementation and consumer awareness has played a key role in making automotive safety systems popular. Author: Atul Kumar, Team Lead (Automotive & Transportation Domain), MarketsAndMarkets However the penetration of these lifesaving technologies differs from country to country. Economically developed countries tend to have a high penetration of these technologies across various passenger and commercial vehicle segments.

Traditionally Automobile Safety Systems can be classified in to two segments, namely Active Safety Systems and Passive Safety Systems. Active Safety Systems as the term suggests play a preventive role in mitigating crashes and accidents by providing advance warning or by providing the driver with additional assistance in steering/controlling the vehicle. Head-Up Display (HUD), Anti-Lock Braking Systems (ABS), Electronic Stability Control (ESC), Tire Pressure Monitoring System (TPMS), Lane Departure Warning System (LDWS), Adaptive Cruise Control (ACC), Driver Monitoring System (DMS), Blind Spot Detection (BSD) and Night Vision System (NVS) are common Active Safety Systems.

• Passive Safety Systems play a role in limiting/containing the damage/injuries caused to driver, passengers and pedestrians in the event of a crash/accident.
• Airbags, Seatbelts, Whiplash Protection System etc.
• Are common Passive Safety Systems deployed in vehicles these days.
• An emerging trend witnessed in the global automotive safety system market is the increasing demand from the countries like India, China, Russia and Brazil.

Since the market for the safety systems like Airbags and ABS in developed economies is maturing and becoming saturated, OEMs and suppliers are focusing on increase demand from emerging markets. The demand is becoming higher in emerging markets primarily because of the improving road safety standards/supporting legislation and consumer awareness.

Active safety systems: Passive safety system:

Head up display: The automotive HUD finds application in the majority of the passenger car segments. Given the increasing adoption of HUD in the automotive sector, it has become a standard feature for various models in the luxury car segment. Additionally, the increasing demand for comfort and safety has compelled automakers to incorporate this feature in premium and mid segment models as well.

The market in growing regions such as Asia-Pacific, and North America indicate promising growth potential for the automotive HUD market. The Asia-Pacific automotive market in particular presents high-growth opportunities; the region includes Japan, China, and India, with the latter two having huge production capabilities.

The European HUD market is primarily driven by the growing awareness regarding driver safety and convenience. Europe has many luxury/premium car manufacturers. Major high-end car OEMs such as Audi AG (Germany), BMW (Germany), Mercedes-Benz (Germany), Bentley Motors (UK), Maserati (Italy), Ferrari (Italy), and Bugatti Automobiles (France) have their headquarters in Europe.

The automotive HUD comes as standard safety feature in the majority of European automobiles. The region therefore has a wide customer base for this technology. Windshield head up display technology and combiner head UP display technology The windshield head up display projects a virtual image with the necessary information needed by the driver.

This information is projected in accordance with the drivers eye gaze. In this technology type, the windshield of the car plays an important role as there are chances that the image produced by the device can be distorted. The conventional HUD uses TFT displays which projects images on the windscreen.

• With the advancement in technology there have been improvements in the display technology.
• One of the differentiating factors between the two types of HUDs is the space requirement and image resolution.
• The Combiner HUD type has a smaller screen which displays the necessary information but lacks the picture quality as compared to the other type.

The Combiner HUD has an adjustable positioning system which enables the driver to adjust the screen according to their convenience. Augmented Reality head up display technology Augmented reality (AR) is an upcoming trend in the head-up display market. Augmented HUD is a real time technology which enhances the safety and driving experience. Augmented reality-based HUD technology provides full-colour advanced driver assistance system (ADAS) including lane departure warning system and advanced driving information.

The AR-HUD sense the exterior environment of the vehicle, analyses this information and virtually display the traffic condition. For example, if the driver has set a destination on the navigation system, the AR-HUD projects a virtual route that is to be followed. It also detects the distance between itself and the vehicle in front and alerts the driver.

The differentiating factor for AR-HUD is that it projects information which appears to be part of the driving situation itself. : Active and passive automotive safety systems

What are the examples of active and passive safety systems?

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 are two types of safety systems?

Types – There are 2 main types of industrial safety systems in process industry:

• Process safety system (PSS) or process shutdown system (PSS).
• Safety shutdown system (SSS): This includes (ESD) and emergency depressurization (EDP) systems.

A third system also exists which acts as a barrier and contains the spray out of hot oil & gases from flanges, valves & pipe joints. These systems are popularly known as safety spray shields and flange guards. The use of spray guards is mandated by,

Are airbags active or passive?

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.

1. All of these features, among others, are put in place to help drivers avoid accidents.
2. Passive safety features, on the other hand, are meant to limit the damage of a collision that does occur.
3. Some accidents are simply unavoidable.
4. When they happen, it’s good to know that you have some protection.
5. 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 an example of a passive safety system?

Passive safety systems prevent the driver and passengers from getting injured by reducing the impact of the crash. Some of the common passive safety features are seatbelts, airbags, ISOFIX mounts, crumple zones, etc

Which is a passive safety system?

Passive safety systems protect the occupants of a vehicle and other road users if a crash occurs. They do this by reducing the impact of an accident or the level of injury. In other words, passive safety technology is all about mitigating the consequences of an accident during and after impact, as from the moment that first contact is made. Sometimes these measures are referred to as ‘secondary’ safety technology.

What is an example of passive safety?

More Protection at the Right Moment – Every day, accidents happen on the roads where the risk of serious accidents can be reduced thanks to passive vehicle safety. Modern aids not only provide support during driving; they also contribute to the safety of the occupants.

Are seat belts active or passive?

Passive Systems Came First – A passive safety system only works when a collision, rollover, or other vehicle upset occurs. Seat belts are a great example of a passive safety system. The lap and shoulder harness helps to keep you and any passengers wearing seat belts secured to your seats.

1. That restraint helps to stop people from getting thrown from cars or flung forward or to the sides during a violent collision.
2. Virtually all states have laws that require you to wear a seat belt while traveling in a vehicle.
3. That seat belt is the first mandated safety feature in any vehicle.
4. About 60 years ago, seat belts were not mandated by the federal government.

Seat belts were included as standard equipment only on relatively few new cars. And the ones that were included usually only had a simple lap restraint. The Federal Motor Vehicle Safety Standard in 1968 required automakers to include seat belts as standard equipment on all new vehicles.

Is traction control active or passive?

Active Safety – An active safety feature (or active system) works to prevent an accident before it happens and ultimately not only protects the occupant but also the public. These systems continuously monitor the driving environment to help you stay safe and are designed to keep you from having an accident.

Electronic Stability Control (ESC) Traction control (such as Anti-Skid or Anti-Slip Regulation – ASR) Anti-lock Braking Systems (such as ABS) Hill control (or Hill Start Assist, preventing rollbacks on inclined slopes) Cruise control

What is active safety and passive safety?

As technology advances, the automobile industry continues to strive to make cars and trucks safer. Ever since the invention of the motorized vehicle, manufacturers have attempted to make it safer for drivers and passengers. But as the car and truck accident statistics show each year, we still have a long way to go.

There are still too many people being seriously injured or killed in car accidents every year on our roads and highways. But every year, newer model vehicles become safer. For most of the history of the automobile, car designers focused on passive safety devices and systems. However, over the past few decades, the focus has been to incorporate active safety features, devices, and systems into the design of new vehicles.

A passive safety feature is any safety system that reacts to a collision and attempts to keep occupants safe, but only after a collision occurs. Active safety features are those that attempt to avoid collisions altogether.

What is the difference between active and passive safeguard systems?

The Difference Between Active and Passive Fall Protection The Difference Between Active and Passive Fall Safety According to, employees falling accounts for the greatest number of fatal construction injuries. This finding agrees with the OSHA statistic: providing adequate fall protection is the most often ignored OSHA regulation.

• The Fall Safety Hierarchy The best practices of all workplaces involving altitude include the implementation of an extensive fall hazard protection system.
• In the fall safety hierarchy, precedence is given to the elimination of hazard itself over all other methods.
• If not possible, next in line is securing the site parameters by the installation of a Passive Fall Protection System, and then – as the last option – an Active Fall Arrest System.

Where Is Fall Safety Required? As prescribed by Occupational Safety and Health Administration (OSHA), all workplaces involving elevation or altitude must execute a fall safety program. There are varying height limits for different types of workplaces – if the aforementioned height limits are reached or exceeded, employers must apply precautionary measures.

Four feet for industrial workspaces Five feet for shipyards Six feet for construction sites Eight feet for long-shoring

OSHA requires all workplaces operating dangerous equipment or machinery to set up precautionary measures, no matter how little the elevation.The goal is worker’s safety: anything that is potentially dangerous must be protected against.To better implement fall safety measures, we need to first understand the differences between the fall safety systems. Passive Fall Protection System vs. Active Fall Arrest Systems

A passive fall protection system encompasses all protective measures that are in essence static, fixed, or unmoving. There is no human interaction with the system involved after installation and there is no need of personal protective gearing. As stated above, these are installed as the second line of defense against fall.

Commonly administered passive protection systems include barricades, guardrails, netting, and so on. Active fall protection systems on the other hand involve active participation of the worker, are movable, and require the use of special gearing. These systems comprise of a body harness, lanyard, an anchor, lifeline, and connectors such as snap hooks.

There are multiple variations of a fall arrest and restraint system available, but all have these parts in common. There are a few things that are a prerequisite and must be taken care of if active fall protection is intended. The first and foremost is training.

1. Untrained or unauthorized persons must not use active fall safety.
2. Before every use, it is recommended to go through a simple and easy to execute rescue plan in the event of a fall.
3. Workers must thoroughly check each and every equipment and its parts regularly to ensure fall protection is secure and in place.

Inappropriately used active fall protection can be not only ineffective, but dangerous. Make sure the right equipment is installed. For example, use anchorage as rated for the number of users. Active fall safety systems comprise of different types of equipment.

For example, there are self-retracting life lines and shock absorbing lifelines available – you can select the appropriate one according to the total fall distance available at the site. This distance can be calculated by adding the following lengths: free fall distance + distance harness stretches + height of the worker + elongation distance of the arresting device + buffer distance.

More Protection at the Right Moment – Every day, accidents happen on the roads where the risk of serious accidents can be reduced thanks to passive vehicle safety. Modern aids not only provide support during driving; they also contribute to the safety of the occupants.

What is an example of an active sensor in a car?

Automotive sensors fall into two categories: active and passive sensors. Active sensors send out energy in the form of a wave and look for objects based upon the information that comes back. One example is radar, which emits radio waves that are returned by reflective objects in the path of the beam.
