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–
