List of Active Car Safety Features - How Do They Work?

ABS with EBD

ABS is one of the most important features and helps you stop your brakes locking up when you have hit on them to avoid a potential accident. They stop from the brakes being locked and also help in areas where there is less traction like wet surfaces and more. ABS also helps you steer your car carefully to avoid hitting a car. EBD is part of that as it is there to check the load of pressure on each wheel. It is standard on all cars.

Electronic Stability Control (ESC)

It is there to help your car to stop skidding on a wet surface and also help your car get stability. When the car loses grip and traction, the ESC helps in applying brakes.

Autonomous Emergency Braking (AEB)

It is a step up in safety as it steps in to prevent a collision and avoid an accident. It automatically applies the brakes to save the car in-case the driver does not do it in time.

 

Lane Departure Warning (LDW)
