Question 5570
How does the autonomous emergency braking system "AEB" act if you do not react to an obstacle in the roadway or a pedestrian crossing it?
- It contacts the emergency services.
- It stops the vehicle on the shoulder.
- It emits an audible warning, and if you do not respond, it takes control of the vehicle to stop it.
Show answer and explanation
Correct answer: It emits an audible warning, and if you do not respond, it takes control of the vehicle to stop it.
If AEB detects that you’re going to hit an obstacle or a pedestrian crossing the road, it warns you first, usually with a beep. If you don’t react or don’t brake hard enough, it takes control and brakes to stop the car or at least reduce the impact, as it would for the man crossing with a cart in the image. It doesn’t turn the steering wheel, so it won’t take you onto the shoulder, and calling emergency services is eCall’s job.
