An accident seldom occurs in isolation. Following an initial collision, a vehicle often strays into oncoming traffic and collides with other vehicles as a result. In a situation as precarious as this, the multi-collision brake unfolds its full potential: It automatically applies the brakes, which can save the shocked driver and other road users from further harm.
The electronic assistant decelerates the vehicle so it comes to a stop. To do so, it connects up other systems that are already installed in the vehicle. The airbag sensors detect the first accident and send the brake command to the brake control unit. The latter then initiates a full application of the brakes with the aid of the electronic stability control ESC.
