Based on the Telligent proximity sensor system, Active Brake Assist is designed to prevent rear-end collisions. Using continual proximity measurements and the speed relative to a preceding vehicle, the electronics can determine when a crash will occur unless the traffic situation changes or the driver intervenes. In such a case, the system goes into action. First it warns the driver both optically and acoustically of the impending danger.
If the driver doesn’t react, it actuates a 30 percent partial braking action to reduce the energy of the vehicle and to increase the intensity of the warning. Only if the driver still fails to react do the electronics trigger an emergency braking action. | ||||||
