forward collision mitigation (FCM)

Forward Collision Mitigation (FCM) is a radar-based driver assistance system

that monitors the distance to the vehicle in front and triggers braking if there is a sudden reduction. Forward Collision Mitigation FCM) helps drivers avoid rear-end collisions. The FCM system uses a radar system

to monitor the speed of the vehicle in front. If the vehicle in front reduces its driving speed and the distance between the vehicles is reduced relatively quickly, the FCM system triggers a warning signal. If there is a further rapid reduction in the distance between the two vehicles, then there is a risk of a collision. The FCM system enters a braking mode and slows down the driving speed. If, despite the triggered braking process, there is a further reduction in the distance between the two vehicles and a collision appears extremely likely, then the FCM system triggers a strong braking process. Both braking processes are accompanied by the warning signal. The parameters for triggering the warning signal and the braking processes are the driving speed and the change in differential speed.
