Abstract: The invention relates to a method and a device for preventing rear end collisions with a vehicle. According to the invention, the distance (d) and/or speed (vrel) of the vehicle in relation to the vehicle in front are determined by means of an environmental sensor (2) oriented towards the front region of the vehicle.

In the event of a risk of collision, the drive train (10) and/or the delay devices (11) of the vehicle are engaged in order to reduce the risk of collision and/or driver warning devices (12, 5) are triggered in order to inform the driver about the risk of collision.
