Abstract

A method and a device for automatically triggering a deceleration of a vehicle so as to prevent a collision with another object. Objects in the range of the vehicle's course being detected using signals of an apparatus for sending and receiving radar signals or lidar signals, or of an apparatus for receiving video signals. An endangerment potential is determined as a function of the objects detected, and when a predefined endangerment potential theshold value, which may be less than the triggering threshold value for the deceleration, is exceeded, the deceleration means of the vehicle are reset to a state in preparation for braking. Furthermore, additional vehicle functions may be carried out when the endangerment potential threshold value is exceeded, whereby passenger safety in this travel situation is enhanced.
