ABSTRACT:
The invention relates to a method for controlling speed and/or distance in motor vehicles having distance-related longitudinal control systems, wherein during clear driving, a clear drive acceleration value is set to reach a preset speed, and while following a detected target object, a following acceleration value is set to maintain a preset distance from the target object, and wherein if the target object is lost during a following drive operation, a transition acceleration value is set. According to the invention, the transition acceleration value is set for the duration of a time interval, which is dependent on the speed at the time of the target object loss.
