Abstract

The present invention relates to a method for controlling the speed of a motor vehicle and the distance of the motor vehicle to least one motor vehicle driving ahead, where at least the speed v of the motor vehicle and the distance a to the motor vehicle driving ahead are determined with the aid of a detector having a distance sensor, where the traveling speed v is adjusted in response to the measured distance a deviating from a setpoint trailing distance as, and where the engineering problem of controlling the speed and the distance of a motor vehicle to least one preceding motor vehicle is solved in both a simple and reliable manner, in that an intervention distance ai′ is determined which is less than the range of the distance sensor, and that the traveling speed v is adjusted at a distance a which is less than the intervention distance ai.
