ABSTRACT:
A device for the longitudinal guidance of a motor vehicle, having a speed sensor for measuring the driving speed of the vehicle; a distance sensor for measuring the distance to an obstacle possibly located in front of the vehicle; and a controller, which intervenes in the drive and brake system of the vehicle and regulates the driving speed, possibly as a function of the distance to the obstacle, in a closed-loop control circuit if the vehicle speed is above a certain limit speed, characterized by a control device, which intervenes in the drive and brake system in a controlling manner at driving speeds below the limit speed.
