Abstract
A distance controller having an automatic stop and/or start function for motor vehicles, having a distance-measuring remote region sensor, a distance-measuring ultrasound sensor, and a control unit designed to intervene in the longitudinal guiding of the home vehicle as a function of the distance, measured by the remote region sensor, from a vehicle traveling ahead. If the measured distance is smaller than the range of the ultrasound sensor, on the basis of the signal of the ultrasound sensor it is verified whether this sensor is functional. If yes, the signal of the ultrasound sensor is evaluated in the context of the stop and/or start function. According to the present invention, the stop and/or start function has an operating mode in which a distance controlling takes place on the basis of the signal of the ultrasound sensor. In this way, the distance from the vehicle ahead can be reduced during stop and go operation.
