Abstract

A distance-related cruise control system for motor vehicles has an electronic control unit, by which in the event of a distance-controlled following travel with a defined following distance from a vehicle driving ahead, when the speed of the vehicle falls below a defined first threshold, in the event of a further decrease of the speed of the vehicle driving ahead, the deceleration capability is reduced independently of the maintenance of the following distance. Preferably, the momentarily defined following distance is first increased when the speed falls below a defined second threshold which is larger than the first threshold.
