Distance-related cruise control system
First Claim
1. A distance-related cruise control system having a maximal deceleration limit for a first motor vehicle, comprising:
- an electronic control unit which includes a first means for, in an event of a distance-controlled following travel with a defined following distance from a second vehicle driving ahead, reducing the maximal deceleration limit of the first vehicle independently of maintaining said defined following distance when a speed of the second vehicle ahead falls below a first defined threshold (S1) in an event of a further decrease below said first defined following distance of the speed of the vehicle driving ahead.

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.
