1. A cruise control system for vehicles, including motor vehicles, comprising:
- a sensor device for determining movement data and position data of an object located in a sensing range of said sensor device; and
an evaluation unit connected to said sensor device, said evaluation unit receiving and processing the movement data and the position data of the object determined by said sensor device and further receiving and processing vehicle data on a movement of a vehicle, said evaluation unit regulating at least one of a velocity and a direction of travel of the vehicle in dependence on the movement data, the position data and the vehicle data, said evaluation unit determining a tracking probability P being a measure of a control-related quality of a detection of the object, the velocity and the direction of travel of the vehicle being regulated in dependence on the tracking probability P such that as the tracking probability P rises a degree of control being intensified, the tracking probability P depending on at least one of the following variables;
variable fT being a number of measurement cycles passed through since a detection of the object;
variable fA being a stability of a sensor signal reflected by the object;
variable fD being a quality of a distance determined from the vehicle to the object;
variable fV being a quality of a relative velocity determined between the vehicle and the object;
variable fW being a quality of an angle determined between the direction of travel of the vehicle and the direction of travel of the vehicle with respect to the object; and
variable fP being a probability of the object being located in a path of the vehicle.

Abstract
A cruise control system with a sensor device and an evaluation unit. The sensor device determines movement data and position data of an object. The evaluation unit processes the movement and the position data of the object and data on the movement of the motor vehicle itself. The velocity and/or a direction of travel of the vehicle are regulated as a function of the data. A tracking probability P is determined which is a measure of a control-related quality of the detection of the object. The velocity and/or direction of travel of the vehicle are regulated as a function of the tracking probability.
