Method for the Cruise and/or Range Control of Motor Vehicles
First Claim
1. A method of operating a range-controlled cruise control system of a motor vehicle, the method comprising the acts of:
- as a function of specific data of a target object driving ahead, determining a first desired pre-acceleration value for achieving a predefined distance with respect to the target object driving ahead;
as a function of specific data of a front object driving ahead, which front object is traveling in front of the target object, determining a second desired pre-acceleration value for achieving a predefined distance with respect to the front object driving ahead;
determining a desired acceleration value for the motor vehicle from the first desired pre-acceleration value and the second desired pre-acceleration value by weighting the first and second desired pre-acceleration values; and
outputting a torque demand based on the desired acceleration value to a drive unit or a brake unit of the motor vehicle.

Abstract
A method for cruise and/or range control of motor vehicles with range-controlled cruise control systems, wherein, during a determination of a desired acceleration value, for reaching a predefined speed and/or a predefined distance to a target object traveling ahead during a following travel, specific data of a target object traveling ahead and of a front object traveling in front of the target object are taken into account. As a function of the specific data of the target object driving ahead, a first desired pre-acceleration value is determined and, as a function of the specific data of the front object driving ahead, a second desired pre-acceleration value is determined. From the first desired pre-acceleration value and the second desired pre-acceleration value, by weighting the two desired pre-acceleration values, the relevant desired acceleration value is determined.
