System and method for operating a motor vehicle with a brake holding assist
First Claim
1. A method for determining a brake torque reduction parameter for brake torque reduction in a motor vehicle with a brake holding assist function comprising:
- detecting at least one motion parameter of the motor vehicle;
comparing the at least one detected motion parameter with a predetermined threshold value of said motion parameter;
determining a correction value for at least one initial brake torque reduction parameter when said at least one detected motion parameter differs from said predetermined threshold value of said motion parameter;
adjusting the at least one initial brake torque reduction parameter using the correction value to determine at least one optimized brake torque reduction parameter;
wherein the at least one brake torque reduction parameter is a point in time of a brake torque reduction, the at least one initial brake torque parameter is an initial point in time of a brake torque reduction, and the brake torque reduction point in time correction value; and
using the at least one optimized brake torque reduction parameter as a brake torque reduction parameter for the brake torque reduction and changing the point in time of the brake torque reduction and correspondingly the point in time of a vehicle brake release.

Abstract
Determining a brake torque reduction parameter for brake torque reduction in a motor vehicle having a brake holding assist function. The determination including detecting a motion parameter of the motor vehicle and analyzing the detected motion parameter to determine a correction value for a brake torque reduction parameter. Adjusting the brake torque reduction parameter using the correction value determines an optimized brake torque reduction parameter. The optimized brake torque reduction parameter is used as a brake torque reduction parameter of the brake torque reduction.
