摘要

A method for carrying out a driver-independent brake force holding function in a motor vehicle when the motor vehicle is at a standstill on a roadway that is inclined in the vehicle longitudinal direction. The brake force, maintained independently of the driver, is reduced when a release condition is met. In the method, the uphill distance, which corresponds to the spacing or the distance from the neighboring vehicle in the uphill direction, is ascertained with the aid of a first distance sensor system. If the uphill distance falls below a predetermined limiting value, the brake force is reduced before the release condition is met, so that the motor vehicle moves.
