Abstract
A device for holding the braking force of a motor vehicle has a braking force holding valve in a brake operating fluid circuit. The device ascertains whether a load is imposed on an engine of the motor vehicle based on detected signals indicating the amount of depression of an accelerator pedal and the rotational speed of the engine. When there is a load acting on the engine, the braking force holding device is opened to release a braking force.
