Abstract
A method and a device for controlling the braking torque of a brake force controller at at least one wheel of a motor vehicle, in which the control pulses for a hydraulic valve is not calculated as a function of the control signal of the hydraulic pump (pump motor PM) but of the actual standstill of the pump motor PM. To detect the actual standstill of the pump motor PM, its induced voltage &mgr; is measured. When voltage &mgr; falls below a predefined minimum threshold value V , then the pump motor PM is assumed to be at a standstill.
