| Zusammenfassung: | The invention relates to a method for establishing the position of an actuating unit which is operated by an electric motor, in which a motor speed is determined from a motor model, the speed is integrated over a period of time and the position of the actuating unit is determined by multiplying the result of the integration by a proportionality factor. The motor model takes account of afterrunning of the electric motor at the instant of switch-off. The invention also relates to actuating units, brakes, pumps and transmissions for which the method can be used. |
