Beschreibung
Zusammenfassung:	A control apparatus for an electric parking brake, including an electric motor to generate a brake force by contacted friction materials upon a brake request, includes a no-load current detection unit to detect a current with the no-load electric motor; a voltage monitor unit to detect a voltage applied to the electric motor monitored between two points on a power line; a resistance calculation unit to calculate a resistance between two points based on the no-load current and the monitored voltage; a required voltage calculation unit to calculate a required voltage between the two points required for driving the electric motor to generate the brake force based on the resistance and a target current; and a control unit to flow a current over the target current in the electric motor based on a comparison between the required and monitored voltages.
