<P>PROBLEM TO BE SOLVED: To cope with a problem wherein it is desirable to well prepare for any contingency such as a drop of a power-supply voltage since an electric parking brake device has a characteristic electrically controlled. <P>SOLUTION: An electric actuator 30 actuates a parking brake 14 when a braking is required in the electric parking brake device 150. An actuator control means 102 controls an actuation and a release of the parking brake 14 by controlling the operation of the electric actuator 30. A state storage means 106 stores a control state of the parking brake 14. The actuator control means 102 restarts the incomplete control when the control state of the parking brake 14 stored in the state storage means 106 indicates the incomplete control of actuation or release of the parking brake 14. <P>COPYRIGHT: (C)2007,JPO&INPIT |
