<P>PROBLEM TO BE SOLVED: To provide a controller capable of inhibiting passage of an overcurrent and inhibiting the overshooting of flow rate even when an electric pump, provided to assist a mechanical pump driven by an engine, is operated before stopping the engine. <P>SOLUTION: The electric pump is operated before stopping the engine by the control of a motor current by adjusting an applied voltage of a motor. When shift stages to the electric pump following the rotation stop of the engine are judged by engine rotation speed, motor rotation speed, a downstream side pressure of a one-way valve provided at the discharge side of the electric pump, etc. the control of the motor current by the adjustment of the applied voltage of the motor is shifted to the control of motor rotation speed by the adjustment of the applied voltage of the motor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
