<p><P>PROBLEM TO BE SOLVED: To prevent power shortage from occurring in a battery for supplying power to an electrically operated supercharger and a motor-generator in a vehicle with an engine mounted with a motor-operated supercharger. <P>SOLUTION: The control unit 20 controls the motor generator 11 so that charging capacity of the battery 15 for supplying power to the motor-operated supercharger 5 and the motor generator 11 as a vehicle power-source attains a target charging capacity. Further, the control unit 20 computes the frequency of driving the motor generator 11 as a vehicle power-source for the motor-operated supercharger 5 and the vehicle, and corrects higher the target storage charge of the battery 15, as the frequency of driving is higher. The control unit 20 corrects further so that as the rotary speed of the engine 1 at the time of drive-control of the motor generator 11 as a power-generator is lower, so the target charging-capacity of the battery 15 is higher. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
