Abstract
In order to effectively prevent generation of a counter electromotive voltage during cruising, the present invention provides a control system of a hybrid vehicle comprising an engine, motor, and a capacitor, including an engine rotational speed sensor for detecting the engine rotational speed NE, a target voltage setting device for setting a charge target voltage (target capacitor voltage), and a motor ECU for controlling the charge of said power storage unit. A target capacitor voltage VCAPCMD is set based on the detected engine rotational speed NE (step S ), and when the capacitor voltage VCAP<the target capacitor voltage VCAPCMD (step S is “YES”), a charging operation is executed until the target capacitor voltage VCAPCMD≦the capacitor voltage VCAP. Thereby, it is possible to maintain the counter electromotive voltage<the capacitor voltage.
