During selection of EV mode, in order to suppress capacitor deterioration while ensuring engine start, the hybrid vehicle control device has a drive system including a starter motor (1), an engine (2) and a motor/generator (4), and a power supply system including a high power battery (21), a capacitor (23), and a hybrid control module (81) which controls charging and discharging of the capacitor (23). The hybrid control module (81) performs a starter start-up control, a motor-generator (M/G) start control and charging and discharging control: during EV mode, when the operating point in accordance with the vehicle speed and required driving force is present in a M/G start-up region (A), the hybrid control module (81) maintains the capacitor voltage at or below a deterioration free voltage (b), and when the operating point is deviated from the M/G start-up region (A), the hybrid control module (81) recharges the capacitor to or above a starter start-up permission voltage (a). |
