Abstract
A control device for a hybrid vehicle is provided, which executes charging of a capacitor when a depth-of-discharge of a capacitor exceeds a predetermined depth-of-discharge which is set based on a vehicle speed. The control device of the hybrid vehicle, provided with an engine, a motor for assisting the output of the engine, and a capacitor for supplying electric power to the motor and for storing regenerative energy, comprises a depth-of-discharge detecting device (S063) for detecting a depth-of-discharge DOD of the capacitor, wherein when the depth-of-discharge DOD of the capacitor falls below the depth-of-discharge limit value DODLMT (053), the capacitor is charged so as to recover the depth-of-discharge of the capacitor.
