Abstract
A control apparatus of a hybrid vehicle is provided, capable of charging the battery device when the state of charge of the battery device tends to decrease and the initial state of charge of the battery device is reduced by a predetermined amount. The present device comprises a lower limit threshold value setting device S, an upper limit threshold value setting device for setting the lower limit and upper limit threshold values of the discharge amount of the battery device, a mode setting device Sfor increasing the state of charge when the state of charge is reduced to the lower limit threshold value, a mode setting release device Sfor releasing the mode setting changed by the mode setting device, and a discharge depth detecting device Sfor detecting the discharge amount of the present state of charge by comparison with the initial state of charge. The threshold value for determining whether it is necessary for the motor to assist the engine is modified depending upon the discharge depth.
