1. A control apparatus for a hybrid vehicle including an internal combustion engine and a generator motor that are used as power sources of a vehicle, a capacitor that supplies and receives electrical energy to and from the generator motor, and a driving force assisting unit that assists a driving force of the internal combustion engine by a driving force of the generator motor when a driving force command of the vehicle is larger than a predetermined determination threshold value, the control apparatus comprising:

  • a gradient acquisition unit that acquires an ascending gradient of a traveling road for the vehicle;

    a threshold value increasing unit that increases the predetermined determination threshold value when the ascending gradient acquired by the gradient acquisition unit is larger than the predetermined gradient; and

    a generated power changing unit configured to;

    increase an amount of generated power with an increase of the ascending gradient acquired by the gradient acquisition unit when the ascending gradient is a predetermined threshold gradient or less, anddecrease the amount of generated power with the increase of the ascending gradient when the ascending gradient is larger than the predetermined threshold gradient.
