The invention provides a control apparatus for a vehicle. Generated power during decelerated travel can be ensured without bringing discomfort to a passenger. The control apparatus for a vehicle includes an engine and includes an electric generator, a throttle valve, an electric generator control unit, and a throttle control unit. The electric generator is configured to be coupled to the engine. The throttle valve is configured to control an amount of intake air of the engine. The electric generator control unit is configured to allow the electric generator to perform regenerative power-generation on decelerated travel of the vehicle. The throttle control unit is configured to control the throttle valve openwise on the decelerated travel. The electric generator control unit is configured to cause an increase in power-generation torque Tg of the electric generator, upon a switchover of the engine from a fuel cut state to a fuel injection state on the decelerated travel.
