Claim Text:
1. A control apparatus for a hybrid vehicle comprising: an engine, a first electric motor connected to the engine, a second electric motor connected to wheels of the hybrid vehicle, an electric-energy storage device for supplying an electric energy to the first and second electric motors, a clutch interposed between the engine and the wheels and configured to selectively place a power transmitting path therebetween in a power transmitting state and a power cut-off state, and a controller that controls a running state of the hybrid vehicle, wherein the controller selectively establishes one of a first drive state in which a vehicle drive force is generated primarily by the second electric motor operated with the electric energy supplied from the electric-energy storage device while the engine is placed in a rest state, and a second drive state in which the power transmitting path between the engine and the wheels is placed in the power cut-off state by the clutch while the first electric motor is operated with a drive force of the engine to generate an electric energy and in which the vehicle drive force is generated primarily by the second electric motor operated with at least one of the electric energy generated by the first electric motor and the electric energy supplied from the electric-energy storage device, and the controller controls the hybrid vehicle such that a slope of variation of the vehicle drive force generated in the second drive state with an operation variation amount of an accelerator pedal is different from that of the vehicle drive force generated in the first drive state with the operation variation amount, and such that the slope of variation of the vehicle drive force generated in the second drive state is larger than that of the vehicle drive force generated in the first drive state.
