Abstract:
1. A hybrid motor vehicle comprising: an internal combustion engine that outputs motive power for vehicle traction; an engine-motoring electric motor that motors the internal combustion engine; a vehicle traction electric motor that outputs motive power for vehicle traction; a secondary cell that supplies electric power to the engine-motoring electric motor and to the vehicle traction electric motor; and a pre-engine-start control device that controls the internal combustion engine and the engine-motoring electric motor so as to motor the internal combustion engine in a reverse rotation direction without performing fuel injection nor ignition during a post-system-start electric traction travel during which the hybrid motor vehicle is traveling on motive power from the vehicle traction electric motor without operating the internal combustion engine after a system of the hybrid motor vehicle is started; wherein the pre-engine-start control device controls the internal combustion engine and the engine-motoring electric motor so that the internal combustion engine is motored in the reverse rotation direction at a rotational speed within a range of 500 rpm to 2000 rpm, for a duration within a range of 1 second to 20 seconds, if the internal combustion engine is motored in the reverse rotation direction during the post-system-start electric traction travel.
