A hybrid vehicle includes an electric motor and an internal combustion engine, and can operate in an independent electric motor drive mode and a hybrid drive mode. For this purpose, the vehicle also includes a control unit that controls the operation of the electric motor and the internal combustion engine. The control unit comprises a controller and a plurality of sensors providing information relating to vehicle operation. The controller preferably controls the drive force produced by the motor to reduce the jolt experienced by the vehicle when the engine is engaged during the hybrid drive mode, thereby reducing driver discomfort. Additionally, the controller controls the charging of the battery during all modes of vehicle operation and adequately controls the ratio of the drive force from the motor and the engine that is transmitted to the drive wheels. The controller also preferably controls the increased recovery of kinetic energy from the harnessing of the inertia of the engine during engine shut-off to generate electric power to charge the battery.
A control unit for a hybrid engine having an electric motor and an internal combustion engine generating a motor drive force and an engine drive force, respectively, to drive at least one drive wheel on a hybrid vehicle, the unit comprising:
