ABSTRACT:
A control system for a vehicular drive unit comprising: an engine, a motor generator connecting to the output of the engine and acting as a power generator for recovering the energy from the wheels and as a motor for driving the output shaft of the engine, a battery for storing the energy recovered by the motor generator as electric power and for supplying electric power to drive the motor generator, a first clutch for connecting the motor generator and the wheels, stopping state detecter for detecting a stopping state of the vehicle, and a controller for controlling the engine, the motor generator and the first clutch. When the stopping state is detected by the stopping state detector, the controller releases the first clutch, sets the supply of a fuel to the engine to a predetermined rate lower than that of an idling RPM, and feeds electric power to the motor generator to maintain the rotation of the engine substantially at an idling RPM by the drive of the motor generator.
