Abstract
A hybrid vehicle that is provided with an engine and a motor generator as power sources, includes a clutch which automatically engages or disengages to cause or interrupt rotation transmission between the output shaft of the engine and the input shaft of a transmission, a power transmission mechanism which transmits power between the input/output shaft of the motor generator and the input shaft of the transmission, and a hybrid control unit which selectively disengages the clutch and drives the motor generator. The clutch is disengaged according to running conditions, and the rotation speed of the motor generator is varied by the transmission to drive the vehicle. In this way, the region in which the motor generator operates efficiently is expanded, and fuel consumption by the hybrid vehicle is reduced.
