Abstract:
A hybrid vehicle, comprising:a drive wheel, a transmission having input and output shafts, the transmission varying the rotation speed ratio between the input shaft and the output shaft, and transmitting the rotation of the output shaft to the drive wheel, an engine having an output shaft, a clutch which engages/disengages the output shaft of the engine and the input shaft of the transmission, a motor generator which has an input/output shaft and which functions both as a motor and a generator, a power transmission mechanism which transmits rotation between the input/output shaft of the motor generator, and the input shaft of the transmission, a power storage element which stores the power supplied by the motor generator, running-by-motor control means which disengages the clutch according to running conditions and drives the motor generator, a brake which applies a braking force to the vehicle, braking detection means which detects braking of the vehicle, and regeneration control means which engages the clutch and causes the motor generator to regenerate power during sudden braking, and which disengages the clutch and causes the motor generator to generate power during slow braking.
