ABSTRACT:
A vehicular drive unit having a combustion engine, a motor-generator for converting electric energy coming from a battery into mechanical energy to output the converted mechanical energy or for converting mechanical energy into electrical energy to store the converted electrical energy in the battery, and a planetary gear including at least three rotary elements. The vehicular drive unit further includes a continuously variable transmission for changing the revolution of an input member continuously variably to output the changed revolution to the drive wheels of the vehicle. The planetary gear has a first rotary element connected to the output shaft of the combustion engine, a secondary element acting in reaction against the first rotary element and connected to the motor-generator, and a third rotary element connected to the input member of the continuously variable transmission.
