Abstract
A hybrid vehicle in which, by using a continuously variable transmission inserted between output shafts of a heat engine such as an internal combustion engine and an electric motor as a torque distributor, the torque acting upon the driving wheels is distributed to the two and the distribution ratio between the engine and motor is changed, and control is performed so that the speed and/or torque of the heat engine becomes a predetermined constant value and the exhaust emission and fuel consumption are enhanced.
