Abstract
An in-vehicle power transmission apparatus is equipped with a motor-generator working as an engine to drive a vehicle and a power split device made up of a plurality of power split rotors. A first one of the rotors is coupled to a driven wheel of the vehicle, while a second one of the rotors is coupled to an accessory such as an air compressor of an air conditioner. The speed of the second rotor is controllable independently of that of the driven wheel. This eases restrictions on the supply of power produced by the generator-motor to the accessory. Alternatively, the rotors are so linked that when the speed of the first rotor is not zero (0), the speed of the second rotor has one of zero (0) and a value other than zero (0), thus ensuring the stability in supplying the power to drive the vehicle to the accessory.
