ABSTRACT:
A vehicle power transmission apparatus having an engine starting function is provided which is small in size and has a high degree of freedom and accuracy in controlling torque transmission. The apparatus comprises torque transmitting means including a differential gear mechanism and having at least three (first through third) rotation shafts; an engine operatively connected with the first rotation shaft of the torque transmitting means; a transmission connected with the second rotation shaft for transmitting torque to a drive shaft of the vehicle; an electric motor connected with the third shaft of the torque transmitting means; a power transducer for controlling the electric motor; an electric power source for supplying power to the electric motor through the power transducer; and a controller for controlling the power transducer in such a manner that the electric motor operates as a power source or a load in dependence upon the operating condition of the vehicle.
