The invention discloses a power transmission apparatus and a control apparatus therefore. The power transmission apparatus can drive an engine to obtain a necessary and sufficient driving force while charging is limited. The power transmission apparatus allocates the power output by the engine to a drive wheel side and an engine side through a differential mechanism, uses the electricity generated by the engine to drive an electric motor so as to output the torque of the motor towards the drive wheels, and charges at least one part of the electricity generated by the engine to an electrical storage apparatus. The motor is configured to be disposed at a position apart from a transmission path along which the dynamic power the engine is transmitted to the driving wheel. The motor and the transmission path are configured with a fluid coupling therebetween. When the charge of electric storage apparatus is restricted, a fluid coupling is differentially rotated and the electric motor is driven to generate power loss.
