A control apparatus for a power transmitting system of a four wheel-drive vehicle, which includes a first drive power source, a second drive power source, and a central differential mechanism disposed between the first and second drive power sources. The central differential mechanism has an input rotary element and a pair of output rotary elements and is constructed to distribute an output of the first drive power source received by the input rotary element, to the pair of output rotary elements to transmit the output of the first drive power source to front wheels and rear wheels of the vehicle. The second drive power source is disposed in a power transmitting path between one of the pair of output rotary elements and the front or rear wheels. The control apparatus includes a coupling device disposed between the pair of output rotary elements, and drive force distribution changing unit which changes drive force distribution to the pair of output rotary elements by changing a drive force generated by the second drive power source and an engaging capacity of the coupling device.
