An engagement operation of a dog clutch is carried out while an engagement operation of a second clutch is being carried out, that is, during a situation that an uplock is hard to occur because of a phase shift generated between meshing counterpart members of the dog clutch. Thus, the dog clutch is easily engaged, and it is possible to facilitate preparation for transmission of power through a first power transmission path. If the dog clutch is not engaged, the second clutch is engaged and a second power transmission path is established, so it is possible to start moving a vehicle by transmitting power through the second power transmission path. Thus, when the dog clutch is in a non-engaged state at the time of an N-to-D shift during a stop of the vehicle, it is possible to ensure the startability of the vehicle.
A control apparatus for a power transmission system, the power transmission system including at least a first power transmission path and a second power transmission path provided in parallel with each other between an input rotating member, to which power of a driving force source is transmitted, and an output rotating member that outputs the power to a drive wheel, the first power transmission path being established when an intermesh clutch and a first friction clutch provided on the input rotating member side with respect to the intermesh clutch are engaged, and the second power transmission path being established when a second friction clutch is engaged, the control apparatus comprising:
