In a vehicle provided with a transmission that has a lock-up clutch that is directly couplable between drive sources and a drive shaft, the shock of switching between the drive sources is prevented from being transmitted. It is determined whether the drive source is to be switched, and when "YES" is determined, a lock-up clutch is disengaged or placed in a half-engaged state, and the shock due to switching of the drive source is prevented from being transmitted. Then, after it is confirmed that switching of the drive source is completed, the lock-up clutch is once again placed in the fully-engaged state.
