Abstract:
1. A power transfer mechanism control device controlling a power transfer mechanism which is mounted on a vehicle including an automatically stoppable and automatically startable internal combustion engine and which transfers power from the internal combustion engine to an axle side via a friction engagement element actuated by a fluid pressure from either of a first fluid pressure actuator driven by the power from the internal combustion engine and a second fluid pressure actuator driven by a fluid pressure source different from a fluid pressure source for the first fluid pressure actuator, wherein in the case where the internal combustion engine which has been automatically stopped is to be automatically started, the second fluid pressure actuator is controlled such that, before complete combustion occurs in the internal combustion engine, the friction engagement element stands by in a low-pressure state in which a fluid pressure is lower than a fluid pressure at which torque is transferred, and the first fluid pressure actuator is controlled such that the friction engagement element transfers the torque at predetermined timing after the complete combustion occurs in the internal combustion engine.
