Abstract
A power transfer mechanism control device controlling a power transfer mechanism mounted on a vehicle which transfers power from an 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. When the internal combustion engine 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, 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.
