Abstract
A power transfer mechanism control device that controls a power transfer mechanism which is mounted on a vehicle including an automatically stoppable and automatically startable motor and which transfers power from the motor to an axle side via a friction engagement element actuated by a fluid pressure from a fluid pressure actuator, wherein during neutral control performed while the motor is in operation, a neutral control amount, which is a control amount for causing the friction engagement element to stand by in a neutral state with pressure lower than a complete engagement pressure, is set on the basis of a power transfer state of the power transfer mechanism to control the fluid pressure actuator, and learned, and while the motor is automatically stopped, the fluid pressure actuator is controlled using the learned neutral control amount such that the friction engagement element stands by in the neutral state.
