Abstract
A control device for a vehicle is provided. The control device includes an electronic control unit that is configured to: exert the torque of an input member on a fixed member and a rotating member such that the fixed member and the rotating member are separated from each other, when the thrust is exerted for making the engagement teeth mesh with each other; estimate an inclination angle of tooth surfaces based on a relative movement amount between the fixed member and the rotating member, and a relative rotational amount between the fixed member and the rotating member; estimate a frictional coefficient of the tooth surfaces based on the inclination angle; and control the thrust of the actuator according to the frictional coefficient.
