Abstract
When there is backlash in a rotation direction between a lock member at a lock position and a first rotary member, a rotational position of a target rotary member, the rotational position being detected in a locked state of a parking lock mechanism by a rotational position sensor, is defined as a detected rotational position, and a rotational position of the target rotary member in a case where it is assumed that there is not the backlash in the locked state of the parking lock mechanism is defined as a theoretical lock position, a control device executes torque direction determination processing that determines a wheel torque direction, on the basis of a direction of deviation of the detected rotational position from the theoretical lock position due to the backlash.
