Parking lock control device for vehicle and control method

摘要

In a parking lock control device of a vehicle of the present invention, when a parking lock activation command is outputted, either one of parking lock mechanisms is activated. In this state, a movement of the vehicle is estimated or detected, and when the vehicle movement is a predetermined amount or more, the parking lock control device generates a torque that suppresses the vehicle movement by the motor connected to the other parking lock mechanism. Power consumption associated with the parking lock is then suppressed.
