<p>PROBLEM TO BE SOLVED: To shorten time required from request of formation of a parking lock state to formation of the parking lock state.SOLUTION: When oil temperature Toil of a hydraulic oil is equal to or less than a threshold value Toref (S120), and stop of a vehicle is predicted while travelling (S130), by execution of restricted discharge processing in which a magnetic lock device is turned on and an on-off solenoid valve is turned off (S100, S140), discharge of the hydraulic oil in an oil chamber is started while the movement of a piston rod is restricted by the magnetic lock device. Then, when the vehicle stops and a shift position is changed to a parking position, the restriction of the piston rod is released by turning off the magnetic lock device.</p> |
