Abstract
When an oil temperature Toil is equal to or lower than a threshold Toref, and when a vehicle is predicted to stop while traveling (a shift position is predicted to be operated to a parking position), restricted discharge processing is executed in which a magnetic lock device is turned ON and an on-off solenoid valve is turned OFF. Thus, discharge of hydraulic oil in an oil chamber is started while movement of a piston rod is restricted by the magnetic lock device. Then, when the vehicle stops and the shift position is changed to a parking position, the restriction on the movement of the piston rod is removed by turning OFF the magnetic lock device.
