Abstract

When starting automatic pulling-in control, an electronic control unit calculates a temperature increase amount ΔTi of a motor caused by the execution of the automatic pulling-in control and a temperature increase amount ΔTo of the motor caused by the execution of automatic pulling-out control. Based on the current temperature of the motor, the temperature increase amount ΔTi, and the temperature increase amount ΔTo, the electronic control unit obtains a predicted temperature of the motor of a case in which the automatic pulling-out control is executed subsequent to the automatic pulling-in control. When the predicted temperature is lower than an allowable upper limit, starting of the automatic pulling-in control is permitted. When the predicted temperature is higher than or equal to the allowable upper limit, starting of the automatic pulling-in control is prohibited.
