Abstract
An ECU executes a program including the step of controlling the current value of an actuator that moves a sleeve by increasing the current value subsequent to complete synchronization between a rear output shaft and a front output shaft of a transfer when the oil temperature of a front differential connected to the front output shaft of the transfer via a front propeller shaft is low to switch from a two-wheel drive state to a four-wheel drive state. The rear output shaft and front output shaft are brought into synchronization by a synchronizer abutting against the sleeve.
