PROBLEM TO BE SOLVED: To restrict wear of a synchronizer.;SOLUTION: When the oil temperature of a front differential gear connected to a front output shaft of a transformer through a front propeller shaft is low (YES in S104), an ECU controls a current value of an actuator for moving a sleeve so as to raise the current value after concluding synchronization of a rear output shaft with the front output shaft of the transformer, and carries out a program including a step for switching from a two-wheel driving mode to a four-wheel driving mode (S106). The rear output shaft and the front output shaft are synchronized by a synchronizer abutting on the sleeve.;COPYRIGHT: (C)2008,JPO&INPIT
