发明名称 Four-wheel drive vehicle
摘要 A vehicle includes a sensor sensing external temperature, a 2WD/4WD switch operated to input an instruction to switch a two-wheel drive state and a four-wheel drive state, a transfer switching mechanical power transfer for the two-wheel drive state and that for the four-wheel drive state, an actuator actuating the transfer, and an ECU controlling the actuator. The ECU determines from a value detected by the sensor a current supplied to the actuator. Preferably, the transfer includes a synchronizer mechanism driven by power generated by the actuator to transfer a drive shaft's rotation to a driven shaft and engage the shafts together when they achieve synchronous rotation.
