PROBLEM TO BE SOLVED: To solve a problem wherein, although when an oil temperature of a coupling for transmitting power from an engine to wheels is in a low region, a control to suppress dragging torque generated at startup can be performed, when the ignition is turned ON in an abnormal state where the oil temperature is in a high region due to failure of an oil temperature sensor for detecting the oil temperature of the coupling, generation of dragging torque at startup can not be suppressed during a period from a startup after ignition ON until a failure detection is established as a determination result. SOLUTION: In determination of a four-wheel drive control, when the oil temperature of the coupling is higher than that of a transmission 11b, this control device determines that the oil temperature of the coupling is abnormal and uses the oil temperature of the transmission as a determined temperature.
