PROBLEM TO BE SOLVED: To improve reliability and productivity of a power distribution control device and to enlarge a loaded object range of the device related to a car type, by securing independency of the power distribution control device. SOLUTION: In a step 210, a value of a quick brake control flag F (1: quick brake control mode, and 0: normal control mode) is discriminated, and a 'quick brake discriminating routine' is called and executed for F=0. In the quick brake discriminating routine, the control device discriminates a quick brake state of a vehicle by itself, and determines whether movement to the quick brake control mode is performed. The process proceeds to a step 240 when a return code RC is 0 (normal state), or to a step 245 when the RC is 1 (quick brake state). It is estimated that an ABS operates when the quick brake state is detected continuously T1 times. When F is 1, an engaging degree r of a coupling is 0 and rear wheels are not driven, so that interference phenomenon between ABS control and 4WD control does not occur in the quick brake control mode.
