A microcomputer (32) of a driving force distribution control device (31) detects a maximum current value among values of an upper current (actual current flowing through a shunt resistor (41a) on a power supply side) acquired during a predetermined period, and determines that an overcurrent abnormality has occurred in the driving force distribution control device (31) when the maximum current value is equal to or larger than an abnormal current threshold value and a time, for which the maximum current value is equal to or larger than the abnormal current threshold value, is equal to or larger than an abnormality detection time. Then, the microcomputer (32) performs off control to turn off a relay (35), and notifies a driver of occurrence of the overcurrent abnormality using a notification unit (50). |
