<P>PROBLEM TO BE SOLVED: To provide a driving force distribution control device capable of surely detecting disconnection abnormality, without erroneously detecting as the disconnection abnormality. <P>SOLUTION: A microcomputer 30 determines that an induction load circuit is abnormal when a difference between a test current of a predetermined value 1 output from a test current control means and an electric current value detected from an electric current detecting means is a predetermined value 2 or more. An abnormality determining means of the induction load circuit has an abnormality determination starting time for starting an abnormality determination and an abnormality determination executing time for determining abnormality, and lengthens the abnormality determination starting time, and shortens the abnormality determination executing time, when voltage of a battery is a predetermined value 3 or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
