DRIVE FORCE ALLOCATION CONTROL APPARATUS

A driving force distribution control device controls an inductive load circuit to adjust a ratio of driving forces transmitted from a driving source to a plurality of wheels via a driving force transmitting system. The driving force distribution control device counts a number of tests performed by applying a test current to the inductive load circuit; determines that a disconnecting abnormality occurs in an electric load including the inductive load circuit if a difference between a value of the test current and a value of current flowing in the inductive load circuit is greater than a current difference threshold value; and determines that the disconnecting abnormality is definitive if the number of tests is equal to a threshold value or more, and also if the number of determinations of the disconnecting abnormality is equal to a predetermined threshold value or more.
