PROBLEM TO BE SOLVED: To provide a vehicle driving force distribution control system for inhibiting heat generation of a switching element at a lower cost. SOLUTION: In the vehicle driving force distribution control system 90, the duty ratio of the pulse voltage generated as an FET71 is driven is lowered when an engine 10 is stopped, and the current running in the FET71 is reduced, and therefore, the quantity of heat generation of the FET71 is controlled. Accordingly, the heat generation of the FET can be inhibited at a low cost without upgrading the specification of the FET or adding a new cooling means as before. COPYRIGHT: (C)2004,JPO
