A drive force control system for a vehicle having a pair of front wheels (WFR, WFL) and a pair of rear wheels (WRR, WRL), comprising: a distribution mechanism, which distributes power outputted from a prime mover to a right wheel (WFR, WRR) and to a left wheel (WFL, WRL) of any one of said pairs of front and rear wheels, and which changes a ratio to distribute the power to those right and left wheels (WFR, WRR, WFL, WRL) by engaging or disengaging an engagement mechanism (B1, CR, CL); at least two motors (ML, MR) arranged individually for a right and a left wheels of the other pair of wheels (WFR, WRR, WFL, WRL) to control drive forces for driving those right and left wheels (WFR, WRR, WFL, WRL) individually; characterized by: a means which calculates a deficiency of a difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said one of the pairs of wheels resulting from a delay in changing such a difference therebetween by actuating the engagement mechanism (B1, CR, CL); and a means which sets a difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said other pair of wheels, thereby compensating the calculated deficiency of the difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said one of the pairs of wheels resulting from a delay in changing such a difference therebetween. a distribution mechanism, which distributes power outputted from a prime mover to a right wheel (WFR, WRR) and to a left wheel (WFL, WRL) of any one of said pairs of front and rear wheels, and which changes a ratio to distribute the power to those right and left wheels (WFR, WRR, WFL, WRL) by engaging or disengaging an engagement mechanism (B1, CR, CL); at least two motors (ML, MR) arranged individually for a right and a left wheels of the other pair of wheels (WFR, WRR, WFL, WRL) to control drive forces for driving those right and left wheels (WFR, WRR, WFL, WRL) individually; characterized by: a means which calculates a deficiency of a difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said one of the pairs of wheels resulting from a delay in changing such a difference therebetween by actuating the engagement mechanism (B1, CR, CL); and a means which sets a difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said other pair of wheels, thereby compensating the calculated deficiency of the difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said one of the pairs of wheels resulting from a delay in changing such a difference therebetween. a means which calculates a deficiency of a difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said one of the pairs of wheels resulting from a delay in changing such a difference therebetween by actuating the engagement mechanism (B1, CR, CL); and a means which sets a difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said other pair of wheels, thereby compensating the calculated deficiency of the difference between the drive forces for driving the right and the left wheels (WFR, WRR, WFL, WRL) of said one of the pairs of wheels resulting from a delay in changing such a difference therebetween.
