PROBLEM TO BE SOLVED: To properly execute differential limiting force control superior in straightly advancing stability in response to a vehicle speed, in various vehicles different in vehicle specifications. SOLUTION: Assuming that a yaw rateγof a vehicle is expressed by an expression (4)γ= Gy×äV/(1 +AV<SP>2</SP>)} determined based on various vehicle specifications, a correction factor (k) is calculated in response to an actual vehicle speed V according to an expression (2)k = V/(1 + AV<SP>2</SP>) set based on its expression (4). Differential limiting force Mo is determined by multiplying its correction factor (k) and predetermined reference differential limiting force Mv, and differential limiting force of a differential limiting clutch 34 is controlled based on this differential limiting force Mo. Thus, the differential limiting force control superior in straightly advancing stability is properly executed in response to the vehicle speed V in the various vehicles different in the vehicle specifications.
