Abstract:
1. A driving force distribution control device for a vehicle for controlling engaging force of a coupling mechanism so as to change transmission torque, thereby distributing driving force, said device comprising: means for determining a mounting of a nonstandard-diameter tire; means for continuously changing a torque limiter which limits engaging force of said coupling mechanism, from a limiter value in an ordinary control state according to a driving state, to a limiter value in a specific control state at the time of determining the mounting of the nonstandard-diameter tire; means for controlling engaging force of said coupling mechanism so as to be kept below the limiter value of the torque limiter in every control state; and means for setting amount-of-change of the torque limiter per time increment at transition from the ordinary control state to the specific control state and amount-of-change of the torque limiter per time increment at recovery from the specific control state to the ordinary control state such that the latter is relatively larger than the former.
