<p>PURPOSE:To effectively restrain spin of a vehicle in the condition at turning limit by constituting the device so that information of driving force decreasing operation is monitored on the control means side for distribution of driving force to front and rear wheels, and a changeable driving force distribution clutch is controlled to be released at driving force decreasing operation. CONSTITUTION:At operation of a driving force control means (b), a changeable driving force distribution clutch (c) is controlled to intend to be released in a control means (d) for distribution of driving force to front and rear wheels. Hereby, when decreasing control of engine driving force begins in the running condition at turning limit of a vehicle, on the clutch coupled driving wheel side, the driving force before clutch release is actuated as it is due to inertia for a little while directly after the clutch release, and lateral force to a tire is hardly changed. Meanwhile, on the engine coupled driving wheel side, lateral force to a tire is increased accompanied with decrease of the driving force due to direct effect of decrease of engine driving force. Hereby, for a little while directly after release of the clutch (c), moment around the center of gravity of the vehicle is generated in the reverse direction against the turning direction.</p> |
