Abstract
A control of a vehicle motion control deviceis as follows during an oversteer restraining control. Specifically, when tire inflation pressure is appropriate, the device sets braking force exerted on each of front and rear wheels at the outer side of the turning direction so as to be reference braking forces Ffand Fr, that are generated when an absolute value of a lateral acceleration deviation ΔGy is not less than a reference value aand that respectively increase up to an upper limit value ff and upper limit value fr in accordance with the increase in the absolute value of the lateral acceleration deviation ΔGy. On the other hand, when a tire inflation pressure of one of the front and rear wheels at the outer side of the turning direction is lowered, the device sets the braking force, such that the braking force starts to be generated from when the absolute value of the lateral acceleration deviation ΔGy is smaller than the reference value aby an amount in accordance with the reduction in the tire inflation pressure and that the upper limit value of the braking force with respect to the wheel whose tire inflation pressure is lowered is decreased by an amount in accordance with the reduction in the tire inflation pressure and that the upper limit value of the braking force with respect to the wheel that is not the wheel whose tire inflation pressure is lowered is increased by an amount in accordance with the reduction in the tire inflation pressure.
