Abstract:
1. A vehicle motion control device for a vehicle having wheels, the vehicle motion control device, comprising: a using friction circle computing unit for computing a size of a using friction circle in each of the wheels by multiplying a size of an each wheel friction circle indicating a maximum generating force in each wheel tire by a previously computed each wheel using percentage; an each wheel generating force computing unit for computing the each wheel tire generating force and the each wheel using percentage indicating a rate with respect to an upper limit value of a μ-using efficiency in each of the wheels, on the basis of a target vehicle body force and moment indicating a target vehicle body longitudinal force, a target vehicle body transverse force and a target yaw moment, and the sizes of the using friction circles computed by the using friction circle computing means; and a control unit for controlling a vehicle motion on the basis of the computed each wheel tire generating force, wherein the each wheel using percentage is a ratio of the μ-using efficiency in each of the wheels with respect to an upper limit of the μ-using efficiency, and the each wheel using percentage is: i) included as a parameter for computing the each wheel tire generating force, and ii) is determined repeatedly for each of the wheels, and the each wheel generating force computing unit comprises:
