Abstract
A vehicle motion control system is provided. In a first state requiring understeer suppressing control, a controller determines, based on a yaw rate deviation, a first control amount of an actuator selected so as to generate an inward turning moment a vehicle. In a second state requiring spin suppressing control, the controller determines, based on the sideways slip angular velocity, a second control amount of an actuator selected so as to generate an outward turning moment in the vehicle. When the first and second states are concurrent, the controller selects an actuator to be controlled by the larger of the absolute values of first and second cooperative control amounts, and determines a control amount of the selected actuator as the sum of the first and second cooperative control amounts. Accordingly, the understeer suppressing control and the spin suppressing control can be performed in parallel, improving control performance.
