摘要
A control device for controlling the running behavior of a four wheeled vehicle has a mathematical tire model of each wheel defining a relationship between longitudinal and lateral forces vs. slip ratio, synthesizes the mathematical tire model at zero slip and a control input from an outside running behavior controller such as a spin controller or a driftout controller to generate nominal values of longitudinal force, lateral force and yaw moment of the vehicle body, and controls the slip ratio of the wheels through cyclic adjustment so as to approach the differences between the nominal values and the actual values in the longitudinal force, lateral force and yaw moment of the vehicle body to the corresponding differences of those parameters due to differentiation thereof by the slip ratio based upon the mathematical tire model.
