Abstract
A movement state control apparatus for a wheeled vehicle capable of constantly maintaining the movement state of the vehicle in an optimal condition even if various kinds of parameters of the vehicle are changed. The control apparatus includes a yaw rate sensor for detecting a yaw rate as one of movement state variables of the vehicle, a microcomputer programmed to detect a lateral slip angle as one of the other movement state variables for determining a target yaw rate and a target lateral slip angle as a target movement state variable and to calculate a feedback rear wheel steering angle by multiplying a difference between the detected movement state variable and the target movement state variable with a feedback gain of a predetermined frequency characteristic for ensuring robust stability of the vehicle and robust control performance without any influences caused by a zero-point drift and high frequency noises of the yaw sensor.
