Method of Determining Rear Wheel Steering Angle of Active Four Wheel Steering Device Using First Missing Transfer State Control Logic

摘要

The present invention relates to a method of determining the rear wheel steering angle of an active four-wheel steering apparatus using a first-order transfer control state control logic, which grasps the steering of the vehicle and the motion state of the vehicle, The steering angle of the front wheel and the speed of the vehicle traveling direction are used to determine the rear wheel steering angle. First, the steering angular velocity and the steering angular acceleration of the steering wheel are determined, and the steering angle and steering angle of the front wheel are determined. Then, the steering angle of the rear wheel is determined by the first-order angular- This determination method is linearly analyzed by controlling the nonlinear transient state and steep state change of the mechanical phenomenon, which is a natural phenomenon, by a formula, and is more easily controlled by the basic sensor only in the transient state.
