Embodiment Construction
[0079] see Figure 1 to Figure 3 Shown:
[0080] The adaptive dynamic sliding mode self-driving vehicle path tracking control method considering input saturation provided by the present invention comprises the following steps:
[0081] Step 1. Establish an integrated path tracking model that considers both kinematics and two-degree-of-freedom vehicle dynamics.
[0082] Such as figure 1 The vehicle kinematics-based path-following error model shown is as follows:
[0083]
[0084] where e y is the distance between the center of mass of the vehicle and the corresponding point on the desired path on the y-axis of the vehicle center of mass coordinate system; v x is the longitudinal velocity of the vehicle; v y is the lateral speed of the vehicle; is the difference between the heading angle of the vehicle and the corresponding point on the desired path; ρ is the curvature of the corresponding point on the desired path; r is the yaw rate of the vehicle;
[0085] The dynam...
