摘要：The 4-wheel steering system or the all-wheel steering system (4WS - Four Wheel Steering) can control all wheels on the car, increasing the vehicle's stability at high speeds and reducing the steering angle at high speeds. low speed. The 4WS system was born in the 80s, equipped on Honda Preludes in the late 1980s and early 1990s. The paper has built a kinematic relationship between the rotation angle of the 4WS guide wheels with the scaling factor k. Based on the built mathematical model, the author uses MATLAB/Simulink software to simulate the rotational dynamics of a car with a set of parameters of a specific vehicle. Perform the simulation of the rotation trajectory with different cases when changing the lateral stiffness of the tire. The author has built the relationship between the angle of rotation of the rear guide wheel compared to the front according to the speed through an available data map.
