Research on Vehicle Steering Characteristic Based on MATLAB

The steering characteristic of the vehicle were researched, the equations of motion and state of the vehicle model were built on the basis of the theoretical cornering movement. The motion simulation based on MATLAB analysis of two degrees of freedom and three degrees of freedom for the vehicle models under the cornering wheel angle step input was carried out. The change laws of steering sensitivity, yaw velocity, lateral acceleration, front and rear lateral forces, and sideslip angle with different speeds were studied. The results show that the simulation analysis provides the basis for the forecast of vehicle cornering performance.
