Simulation of vehicle braking performance based on MATLAB

In order to better understand the vehicle braking performance, MATLAB software is used to calculate the vehicle braking performance. The relationship among ground braking force, braking force and adhesion force in the distribution of front and rear braking force is established, and the relationship diagram of F-Line group and R-line group is made. Using MATLAB software to simulate the steam performance, including the simulation of the ideal dynamic relationship between the front and rear brakes when braking, the simulation of the normal reaction force of the front and rear wheels when braking, the β curve and I curve when braking, the braking f line group and R line group. It is found that the normal reaction force of the front and rear wheels changes greatly when the braking strength or adhesion coefficient changes. When the acceleration is 0.6, the normal reaction force of the front wheel increases by 52.9%, while that of the rear wheel decreases by 31.1%. Line and І curve (full load) intersect point B, and the value of adhesion coefficient is 0.72.
