基于Matlab／Simulink的汽车ABS建模与仿真

Modeling and Simulation of the Anti-lock Braking System of Automobiles Based on Matlab/Simulink

该文以单轮车辆为研究对象，建立整车数学模型、轮胎模型、制动器模型、液压系统模型和滑移率的计算模型。对所建立的汽车ABS数学模型进行仿真研究，得出仿真曲线。仿真结果表明，建立的ABS数学模型可靠，能达到较为理想的制动控制效果，验证了汽车ABS具有良好的制动性能和方向操纵性。

In the paper, a single-wheel vehicle is used as a research target to establish a mathematical model for an entire car and a tire model, a brake model, a hydraulic system model and a slip ratio calculation model. The established ABS mathematical model is simulated and researched and the simulation curve is obtained. The simulation result shows that the established models are reliable and can achieve desirable brake control effects and proves that the auto ABS is of excellent braking performance and manipulatory ability.
