| 中文摘要: |
| 针对汽车制动的特点，分析了汽车制动过程的几个主要阶段，探讨了影响汽车制动的主要因素，建立了轮胎旋转动力学模型和半车制动模型，提出了滑模变结构的防抱死制动系统，并采用基于指数趋近律的方法进行制动。仿真实验表明，能够提高汽车的制动性能、缩短抱死刹车距离，有效抑制抖动现象。 |
| 英文摘要: |
| According to the characteristics of the vehicle brake, the main stages of automobile brake are analyzed, the main factors of affecting vehicle brake are discussed, the dynamic model of tire rotation and half vehicle braking model are established. An anti lock braking system with sliding mode variable structure is proposed, and a braking law based on exponential approach law is adopted. The simulation results show that the method can improve the braking performance of the vehicle, shorten the braking distance and effectively suppress the jitter phenomenon. |
