ABS(Anti-Lock Brake System,简称ABS)系统在汽车上的应用也越来越广泛,但研究发现安装ABS的汽车在冰雪路面上制动时距离反而加长。因此,本文通过分析优化后ABS系统制动距离的可行性,提出了ABS系统的优化模型,并对机械模型进行设计及仿真研究,同时对电路控制部分进行改进,达到优化制动系统、提高汽车制动性能的目的。 ABS (Anti-Lock Brake System, ABS) system is also more and more widely used in automotive applications, but the study found that the installation of ABS car instead of braking on ice and snow the distance instead of longer. Therefore, by analyzing the feasibility of the optimized braking distance of the ABS system, this paper presents an optimization model of the ABS system, studies the design and simulation of the mechanical model, improves the control part of the circuit to optimize the braking system, The purpose of braking performance.
