摘 要:时间如一个始终滚动行进的巨大车轮,推动人类社会不断向前发展。从信息时代到来以后,人们就以前所未有的热情投入到如何让生活更快速便捷,让世界成为一个真正的地球村。与此相应的是,汽车运动性能的不断改进,如何在保证足够安全的前提下更快,是每一个汽车公司不变的追求。如今,汽车的制动功能越来越成为衡量车辆性能的关键因素,一辆性能较高的汽车应该能做到在汽车制动的时候,相关系统能及时做出配合,使汽车安全、快速、稳定的停下来。一辆汽车能否做到精准制动,是关乎着驾驶员和乘车人员,以及道路上其他人性命的大问题,因而如何真正实现汽车制动优化也就显得格外重要。

Abstract: Time is like a huge wheel that always rolls forward, pushing human society forward. Since the advent of the information age, people have invested in how to make life faster and more convenient, and make the world a true global village. Correspondingly, the continuous improvement of the sports performance of the car, how to ensure the safety is safe enough, is the constant pursuit of every car company. Nowadays, the braking function of the car is becoming a key factor to measure the performance of the vehicle. A car with higher performance should be able to cooperate in time to make the car safe and fast when the car is braked. Stable stop. Whether a car can be accurately braked is a big issue for the driver and the passengers, as well as the lives of other people on the road. Therefore, how to truly realize the optimization of the car brake is particularly important.

引言
對人民生命财产的安全而言极为重要的制动系统目前却面临着非常严重的问题,主要原因在于轮胎在刹车时的摩擦力呈现非线性关系,并不是一个可控性很强的线性关系,这也就直接导致制动系统会在刹车时有时间延迟。在关键时刻,这种延迟会出现非常严重的后果,严重时甚至会发生车轮抱死的危险情况。而在路面情况不佳的时候,现有的制动系统因为无法改变的制动参数,在刹车时也会有很多问题。如何在路面较滑,摩擦力较小的情况下安全制动,是一个亟需解决的问题。
1 摩擦力非线性是主要缺陷
就中国目前的情况来看,汽车大多是以磁振式或者机械式ABS系统来制动的,在车速不快、路面情况并比较好、没有意外发生的情况下这种制动系统还是比较能保证车辆安全刹车的。……
