摘要
随着现代汽车技术的快速发展,人们在注重汽车的舒适性、可靠性、经济性的同时,对汽车的安全性更是提出了最高的要求。事实证明ESP电子稳定程序可以有效地降低重大交通事故发生率,从而挽救许许多多人的生命,为进一步加强汽车的乘坐安全性,全球道路专家一致认为ESP应该成为每一辆车的标准配置。汽车电子稳定程序(Electronic Stablity Program,简称ESP)是由奔驰汽车公司首先应用在它的A级车上的。ESP实际上是一种牵引力控制系统,与其他牵引力控制系统比较,ESP不但控制驱动轮,而且可控制从动轮。如后轮驱动汽车常出现的转向过多情况,此时后轮失控而甩尾,ESP便会刹慢外侧的前轮来稳定车子;在转向过少时,为了校正循迹方向,ESP则会刹慢内后轮,从而校正行驶方向。本文介绍了汽车电子稳定系统 ESP的概念、结构组成、工作原理及发展趋势。

Abstract
With the rapid development of modern automotive technology, people focus on vehicle com
fort , reliability and economy at the same time , the safety of the car is made of the highest demands. ESP electronic stability program proved to be effective in reducing the incidence of major accidents , thereby saving the lives of many people , to further enhance the car 's ride safety experts agree that the world's roads each vehicle ESP should become the standard configuration . Automotive Electronic Stability Program (Electronic Stablity Program, referred to as ESP) was first applied by the Mercedes-Benz A-class in its car . ESP is actually a traction control system , traction control system compared with other , ESP not only control wheels , and can control the driven wheels . As often occurs in rear-wheel drive car oversteering situation , when the rear wheel drift out of control , ESP will slowly brake the outside front wheel to stabilize the car ; steering is too low, in order to correct tracking direction , ESP will brake slow rear wheel , thereby correcting the direction of travel. This paper introduces the concept of automotive electronic stability system ESP , structure , working principle and trends.
