摘要
随着科学技术的进步和人们物质生活水平的提高,人类社会对汽车的安全性,特别是制动安全性能提出了越来越高的要求。汽车防抱死制动系统是一种在制动时能够自动调节车轮制动力,防止车轮抱死以取得最佳制动效果的制动系统。该系统能够有效的缩短制动距离、提高制动时的方向稳定性,对汽车的行驶安全具有重要的意义。
车辆的制动系统性能是其重要性能之一,它直接关系到交通的安全。重大交通事故的发生,往往与制动距离过长,紧急制动时车轮抱死发生侧滑、甩尾、失去方向稳定性等情况有关。防抱死制动系统是一种在制动时能自动调节制动管路压力,使车轮不致抱死,以提高汽车行驶稳定性和制动安全性的自动调节系统。防抱死制动系统能够提高车辆安全性,具有明显的社会效益和经济效益。

ABSTRACT
With the development of science and technology and the improvement of the people's standard of living, human's requirement of the vehicle security e higher and higher, especially the braking security. Anti-lock braking system (ABS) is a kind of device, which can regulate the wheel's braking force automatically, prevent the wheels from locking and acquire the best effect during braking. This device is significant to steering safety.
The brake system performance is one of the vehicle's main function. It directly has a bearing on the traffic safety, the serious accidents always relate to the too long brake distance, wheel brake with emergency brake and then led to sideslip, swing or lose direction stability. Anti-Braking lock System can automatically adjust brake line pressure when the brake happens, and lead no wheel braking lock, it is an automatic regulation system which can improve the vehicle running stability and its brake safety. Anti-Braking lock System can improve the vehicle safety and it has obvious social benefits and economic benefits.
Keywords: Brakes;Brake Performance ;Anti-lock Braking system
