汽车ABS制动过程车速的一种测量方法

A measurement to the speed of vehicle with ABS during braking

汽车ABS是改善汽车主动安全性的重要装置,通过调节制动力,使汽车获得良好的制动效能并保持较高方向操纵稳定性。车轮滑移率是制动力调节的主要依据,车速是其不可缺少的参数。本文提出一种利用对加速度传感器测得的加速度积分获得制动过程车速的方法,并经试验证实其可行性。

Anti-lock braking system is an important device to improve the active safety of vehicles .By regulating brake force vehicles obtain good brake efficiency and control ability .Regulating brake force is based on the slip ratio so the speed of vehicle is an indispensable parameter. The paper put forward a measurement to the speed of vehicle with ABS during braking by integral of acceleration and validated it by a test.
