Control Method of Vehicle Directional Stability for Automobile Anti-lock Braking System

摘要

摘要: 为了保持汽车紧急制动时的方向稳定性，提出了控制前轮制动轮缸压力差的控制方法.将防抱死制动系统的控制过程分为首次控制和常规控制，首次控制在保证车轮不抱死的情况下，利用前轴两侧轮速差辨识路面；常规控制根据辨识结果，在单一附着系数路面下采用前轮增压同步控制，后轮独立控制，在分离附着系数路面下采用前轮修正低选控制，后轮独立控制.根据国家标准规定试验方法和流程，在试车场进行了4种典型路面上的制动试验，试验过程中车辆的方向盘修正角在2 s内均小于30，远小于国家标准规定的120，表明了控制方法的有效性.

Abstract: In order to maintain vehicle directional stability during the emergency braking, a control method of controlling the brake wheel cylinder pressure difference between the front wheels was put forward. The control process of the anti-lock braking system (ABS) is divided into first control and conventional control. In the first control, the rotational speed difference between front wheels is used to identify the road condition provided that the front wheels are not locking. According to the identification result, the conventional control adopts the method of synchronous pressurization for the front wheels and independent control for the rear wheels on single cohesion coefficient roads,and adopts modified low selector control for front wheels and independent control for the rear wheels on split cohesion coefficient roads. In addition, according to the test methods and procedure specified by the national standards, braking tests were carried out on four typical roads in a test field. The steering correction angle of the vehicle during the tests was less than 30 within 2 s, much less than the 120 in national standards, which shows the effectiveness of the control method.
