Control Method of Vehicle Directional Stability for Automobile Anti-lock Braking System
摘要
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.关键词
