摘要
为了有效验证整车ABS控制器实车匹配前的控制效果,通过Carsim动力学仿真软件建立整车的参数化模型,在Matlab/Simulink中搭建了两种ABS控制策略,一种是自主开发的基于滑移率为主要控制目标、以车轮角速度为辅助控制目标的逻辑门限值ABS控制策略,另一种是实际当中常用的PID控制策略;将Carsim与Matlab/Simulink进行联合仿真,选取了对开路面紧急制动时仿真试验,逻辑门限值ABS控制策略明显优于PID控制策略;最后,选取同样工况进行硬件在环试验,结果证明了ABS逻辑门限值控制策略能够在实际控制过程中保证良好的制动效能及制动方向稳定性。
The effective method is put forward to verify vehicle ABS controller real vehicle matching effect.The parameterized vehicle model is established in Carsim dynamics simulation software.Two kinds of ABS control strategy can be established in the Matlab/Simulink software.One is ABS logic threshold control strategy which mainly controls slip rate and assistantly controls wheel angular velocity,another is ABS PID control strategy.Logic threshold is obviously superior to PID in the control effect by Carsim and Matlab/Simulink co-simulation test based on emergency braking under typical split road.Finally the logic threshold actual control effect that can be validated by hardware-in-loop test station based on the same working condition.The experiment may prove the logic threshold effective conrrol effect of good braking performance and braking direction stability.
