摘要
为分析防抱死系统的不同控制方式对整车制动性能的影响,基于滑移率的智能权函数模糊防抱死控制思想建立防抱死系统数学模型.通过Matlab/Simulink模块,建立了采用不同ABS控制方式的整车系统模型.利用该模型针对特定的工况进行了整车制动性能的仿真,并给出了ABS的布置方式.结果表明:独立和高选控制的布置方式能够充分利用路面条件进行制动,但车辆的稳定性被破坏;而低选控制方式的制动效能不及上述两种布置方式,但能保证车辆有较好的制动稳定性.
In order to study the braking effect of ABS with different kinds of control rules, the intelligent weight function fuzzy control method of ABS based on the slipping coefficient is introduced to establish anti-lock braking system. The finished vehicle system with different control rules of ABS is established in Matlab/Simulink. The model is used to simulate vehicle＇s braking performance in special conditions, and the suggestion for arrangement of ABS is made. The result shows that the road condition can be fully applied to brake by both unattached controlling and high selecting controlling methods, but the stability of the car is lost ; the braking effect of the low selecting method is less, but the stability is gained.
