| 摘 要： | 基于有限状态机(FSM)理论,在MATLAB/Simulink/Stateflow仿真环境下,建立了适合车辆底盘集成控制系统的CAN网络通信模型,分析了网络信息帧在最坏情况时的最大时滞.将该模型应用于7自由度车辆ABS控制模型,对比研究了控制器在3种典型单一路面和对接路面情况下,采用CAN网络通信时,信息的通信时滞及丢帧对ABS控制器控制车轮滑移率性能的影响,并记录了所有信息帧的通信时滞时间.仿真结果表明,在低附着系数路面上,通信时滞效应会加剧车轮滑移率控制的不稳定性,虽然存在丢帧现象,但控制器仍能够保证车辆制动的有效性.

| Abstract: | The Controller Area Network(CAN) communication simulation model of vehicle chassis integrated control system was established based on FSM theory in MATLAB/Simulink/Stateflow,and the maximum transmission time of the frame under the worst case scenario was analyzed.The network commutation model was applied on the vehicle of 7 degree of freedom for Anti-lock Braking System control models,and the effect of CAN message transmission delay on the slip ratio was investigated under the condition of three typical sin... |
