摘　　要：对DKC12地下自卸汽车ABS系统进行方案选择及设计,包括通道布置、轮速传感器选型、齿圈设计、新式ABS液压控制系统设计、二位二通高速开关电磁阀相关参数计算。完成基于80C196KB微控制器的ABS系统ECU硬件功能设计,包括单片机最小应用系统设计、单片机系统扩展设计、输入通道设计和输出通道设计。利用MATLAB/SIMULINK建立了以车轮滑移率为控制参数的ABS系统控制逻辑,确定出仿真系统各个模块计算的步长,设计出较为灵活的改变仿真参数设置的方法,以便于进行不同测试条件下不同车辆参数的仿真计算,利用ADAMS/SIMULINK对车辆动力学模型进行联合仿真分析,并与未带ABS系统时车辆制动过程进行对比。仿真结果表明,以车轮滑移率为控制参数的ABS系统模型可以在车辆制动过程中避免某个车轮提前抱死,从而提升了整车的安全性。The ABS system for the DKC12 Underground Dump Truck is determined and designed, including the design of the channels, the choice of the speed sensors, the design of the gear circles. Furthermore, the parameters of the 2/2 high-speed switch electromagnetism valve is calculated. The ECU hardware, based on 80C196KB MCU, used to sample and control, is designed, including the designs of the least application system, the system expand, the import channels and the export channels for the SCM. A reasonable ABS control logic is set up by using ADAMS/SIMULINK. The simulation step of the vehicle model is carefully studied. A flexible way to al- ter the parameters of the vehicle and the ABS control logic is introduced in order to calculate the changeable initial velocity of the truck the variable load and road conditions. Co-simulation of the truck mechanical model is conducted by use of the ADAMS/SIMULINK. The brake process of the vehicle with ABS is compared to the vehicle without ABS. The simulation analysis shows that this control logic could improve the security of the DKC12 Underground Dump Truck via anti-lock some wheels through the whole brake process.
