摘　　要：基于dSPACE软硬件,应用matlab/simulink系统建模方法,搭建了车辆起步控制的硬件在回路仿真平台;针对车辆起步控制系统存在的非线性、时变、多参数等特性,提出了对离合器和油门进行协调控制的分级模糊控制方法;利用推理法编写了单片机的模糊控制程序;基于上述平台,详细调整了各级模糊控制规则,并进行了起步控制的硬件在回路仿真实验;结果表明,该方法能够满足实时性要求,并具有良好的控制效果。A hardware-in-the-loop simulation pla（form of vehicle starting control system was established by utilizing system modeling method of matlab/simulink and environment of dSPACE software and hardware. Contraposing the characteristics of non-linearity, time-varying and multi-parameter existing in the vehicle starting control system, a hierarchical fuzzy control strategy was designed to conduct coordinate control of the clutch and throttle. A fuzzy control program for single-chip was written via logic deduction method. Based on the platform above, all the fuzzy control rules were adjusted and the hardware-in-the-loop simulation experiment was conducted. Result indicates that the strategy can satisfy the requirement of real-time performance with a good effect achieved meanwhile.
