纯电动汽车整车控制器的设计

Design of vehicle controller for pure electric vehicles

纯电动汽车不仅仅是作为整车控制器的调控中心,同时也在整车控制器中起到核心作用。文章给出了纯电动汽车整车控制系统的基本结构,以及整车的工作方式,在此基础上提出了不同的工作方式下对应的各种控制策略。紧接着根据其控制策略设计了整车控制器的相关硬件电路,最后结合整车控制器的硬件电路和控制策略,完成了整车控制器的主程序和各个子程序的整体设计。

Pure electric vehicles are not only the control center of the vehicle controller, but also play a central role in the vehicle controller. In this paper, the basic structure of the whole vehicle control system of pure electric vehicle and the working mode of the whole vehicle are given. On this basis, various control strategies corresponding to different working modes are proposed. Then the hardware circuit of the whole vehicle controller is designed according to its control strategy. Finally, the hardware design and control strategy of the vehicle controller are combined to complete the overall design of the main program and the sub-programs of the vehicle controller.
