纯电动汽车整车控制器设计

摘要：当今世界由于环境问题和能源问题日益突出，使用电动汽车已经成为了趋势，电动车行业轮毂电机的使用已经非常广泛，但是电动汽车控制器的研发和使用尚未完善，本课题设计内就是以轮毂电机为动力的电动汽车整车控制器。

本课题对纯电动汽车控制系统分析和研究，对整车控制器输入输出信号的类型和功能来明确整车控制器的设计要求及控制器的设计要求本课题首先选定MC9S08DZ60芯片为纯电动汽车控制器,使用软件Protl99SE对纯电动汽车的整车控制器的硬件进行设计。然后结合分层设计思路和模块化设计思路，对纯电动汽车的整车控制器的软件架构、软件主程序进行构思设计，实现了纯电动汽车整车控制器各模块的功能和作用。

Design of vehicle controller for electric vehicle

Abstract：Due to the increasingly prominent environmental problems and energy problems, the use of electric vehicles has become a trend, the use of electric vehicle hub motor is very extensive, but the development and use of electric vehicle controller is not perfect, this paper design is a wheel motor as the power of electric vehicle controller. Through the analysis and research of the control system of pure electric vehicle, combined with the type and function of the vehicle controller input and output signal, the requirements of the pure electric vehicle controller design, determine the pure electric vehicle controller design. This paper first selects mc9s08dz60 chip as pure electric vehicle controller, using software protl99se to design the hardware of the vehicle controller of pure electric vehicle. Then combined with the layered design idea and modular design idea, the software architecture and software main program of pure electric vehicle controller are designed, the function and function of each module of pure electric vehicle controller.

Key words: pure electric; Protl99se; Wheel hub motors; Controller
