摘要
为解决电动汽车整车控制系统开发周期长和稳定性差的问题,设计了一款纯电动汽车整车控制系统来研究整车控制问题。该系统基于飞思卡尔S12处理器开发的ECMV2硬件模块,软件的底层驱动是以Code Warrior IDE for HCS12为开发环境创建软件工程,封装成Simulink的图形化模块,提供全部板载外设驱动程序库,并提供GUI界面以便于配置,使得基础软件和控制算法在同一个平台上搭建并验证,以及建立了整车各模块模型和控制策略。通过实车测试进行验证,结果表明,电机驱动扭矩峰值的时间差是1 s,车辆的加速过程相对稳定;电池电压也不会迅速下降,驾驶员的操作也很快得到响应。可见该系统控制器灵敏度高,电机响应迅速,车辆运行平稳。此系统与传统的开发形式相比,开发时间大大缩短,增强了整车控制器的稳定性和可靠性。
In order to solve the problem of long development cycle and poor stability of the whole vehicle control system,the whole vehicle control problem was studied by designing a whole vehicle control system of pure electric vehicle.The system was based on freescale S12 processor development ECMV2 hardware module and code warrior IDE for HCS12 was used as development low-level environment to create software engineering.A simulink graphical module was encapsulated and a driver library for all onboard peripherals was provided.The GUI interface was also built for easy configuration.Thus,the software and control algorithm based on the same platform was built and verified and the module of the vehicle model and control strategy was established.Results show that the time difference of the peak torque of the motor is 1 s.The acceleration process of vehicles is relatively stable.Battery voltage does not drop quickly and the operation of the driver is also quickly responded.It is concluded that the controller of this system is highly sensitive,the motor responds quickly and the vehicle runs smoothly.Compared with the traditional development form,the development time of this system is greatly shortened,and the stability and reliability of the whole vehicle controller are enhanced.
