摘要: 针对大功率感性车身电器启停期间的瞬间电流过大的问题,建立一种基于软启动技术的车身控制器。该控制器充分利用单片机(MCU)的控制资源和大规模可编程逻辑门阵列(FPGA)的可扩展优势,实现了对多路开关量信号的快速采样和脉冲宽度调试信号(PWM)信号的输出。在控制软件设计方面,采用结构化模块设计方法,有效地完成了车身控制器的功能和要求。测试结果表明,该系统有效地改善了整车电磁干扰(EMI)并实现了对大功率感性负载软启动,减少了负载的瞬间启动电流的40%以上,同时完成了无人驾驶电动车的车身控制所需的功能。

Abstract: To solve the instantaneous overcurrent of the large power inductive load, a body control system based on soft start was established. The abundant peripherals of Micro Control Unit (MCU) and the scalability of Field Programmable Gate Array (FPGA) were fully utilized to implement the rapid sampling of the multiplex switching signals and the output control of the Pulse Width Modulation (PWM) signals. In the software, the program was designed by the modular, which completed the task and met the need of the car. At last, the test shows the Electromagnetic Interference (EMI) on the vehicle is reduced, soft start of the large inductive equipment is realized, and the instantaneous overcurrent of the load is reduced by 40%, so the body control system can be applied with the unmanned vehicle's control

Key words: body control system, Micro Control Unit (MCU), Field Programmable Gate Array (FPGA), Pulse Width Modulation (PWM), soft start
