摘　　要：本文以无人驾驶车辆为研究背景,研究基于CCP协议的自动驾驶控制器MCU固件标定系统的设计和实现。整个系统包含以MCU为控制芯片的自动驾驶控制器、USBCAN数据采集卡、MCU固件标定上位机软件。自动驾驶控制器借助事先约定好CCP协议完成一些参数的标定,切换一些复杂的自动驾驶控制逻辑和策略,同时借助事先存储在MCU内的BootLoader引导程序实现自动驾驶控制器APP程序的更新。通过测试发现,此系统工作稳定,通讯数据完整可靠。In this paper,the design and implementation of MCU fi rmware calibration system based on CCP protocol is studied under the background of driverless vehicle.The system includes automatic driving controller with MCU as control chip,USB-can data acquisition card and MCU fi rmware calibration upper computer software.The automatic driving controller completes the calibration of some parameters and switches some complex automatic driving control logic and strategy with the help of CCP protocol.At the same time,the app program of automatic driving controller is updated by Bootloader boot program stored in MCU.Through the test,it is found that the system works stably and the communication data is complete and reliable.
