| Abstract: | Focusing on the problem of installed Body ECU program updating, a design of ECU program updating based on self-defined CAN protocol is realized on Infineon XC2000 series MCU. Then the hardware and software composition of program updating system, approach of MCU Bootloader, and working process of the system are introduce. The experimental results show that the system can achieve the function of program updating online and effectively solve some problems in the process of ECU online updating. |
