摘要
论文设计了一种基于CAN总线的车载ECU控制器程序刷写系统,并对其软硬件框架,核心思路和算法实现进行了论述。基于英飞凌XC2000系列单片机,进行了实际系统的设计,并对其性能进行了验证。实际验证结果表明,该刷写方式能有效的提高车载ECU刷写的可靠性和速度,并提供了车载ECU再次进行刷写升级的可能性。
In this paper,a CAN bus-based ECU program burning system is designed,and its hardware and software framework,core ideas and algorithm implementation are discussed. Afterwards,based on the Infineon XC2000 series microcontrollers,the actual system design was carried out and its performance was verified. The actual verification results show that the program burning method can effectively improve the reliability and speed of the on-board ECU＇s burning,and provides the possibility for the vehicle-mounted ECU to update again.
