摘　　要：作为电TCU的通信模块,CAN模块是其重要组成部分之一,对TCU控制的性能以及实时性有着至关重要的影响。基于微控制器MC9S12系列单片机和英飞凌公司的CAN驱动芯片TLE6250,设计了TCU中CAN通信模块的硬件电路和软件。并通过实车测试其通信验证了此设计方案的可行性。结果显示,本设计方案能满足TCU的各种通信要求。As one of an important part of TCU＇s communication module, CAN module has a critical impact on TCU＇s control and real-time performance. Based on micro-controller MC9S12 family microcontroller and the Infineon＇s CAN driver chip TLE6250, designed the CAN communication module hardware circuit and software for TCU. And testing its communication through the real vehicle, which verified the feasibility of this design. The results show that this design can meet variety communication requirements of TCU.
