摘要
介绍了CCP协议的基本原理、通信方式以及用于ECU标定的各种工作模式,讨论了一种基于该协议的汽车电控单元标定系统的设计方法。实际应用结果表明,该标定系统可以有效地实现对多个汽车电控单元进行在线标定,并可以针对不同用户需求提供不同的定制功能,在汽车电子控制系统开发中将能得到较好的应用。
The principle and communication method of CCP protocol and the various working modes of ECU＇s calibration were introduced, and the design method of calibration system based on CPP protocol on automobile electronic control unit was discussed. The test results show that the calibration system can calibrate multiple ECUs of automobile system effectively and that different customized functions are available according to customer＇s requirements. Accordingly, the system can be well used in the development of the automobile electronic control unit.
