摘要
在分析工程实际需求和已有在线更新电控单元应用程序方案的基础上,提出了一种新的基于CCP(CANCalibrationProtocol)协议的在线更新电控单元程序的软件机制。该软件机制充分利用了当前车用电控单元中广泛采用的CAN总线网络,为电控单元应用程序调试和测试提供了一种快速方便的程序下载方案。给出了该方案实现过程中两个难点问题的解决方法。
On the basis of the analysing,the actual engineering requirements and the available solution of online updating ECU application software,one new CCP-based online updating ECU program software mechanism is presented.The software mechanism makes best of the widely used CAN bus network in current vehicles,and it provides a fast and conve nient program downloading solution for ECU software debugging and testing.The solutions of two difficulties in the mechanism's implementation are also explained.
