摘　　要：为了保证基于CAN总线ECU诊断功能的正确性和稳定性,在分析CAN总线诊断系统的基础上,提出了一种针对诊断功能的测试方法。根据CAN总线诊断协议ISO 15765,从黑盒测试的角度设计了测试方案和测试用例。最后以CANoe总线分析测试软件为基础搭建测试平台,完成了对ECU诊断功能的一致性测试。测试结果验证了此方法能有效地测试ECU诊断功能与诊断协议ISO 15765的一致性,表明此诊断测试方法可行。In order to ensure the correctness and stability of ECU diagnostic function based on CAN bus, on the basis of analysis of CAN bus diagnostic system, a test method for diagnostic function is proposed. According to CAN bus diagnostic protocol ISO 15765, test scheme and test cases are designed from the view of blackboxtesting. Finally,test platform based on CANoe Bus analysis testing software is built up, the consistency test of ECU diagnostic function is fulfilled. Test result verifies that the method can effectively test the consistency between the ECU diagnostic function and diagnostic protocol ISO 15765, and shows the diagnostic test method is feasible.
