【摘  要】針對排放相關(guān)的網(wǎng)絡(luò)故障碼確認需要兩個或更多個駕駛循環(huán)的問題，提出一種基于Vehicle Spy的半自動化測試方法，在省去復(fù)雜硬件測試系統(tǒng)設(shè)計，節(jié)約成本的同時，保證測試結(jié)果的準確性，為今后排放相關(guān)網(wǎng)絡(luò)故障碼的設(shè)計評價、問題分析和邏輯測試奠定基礎(chǔ)。

【關(guān)鍵詞】Vehicle Spy；排放相關(guān)；網(wǎng)絡(luò)故障碼；測試

【Abstract】Aiming at the problem that two or more driving cycles are required for emission-related network DTC confirmation，a semi-automated test method based on Vehicle Spy is proposed，which abandons complex hardware test system design，saves cost，and ensures the accuracy of test results. It lays a foundation for the design evaluation，problem analysis and logic testing of emission-related network DTC in the future.

【Key words】Vehicle Spy；emission-related；network DTC；test

1  引言

隨著汽車功能日益豐富，配置也多樣化，車載電控單元ECU的數(shù)量在不斷增多，各ECU之間通過總線的信息交互也越來越多。（剩余3414字）
