【摘  要】針對(duì)排放相關(guān)的網(wǎng)絡(luò)故障碼確認(rèn)需要兩個(gè)或更多個(gè)駕駛循環(huán)的問(wèn)題，提出一種基于Vehicle Spy的半自動(dòng)化測(cè)試方法，在省去復(fù)雜硬件測(cè)試系統(tǒng)設(shè)計(jì)，節(jié)約成本的同時(shí)，保證測(cè)試結(jié)果的準(zhǔn)確性，為今后排放相關(guān)網(wǎng)絡(luò)故障碼的設(shè)計(jì)評(píng)價(jià)、問(wèn)題分析和邏輯測(cè)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(cè)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(chē)功能日益豐富，配置也多樣化，車(chē)載電控單元ECU的數(shù)量在不斷增多，各ECU之間通過(guò)總線(xiàn)的信息交互也越來(lái)越多。（剩余3414字）
