本发明涉及汽车故障诊断技术领域，尤其是一种基于OBD汽车故障诊断防作弊的系统。The invention relates to the technical field of automobile fault diagnosis, in particular to an OBD-based automobile fault diagnosis anti-cheating system.
背景技术Background technique
机动车是大气污染物的主要来源。特别是重型柴油车一直是机动车尾气污染物排放控制的重点和难点，一方面是年检和路检主要测试烟度排放，而NOx作为柴油车排放的另一重要污染物未得到有效的测试和监管，另一方面缺乏有效的排放快速检测手段。相比于年检、路检等传统检测手段，OBD具有排放检测项目全、速度快的特点，被行业内认为是最基本、最低成本、最有效的排放检测工具。Motor vehicles are a major source of air pollutants. In particular, heavy-duty diesel vehicles have always been the key and difficult point in the control of motor vehicle exhaust emissions. On the one hand, annual inspections and road inspections mainly test smoke emissions, while NOx, another important pollutant emitted by diesel vehicles, has not been effectively tested and On the other hand, there is a lack of effective rapid detection methods for emissions. Compared with traditional detection methods such as annual inspection and road inspection, OBD has the characteristics of complete emission detection items and fast speed, and is considered by the industry to be the most basic, lowest cost, and most effective emission detection tool.
某权威机构对70辆多个不同厂家的国4重型车进行了OBD检查，结果显示：故障指示灯MIL不能点亮；车辆存在故障码，但MIL灯没点亮；车辆DCU没有实时监测后处理系统；车辆后处理系统被拆除等等情况。同时除了上述的初级乱象，还发现车辆还存在其他高级乱象：屏蔽OBD功能，OBD起不到排放超标限扭作用；排放限值放大数倍，控制逻辑不变，排放限值数倍于国标；尾气后处理模拟器后处系统不能正常工作，通过模拟的方式骗过OBD系统；还有车辆内置作弊软件自动识别车辆是否正在被检测，被检测是符合排放标准，没有被检测时超标。An authoritative organization conducted OBD inspections on more than 70 national 4 heavy-duty vehicles from different manufacturers, and the results showed that: the fault indicator light MIL cannot be lit; the vehicle has a fault code, but the MIL light is not lit; the vehicle DCU does not have real-time monitoring and post-processing systems; removal of vehicle aftertreatment systems, etc. At the same time, in addition to the above-mentioned primary chaos, it is also found that there are other high-level chaos in the vehicle: the OBD function is blocked, and the OBD cannot play the role of limiting torque when the emission exceeds the standard; the emission limit is enlarged several times, the control logic remains unchanged, and the emission limit is several times higher than National standard; the rear system of the exhaust after-treatment simulator does not work normally, and the OBD system is deceived by simulation; there is also a built-in cheating software in the vehicle to automatically identify whether the vehicle is being tested, and it meets the emission standards when it is detected, and exceeds the standard when it is not detected.
