To address the issues of low efficiency, high cost, and insufficient data reliability in the on-road test method for dynamic monitoring of the On-Board Diagnostic (OBD) system of heavy commercial vehicles under the China VI emission standard (GB 17691—2018), a dynamic OBD torque and speed limitation verification system based on Hardware-in-the-Loop (HiL) and signal virtual injection technology is proposed. By constructing a collaborative test platform composed of a chassis dynamometer data acquisition device (K - BOX), a high-precision urea level simulator, a multi - protocol OBD diagnostic module, and automated test software, closed - loop verification of the torque and speed limitation strategies of the Engine Control Unit (ECU) under abnormal urea level conditions is achieved. Currently, this technology has been successfully applied to 3 models of light and heavy commercial vehicles of a certain vehicle manufacturer.

为解决在国六排放标准（GB 17691—2018）下，重型商用车车载自动诊断（OBD）系统动态监测实车测试方法效率低、成本高及数据可靠性不足的问题，提出了一种基于硬件在环（HIL）与信号虚拟注入技术的动态OBD限扭限速验证系统。通过构建由底盘测功机数据采集设备（K-BOX）、高精度尿素液位模拟器、多协议OBD诊断模块及自动化测试软件组成的协同测试平台，实现了对发动机控制单元（ECU）在尿素液位异常工况下扭矩与车速限制策略的闭环验证。目前该技术已成功应用于某主机厂3款轻重型商用车。
