Outline
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.
