Abstract: To improve the accuracy and scene coverage of the telematics BOX (T-BOX) protocol conformance testing in the internet of vehicle, and to reduce the potential safety risks of road extreme condition testing on actual vehicles, this article proposes an automatic testing system and method based on the laboratory virtual simulation environment. By calling custom test scripts through the automatic management and execution unit, simulating navigation satellite positioning signals and various working conditions of on-board bus communication scenarios in real vehicles, constructing multiple typical electromagnetic wave transmission channel models and abnormal faults, real-time analyzing and processing of communication data between on-board T-BOX and virtual cloud platforms, automatically judging test results and generating reports. This method can automatically establish a closed-loop test link under the premise of improving test accuracy, coverage and safety, effectively shortening the product development testing cycle.
