Research on test and evaluation technology of speed assist system
Most of the traditional traffic accidents are caused by human factors. Among them, overspeed driving is one of the main causes of serious traffic accidents. Based on the analysis of CIDAS accident data, this paper counted the speed limit of the road section when the speeding accident occurred, and elaborated the test scenarios and test methods of the speed limit information function and speed limit warning function of the speed assist system in the 2021 version of C-NCAP. At the same time, the limitations of the traditional speed limit warning system are analyzed, and the technical route and solution of the current speed assist system for passenger cars are introduced. Finally, three representative models are selected to verify the test scheme, and the test results are simply analyzed.
