Design of Universal Detection System for Automobile Combination Dashboard

摘要

The detection of automotive combination dashboard is usually implemented by adopting the specific detection system matched with models, and automotive combination dashboard of different models requires different detection systems. A universal automatic detection system is designed in this paper, which can detect different kinds and models of automotive combination dashboard. First, standard detection signal generated by the electronic control unit is added to every corresponding position of dashboard, second, cameras film the corresponding images of dashboard in the standard signal excitation, last, the image is sent to the host computer for image processing to get output data of dashboard. This system detects results of automotive combination dashboard with the maximum relative error less than 2.5%, which meets the specified accuracy requirements in the automotive industrial standard QC/T727-2007 "Instruments for Motor Vehicles and Motorcycles".
