Abstract: A general auto dashboard detection platform is developed for lack of integration, versatility and several other problems in the current dashboard detection platform, which can detect the accuracy of display data as well as the working condition of other digital signal indicators in CAN bus and ordinary auto dashboard. Virtual instrument based on VC++6.0, CAN bus, dashboard statement comparison, and other technology and methods are used in the detection platform. By the actual detection for CAN bus and ordinary auto dashboard, results show that the test platform has great integration and versatility.

Key words: auto dashboard, dashboard detection platform, virtual dashboard, CAN bus, pulse signal, resistance signal

摘要： 针对目前仪表检测缺乏集成性、通用性等问题，开发一款通用的汽车仪表检测平台，用以检测汽车CAN总线仪表与普通数字仪表常见表盘指示数据的精度，以及信号报警指示装置的工作状态。该平台采用基于VC++6.0的虚拟仪表、CAN总线、仪表指示状态对比等技术方法。对普通数字仪表与CAN总线仪表进行实际测试，结果表明，该平台具有良好的集成性与通用性。
