摘　　要：为实现汽车仪表全功能检测及显示策略验证,利用实车数据搭建仿真测试环境。通过上位机读取实车数据脚本,经串口将数据发送给电控单元,电控单元控制产生仪表信号,实现仪表功能测试。利用步进电机带动滑动变阻器模拟油浮子采集油量阻值原理,实现实车油量数据的仿真。基于win32平台开发数据分析环境,对实车数据提取分析,为仪表中控制策略、显示算法提供数据依据。根据信号源制定通用的脚本协议,可以满足多种仪表规范的测试需求。通过多款仪表测试,本平台具有良好的实用性、通用性,且能大大缩短液晶仪表的研发、测试周期。In order to realize the full function test and display strategy verification of the automobile instrument,a simulation test environment is built by using the actual vehicle data.The host computer reads the real data script,and the serial data are sent to the electronic control unit,and then the electronic control unit controls instrument signal to realize instrument function test.The stepper motor is used to drive the sliding rheostat to simulate the oil fuel consumption value of the oil float and realize the simulation of the actual fuel quantity data.Based on win32 platform development data analysis environment,the actual vehicle data extraction analysis is realized to provide data basis for the instrumentation control strategy and display algorithm.A common script protocol is developed according to the source to meet a variety of instrument specifications test requirements.A variety of instrumentation tests show the platform has a good practicality,versatility,and can greatly shorten the LCD instrument research,development and testing cycle.
