Research Of Vehicle Electric Control Equipment Test System Based On LabVIEW

In recent years,one of the significant changes in automobile industry is that theimprovement of automobile performance more and more depends on electronic controltechnology.Research show that the proportion of electronic control equipment in thewhole vehicle manufacturing costs has growed from16%to more than30%during thepast decade. Although current cars with a large number of electronic control equipmentbecome more safety, green and intelligent,but in the train of more big and complexelectronic control system.Therefore,it becomes more and more important to test andverify electronic control system in the process of the new modle car development.Based on this background,the paper designed a automotive electronic controlequipment test system with the NI hardware platform as its core through researchingRelated products and literature about testing of automobile electronic control equipment.To gather ECU function and network testing round the lobby,the test system will offer apowerful general test platform for the automobile electronic control system.Through the analysis of automobile electronic control system test requirements andthe hardware and software requirements of test system,this paper regards car ECUfunction and network testing as the main line,design an overall plan for test system basedon NI hardware platform, complete the design and construction of the test systemhardware platform, carry out the test system software architecture design and programdevelopment.At last by operation and debugging the test system, problems of the systemwere summarized and put forward the solution.The use results of the test system showthat automobile electronic control test system based on NI platform ispowerful,flexible,efficient and convenient for secondary development.By this test systemwe not only shorten the development and testing cycle time of automobile electroniccontrol system, reduce the cost of the development and testing, but also guarantee thereliability of car electronic control system development and test process.
