Considering the limitation of traditional development method of engine management system(EMS),a method to establish sensor-fault simulation system was proposed.Firstly,a hardware-in-the-loop simulation platform,which was used for EMS function test,was developed in the LabVIEW and VeriStand environment.Secondly,by using this platform,a sensor-fault simulation system was set up for throttle position,intake air pressure,and engine water temperature.Finally,the real vehicle test of throttle position sensor-faul...
