Design And Implementation Of Automotive Engine Simulator

With the development of modern auto industry,people make higher requirement forthe intelligent control of automotive engine.So the core of intelligent control——ECU isbecoming more and more important.In the process of traditional ECU development,R&Dengineer need to test the ECU in the actural automotive engine before it leave factory.Thisresearch and development way makes the period of ECU development long and the costhigh.This time we will design an automotive engine simulator.It can simulate all kinds ofsignals of the automotive engine when it is working.In other words,it is equivalent to avirtual automotive engine.Connecting the simulator with the ECU can test the performanceof the ECU.The method avoids the trouble of testing ECU on actual automotive engine.Itshortens the development time and development cost of ECU.The hardware design of the simulator is divided into three parts:the circuit design ofthe core panel,the circuit design of LCD panel,and the circuit design of signal interfacepanel.The three parts include the design of power module,the design of processormodule,the design of signal generating circuit,the design of CAN bus communicationcircuit.The sofeware part includes the design of the core panel program,the design of theLCD driver program,and the design of CAN communication driver program.Atder testing,the simulator can simulate the signals of automotive engine well.It hashelped an ECU manufacturer develop a new ECU.
