The simulation of crankshaft and camshaft position sensor signals is realized by combining LabCar hardware with software. The difference between analog signal and theory speed signal is compared and analyzed. The results show that the crankshaft and camshaft position sensor signals simulated by LabCar are consistent with theory signal. The analog signals can be exactly identified by ECU. The test efficiency of high-pressure common rail ECU hardware in loop was improved. It is of practi-cal value.
