摘　　要：通过LabCar软硬件结合实现了曲轴与凸轮轴位置传感器信号模拟,对比分析研究了模拟信号与理论转速信号的差异。结果表明,基于LabCar模拟出的曲轴凸轮轴位置信号与理论信号一致,模拟信号能被ECU精确识别,从而提高了高压共轨ECU硬件在环测试效率,具有很好的应用价值。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.
