유도성 부하의 과도 전압이 파워트레인 전장품에 미치는 영향 분석

다국어 초록 (Multilingual Abstract)

In this paper, the measurement system, procedure, and analysis method for the transient voltage in an aged inductive load were introduced. First, the on/off switching, overloaded condition, and deteriorated condition were simulated for the analysis of the transient voltage on the DC power line in the virtual operation of a vehicle. In particular, the surge voltages that came from the fuel pump and wiper motor were classified as failed among the 13 targets of emission test results. In order to verify the effectiveness of the transient voltage on the CKPS and CMPS of ECU essential signal when the automobile was operated, the measurement system is created and the results are shown. Based on the results, the ECU level fluctuated over the criteria caused by the transient voltage from the repetitive operation of the fuel pump. In addition, to simulate the surge that originated from the fuel pump in the actual operation of the vehicle, the waveform defined by Ford Motor Co. was used and a similar transient voltage to that of the fuel pump was injected. It is verified that the ignition and injector signals have been affected.
