Research on Non-Standard Transient Conduction Waveform Measurement of Automotive Low Voltage Electronic Components

ISO 7637-2:2011 is the main standard for electrical transient conducted immunity test of automotive lowvoltage electronic components. It provides signals of different strength and different parameters for manufacturers to verify product performance of their products. However, with the development of the automotive industry, more and more signals not included in ISO 7637-2:2011 have been found to affect automotive electrical and electronic components and threaten vehicle safety. Detailed analysis and elaboration of these nonstandard signals has been provided in this paper, which can explain many vehicle failure problems during start-up, driving and parking.
