Abstract

A method for diagnosing an error of a vehicle electronic component capable of being performed without an actual driving test by building up a database of unusual waveform data that generates an erroneous operation of a vehicle electronic component is disclosed. The unusual waveform data are obtained through a process simultaneously collecting input and output waveforms of a problematic component in operation in real time in a state where the problematic component is electrically connected to a vehicle; a process analyzing the output waveforms to obtain information on a point in time of generation of an unusual output waveform that causes an erroneous operation of the problematic component; and a process extracting input waveforms during a predetermined time before and after the point of time of generation of the unusual output waveform using the information on the point in time.

Example

[0034]As described herein, the present invention includes a method for diagnosing an error of a vehicle electronic component with a plurality of input / output ports comprising (a) a process of sharing unusual waveform data that cause an erroneous operation of a problematic component through a communication network; and (b) a process of obtaining the unusual waveform data and reproducing the unusual waveform data into original input waveforms to input the original input waveforms to input ports of a test component, thereby testing an erroneous operation or not of the test component.

[0035]In one embodiment, the unusual waveform data are obtained through one or more of (a-1) a process of simultaneously collecting input and output waveforms of the problematic component in operation in real time in a state where the problematic component is electrically connected to a vehicle, (a-2) a process analyzing the output waveforms to obtain information on a point in time of generation of an unusu...
