Embodiment Construction

[0032] As described herein, the present invention includes a method for diagnosing errors of vehicle electronic components with multiple input / output ports, which includes: (a) abnormal operation of the component causing the problem through a communication network Waveform data is shared; and (b) Obtain abnormal waveform data, and reproduce the abnormal waveform data as the original input waveform to input the original input waveform to the input port of the test component, thereby testing whether the test component operates incorrectly .

[0033] In one embodiment, the abnormal waveform data is obtained by one or more of the following processes: (a-1) In the state where the problem component is electrically connected to the vehicle, input and output waveforms of the problem component in operation in real time The process of collecting at the same time; (a-2) the process of analyzing the output waveform to obtain information about the generation time point of the abnormal output ...

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.

Description

[0001] Cross references to related applications [0002] This application claims the priority of Korean Patent Application No. 2007-0133096 and No. 2007-0133097 respectively filed at the Korean Intellectual Property Office on December 18, 2007, the entire contents of which are hereby incorporated by reference. Technical field [0003] The present invention relates to a method for diagnosing errors in electronic components of vehicles. The electronic components can sample abnormal waveforms that cause erroneous operation of the electronic components, and then share the sampled abnormal waveforms on the network to improve domestic and foreign response. The performance of electronic components. Background technique [0004] When developing new electronic components, it is necessary to test whether the electronic components operate without failure. For example, after a newly developed vehicle component is installed on the vehicle, the performance of the component or the wrong operation...
