Abstract
Disclosed is a simulation test system and method for testing a vehicle electronic component capable of easily testing performance of the electronic component anytime regardless of location without repeating the same driving test.
Claims17
A simulation test system for a vehicle electronic component comprising:
- at least one attenuation probe that is connected to input lines of operating sample components in a state where they are electrically connected to the vehicle;
- a data collector that has multi-channels connectable to the attenuation probe at a ratio of 1:1 and periodically stores input and output waveforms input in real time through the multi-channels, together with a sampling time and channel information for each waveform;
- a waveform generator that not only reproduces the obtained waveform data into original waveforms through the multi-channels using the data collector but also synchronously reproduces the waveforms for each channel;
- and
- an amplifier that amplifies the waveforms reproduced in the waveform generator.

A simulation test method for a vehicle electronic component comprising a plurality of input and output ports, comprising:
- (a) a process sharing, through a communication network, a database where waveform data for at least one sample component is sorted according to at least test conditions, wherein the waveform data are obtained in real time by a process collecting at least input waveforms of operating sample components electrically connected to the vehicle that are input to the input ports while driving the vehicle under specific test conditions, wherein the specific test conditions include at least one of a road on which the driving test is performed, a region, a climate, and driving conditions;
- and
- (b) a process testing a state of the tested components by obtaining the specific waveform data in the database, reproducing the obtained waveform data into the original input waveforms, and inputting the reproduced waveforms to the input ports of the tested components.
