MULTIPLE TEST SYSTEM OF SIDE AIR BAG ECU

摘要

PURPOSE: A multiple test system of a side air bag ECU(Electronic Control Unit) is provided to start a specific side air bag test after connecting plural side air bag ECUs in a run-in chamber with a computer through an interface for multiple test. CONSTITUTION: A multiple test system of a side air bag ECU consists of: a computer(10) transmitting a test signal for testing the n number of side air bag ECUs, and receiving a response signal of the input test; a run-in chamber(20) changing indoor temperature according to a temperature control signal input from the computer to change the indoor temperature according to test items, having the n number of side air bag ECUs; and an interface(30) transmitting the test signal converted into a voltage signal of the computer to the n number of side air bag ECUs in the run-in chamber selectively, and transmitting the voltage signal converted into a response signal for test by detecting an electric current signal from the voltage signal. The multiple test system starts a specific side air bag test after connecting the plural side air bag ECUs with the computer through the interface. Therefore, the processing time of the test is shortened remarkably.
