Function test system applied to automobile electronic control unit, and control method thereof

Abstract

The invention discloses a function test system applied to an automobile electronic control unit. The system includes: an industrial computer, a direct current power supply, a desk type digital multimeter, a signal generator, a matrix module, a power supply transformation module, a communication transformation module, a high-power switch group, a current loop, a simulation load, a needle bed jig, a bar code scanning device, a signal indicating lamp, a direct current matrix switch, an emergency stop button, an electricity leakage circuit breaker, a cooling fan, a display, a UPS (uninterruptible power supply), and an alternating current extension module. Each module of the system is independent; the overall performance is more reliable; the upgrade of an independent module does not affect other modules to work; and the reliability in using the function test system is ensured.

Description

technical field [0001] The invention relates to the technical field of automotive electronic measurement and control, in particular to a method for testing automotive electronic control units. Background technique [0002] In the field of automotive electronic control unit measurement and control technology, at present, in order to improve production efficiency and save production costs, the functional test system of automotive electronic control units requires a fully automated test solution. The earliest functional tests mainly use manual and semi-automatic test solutions. There will be the following defects: [0003] 1. Due to the traditional automotive electronic control unit function test system, it is bulky and scattered, the degree of integration is not high enough, and the cost is high; [0004] 2. Due to the traditional automotive electronic control unit function test system, the hardware and software are relatively independent, and the system circuit is relatively...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the traditional automotive electronic control unit function test system, it is bulky and scattered, the degree of integration is not high enough, and the cost is high;

[0004] 2. Due to the traditional automotive electronic control unit function test system, the hardware and software are relatively independent, and the system circuit is relatively complicated. As long as there is a problem in one part of the circuit, it will affect other circuit parts in the system, and the reliability of the hardware circuit is low.
