AI Technical Summary

Technical Problem

Existing technologies still result in a high electrical failure rate after vehicles leave the factory, especially during the early failure period, and this problem cannot be effectively solved.

Method used

Before the vehicle rolls off the production line, an automatic aging test method is adopted. Test instructions are issued through the in-vehicle interactive system, and the execution results data of electrical functions and visual images are recorded. The results from the three parties are combined to make a judgment, monitor the failure rate, and adjust the number of tests in real time to ensure that the vehicle passes through the early failure period.

Benefits of technology

This significantly improves the accuracy and efficiency of vehicle testing before delivery, reduces the failure rate during customer use, and ensures that vehicles have passed the early failure period before delivery.

Abstract

The invention discloses an aging test method for a vehicle before leaving a factory, and particularly, the method comprises the steps: connecting aging test equipment after the vehicle leaves the factory, employing a preset automatic aging test program to run most electrical functions of the vehicle, and enabling the vehicle to expose a fault as much as possible in an early failure period, and the aging test equipment monitors the execution condition of the vehicle control instruction and returns a test result to the test platform, so that the problem is solved before delivery, and the failure rate of the vehicle in the use process of a customer is reduced. Furthermore, an instruction issued by the vehicle-mounted central control screen, data fed back by the ECU and a visual identification result are integrated through the data recorder to judge whether the vehicle-mounted central control screen, the ECU and the visual identification result are qualified or not through three-party fusion, so that the test accuracy is remarkably improved; in addition, a fault rate curve can be drawn in real time by the test platform, the aging test frequency is dynamically adjusted, and the test efficiency is improved. Therefore, before the vehicle leaves a factory and is delivered to a customer, the vehicle can pass through the early failure period before leaving the factory, and the tested fault is solved.
