Problems solved by technology

[0007] 1. At present, because there are many test points that the vehicle information system needs to pay attention to (such as image output, audio output, current output, and network communication, etc.), most of them are manually tested.
[0008] 2. Due to manual testing, different personnel have different judgment standards for the same phenomenon, resulting in di...

Abstract

The invention discloses a vehicle-mounted information system test bench and a test method, so that a fault is reproduced to facilitate development and testing, and the period for fault solution is greatly shortened. The technical scheme is as follows: an autonomous system software environment is established, a video monitoring comparison device, an audio monitoring device, a current monitoring device and a CAN (Controller Area Network) bus network monitoring device are utilized to form the vehicle-mounted information system test bench, and image data, audio data, current data, CAN network information data and the like can be automatically recorded when the fault occurs, and scene playback is carried out by utilizing a fault retrospect playback device, so that the fault is reproduced to facilitate development and testing, and the period for fault solution is greatly shortened.

Description

technical field [0001] The invention relates to a test technology of a vehicle information system, in particular to an unattended test platform and a test method of the vehicle information system. Background technique [0002] At present, in order to cooperate with the new models launched by manufacturers and meet the needs of users, the in-vehicle information system is gradually developing towards multi-function and high integration. Complex functions, high integration, and a relatively tight development cycle have brought great troubles to the development and testing of vehicle information systems. For example, the real environment of the target model cannot be used for testing in the early stage of the project. How to use a low-cost bench to conduct high-coverage tests in the shortest possible time, and efficiently discover, locate, analyze, and verify problems is a key difficulty. At the same time, repeated high-intensity tests and subjective judgment results that vary ...
