Embodiment Construction

[0041] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] see figure 1 As shown, the embodiment of the present invention provides a method for collecting and remotely updating autonomous driving scene information, including the following steps:

[0043] In the process of automatic driving, when the local central processing unit receives the fault trigger signal, it collects the driving scene information for a period of time before and after the trigger signal, classifies the driving scene and analyzes the cause of the fault, and outputs the input signal of the perception fusion model and the output of the perception fusion model Signals, fault diagnosis logs and classified scene video data are sent to the cloud server through wireless optical communication;

[0044] The R&D personnel obtain the driving scene information from the cloud server, confirm the cause of the failure, and upload the re...

Abstract

The invention discloses an automatic driving scene information collection and remote upgrading method and system, and relates to the technical field of automobiles. When a driver finds a fault, a trigger signal is sent out by a manual key or an automatic driving system reports the fault signal, automatic driving scene information collection is triggered, field driving scenes within a period of time before and after the trigger signal are collected, the driving scenes are classified, fault reason analysis is carried out, and the scenes are uploaded to a cloud server. And meanwhile, research anddevelopment personnel repair the automatic driving system by analyzing the scene, and the automatic driving system can be remotely upgraded through the device so as to process reported faults, so that the user experience is greatly improved, and the after-sales service cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for collecting and remotely upgrading scene information of automatic driving. Background technique [0002] The key to safe driving of self-driving vehicles is to accurately and timely recognize the driving environment around the vehicle, that is, the driving scene. China's road traffic construction is not only uneven in level, but also has regional characteristics. At present, many companies hope to build special scene test proving grounds to conduct autonomous driving tests. However, the real situation is that there are countless driving scenes, and there are many reasons for accidents. Various, weather factors also have a very important impact, it is difficult for the test site to exhaustively build all the test scenarios. [0003] It is difficult to reproduce the driving scene at the scene of the accident, and if there is no on-site driving scene, it ...
