Abstract

The invention provides a data transmission method and device, vehicle-mounted equipment and a storage medium, and belongs to the technical field of automatic driving. The method comprises the steps ofobtaining a driving data set generated by a vehicle, wherein the driving data set is used for recording a driving state of the vehicle; in response to an abnormal event, screening out driving data associated with the abnormal event from the driving data set to obtain a first data subset, the abnormal event including at least one of vehicle driving abnormality, driving environment abnormality andvehicle state abnormality; and transmitting the first subset of data. According to the invention, the data subsets with the analysis value for the abnormal events are screened from the driving data set, the screened data subsets are transmitted, on the basis of transmitting valuable data, the data size of the transmitted data is reduced, the data transmission efficiency is improved, and thereforetransmission of the data with the high utilization value is achieved in a short time, and the data transmission efficiency is improved. The instantaneity of data transmission is improved.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a data transmission method, device, vehicle-mounted equipment, and storage medium. Background technique [0002] The emergence of automobiles has greatly facilitated people's lives. With the rapid development of intelligent computing, research on autonomous vehicles has become a hot topic. The data generated during the driving process of self-driving cars has important application value in scenarios such as the improvement of self-driving technology, the responsibility assessment of traffic accidents, and the abnormal analysis of driving status. [0003] The continuous upgrading of mobile networks and the continuous expansion of coverage provide a communication basis for the transmission of autonomous driving data. However, the data traffic and bandwidth of the current mobile network are limited, and do not support the real-time transmission of large amou...
