Data storage device and method, black box, vehicle, controller and medium

Abstract

The invention relates to a data storage device and method, a black box, a vehicle, a controller and a medium. The device comprises a first storage area for storing vehicle data collected by a vehicledevice in real time, a detection module for detecting whether a preset event occurs, and a second storage area for storing vehicle data in a preset time period acquired from the first storage area andthe vehicle device when the preset event occurs. Through adoption of the method, vehicle data is stored safely and reliably, and desired data is convenient to acquire.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage device and method, a black box, a vehicle, a controller and a medium. Background technique [0002] With the rapid increase in the number of vehicles, the development of autonomous driving technology and other factors, vehicle traffic accidents will inevitably occur. The determination of accident responsibility is particularly important. The vehicle black box can record vehicle data and provide evidence for the identification of accident responsibility. [0003] However, in the existing vehicle-mounted black box, when the storage space is insufficient, the vehicle data in the previous period of time will be deleted or overwritten. Therefore, when the accident is identified, the required accident-related data may have been lost. [0004] In addition, the black box may be damaged in a vehicle accident, resulting in data loss; for example, electric vehicles gener...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing vehicle black box, when the storage space is insufficient, the vehicle data in the previous period of time will be deleted or overwritten. Therefore, when the accident is determined, the required accident-related data may have been lost

[0004] In addition, the black box may be damaged in a vehicle accident, resulting in data loss; for example, electric vehicles generally use high-capacity, high-density batteries (such as ternary batteries). Combustion can also occur in the state of oxygen, so the vehicle is facing the risk of fire after a severe collision accident, which will damage the data stored in the black box of the vehicle

[0005] Even if the data related to the accident is not lost, when the accident is identified, it is necessary to find the relevant accident data according to the time period of the accident, which is inconvenient and the user experience is poor

[0006] Due to the application of the Internet of Vehicles, vehicles are also facing threats to network security, and the privacy and security of users' vehicle data cannot be reliably guaranteed
