Remote upgrading method, device and system for vehicle-mounted system and storage medium

Abstract

The embodiment of the invention discloses a remote upgrading method, a device and a system for a vehicle-mounted system and a storage medium. The method comprises the steps: downloading an upgrading package of the vehicle-mounted system from a cloud, and determining the remaining electric quantity of a vehicle battery through the battery voltage, battery temperature and a preset electric quantitycurve; judging whether the residual electric quantity is greater than an upgrading electric quantity or not, wherein the upgrading electric quantity is the electric quantity required for upgrading thevehicle-mounted system and determined on the basis of the upgrading package; and if so, executing an upgrading operation according to the upgrading package. According to the scheme, whether the residual electric quantity of the battery meets the upgrading electric quantity or not can be judged in the remote upgrading process, and the upgrading operation is executed under the condition that the electric quantity required by upgrading is met, so that the problem of upgrading failure caused by insufficient electric quantity in the conventional remote upgrading process at present is avoided, andnormal upgrading and use of the vehicle-mounted system are ensured; and the driving safety of the vehicle is ensured.

Description

technical field [0001] The embodiment of this specification relates to the field of automobile technology, and in particular to a remote upgrade method, device, system and storage medium for a vehicle system. Background technique [0002] With the improvement of vehicle technology, vehicles are equipped with in-vehicle systems for controlling vehicles. In order to improve the driving experience of users and ensure driving safety, automobile manufacturers generally update and upgrade the in-vehicle systems. [0003] At present, in the process of upgrading the in-vehicle system, many car manufacturers gradually use the remote method to upgrade the in-vehicle system, that is, after the user's vehicle communicates with the manufacturer's server remotely, the manufacturer's server sends an upgrade package and downloads it on the vehicle. After completion, perform the upgrade operation according to the upgrade package. However, in practical applications, since the essence of the ...

Problems solved by technology

In this way, when the outside temperature at the location of the vehicle is low during the upgrade process, the performance of the battery is affected by the low temperature outside, and it is very easy to cause the upgrade failure due to insufficient power, so that the on-board system cannot be started due to the failure of the upgrade, which affects the driving of the vehicle.

Therefore, the remote upgrade process of the existing in-vehicle system is easily affected by external weather and other factors, resulting in the problem of upgrade failure
