Problems solved by technology

However, in the way of downloading the installation package and coordinating the upgrade of other nodes through the OTA master module, the OTA master module needs to download and distribute the upgrade packages of multiple OTA slaves, which will bring a great burden to the storage and load of the OTA Master, making the vehicle The upgrade efficiency and vehicle stability of the
For example, if the upgrade package is large, the storage space of the OTA Master may not be enough, so that some vehicle components cannot be upgraded in time
For another example, as the structure of the vehicle becomes more and more complex, the efficiency of upgrading the vehicle in this way will become lower and lower, which cannot meet the needs of users

Abstract

The embodiment of the invention provides a vehicle upgrading method and device, and the method comprises the steps that a server determines at least two part groups in a vehicle, and each part group comprises an upgrading control part which is used for controlling a part in the part group to carry out OTA upgrading; the server generates a first upgrade package for a first component group in the at least two component groups, and an upgrade control component of the first component group is a first upgrade control component; and the server sends the first upgrade package to the first upgrade control component, wherein the first upgrade package is used for upgrading components in the first component group. By adopting the embodiment of the invention, the vehicle upgrading efficiency can be improved, and the vehicle stability is improved. The scheme can be further used for improving the ADAS capability of an automatic driving or advanced driving assistance system, and can be applied to the Internet of Vehicles, such as vehicle external V2X, inter-vehicle communication long-term evolution technology LTE-V, vehicle-vehicle V2V and the like.

Description

Technical field[0001]The present application relates to the technical field of netcraft, and more particularly to a vehicle upgrade method and apparatus.Background technique[0002]Air Download Technology (OVER THE AIR, ORO) is a technology downloaded through a wireless network, which is now widely used in the upgrade of smart TV, mobile phones, tablets, set-top boxes. OTA technology is mainly downloaded from the OTA upgrade package through the network (such as WiFi, 3G, 4G, etc.) (also supported by downloading the OTA upgrade package to SD card to upgrade), OTA upgrade speed is fast, the impact on the data is small, so The development of the smart network car, OTA upgrade has become the main way for vehicle functional upgrades, vehicle manufacturers (or original equipment manufacturers (ORIGINAL EQUIPMANUFACTUREER, OEM), is conducive to manufacturers through OTA technology upgraded vehicles Reduce recall costs, quickly respond to demand, and enhance user experience.[0003]The vehicle ...
