Abstract

The invention discloses an upgrading method and device for the electronic control unit of a vehicle, a vehicle control circuit and the vehicle. The method comprises the following steps that: obtainingthe identification of the electronic control unit and a first corresponding program file version from a server; obtaining the identification of at least one electronic control unit and a corresponding second program file version on the vehicle; judging whether the first program file version corresponding to the identification of the same electronic control unit is higher than the second program file version or not; when the first program file version corresponding to the identification of the same electronic control unit is higher than the second program file version, taking the electronic control unit of which the first program file version is higher than the second program file version as an electronic control unit to be upgraded, and sending the identification of the electronic controlunit to be upgraded to the server; receiving a program file corresponding to the identification, which is sent from the server, of the electronic control unit; and utilizing the received upgrading file to upgrade the corresponding electronic control unit to be upgraded.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method and device for upgrading a vehicle electronic control unit, a vehicle control circuit and a vehicle. Background technique [0002] The functions of current vehicles are becoming more and more complex and perfect, and there are usually multiple electronic control units (ECU, Electronic Control Unit) on the vehicle to control the driving system, transmission system, braking system, etc. of the vehicle. In order to improve the functions of vehicles, manufacturers need to continuously upgrade the ECU to improve the driving experience of users. [0003] At present, there is a technology to remotely upgrade the software such as navigation in the vehicle through OTA (Over-the-Air Technology) technology. Like a smartphone, the user can remotely connect to the server to upgrade the software of the vehicle. However, for the upgrade of the vehicle ECU , the user still...
