Abstract

The embodiment of the invention provides a vehicle upgrading method and device, and the method is based on a preset vehicle upgrading architecture, the preset vehicle upgrading architecture comprisesan upper computer for online upgrading, a central gateway, and a plurality of communication channels, and the plurality of communication channels are respectively connected with the upper computer through the central gateway. The method comprises the steps of enabling the upper computer to obtain a to-be-upgraded ECU list for a to-be-upgraded vehicle, wherein the to-be-upgraded ECU list comprisesa plurality of to-be-upgraded ECUs; determining a communication channel corresponding to each ECU to be upgraded according to the list of the ECUs to be upgraded; and upgrading the ECUs to be upgradedin parallel through the corresponding communication channels. The upgrading strategy of the multi-channel ECU parallel software is completed based on the multiple communication channels, the whole vehicle software upgrading speed is increased, the software upgrading success rate is increased and the vehicle power consumption is reduced by shortening the vehicle software upgrading time, and the unnecessary upgrading waiting time is shortened.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle upgrading method and a vehicle upgrading device. Background technique [0002] With the development of various advanced technologies in the automotive field, more and more intelligent devices and functions are integrated into the car, and these devices and functions are usually controlled by the corresponding ECU (Electronic Control Unit, electronic control unit). As well as the software of on-board electronic equipment is becoming more and more complex, the probability of software problems will increase accordingly. It is often possible to iterate and update the vehicle software to ensure the safety of the car and the normal use of various functions. [0003] However, the traditional automotive software upgrade strategy is based on a single ECU upgrade method, which cannot meet the growing demand for automotive software upgrades in the future.
