Abstract

The invention discloses a whole vehicle ECU software wireless upgrading method which is characterized by comprising the following three steps: S10, a version information synchronization module collects version information of each ECU software of a local vehicle and uploads the version information to a background in a wireless mode, and it is ensured that the version information of each ECU software stored in the background is the latest information; s20, the task downloading module actively queries whether the background has available upgrading tasks or not, requests downloading when the upgrading tasks exist, downloads ECU software versions needing to be upgraded from the background in a wireless mode, and waits for authorized installation; and S30, a guiding upgrading module is used for guiding upgrading processes of a plurality of ECUs of a local automobile, flashing the latest ECU software version downloaded from the background into a target ECU, and upgrading the ECU. According to the invention, wireless upgrading of the automobile ECU software is achieved, and an interactive interface among an automobile factory, an automobile owner and an ECU unit supplier in upgrading is more friendly.

Description

technical field [0001] The invention relates to the field of automobile electronic control, in particular to a method for wirelessly upgrading the ECU software of the whole vehicle. Background technique [0002] The software upgrade of the traditional car ECU requires the car owner to drive to the 4S shop. The upgrade takes several days, which is extremely inconvenient for the car owner. After the car factory produces cars in large quantities, if it is necessary to upgrade the ECU unit, the car manufacturer needs to do it one by one, and upgrade each ECU for each car separately, and the time cost and labor cost are very high. For the current automotive ECU suppliers, if the relevant software needs to be upgraded, it can only be upgraded when the car owner goes to the 4S store. The upgrade needs to be approved by the car owner. This communication process increases the time cost of the car owner and the 4S store. Contents of the invention [0003] In view of the above-menti...
