Abstract

The disclosure relates to an air upgrading method of a vehicle, electronic equipment and the vehicle, and relates to the technical field of vehicle control. The method comprises the steps of determining a target length of a swipe data frame corresponding to an air upgrade instruction under the condition that the air upgrade instruction is received, wherein the air upgrade instruction is used for indicating a vehicle controller of a vehicle to upgrade, obtaining a maximum length of the swipe data frame supported by the vehicle controller, adjusting the target length based on the maximum length under the condition that the maximum length is not equal to the target length, and executing upgrade operation indicated by the air upgrade instruction of the vehicle controller. According to the embodiment of the disclosure, even if the maximum lengths supported by the vehicle controllers are different, the success of OTA upgrading can be ensured, and an over-the-air upgrading program does not need to be independently developed for each different vehicle controller hardware possibly set by the vehicle, so that the success rate of over-the-air upgrading can be improved.

Description

Air upgrading method of vehicle, electronic equipment and vehicle Technical Field The disclosure relates to the technical field of vehicle control, and in particular relates to an air upgrading method of a vehicle, electronic equipment and the vehicle. Background Along with the updating iteration of the whole vehicle technology, the vehicle functions are continuously updated. Many new functions can be upgraded to a sold vehicle by Over The Air (OTA). In the related art, OTA upgrade to a vehicle controller is performed by a Head Unit (HUT). OTA upgrades need to follow specific protocols and specifications. The HUT needs to check that the maximum data length supported by the controller in the header file (HEADER FILE) is the same as the maximum data length actually supported by the controller when performing an OTA upgrade. The controller hardware used in the production of different batches of vehicles of the same model may be different, as may the maximum data length supported by the same model. While the OTA header file of the HUT only supports one type of flush length, this results in the problem that the OTA upgrade for all the already-sold vehicles fails to upgrade on vehicles that partially apply different controller hardware. Disclosure of Invention In order to solve the technical problems, the disclosure provides an over-the-air upgrading method of a vehicle, electronic equipment and the vehicle, which can avoid failure of OTA upgrading of a vehicle partially applying different controller hardware and improve the success rate of OTA upgrading.
