A system and method for remotely upgrading vehicle-mounted controller software

Abstract

The invention relates to a system for remotely upgrading full vehicle-mounted controller softwares and an upgrading method thereof. The method comprises the following steps: receiving a bus upgrading command sent by a server and confirming a to-be-upgraded vehicle-mounted controller according to the bus upgrading command; obtaining a corresponding file upgrading package of the to-be-upgraded vehicle-mounted controller from stored file upgrading packages; obtaining file package data of the file upgrading packages; sending a pre-upgrading command to all vehicle-mounted controllers; receiving pre-upgrading command executing results returned by all the vehicle-mounted controllers according to the pre-upgrading command; and when the pre-upgrading command executing results are successful, sending the obtained file package data to the to-be-upgraded vehicle-mounted controller. The method provided by the invention has the advantage that the remote upgrade of the full vehicle-mounted controller softwares can be realized without dismantling a cover plate of an OBD (On Board Diagnostics) interface.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a system and an upgrading method for remotely upgrading the software of a vehicle-mounted controller.

AI Technical Summary

Problems solved by technology

[0005] 1. The on-board controller software cannot be upgraded remotely like the on-board terminal. The car owner needs to drive the car to the 4S shop in the parking lot to upgrade the on-board controller software. The software upgrade is inconvenient and inefficient;

[0006] 2. It is necessary to remove the OBD port cover for software upgrade, which increases the risk of scratches on the interior and easily causes failure of other parts of the car
