Vehicle internet gateway, vehicle ota upgrade system and method, computer storage medium

Abstract

The present invention provides a vehicle-mounted Internet gateway, a vehicle OTA upgrade system, a vehicle OTA upgrade method, a computer storage medium, and a vehicle, so as to realize a one-stop OTA refresh solution by using the vehicle-mounted Internet gateway, and can complete the upgrade and refresh of the intelligent controller on the vehicle , and can complete the upgrade and refresh of non-intelligent controllers of all CAN subnets, and can also make all OTA control strategies be completed inside the vehicle Internet gateway, thus forming a unified refresh strategy and file format, so that OEMs can Unify the vehicle OTA upgrade and refresh schemes of different models and different configurations; further, a more in-depth customized vehicle OTA upgrade and refresh scheme can be given, such as individual refresh of each module of each controller, refresh sequence configuration and Multi-subnet parallel refresh, etc.

Description

technical field [0001] The invention relates to the technical field of automobile communication, in particular to a vehicle-mounted Internet gateway, a vehicle OTA upgrade system, a vehicle OTA upgrade method, a computer storage medium and a vehicle. Background technique [0002] With the progress of society, cars have almost become a necessary means of transportation for every household, making people's lives more and more convenient. And 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) According to statistics, an average family car today contains 30 ECUs on average, and each ECU usually includes a control module and a storage module, and the storage module is used to store software and parameters of devices or functions related to the ECU....

AI Technical Summary

Problems solved by technology

[0006] 1. The above-mentioned OTA upgrade scheme adopts multi-master node cooperation methods such as T-BOX, GW, BCM, TGC, BMS, EMS, etc., the communication link is long, there are many interactions between master nodes, the data protection ability is poor, and the development cycle is long;

[0007] 2. The above-mentioned OTA upgrade solution is generally completed jointly by multiple suppliers, and it is difficult to form a unified strategy and data format. When the model or vehicle configuration is changed, it is often necessary to re-customize the strategy development;

[0008] 3. The above-mentioned OTA upgrade solution usually only has the processing capabilities of the cloud and intelligent controllers (that is, ECUs with intelligent operating systems such as Linux, referred to as smart ECUs), while for traditional controllers on cars (that is, with embedded real-time The OTA upgrade and refresh of the ECU of the operating system (non-intelligent ECU for short) generally requires cross-field cooperation to form a complete OTA service, and there are many interactions, which cannot form an overall advantage;

[0009] 4. The above OTA upgrade solution cannot deeply customize the upgrade and refresh of each ECU, such as refresh sequence judgment, ECU module-level refresh control, refresh failure processing and rollback strategy, etc.
