specific Embodiment approach

[0031] In order to clearly and completely describe the technical solution of the present invention and its specific working process, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:

[0032] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrated; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise specified limit. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

[0033] In the present i...

Embodiment 1

[0036] like figure 1 As shown, the present embodiment provides a cloud-configurable OTA upgrade system for automobiles, including

[0037] OTA cloud, used to configure the OTA upgrade task, and send the OTA upgrade configuration file and task package to the vehicle remote communication terminal;

[0038] The vehicle-mounted remote communication terminal TBOX is used to download the OTA upgrade package from the server in the OTA cloud, and send the downloaded OTA upgrade package to the OTA component;

[0039] The OTA component is used to analyze the OTA upgrade package sent by the vehicle telematics terminal;

[0040] The car audio entertainment system HU is used to decode the encoded file sent by the car telematics terminal and display it on the display screen;

[0041] The gateway GW is used to receive the signal and forward it to the vehicle-mounted remote communication terminal;

[0042] The controller ECU to be upgraded is used to receive the flashing upgrade task of th...

Embodiment 2

[0045] like figure 2 , image 3 and Figure 4 As shown, the present embodiment provides a cloud-configurable OTA upgrade method for automobiles, which specifically includes the following steps:

[0046]First, the OTA cloud determines the controller to be upgraded, and configures the bootloader-related files and downloads the corresponding version of the upgrade package for the controller to be upgraded; the vehicle-mounted remote communication terminal receives the OTA upgrade package and configuration file from the OTA cloud, and sends it to the OTA Component; the OTA component analyzes the configuration file sent by the vehicle telematics terminal, encodes the content of the configuration file, and then sends it back to the vehicle telematics terminal; the vehicle telematics terminal obtains the encoded file and transmits it to the vehicle audio entertainment system; the vehicle audio entertainment The system decodes the coded file and displays it on the display screen; t...

Abstract

The invention discloses a cloud-configurable automobile OTA upgrading system and method, and belongs to the technical field of automobile electronics. A to-be-upgraded controller is determined through an OTA cloud, and related file configuration and upgrading package downloading of a corresponding version are performed on the to-be-upgraded controller; the vehicle-mounted remote communication terminal receives the OTA upgrade package and the configuration file of the OTA cloud and sends the OTA upgrade package and the configuration file to the OTA assembly; the OTA component analyzes the configuration file sent by the vehicle-mounted remote communication terminal, encodes the content of the configuration file, and transmits the encoded content back to the vehicle-mounted remote communication terminal; the vehicle-mounted remote communication terminal obtains the coding file and transmits the coding file to the vehicle-mounted audio entertainment system; the vehicle-mounted audio entertainment system decodes the encoding file and displays the encoding file on a display screen; and the to-be-upgraded controller receives the flashing and upgrading task of the vehicle-mounted remote communication terminal. According to the invention, the OTA component instead of a vehicle-mounted remote communication terminal is adopted to carry out diagnosis and flashing related functions, so that the flexibility is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a cloud-configurable automobile OTA upgrade system and method. Background technique [0002] In China's thriving auto industry, with the advancement of the new four modernizations of "electrification, networking, intelligence, and sharing", its electronic procedures are also getting higher and higher. Today, "Internet of Vehicles" has become a feature of most cars, and the use of remote communication to control vehicles is becoming more and more common. At the same time, the OTA function provides convenience for the upgrade of the controller software in the car. However, the OTA upgrade process involves a lot of specialties. The vehicle remote control terminal needs to communicate, and the vehicle audio entertainment system is responsible for displaying the content related to the upgrade. Then, how to improve the controllability and flexibility of the ...
