[0039] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0041] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The first embodiment

[0044] Please refer to Figure 1 , which shows the OTA upgrade method for dual - protocol collaborative work in the first embodiment of the present invention. The OTA upgrade method is applied to a vehicle, and the vehicle includes an in - vehicle terminal and a server.

[0045] It should be noted that in this embodiment, the in - vehicle terminal and the server are units commonly available in the vehicle system. Since they belong to the conventional prior art in this field, no special description will be given here.

[0046] Specifically, the control method includes:

[0047] S01, Obtain the MQTT protocol and the HTTPS protocol.

[0048] It should be noted that in a vehicle, the MQTT protocol is generally deployed in an electronic control unit (ECU) that can be connected to the network to implement functions such as remote control, remote flashing, data uploading, remote diagnosis, and OTA (Over - The - Air). The HTTPS protocol in the vehicle is a secure communication protocol used to ensure the confidentiality, availability, and integrity during the data transmission process between the vehicle and the cloud or other external systems.

[0049] Since both the above - mentioned MQTT protocol and HTTPS protocol belong to the conventional prior art in this field, no special description will be given here.

[0050] S02, When the in - vehicle terminal is running, simultaneously send a subscription request for the OTA upgrade package through the MQTT protocol and the HTTPS protocol.

[0051] S03, When the in - vehicle terminal obtains the OTA upgrade package through the MQTT protocol, the in - vehicle terminal stores the OTA upgrade package and sends the verification information of the OTA upgrade package to the server through the HTTPS protocol to verify the verification information in the OTA upgrade package.

[0052] Specifically, the verification information includes the hash value and the digest information in the OTA upgrade package.

[0053] It should be noted that the in-vehicle terminal receives the OTA upgrade package through the MQTT protocol and sends the OTA upgrade package to the device side through the MQTT protocol. After receiving the OTA upgrade package, the in-vehicle terminal stores the OTA upgrade package in the memory. Subsequently, the in-vehicle terminal sends a verification request to the server through the HTTPS protocol to verify the integrity and authenticity of the OTA upgrade package, that is, to verify the above hash value and the above summary information.

[0054] S04, if the verification information of the OTA upgrade package is qualified, the in-vehicle terminal performs the OTA upgrade package for upgrading.

[0055] Specifically, when the verification results of both the hash value and the summary information are qualified, the in-vehicle terminal performs the OTA upgrade package for upgrading;

[0056] When any one of the verification results of the hash value or the summary information is unqualified, the in-vehicle terminal does not perform the OTA upgrade package for upgrading.

[0057] In some preferred embodiments, before the step of performing the OTA upgrade package for upgrading according to the in-vehicle terminal when the verification information of the OTA upgrade package is qualified, it further includes:

[0058] Obtain the battery power parameter of the current vehicle;

[0059] When the verification information of the OTA upgrade package is qualified, comprehensively judge whether the in-vehicle terminal performs the OTA upgrade package for upgrading by integrating the battery power parameter.

[0060] Specifically, when the battery power parameter data meets the preset power parameter, the in-vehicle terminal performs the OTA upgrade package for upgrading.

[0061] When the battery power parameter does not meet the preset power data, the in-vehicle terminal does not perform the OTA upgrade package for upgrading.

[0062] That is to say, before performing the OTA upgrade, the in-vehicle terminal will check whether the battery of the current vehicle is fully charged. If the power is insufficient, it will wait until the battery is charged before performing the OTA upgrade. This can avoid the problem of vehicle power loss caused by performing the OTA upgrade when the power is insufficient.

[0063] In summary, the OTA upgrade method with dual-protocol collaborative work shown in the first embodiment has at least the following beneficial effects compared with the OTA upgrade method in the prior art:

[0064] In an OTA upgrade method with dual - protocol collaborative work provided by the present invention, the MQTT protocol and the HTTPS protocol are obtained; when the in - vehicle terminal is running, subscription requests for the OTA upgrade package are simultaneously sent through the MQTT protocol and the HTTPS protocol; when the in - vehicle terminal obtains the OTA upgrade package through the MQTT protocol, the in - vehicle terminal stores the OTA upgrade package and sends the verification information of the OTA upgrade package to the server through the HTTPS protocol to verify the verification information in the OTA upgrade package; wherein, the verification information includes the hash value and the digest information in the OTA upgrade package; if the verification information of the OTA upgrade package is qualified, the OTA upgrade package is executed according to the in - vehicle terminal for upgrade. The present invention combines the real - time nature of MQTT and the data integrity verification of HTTPS, improves the efficiency of OTA upgrade, and enhances the security of the OTA upgrade process by using dual - protocols and encryption algorithms, and can solve the technical problem that a single communication protocol in the prior art cannot simultaneously achieve high transmission efficiency and high security.
