It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is also to be understood that the terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to a determination" or "in response to a detection". Similarly, the phrase "if it is determined" or "if a [ described condition or event ] is detected" may be interpreted contextually to mean "upon determining" or "in response to determining" or "upon detecting [ described condition or event ]" or "in response to detecting [ described condition or event ]".
At present, the upgrade scheme of the vehicle-mounted device generally has the following forms:
1. upgrading is carried out through a USB.
In this scheme, after the vehicle-mounted device is usually detached from the vehicle, an upgrade package is acquired through a Universal Serial Bus (USB) interface to perform upgrade. If the shell of the vehicle-mounted equipment is not reserved with the USB port, the shell of the vehicle-mounted equipment needs to be detached. Therefore, the scheme is feasible in the research and development stage, and after the vehicle-mounted equipment leaves a factory and is loaded, the operation of upgrading the vehicle-mounted equipment is inconvenient and the equipment is easy to damage.
2. And performing Air upgrade by FOTA (Firmware Over-The-Air) cloud upgrade technology.
In this scheme, generally, the vehicle-mounted device is connected to a server providing the upgrade package through a 4G network, and downloads the upgrade package from the server for upgrading. However, the cost of this scheme is high, and developers need to build a server in advance or purchase a third-party service to enable the on-board device to perform 4G network connection, which increases the cost. In addition, downloading the upgrade package requires a large amount of traffic and also requires a large cost. Moreover, after the network is upgraded, for example, from the 4G network to the 5G network, the SIM card in the vehicle-mounted device needs to be replaced, which is also cumbersome.
3. And the vehicle-mounted equipment performs hot spot acquisition and upgrading on the upgrade package.
In the scheme, the mobile phone or the desktop computer used for providing the upgrade package can only be connected with the hot spot of one vehicle-mounted device at one time, when the vehicle-mounted devices required to be upgraded are more, the efficiency is low, the connection between different vehicle-mounted devices and the mobile phone or the desktop computer providing the upgrade package needs to be established repeatedly, the work is complicated, and fatigue is easily caused. In addition, the mobile phone or the desktop computer providing the upgrade package in the scheme has to know the hot roll name and the password of the vehicle-mounted device. If the in-vehicle device is already mounted to the vehicle, it may not be upgraded because it is difficult to determine the hot roll name and password of the in-vehicle device.
Therefore, the operation of the upgrading scheme of the current common vehicle-mounted equipment is often more complicated, and the efficiency is lower.
Through the embodiment of the application, the vehicle-mounted equipment can be upgraded quickly and conveniently.
Specifically, in order to explain the technical means described in the present application, the following description will be given by way of specific examples.
Fig. 1 is a schematic view of an implementation flow of an upgrading method provided in an embodiment of the present application, where the upgrading method is applied to a vehicle-mounted device.
The specific model, structure and current state of the vehicle-mounted device are not limited herein. The vehicle-mounted device may be in a development state, an uninstalled state after leaving a factory, or may have been installed in a specified vehicle. In one example, a Telematics Box (TBOX) may be included in the vehicle-mounted device.
As shown in fig. 1, the upgrading method may include the steps of:
step S101, receiving a data packet broadcasted by the terminal equipment, wherein the data packet comprises a hotspot name of the terminal equipment.

Step S103, obtaining an upgrade package broadcasted by the terminal equipment through hotspot connection, and upgrading according to the upgrade package.
In step S101, the terminal device may be different from the in-vehicle device. For example, the terminal device may be an Electronic Control Unit (ECU), a server, a desktop computer, a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like. The embodiment of the present application does not set any limit to the specific type of the terminal device.
The data packet may include a hotspot name of the terminal device, and in some examples, the data packet may further include a hotspot password of the terminal device. Through the data packet, the vehicle-mounted equipment can acquire hotspot information capable of establishing hotspot connection with the terminal equipment.
The manner in which the in-vehicle device receives the data packet broadcast by the terminal device is not limited herein. In one example, the in-vehicle device may receive a data packet broadcast by a terminal device in promiscuous mode.
In step S102, the hotspot connection may be a local area network between the vehicle-mounted device and a terminal device such as a mobile phone or a desktop computer, and a server does not need to be connected, which saves the cost of building the server. In addition, data transmission through the hotspot connection does not need to consume flow as in the case of an over-the-air upgrade scheme and the like, so that the hardware cost and other resource consumption are low.
The hot spot in the hot spot connection may be sent by a terminal device such as a mobile phone or a desktop computer. At this time, the number of the vehicle-mounted devices that establish the hotspot connection with the terminal device such as the mobile phone or the desktop computer may not be limited. That is to say, in this example, terminal devices such as a mobile phone or a desktop computer are used as hotspots, hotspot connection can be conveniently established with a plurality of vehicle-mounted devices, and an upgrade package can be simultaneously sent to the plurality of vehicle-mounted devices in a broadcast manner, so that upgrade of the plurality of vehicle-mounted devices is realized, and upgrade efficiency of the plurality of vehicle-mounted devices is greatly improved.
In step S103, after the vehicle-mounted device establishes the hotspot connection, a process of receiving an upgrade package may be started. Specifically, the vehicle-mounted device may initialize a socket to receive the upgrade package, so that the vehicle-mounted device is upgraded through the upgrade package.
Therefore, the following beneficial effects can be achieved through the embodiment of the application:

(2) The vehicle-mounted equipment acquires the upgrade package through hotspot connection, the hotspot connection is a local area network between the vehicle-mounted equipment and terminal equipment such as a mobile phone or a desktop computer, a server does not need to be connected, the cost for building the server is saved, and the data transmission through the hotspot connection does not need to consume flow as the scheme of air upgrade and the like, so that the hardware cost and other resource consumption are low.
(3) And the data packet and the upgrade packet are broadcasted through the terminal equipment. At this moment, the number of the vehicle-mounted devices connected with the terminal device can be unlimited, so that the hotspot connection between one terminal device and a plurality of vehicle-mounted devices can be realized in some scenes, and then the terminal device sends the upgrade package to the plurality of vehicle-mounted devices simultaneously, so that the efficient upgrade of the plurality of vehicle-mounted devices is realized.

step S202, if the network data packet is monitored to contain the data packet broadcasted by the terminal equipment, the data packet is received.
In the embodiment of the present application, the promiscuous mode (promiscuous mode) refers to a network card of a device being capable of receiving all data streams passing through it, regardless of whether its destination address is the promiscuous mode. In the promiscuous mode, the vehicle-mounted device can monitor network data packets broadcast by terminal devices such as mobile phones and desktop computers, and can search the monitored network data packets for the existence of data required by the vehicle-mounted device.
Wherein, before executing step S201, the in-vehicle apparatus may turn on the promiscuous mode at a specified operation node. For example, in some examples, the in-vehicle device may turn on the promiscuous mode after each power-on, or may turn on the promiscuous mode periodically at preset time intervals (e.g., 3 days, 7 days, or 3 days). The time for the vehicle-mounted device to start the promiscuous mode may be preset by a research and development staff before the vehicle leaves a factory, so that after the vehicle-mounted device is mounted on a specified vehicle, the promiscuous mode may be automatically started at a specified operation node according to preset information, so that the vehicle-mounted device may execute the embodiment of the present application.
In the embodiment of the application, the vehicle-mounted device can actively monitor the network data packet in the hybrid mode, so that the hot connection is actively established according to the hot name of the terminal device in the data packet, an upgrade person is not required to know the name, the password and other information of the hot connection, and the vehicle-mounted device is controlled in a complex control mode to establish the wireless connection. In addition, the promiscuous mode can monitor all network data packets without filtering the network data packets, so that any network data packet cannot be missed, and the data packets broadcasted by the terminal equipment can be monitored in time.
In some embodiments, the step S202 of receiving the data packet if it is monitored that the network data packet includes a data packet broadcasted by the terminal device, includes:
detecting whether the data packet exists in the network data packet or not, wherein the data packet meets a preset identification condition, and the preset identification condition indicates that the head and/or the tail of the data packet contain a preset identification; if the network data packet contains the data packet, initializing a socket, and receiving the data packet through the socket;
and carrying out decryption operation on the data packet to obtain the hotspot name.
In the embodiment of the application, whether the received network data packet is the data packet can be determined by judging whether the packet header and/or the packet tail contain the preset identifier. The preset identifier may be pre-configured by research and development personnel before leaving a factory, and therefore, after the vehicle-mounted device is installed on a designated vehicle, the data packet can be quickly searched according to pre-configured preset identifier information. The size, form, etc. of the preset mark may be various, and are not limited herein.
In some embodiments, the step 102 of establishing a hotspot connection with the terminal device according to the hotspot name includes:
closing the promiscuous mode and socket connection;
and after the hybrid mode and the socket connection are closed, establishing hotspot connection with the terminal equipment according to the hotspot name.

In an embodiment, the step 103 of acquiring an upgrade package broadcasted by the terminal device through a hotspot connection and upgrading according to the upgrade package includes:
receiving an upgrade package broadcasted by the terminal equipment through hotspot connection;
judging whether the upgrade patch is complete;
and if so, upgrading according to the upgrading packet.
In the embodiment of the application, whether the upgrade patch is complete or not can be judged so as to avoid subsequent upgrade errors. And if the upgrade package is not complete, the step of receiving the upgrade package broadcasted by the terminal equipment through the hotspot connection and the subsequent steps can be executed again. In some examples, it may also be determined whether the decrypted upgrade package is complete after the upgrade package is decrypted.
In an embodiment, after step 103 of acquiring an upgrade package broadcasted by the terminal device through a hotspot connection and upgrading according to the upgrade package, the method further includes:
and sending an upgrading result to the terminal equipment.
In this embodiment, the terminal device can acquire the upgrade condition of the vehicle-mounted device by sending the upgrade result to the terminal device, so as to determine whether to continue broadcasting the upgrade package and perform other operations. In addition, the upgrading result can also be sent to the terminal equipment after the upgrading success, so that the terminal equipment receiving the upgrading result reported by the vehicle-mounted equipment changes the relevant information of the vehicle-mounted equipment according to the upgrading condition of the vehicle-mounted equipment.
In a specific example, the specific step of acquiring the upgrade package by the vehicle-mounted device for upgrading may include the following steps:
step A1: a socket is initialized to receive data.
Step A2: and receiving the upgrade package.
Step A3: and decrypting the upgrade package to obtain upgrade data.
Step A4: if the upgrade data is complete data, perform step A5, otherwise perform step A2.
