[0002] With the popularization of the development of automobile intelligence, Internet of Vehicles services bring many conveniences.

[0003] For the IVI network part, the cloud service application interface only displays two states of remote connection and disconnection. When the vehicle is in a weak network state, the cloud service application cannot timely display the network status of the IVI, resulting in that the user cannot timely check the network status of the IVI.

[0004] The cloud service application depends on the network condition of the vehicle. When the vehicle is in a weak network state, the cloud service application cannot timely update the vehicle information, resulting in that the user cannot timely check and control the vehicle through the cloud service application. However, since the cloud service application displays that the IVI network is connected, the user will mistakenly think that the current IVI network is normal, and thus will generate related complaints about the use of the cloud service application. However, the actual situation is that the IVI network state is poor, and there is a bottleneck in the data interaction between the vehicle and the cloud. SUMMARY

[0028] In order to make the purposes, technical solutions and advantages of the present application more obvious, the following will describe the example embodiments according to the present application in detail with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present application.

[0029] First, referring to Figure 1 , the information display method 100 for implementing an embodiment of the present application is described. Figure 1 A schematic flowchart of the information display method 100 according to an embodiment of the present application is shown. As Figure 1 shown, the information display method 100 according to an embodiment of the present application can include the following steps:

[0030] In step S110, the in-vehicle infotainment network status is obtained from the cloud server, which is reported by the in-vehicle infotainment device to the cloud server.

[0031] In step S120, the network standard and network signal strength in which the in-vehicle infotainment device is located are determined based on the in-vehicle infotainment network status.

[0032] In step S130, the network mode and the network signal strength are displayed on the interface of the cloud service application of the terminal device.

[0033] In the embodiment of the present application, the cloud server obtains the network status of the vehicle machine from the vehicle machine, and the network status of the vehicle machine is reported to the cloud server by the vehicle machine. Through the connection between the terminal device and the cloud server, the cloud service application of the terminal device reads the network status of the vehicle machine on the cloud server, and determines the network mode and the network signal strength in which the vehicle machine is located based on the network status of the vehicle machine. Finally, the network mode and the network signal strength are displayed on the interface of the cloud service application of the terminal device, and the user can timely query the network mode and the network signal strength in which the vehicle machine is located on the cloud service application, so that the user can better use the cloud service application, improve the success rate of cloud control, and increase the confidence of the user in using the cloud service application.

[0034] In the embodiment of the present application, the network status of the vehicle machine in step S110 is obtained from the cloud server, and the network status of the vehicle machine is reported to the cloud server by the vehicle machine. The vehicle machine is wirelessly connected to the operator server through a base station, and the operator server is wirelessly connected to the cloud server, so that the vehicle machine is wirelessly connected to the cloud server. No matter the vehicle machine is in a driving state, a parking state or an off state, as long as the vehicle machine is in a connection state with the cloud server, the vehicle machine will actively report the network status to the cloud server.

[0035] The vehicle machine can be equipped with a subscriber identification module (SIM card) for networking, and different access point names (APNs) of different operators can be stored in the SIM card to ensure that the vehicle machine can be connected to the network. The vehicle machine can access the network in a private network mode, that is, the vehicle machine and the cloud server are connected through a private network. The operator can access the network through a private line or a virtual private network (VPN) to ensure that the network delay is small, the bandwidth is sufficient, the data transmission is stable and safe and reliable. APN1 is a private channel for accessing a private line opened by the vehicle machine manufacturer in the operator server. In an embodiment, the APN1 channel connects the vehicle machine and the operator server, and when the APN1 channel state shows success, the vehicle machine is connected to the operator server, and the operator server is wirelessly connected to the cloud server, so that the vehicle machine is wirelessly connected to the cloud server; when the APN1 channel state shows failure, the vehicle machine is disconnected from the operator server, so that the vehicle machine is disconnected from the cloud server.

[0036] In the embodiments of the present application, the network system and network signal strength in which the car machine is located are determined based on the car machine network state in step S120, comprising: determining the network system and network signal strength in which the car machine is located according to a specific network signal classification standard based on the car machine network state. The traditional car machine network state only displays that the remote connection is connected or not connected, and the user cannot further confirm the network system and network signal strength in which the car machine is located in the connection state. Therefore, according to the specific network signal classification standard, the network system and network signal strength in which the car machine is located are determined.

[0037] The network system is a signal transmission standard, mainly including 1G, 2G, 3G, 4G and 5G. The definitions of 1G, 2G, 3G, 4G and 5G are mainly given from the rate, service type, transmission delay, and various switching success rate angles to give different specific implementation technologies. G refers to Generation, that is, the meaning of "generation". Therefore, 1G means the first generation of mobile communication system, and 2G, 3G, 4G and 5G refer to the second, third, fourth and fifth generation of mobile communication system respectively. The network signal strength is mainly reflected in the number of network signal grids. The principle of network signal grid is that the car machine reports the detected signal condition to the network, and the network will select the technology, frequency band, channel and the like used by the car machine for the next communication. The network signal grid represents the signal strength, but the car machine network signal grid has no standard measurement unit. How the car machine "reports" the relevant information to the base station, and the signal grid number displayed for a specific signal strength depends on the car machine itself. Therefore, the car machine determines the network system and network signal strength in which the car machine is located according to a specific network signal classification standard.

[0038] In one embodiment, the car machine network state includes network signal quality, that is, the cloud service application interface can not only display that the car machine network is connected or not connected, but also determine the network signal quality in which the car machine is located. Based on the car machine network state, the network system and network signal strength in which the car machine is located are determined according to a specific network signal classification standard, comprising: determining the received power and signal-to-noise ratio of the network signal of the car machine based on the network signal quality; dividing the network signal of the car machine into a specific level based on the received power and the signal-to-noise ratio to obtain the network system and network signal strength in which the car machine is located.

[0039] Reference Signal Receiving Power (RSRP) is a key parameter that can represent the strength of wireless signals in a Long Term Evolution (LTE) network and one of the physical layer measurement requirements. It is the average value of the received signal power on all resource elements (REs) carrying reference signals within a certain symbol. The value range of RSRP is (-44, -140), and the larger the value, the stronger the signal. Signal to Interference plus Noise Ratio (SINR) is the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). It can be simply understood as "signal-to-noise ratio". SINR reflects the link quality of the current channel, and the larger the value, the stronger the signal.

[0040] In one embodiment, taking the 4G network standard as an example, the network strength can be divided into signal strength 4, 3, 2, 1 and no signal according to the size of the reference signal receiving power and the signal-to-noise ratio. The classification standard of network signal strength is:

[0041] When the value range of RSRP is -44dBm≥RSRP≥-85dBm, and the value range of SINR is SINR≥15dB, the network signal strength is 4;

[0042] When the value range of RSRP is -85dBm>RSRP≥-105dBm, and the value range of SINR is 15dB>SINR≥10dB, the network signal strength is 3;

[0043] When the value range of RSRP is -105dBm>RSRP≥-115dBm, and the value range of SINR is 10dB>SINR≥0dB, the network signal strength is 2;

[0044] When the value range of RSRP is -115dBm>RSRP≥-130dBm, and the value range of SINR is 0dB>SINR>-5dB, the network signal strength is 1;

[0045] When the value range of RSRP is -130dBm>RSRP, or the value range of SINR is -5>SINR, the network signal strength is no signal.

[0046] If only one of the RSRP and SINR conditions is met, the network signal strength will automatically decrease by one bar. For example, if the vehicle's infotainment system reports an RSRP of -80dBm and a SINR of 12dB for the 4G signal to the cloud server at a certain moment, the cloud service application will display the vehicle's signal strength as three bars. Similarly, there are specific standards for distinguishing network signal strength in 5G and 2G networks, which will not be elaborated here.

[0047] In the embodiments of this application, in step S130, the network standard and network signal strength are displayed on the interface of the cloud service application on the terminal device. The network standard is displayed as 2G, 3G, 4G, or 5G, and the network signal strength is displayed as 4 bars, 3 bars, 2 bars, 1 bar, or no signal. When the cloud service application interface displays a 5G network standard and a 2-bar network signal strength, the vehicle network signal strength is stronger than that of a 2G network standard and a 2-bar network signal strength.

[0048] In the embodiments of this application, the network standard displayed on the interface is interactive. Interaction, or communication and interaction, is a functional state that many internet platforms strive to create. Through an internet platform with interactive functions, users can not only obtain relevant information, news, or services, but also communicate and interact with each other or with the platform, thereby generating more creativity, ideas, and needs. In one embodiment, when a user's interactive operation on the network standard is received, a first prompt message is displayed on the interface. The first prompt message is used to guide the user on the correct cloud service operation method under the current network standard. After observing the network standard and network signal strength of the vehicle's infotainment system, the user can click on the network standard on the cloud service application interface to query the user's operation instructions for the cloud service application at the current location, which can improve the success rate of cloud control and increase the user's confidence in using the cloud service application.

[0049] In an embodiment of this application, when the network standard is 2G, the first prompt message includes: Under the current network standard, the vehicle needs approximately 30 seconds to successfully unlock via cloud service. Please wait patiently and do not press the unlock button repeatedly. After seeing the first prompt message on the cloud service application, the user understands that under the current vehicle network conditions, they need to wait patiently for the vehicle to unlock, preventing the user from frantically pressing the unlock button and avoiding the user's anxiety that the cloud service application has encountered an error.

[0050] In this embodiment, when the network standard and signal strength are insufficient to support cloud services, a second prompt message is displayed on the interface. This second prompt message prompts the user to change the vehicle's parking location so that the network standard and signal strength of the vehicle's infotainment system can support cloud services. If the network signal of the infotainment system is poor or disconnected at the current parking location, the cloud service application will display the second prompt message after the vehicle is turned off to remind the user to find a parking spot with a better network signal, facilitating the use of the cloud service application.

[0051] In one embodiment, when the vehicle's infotainment network is disconnected, the cloud service application cannot update the vehicle's status in a timely manner. When a user retrieves the vehicle's status through the cloud service application, they believe they are seeing the vehicle's current status, but in reality, they are seeing the status from when the network was last connected. For example, the car may be in location A, but the cloud service application shows it as being in location B; the windows may be closed, but the cloud service application shows they are open; even when the vehicle's network is disconnected, the user may repeatedly press the cloud service application to lock the car—in these situations, the cloud control system will fail. Displaying the vehicle's network status through the cloud service application solves these problems. Users can understand that the inaccurate vehicle status displayed by the cloud service application after the network disconnection is due to a problem with the vehicle's network, thus reducing user complaints about the cloud service application.

[0052] Therefore, the information display method according to this application embodiment connects the vehicle-mounted system and the cloud server, enabling the cloud server to obtain the vehicle-mounted system's network status from the vehicle-mounted system, which is reported by the vehicle-mounted system to the cloud server. Through the connection between the terminal device and the cloud server, the cloud service application on the terminal device reads the vehicle-mounted system's network status from the cloud server and determines the network type and signal strength of the vehicle-mounted system based on this status. Finally, the network type and signal strength are displayed on the interface of the cloud service application on the terminal device, allowing users to promptly query the network type and signal strength of the vehicle-mounted system through the cloud service application. This allows users to better utilize the cloud service application and improves the success rate of cloud control.

[0053] Below, refer to Figure 2 This describes an information reporting method 200 for implementing another embodiment of the present invention. Figure 2 A schematic flowchart of an information reporting method 200 according to an embodiment of this application is shown. Figure 2 As shown, the information reporting method 200 according to an embodiment of this application may include the following steps:

[0054] In step S210, it is determined whether the vehicle-mounted system and the cloud server have successfully connected.

[0055] In step S220, if the vehicle-mounted unit successfully connects to the cloud server, the vehicle-mounted unit's network status is reported to the cloud server so that the terminal devices in the cloud service system can execute the above-mentioned information display method.

[0056] In the embodiments of this application, the vehicle-mounted infotainment system (V2X) reports its network status to the cloud server via a connection between the V2X and the cloud server. Through the connection between the terminal device in the cloud service system and the cloud server, the terminal device can obtain the V2X network status from the cloud server and execute the aforementioned information display method.

[0057] In this embodiment, step S210 involves determining whether the vehicle-mounted unit (VMU) and the cloud server are successfully connected. The VMU connects wirelessly to the operator's server via a base station, and the operator's server connects wirelessly to the cloud server, thus enabling a wireless connection between the VMU and the cloud server. However, when the VMU is in an area with poor signal, the wireless connection between the VMU and the base station may be lost, causing the VMU to disconnect from the cloud server. In this case, it is necessary to determine the connection status between the VMU and the cloud server. The APN1 path connects the VMU and the operator's server. When the APN1 path status shows success, the VMU maintains a connection with the operator's server, and the operator's server wirelessly connects to the cloud server, thus determining that the VMU and the cloud server are wirelessly connected. When the APN1 path status shows failure, the VMU disconnects from the operator's server, thus determining that the VMU has disconnected from the cloud server. In this embodiment, when the APN1 path status shows failure, the VMU will determine whether the cloud server was connected at the previous moment. If it was connected, it will actively disconnect from the cloud server, and the cloud service application interface will display "No Network".

[0058] In the embodiments of this application, in step S220, after the vehicle-mounted system successfully connects to the cloud server, the vehicle-mounted system's network status is reported to the cloud server, enabling the terminal devices in the cloud service system to execute the aforementioned information display method. After the vehicle-mounted system reports its network status to the cloud server via the APN1 channel, the cloud server synchronizes the vehicle-mounted system's network status to the vehicle networking platform. The terminal devices, through their connection to the cloud server, obtain the vehicle-mounted system's network status on the vehicle networking platform and, according to specific network signal classification standards, promptly update the vehicle-mounted system's network standard and signal strength for user convenience.

[0059] In the embodiments of this application, the vehicle-mounted system reports its network status to the cloud server when the vehicle is in motion, parked, or turned off. Therefore, regardless of the vehicle's state, users can promptly check the vehicle's status through cloud service applications and remotely control the vehicle, diversifying cloud service application scenarios and making it more convenient for users to use the vehicle in different states.

[0060] In the embodiments of this application, the vehicle-mounted infotainment system reports its network status to the cloud server at different time intervals and / or different reporting methods depending on the vehicle's state. Alerting the user with varying frequencies based on the vehicle's location can reduce the system's power consumption. When the vehicle is in motion, its location changes significantly, leading to substantial changes in its network status. In this case, frequent reporting of the network status is less meaningful, and since the user is driving, their interaction with cloud service applications is reduced, resulting in a longer reporting cycle. When the vehicle is off, the user is more likely to use cloud service applications to unlock the vehicle and check functions such as doors, windows, and air conditioning, thus requiring a shorter reporting cycle for the network status.

[0061] In an embodiment of this application, when the vehicle is off, the vehicle-mounted infotainment system reports its network status to the cloud server via timed heartbeat packets. A heartbeat packet is a user-defined command word that periodically notifies the client and server of their respective statuses, sent at regular intervals, similar to a heartbeat, hence the name. The vehicle-mounted infotainment system sends a default heartbeat packet to the cloud server within these intervals. This heartbeat packet is sent to the cloud server via the APN1 channel and contains the vehicle-mounted infotainment system's network status.

[0062] Therefore, according to the information reporting method of this application embodiment, it is determined whether the vehicle-mounted system and the cloud server are connected. If connected, the network status of the vehicle-mounted system is reported to the cloud server. Through the connection between the terminal device in the cloud service system and the cloud server, the terminal device can update the vehicle-mounted system network standard and signal strength in a timely manner according to a specific network signal classification standard, which is convenient for users.

[0063] The following is combined Figure 3 The terminal device 300 provided according to another aspect of this application is described.

[0066] Those skilled in the art can understand the structure and specific operation of each module in the vehicle infotainment system 400 according to the embodiments of this application based on the foregoing description; for the sake of brevity, further details are omitted here. Therefore, the vehicle infotainment system according to the embodiments of this application wirelessly connects to a cloud server via a base station and reports the vehicle infotainment system's network status to the cloud server.

[0067] The following is combined Figure 5 Describes a cloud service system provided under another aspect of this application.

[0068] Those skilled in the art can understand the structure and specific operation of each module in the cloud service system 500 according to the embodiments of this application based on the foregoing description; for the sake of brevity, further details are omitted here. Therefore, the cloud service system according to the embodiments of this application interacts with the terminal device via the vehicle-mounted system, enabling the vehicle-mounted system to report its network status to the cloud server. The terminal device obtains the vehicle-mounted system's network status from the cloud server and displays the vehicle-mounted system's network type and signal type on the cloud service application's interface, facilitating the user's use of cloud control commands.

[0071] Based on the above description, the information display and reporting method and terminal device, vehicle-mounted system, and cloud service system of this application embodiment, through the connection between the vehicle-mounted system and the cloud server, enable the cloud server to obtain the vehicle-mounted system's network status from the vehicle-mounted system. This vehicle-mounted system's network status is reported to the cloud server by the vehicle-mounted system. Through the connection between the terminal device and the cloud server, the cloud service application on the terminal device reads the vehicle-mounted system's network status from the cloud server and determines the network type and signal strength of the vehicle-mounted system based on this status.
