Description

Technical Field

[0001] This application relates to the field of vehicle networking technology, and in particular to an in-vehicle communication terminal, an in-vehicle communication system, and a vehicle. Background Technology

[0002] Currently, vehicle-mounted communication terminals are only equipped with traditional terrestrial wireless communication functions. In remote areas, deserts, Gobi, and other areas with insufficient network coverage, or during special periods (such as natural disasters), vehicles cannot use terrestrial communication networks and therefore cannot communicate with the outside world. Utility Model Content

[0003] This application provides an in-vehicle communication terminal, an in-vehicle communication system, and a vehicle to solve the problem that vehicles cannot communicate when terrestrial communication networks are unavailable.

[0004] According to a first aspect of the embodiments of this application, a vehicle-mounted communication terminal is provided, including a processing component and a satellite short message component; the satellite short message component is connected to the satellite communication terminal of the processing component; the satellite short message component has a built-in general-purpose integrated circuit card, and the general-purpose integrated circuit card contains a Beidou user identifier;

[0005] The processing component is used to receive communication information and send the communication information to the satellite short message component;

[0006] The satellite short message component is used to send the communication information and the BeiDou user identifier to the BeiDou satellite in the form of a short message; wherein, the communication information includes receiving device information and specific communication content; the BeiDou user identifier is used to uniquely identify the vehicle-mounted communication terminal in the BeiDou network.

[0007] Optionally, the vehicle-mounted communication terminal further includes a mobile communication module; the mobile communication module is connected to the mobile communication terminal of the processing component;

[0008] The processing component is also configured to receive an airbag deployment signal and, in response to the airbag deployment signal, send an emergency rescue command to the mobile communication module.

[0009] The mobile communication module is used to initiate an emergency call in response to the emergency rescue command, and after a preset number of emergency call failures, send emergency call failure feedback information to the processing component.

[0010] The processing component is also used to send a distress message to the satellite short message component after receiving the emergency call failure feedback information;

[0011] The satellite short message component is also used to send the distress message and the BeiDou user identifier to the BeiDou satellite in the form of a short message; wherein, the distress message includes rescue equipment information and preset distress content; the rescue equipment information includes at least one of the equipment information of the emergency contact person and the equipment information of the rescue platform.

[0012] In the event of an emergency when the vehicle is unable to use a terrestrial communication network, the airbags automatically deploy. In response to the airbag deployment signal, after the mobile communication module fails to make an emergency call, the processing component sends a distress message to the satellite short message component. Without manual operation by the occupants, the vehicle's communication terminal can automatically trigger the satellite short message component to send a distress message in response to the airbag deployment signal. Moreover, even when the vehicle is unable to use a terrestrial communication network and the mobile communication module fails to make an emergency call, the processing component can still send a distress message to the satellite short message component, triggering the satellite short message module component to send a distress message. This ensures that the distress message is sent to the rescue platform or emergency contacts in a timely and effective manner.

[0013] Optionally, the processing component includes a microcontroller unit and an application processor; the mobile communication module is connected to the mobile communication terminal of the microcontroller unit, the application control terminal of the microcontroller unit is connected to the application controlled terminal of the application processor, and the satellite communication terminal of the application processor is connected to the satellite short message component;

[0014] The microcontroller unit is used to receive the airbag deployment signal and, in response to the airbag deployment signal, send an emergency rescue command to the mobile communication module.

[0015] The mobile communication module is used to respond to the emergency rescue command, initiate an emergency call, and after a preset number of emergency call failures, send an emergency call failure feedback message to the microcontroller unit.

[0016] The microcontroller unit is also used to send a satellite distress command to the application processor after receiving the emergency call failure feedback information;

[0017] The application processor is configured to send the distress message to the satellite short message component in response to the satellite distress command.

[0018] In the event of an emergency when the vehicle cannot use a terrestrial communication network, the airbags deploy automatically without manual intervention from occupants. The onboard communication terminal responds to the airbag deployment signal, automatically triggering the satellite short message component to send a distress message. Even if the mobile communication module fails to make an emergency call when the vehicle cannot use a terrestrial communication network, the microcontroller unit and application processor can still trigger the satellite short message component to send a distress message, ensuring timely and effective delivery to rescue platforms or emergency contacts. Furthermore, the microcontroller unit sends commands to the mobile communication module and application processor, which in turn responds to the satellite distress command sent by the microcontroller unit and sends the distress message to the satellite short message component. The application processor does not need to be woken up while the microcontroller unit is operating, resulting in low power consumption and reducing the overall power consumption of the onboard communication terminal. Moreover, the application processor integrates multiple processors, supporting parallel data processing and improving the efficiency of distress message transmission.

[0019] Optionally, the vehicle-mounted communication terminal further includes an Ethernet component; the Ethernet component is connected to the Ethernet communication port of the processing component;

[0020] The Ethernet component is used to receive the communication information sent by the vehicle host and send the communication information to the processing component.

[0021] In situations where terrestrial communication networks are unavailable, the communication information entered by the user on the vehicle's onboard unit is sent to the Ethernet component. The Ethernet component then sends the communication information to the processing component, which in turn sends it to the satellite short message component. The satellite short message component then sends the communication information and the BeiDou user identifier to the BeiDou satellite in the form of a short message. This enables the communication information entered by the user on the vehicle's onboard unit to be sent out via satellite short messages through the cooperation of the vehicle's onboard unit and the Ethernet component, even when the vehicle cannot use terrestrial communication networks.

[0022] Optionally, the Ethernet component is further configured to receive a satellite short message function activation command sent by the vehicle-mounted host, and send the satellite short message function activation command to the processing component;

[0023] The processing component is further configured to send the satellite short message function activation command to the satellite short message component;

[0024] The satellite short message component is also used to start operation in response to the satellite short message function activation command.

[0025] The satellite short message component is generally in a turned-off state. Before using the satellite short message component to send a message, you need to start the satellite short message component. The satellite short message component is not always running, which can reduce the resource consumption of the vehicle communication terminal.

[0026] Optionally, the Ethernet component is further configured to receive a response information query instruction sent by the vehicle-mounted host, and send the response information query instruction to the processing component;

[0027] The processing component is also used to send the reply information query instruction to the satellite short message component;

[0028] The satellite short message component is also used to send the reply information query instruction to the BeiDou satellite in the form of a short message; wherein, the reply information query instruction is used to query the reply information of the receiving device corresponding to the communication information; receive the reply information of the receiving device sent by the BeiDou satellite, and send the reply information of the receiving device to the processing component;

[0029] The processing component is further configured to send the response information from the receiving device to the Ethernet component;

[0030] The Ethernet component is also used to send the reply information from the receiving device to the vehicle-mounted host.

[0031] When the vehicle-mounted communication terminal uses satellite short messages to send communication information, the Ethernet component receives the reply information query command sent by the vehicle host. The Ethernet component, processing component and satellite short message component work together to enable users to actively query the reply information of the receiving device corresponding to the communication information through the vehicle host, thereby improving the user experience and satisfaction.

[0032] Optionally, the vehicle-mounted communication terminal further includes a Bluetooth component; the Bluetooth component is connected to the Bluetooth communication terminal of the processing component;

[0033] The Bluetooth component is used to receive the communication information sent by the mobile device carried by the vehicle owner, and to send the communication information to the processing component.

[0034] In situations where terrestrial communication networks are unavailable, the vehicle owner inputs communication information on their mobile device. The device then transmits this information to a Bluetooth component, which in turn sends it to a processing component. This processing component then forwards the information to a satellite short message component, which in turn transmits the communication information and the BeiDou user identifier to the BeiDou satellite. This allows the communication information input on the vehicle's mobile device to be sent via satellite short message through the Bluetooth component, even when the vehicle cannot access terrestrial communication networks.

[0035] Optionally, the vehicle-mounted communication terminal further includes a wireless network component; the wireless network component is connected to the wireless network communication terminal of the processing component;

[0036] The wireless network component is used to receive the communication information sent by the mobile device carried by the vehicle owner, and send the communication information to the processing component.

[0037] In situations where terrestrial communication networks are unavailable, the vehicle owner inputs communication information on their mobile device. The device then sends this information to the wireless network component, which in turn sends it to the processing component. The processing component then forwards the information to the satellite short message component, which transmits the communication information and the BeiDou user identifier to the BeiDou satellite. This allows the communication information input on the vehicle's mobile device to be sent via satellite short messages through the wireless network component, even when the vehicle cannot access terrestrial communication networks.

[0038] According to a second aspect of the embodiments of this application, an in-vehicle communication system is provided, including an in-vehicle host and an in-vehicle communication terminal as described in the first aspect; the in-vehicle communication terminal further includes an Ethernet component; the in-vehicle host and the processing component are connected via the Ethernet component.

[0039] The vehicle-mounted host is used to send communication information to the Ethernet component;

[0040] The Ethernet component is used to receive the communication information sent by the vehicle host and send the communication information to the processing component.

[0041] According to a third aspect of the embodiments of this application, a vehicle is provided, including the vehicle communication system as described in the second aspect.

[0042] In this application, the vehicle-mounted communication terminal includes a processing component and a satellite short message component. When terrestrial communication networks are unavailable, the vehicle-mounted communication terminal can receive communication information through the processing component. The processing component then sends the communication information to the satellite short message component, which in turn sends the communication information and the BeiDou user identifier to the BeiDou satellite in the form of a short message. The communication information includes receiving device information and specific communication content, enabling communication using satellite short messages. Satellite short message communication offers advantages such as all-weather, wide-area coverage, and high reliability. The communication information is then sent to the BeiDou satellite, and BeiDou... The satellite then sends the specific communication content to the corresponding receiving device based on the receiving device information. Moreover, the satellite short message component has a built-in general-purpose integrated circuit card containing a BeiDou user identifier. The satellite short message component sends the BeiDou user identifier contained in the general-purpose integrated circuit card to the BeiDou satellite. The BeiDou user identifier is used to uniquely identify the vehicle-mounted communication terminal in the BeiDou network. There is no need for the vehicle-mounted communication terminal to register its identity information separately in the BeiDou network. When the receiving device receives the communication information, it can also know which vehicle-mounted communication terminal sent the communication information, thus improving the accuracy of the entire communication process. Furthermore, traditional Tiantong satellite communication requires support for real-time high data rate services such as voice and video, necessitating a wider bandwidth and placing higher demands on the transmission power and antenna size of vehicle-mounted communication terminals. In contrast, satellite short message communication is only used to transmit short messages, which contain fewer characters and have lower bandwidth requirements, allowing for low-power designs. This results in lower requirements on the transmission power and antenna size of vehicle-mounted communication terminals. Compared to traditional Tiantong satellite communication, using satellite short message communication in vehicles reduces the cost of these terminals, thus solving the problem of vehicles being unable to communicate when terrestrial communication networks are unavailable.

Detailed Implementation

[0055] Currently, vehicle-mounted communication terminals are only equipped with traditional terrestrial wireless communication functions. In remote areas, deserts, Gobi, and other areas with insufficient network coverage, or during special periods (such as natural disasters), vehicles cannot use terrestrial communication networks and therefore cannot communicate with the outside world.

[0056] Therefore, it is necessary to improve the vehicle-mounted communication terminal so that the vehicle can communicate even when it is unable to use the terrestrial communication network.

[0057] The inventors discovered that because traditional Tiantong satellite communication needs to support real-time high data rate services such as voice and video, it requires a wider frequency band. It also needs to increase the transmission power to ensure that the signal maintains sufficient strength in the wide frequency band to resist free space loss and atmospheric attenuation. In addition, it requires a larger aperture antenna to provide high gain and reduce the beamwidth, thereby focusing energy in the wide frequency band. Therefore, traditional Tiantong satellite communication has higher requirements for the transmission power and antenna size of vehicle-mounted communication terminals, resulting in higher overall product costs and higher requirements for the usage environment, which is not conducive to mass production and vehicle installation.

[0058] Therefore, the inventors considered that in situations where terrestrial communication networks are unavailable, vehicle-mounted communication terminals can use satellite short message service to address the problem of vehicles being unable to communicate when terrestrial communication networks are unavailable. Furthermore, satellite short message service is only used for transmitting short text messages, which have lower bandwidth requirements, allowing for low-power designs and lower requirements on the transmission power and antenna size of the vehicle-mounted communication terminal. Compared to traditional Tiantong satellite communication, the cost of vehicle-mounted communication terminals using satellite short message service is also lower. It is more cost-effective than Tiantong satellite communication solutions, more suitable for vehicle installation, and applicable to emergency communication in special scenarios. The following embodiments detail this solution.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] Exemplary vehicle-mounted communication terminal

[0061] Please see Figure 1 In one exemplary embodiment, a vehicle-mounted communication terminal is provided. For example... Figure 1 As shown, the vehicle-mounted communication terminal includes a processing component 100 and a satellite short message component 200; the satellite short message component 200 is connected to the satellite communication end of the processing component 100; the satellite short message component 200 has a built-in general-purpose integrated circuit card, which contains a Beidou user identifier;

[0062] Processing component 100 is used to receive communication information and send the communication information to satellite short message component 200;

[0063] The satellite short message component 200 is used to send communication information and BeiDou user identifier to the BeiDou satellite in the form of short messages; the communication information includes receiving device information and specific communication content; the BeiDou user identifier is used to uniquely identify the vehicle-mounted communication terminal in the BeiDou network.

[0064] In an exemplary embodiment, the processing component 100 may include an MCU (Microcontroller Unit), or an MCU and an AP (Application Processor), or other processing components; this application does not limit this.

[0065] In the exemplary embodiment, the communication information includes receiving device information and specific communication content. The receiving device information may include the recipient's mobile phone number, the identifier of the terminal device carried by the recipient, or other receiving device information. As long as the communication information can be sent to the receiving device based on the receiving device information, this application does not impose any limitations on this.

[0066] In the exemplary embodiment, the universal integrated circuit card refers to the UICC (Universal Integrated Circuit Card). The UICC contains a BeiDou user identifier, which is used to uniquely identify the vehicle-mounted communication terminal in the BeiDou network, eliminating the need for the vehicle-mounted communication terminal to register its identity information separately in the BeiDou network.

[0067] In an exemplary embodiment, the satellite short message component 200 can implement satellite short message service, using S / L band satellite transmission. In areas without terrestrial mobile communication network signals, the satellite short message component 200 provides a reliable communication means. Satellite short message refers to a technology that enables direct two-way information transmission between a satellite positioning terminal and a BeiDou satellite or BeiDou ground service station via satellite signals. The S-band refers to the radio wave band with frequencies between 2 and 4 GHz, and the S-BAND antenna is an antenna used for wireless communication in this band. The L-band refers to the radio wave band with frequencies between 1 and 2 GHz, and the L-BAND antenna is an antenna used for wireless communication in this band.

[0068] In an exemplary embodiment, after the user manually or the vehicle automatically activates the satellite short message function, the vehicle-mounted communication terminal sends the communication information and the BeiDou user identifier to the BeiDou satellite in the form of a short message. The BeiDou satellite then sends the communication information and the BeiDou user identifier to the BeiDou short message service platform. The BeiDou short message service platform then sends the communication information to the vehicle cloud platform to which the BeiDou user identifier belongs. The vehicle cloud platform forwards the communication information to the recipient's mobile phone or other receiving device via mobile internet, mobile phone text message (industry text message), etc., according to actual business needs.

[0069] In the exemplary embodiment, the TSP (Telematics Service Provider) system in the vehicle-cloud platform binds the vehicle identification number (VIN) and other unique vehicle identification information with the BeiDou user identifier in the built-in universal integrated circuit card of the satellite short message component 200, and also binds it with the vehicle owner's identity information (such as a mobile phone number), thus completing user real-name management. During the vehicle's use of BeiDou satellite communication services, the BeiDou network only authenticates the BeiDou user identifier in the built-in universal integrated circuit card of the satellite short message component 200, without requiring any other authentication information.

[0070] In the exemplary embodiment, after the BeiDou satellite successfully sends the communication information and BeiDou user identifier to the BeiDou short message service platform, the BeiDou short message service platform sends a communication receipt to the BeiDou satellite, and the BeiDou satellite sends the communication receipt to the vehicle-mounted communication terminal to realize the reception of the communication receipt.

[0071] In this application, the vehicle-mounted communication terminal includes a processing component and a satellite short message component. When terrestrial communication networks are unavailable, the vehicle-mounted communication terminal can receive communication information through the processing component. The processing component then sends the communication information to the satellite short message component, which in turn sends the communication information and the BeiDou user identifier to the BeiDou satellite in the form of a short message. The communication information includes receiving device information and specific communication content, enabling communication using satellite short messages. Satellite short message communication offers advantages such as all-weather, wide-area coverage, and high reliability. The communication information is then sent to the BeiDou satellite, and BeiDou... The satellite then sends the specific communication content to the corresponding receiving device based on the receiving device information. Moreover, the satellite short message component has a built-in general-purpose integrated circuit card containing a BeiDou user identifier. The satellite short message component sends the BeiDou user identifier contained in the general-purpose integrated circuit card to the BeiDou satellite. The BeiDou user identifier is used to uniquely identify the vehicle-mounted communication terminal in the BeiDou network. There is no need for the vehicle-mounted communication terminal to register its identity information separately in the BeiDou network. When the receiving device receives the communication information, it can also know which vehicle-mounted communication terminal sent the communication information, thus improving the accuracy of the entire communication process. Furthermore, traditional Tiantong satellite communication requires support for real-time high data rate services such as voice and video, necessitating a wider bandwidth and placing higher demands on the transmission power and antenna size of vehicle-mounted communication terminals. In contrast, satellite short message communication is only used to transmit short messages, which contain fewer characters and have lower bandwidth requirements, allowing for low-power designs. This results in lower requirements on the transmission power and antenna size of vehicle-mounted communication terminals. Compared to traditional Tiantong satellite communication, using satellite short message communication in vehicles reduces the cost of these terminals, thus solving the problem of vehicles being unable to communicate when terrestrial communication networks are unavailable.

[0072] To ensure timely and effective transmission of distress messages to rescue platforms or emergency contacts in the event of a vehicle emergency when terrestrial communication networks are unavailable, the following embodiments propose a scheme for automatically triggering a satellite short message component to send distress messages when a vehicle experiences an emergency. In some embodiments, such as Figure 2As shown, the vehicle-mounted communication terminal includes a processing component 100, a satellite short message component 200, and a mobile communication module 300; the satellite short message component 200 is connected to the satellite communication terminal of the processing component 100; the mobile communication module 300 is connected to the mobile communication terminal of the processing component 100; the satellite short message component 200 has a built-in general-purpose integrated circuit card, which contains a Beidou user identifier.

[0073] The processing component 100 is also used to receive the airbag deployment signal and, in response to the airbag deployment signal, send an emergency rescue command to the mobile communication module 300.

[0074] The mobile communication module 300 is used to initiate an emergency call in response to an emergency rescue command, and after a preset number of emergency call failures, it sends an emergency call failure feedback message to the processing component 100.

[0075] The processing component 100 is also used to send a distress message to the satellite short message component 200 after receiving feedback information of an emergency call failure;

[0076] The satellite short message component 200 is also used to send distress information and BeiDou user identifiers to the BeiDou satellite in the form of short messages; wherein, the distress information includes rescue equipment information and preset distress content; the rescue equipment information includes at least one of the equipment information of the emergency contact person and the equipment information of the rescue platform.

[0077] In an exemplary embodiment, the processing component 100 receives an airbag deployment signal and, in response, sends an emergency rescue command to the mobile communication module 300. This can be achieved by connecting a sensor and a pin of the processing component 100. When the sensor sends the airbag deployment signal to the processing component 100, the voltage level of the pin connecting the processing component 100 and the sensor changes, for example, from low to high. After processing by the internal circuitry of the processing component 100, the voltage level of the pin connecting the processing component 100 and the mobile communication module 300 also changes, for example, from low to high. With the voltage level of the pin connecting the processing component 100 and the mobile communication module 300 high, the processing component 100 sends an emergency rescue command to the mobile communication module 300. The processing component 100 only performs signal interaction, which can be implemented through its internal circuitry. Similarly, all processing components 100 described herein only perform signal interaction, which can be implemented through their internal circuitry, and will not be elaborated further.

[0078] When a vehicle collision occurs, the airbags deploy. The processing component 100 receives the airbag deployment signal from the sensor and, in response, sends an emergency rescue command to the mobile communication module 300. This command instructs the mobile communication module 300 to initiate an emergency call (e-call). The mobile communication module 300 responds to the command and initiates the emergency call. If the emergency call is successful, a preset distress message is sent directly to the rescue equipment via the mobile communication module 300. If the emergency call fails, the mobile communication module 300 will re-initiate the emergency call. After a preset number of failed emergency calls, the mobile communication module 300 sends an emergency call failure feedback message to the processing component 100. The processing component 100 then sends a distress message to the satellite short message component 200. The system sends a distress message and the BeiDou user identifier to the BeiDou satellite in the form of a short message. In the event of an emergency when the vehicle cannot use the terrestrial communication network, the airbags will automatically deploy. In response to the airbag deployment signal, after the emergency call from the mobile communication module 300 fails, the processing component 100 sends a distress message to the satellite short message component 200. No manual operation is required from the people in the vehicle. The vehicle communication terminal can automatically trigger the satellite short message component to send a distress message in response to the airbag deployment signal. Moreover, even when the vehicle cannot use the terrestrial communication network and the emergency call from the mobile communication module 300 fails, the processing component 100 can still send a distress message to the satellite short message component 200, triggering the satellite short message module component to send a distress message. This can promptly and effectively send the distress message to the rescue platform or emergency contacts.

[0079] The vehicle-mounted communication terminal integrates a satellite short message component 200 and a mobile communication module 300, achieving complementary advantages of the two communication technologies. It utilizes the high speed, large capacity, and wide coverage of mobile communication, while leveraging the advantages of satellite short message communication, such as all-weather, wide coverage, and high reliability.

[0080] In an exemplary embodiment, the mobile communication module 300 may include a 5G communication module, a 5G+V2X (Vehicle to Everything) communication module, or a 2G, 3G, or 4G communication module, etc., and this application does not limit this. Traditional vehicle-to-everything (V2X) services such as 5G, positioning, vehicle-to-everything (V2X) communication, and OTA (Over-the-Air Technology) operate in the mobile communication module 300. When the mobile communication module 300 includes a 5G+V2X communication module, it supports 5G network communication and V2X functionality, enabling high-speed data transmission and possessing characteristics such as high reliability and low latency.

[0081] In an exemplary embodiment, the rescue equipment information includes at least one of the emergency contact's equipment information and the rescue platform's equipment information. It may include only the emergency contact's equipment information, only the rescue platform's equipment information, or both; this application does not limit this. The emergency contact's equipment information may be the emergency contact's mobile phone number, the identifier of the terminal device carried by the emergency contact, or other equipment information of the emergency contact. The rescue platform's equipment information may refer to the rescue platform's phone number or the rescue platform's equipment identifier; this application does not limit this.

[0082] In some embodiments, the processing component 100 includes a microcontroller unit and an application processor. The following embodiments detail a scheme in which the microcontroller unit and the application processor work together to automatically trigger a satellite short message component to send a distress message when a vehicle encounters an emergency. In some embodiments, such as Figure 3 As shown, the vehicle-mounted communication terminal includes a processing component 100, a satellite short message component 200, and a mobile communication module 300; the processing component 100 includes a microcontroller unit 110 and an application processor 120; the mobile communication module 300 is connected to the mobile communication terminal of the microcontroller unit 110, the application control terminal of the microcontroller unit 110 is connected to the application controlled terminal of the application processor 120, and the satellite communication terminal of the application processor 120 is connected to the satellite short message component 200; the satellite short message component 200 has a built-in general-purpose integrated circuit card, which contains a Beidou user identifier;

[0083] The microcontroller unit 110 is used to receive the airbag deployment signal and, in response to the airbag deployment signal, send an emergency rescue command to the mobile communication module 300.

[0084] The mobile communication module 300 is used to initiate an emergency call in response to an emergency rescue command, and after a preset number of emergency call failures, it sends an emergency call failure feedback message to the microcontroller unit 110.

[0085] The microcontroller unit 110 is also used to send a satellite distress command to the application processor 120 after receiving emergency call failure feedback information;

[0086] Application processor 120 is used to send distress information to satellite short message component 200 in response to a satellite distress command;

[0087] The satellite short message component 200 is also used to send distress information and BeiDou user identifiers to the BeiDou satellite; wherein, the distress information includes rescue equipment information and preset distress content; the rescue equipment information includes at least one of the equipment information of the emergency contact person and the equipment information of the rescue platform.

[0088] In the exemplary embodiment, the microcontroller unit 110 is responsible for sending commands, internal data processing and control, and implementing services including backup battery management, CAN (Controller Area Network) communication, network management, and diagnostics. An external watchdog timer is used to enhance the reliability of the microcontroller unit 110. Communication must be maintained between the microcontroller unit 110 and the watchdog timer. If the watchdog timer does not receive a message from the microcontroller unit 110 for an extended period, it will restart the microcontroller unit 110. The microcontroller unit 110 also controls the power-on of various components in the vehicle communication terminal and restarts the corresponding components when no communication connection is detected with any component (e.g., the mobile communication module 300).

[0089] In the exemplary embodiment, the application processor 120 can be a System on Chip (SoC), providing high computing power support. For example, the V2X protocol stack and application scenario algorithms run on the SoC. The SoC integrates multiple processors and various interfaces, responsible for data transmission and processing of the mobile communication module 300 and the satellite short message component 200. The interaction between the mobile communication module 300 and the application processor 120 is not particularly relevant to this embodiment, therefore... Figure 3 The connection between the mobile communication module 300 and the application processor 120 is not shown in the document. However, the mobile communication module 300 and the application processor 120 can be connected as needed, and this application does not impose any limitations on this. In this embodiment, the application processor 120 is primarily responsible for receiving satellite distress commands sent by the microcontroller unit 110 and, in response to the satellite distress commands, sending distress information to the satellite short message component 200.

[0090] In the exemplary embodiment, the application processor 120 provides high computing power support, supporting up to 80K DMIPS (Dhrystone Million Instructions Per Second, a metric for processor performance, representing the number of Dhrystone benchmark instructions that the processor can execute per second), which can meet the computing power needs for many years to come.

[0091] In the event of an emergency when the vehicle is unable to use a terrestrial communication network, the airbags automatically deploy. In response to the airbag deployment signal, after the emergency call from the mobile communication module 300 fails, the microcontroller unit 110 sends a satellite distress signal to the application processor 120. In response to the satellite distress signal, the application processor 120 sends a distress message to the satellite short message component 200. Without manual operation by the occupants, the vehicle communication terminal can automatically trigger the satellite short message component to send a distress message in response to the airbag deployment signal. Moreover, even when the vehicle is unable to use a terrestrial communication network and the emergency call from the mobile communication module 300 fails, the satellite short message component can still be triggered by the cooperation of the microcontroller unit 110 and the application processor 120 to send a distress message, enabling timely and effective delivery of the distress message to the rescue platform or emergency contacts. Furthermore, the microcontroller unit 110 and application processor 120 work together to automatically trigger the satellite short message component to send a distress message when an emergency occurs in the vehicle. The microcontroller unit 110 is responsible for sending instructions to the mobile communication module 300 and the application processor 120. The application processor 120 is responsible for responding to the satellite distress message instructions sent by the microcontroller unit 110 and sending the distress message to the satellite short message component 200. The application processor 120 does not need to be woken up while the microcontroller unit 110 is operating, resulting in low power consumption for the microcontroller unit 110 and reducing the overall power consumption of the vehicle communication terminal. Moreover, the application processor 120 integrates multiple processors, supporting parallel data processing and improving the efficiency of distress message transmission.

[0092] To transmit communication information entered by the user on the in-vehicle host when the vehicle cannot use a terrestrial communication network, the following embodiments propose a scheme that uses the in-vehicle host and an Ethernet component to transmit the communication information entered by the user on the in-vehicle host via satellite short messages. In some embodiments, such as Figure 4 As shown, the vehicle-mounted communication terminal includes a processing component 100, a satellite short message component 200, and an Ethernet component 400; the satellite short message component 200 is connected to the satellite communication end of the processing component 100; the Ethernet component 400 is connected to the Ethernet communication end of the processing component 100; the satellite short message component 200 has a built-in general-purpose integrated circuit card, which contains a Beidou user identifier.

[0093] Ethernet component 400 is used to receive communication information sent by the vehicle host and send the communication information to processing component 100;

[0094] Processing component 100 is used to receive communication information and send the communication information to satellite short message component 200;

[0095] The satellite short message component 200 is used to send communication information and BeiDou user identifier to the BeiDou satellite in the form of short messages; the communication information includes receiving device information and specific communication content; the BeiDou user identifier is used to uniquely identify the vehicle-mounted communication terminal in the BeiDou network.

[0096] In an exemplary embodiment, the vehicle-mounted host can refer to the HUT (host), a device including a vehicle-mounted display screen.

[0097] In an exemplary embodiment, the Ethernet component 400 receives communication information sent by the vehicle host. This can be achieved by the user manually inputting communication information on the vehicle display screen in the vehicle host, and the vehicle host sending the manually input communication information to the Ethernet component 400; or by the vehicle host receiving the user's voice signal, identifying the communication information from the user's voice signal, and sending the communication information to the Ethernet component 400; or by other methods, which are not limited in this application.

[0098] In the exemplary embodiment, Ethernet component 400 provides high-speed data transmission and communication for Ethernet interconnection with external devices. Considering that 5G downlink speeds will exceed 1000 Mbps, Ethernet component 400 can adopt a Gigabit Ethernet design to achieve high-speed data transmission and communication.

[0099] In an exemplary embodiment, the Ethernet component 400 may include a Gigabit Ethernet PHY (Physical Layer) and Gigabit Ethernet ports. The Ethernet component 400 may include multiple Gigabit Ethernet PHYs and Gigabit Ethernet ports. For example, a first Gigabit Ethernet PHY is connected between the processing component 100 and a first Gigabit Ethernet port, and the first Gigabit Ethernet port is connected between the first Gigabit Ethernet PHY and the vehicle host (which may refer to a cockpit domain controller). A second Gigabit Ethernet PHY is connected between the processing component 100 and a second Gigabit Ethernet port, and the second Gigabit Ethernet port is connected between the second Gigabit Ethernet PHY and the intelligent driving domain controller, supporting two Gigabit vehicle Ethernet connections to the corresponding cockpit domain controller and intelligent driving domain controller. This application does not limit this; the Ethernet component 400 may also include other numbers of Gigabit Ethernet PHYs and Gigabit Ethernet ports.

[0100] In situations where terrestrial communication networks are unavailable, the communication information entered by the user on the vehicle's onboard unit is sent to the Ethernet component. The Ethernet component then sends the communication information to the processing component, which in turn sends it to the satellite short message component. The satellite short message component then sends the communication information and the BeiDou user identifier to the BeiDou satellite in the form of a short message. This enables the communication information entered by the user on the vehicle's onboard unit to be sent out via satellite short messages through the cooperation of the vehicle's onboard unit and the Ethernet component, even when the vehicle cannot use terrestrial communication networks.

[0101] To reduce resource consumption of the vehicle-mounted communication terminal, the satellite short message component 200 is not always operational. Before sending messages, it is necessary to start the satellite short message component 200. The following embodiments describe specific schemes for controlling the start-up of the satellite short message component 200. In some embodiments, the Ethernet component 400 is also used to receive a satellite short message function start command sent by the vehicle-mounted host and send the satellite short message function start command to the processing component 100;

[0102] The processing component 100 is also used to send the satellite short message function activation command to the satellite short message component 200;

[0103] The satellite short message component 200 is also used to start operation in response to the satellite short message function activation command.

[0104] In an exemplary embodiment, the vehicle-mounted host has a button on its in-vehicle display screen to activate the satellite short message function. After the user clicks the button, the in-vehicle host sends a satellite short message function activation command to the Ethernet component 400. The Ethernet component 400 then sends the command to the processing component 100, which in turn sends it to the satellite short message component 200. The satellite short message component 200 starts operating in response to the command and begins satellite acquisition. Once satellite acquisition is successful, an interface for sending communication information is displayed on the in-vehicle display screen. The user inputs specific communication information, which is then sent out via the Ethernet component 400, the processing component 100, and the satellite short message component 200.

[0105] The satellite short message component 200 is generally in a turned-off state. Before using the satellite short message component 200 to send a message, the satellite short message component 200 should be started and running. The satellite short message component 200 is not always running, which can reduce the resource consumption of the vehicle communication terminal.

[0106] When a vehicle-mounted communication terminal uses satellite short messages to send communication information, sometimes users want to actively query the corresponding receiving device for a reply through the vehicle-mounted host. The following embodiments describe a specific scheme for users to actively query the corresponding receiving device for a reply through the vehicle-mounted host. In some embodiments, the Ethernet component 400 is also used to receive a reply information query instruction sent by the vehicle-mounted host and send the reply information query instruction to the processing component 100;

[0107] The processing component 100 is also used to send the reply information query command to the satellite short message component 200;

[0110] The Ethernet component 400 is also used to send the response information from the receiving device to the vehicle host.

[0111] In the exemplary embodiment, after receiving communication information sent by the vehicle-mounted communication terminal, the receiving device can reply to the received communication information via mobile phone SMS or APP (Application). The reply information of the receiving device is sent to the vehicle cloud platform to which the Beidou user identifier belongs via the Internet or other means, and the reply information of the receiving device can be stored in the form of an email address.

[0112] In the exemplary embodiment, when a user initiates the reply information query function, the vehicle-mounted communication terminal sends a reply information query command to the BeiDou satellite. The BeiDou satellite then sends the reply information query command to the BeiDou Short Message Service Platform. The BeiDou Short Message Service Platform sends the reply information query command to the vehicle cloud platform to which the BeiDou user identifier belongs to query email information. The vehicle cloud platform to which the BeiDou user identifier belongs sends the reply information from the receiving device corresponding to the communication information to the BeiDou Short Message Service Platform. The BeiDou Short Message Service Platform then sends the reply information from the receiving device corresponding to the communication information to the BeiDou satellite. The BeiDou satellite then sends the reply information from the receiving device corresponding to the communication information to the vehicle-mounted communication terminal. The vehicle-mounted communication terminal then sends the reply information from the receiving device corresponding to the communication information to the vehicle-mounted host, thus realizing the reply receiving function.

[0113] In an exemplary embodiment, the vehicle-mounted host has a reply information query button on its in-vehicle display screen. After the user clicks the reply information query button, the in-vehicle host sends a reply information query command to the Ethernet component 400. The Ethernet component 400 sends the reply information query command to the processing component 100. The processing component 100 sends the reply information query command to the satellite short message component 200. The satellite short message component 200 sends the reply information query command to the BeiDou satellite. The reply information query command is used to query the reply information of the receiving device corresponding to the communication information. The BeiDou satellite sends the reply information of the receiving device to the satellite short message component 200. The satellite short message component 200 sends the reply information of the receiving device to the processing component 100. The processing component 100 sends the reply information of the receiving device to the Ethernet component 400. The Ethernet component 400 sends the reply information of the receiving device to the in-vehicle host, and the in-vehicle display screen in the in-vehicle host displays the reply information of the receiving device. When the vehicle-mounted communication terminal uses satellite short messages to send communication information, the Ethernet component 400 receives the reply information query command sent by the vehicle host. The Ethernet component 400, the processing component 100 and the satellite short message component 200 work together to enable users to actively query the reply information of the receiving device corresponding to the communication information through the vehicle host, thereby improving the user experience and satisfaction.
