[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0030] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis, and for parts not described in detail in one embodiment, reference can be made to the relevant description of other embodiments.

[0031] Tiantong Satellite and GNSS (Global Navigation Satellite System) are two different types of satellite systems with different functions, uses and technical principles.

[0032] The Tiantong satellite system is mainly used for satellite communications, providing voice, short message, data transmission and other services, similar to a "mobile satellite phone", and is suitable for areas without ground mobile communication networks (such as China Mobile, China Unicom, 4G / 5G, etc.), such as remote areas, oceans, plateaus, etc. GNSS (Global Navigation Satellite System) is mainly used to provide global positioning, navigation and timing services, mainly including four major systems: GPS of the United States, GLONASS of Russia, Galileo of Europe and Beidou of China, which are suitable for various scenarios on the ground and in the air, such as navigation positioning, traffic management, precision agriculture, etc.

[0033] The Tiantong satellite system solves communication problems and is mainly used for voice and data communications. It does not rely on ground base stations and can communicate globally. GNSS solves position, speed and time information problems and is mainly used for positioning and timing. It is widely used in map navigation, unmanned driving, surveying and mapping and other fields.

[0034] The Tiantong satellite system is based on geosynchronous orbit (GEO) satellites with a large coverage area. It is fixed above the Earth's equator. User terminals communicate directly with satellites without the need for support from ground base stations. GNSS satellites are distributed in medium and high orbits (such as GPS satellites in medium circular orbits at approximately 20,000 kilometers). User devices receive signals from multiple satellites to calculate specific locations.

[0035] The Tiantong satellite system is mainly used in scenarios that require satellite communications, such as navigation, aviation, rescue, military, outdoor exploration, and extreme environments without signal coverage (such as deep mountains, deserts, and open seas); GNSS is mainly used in car navigation, smartphone positioning, logistics tracking, geographic information systems, precision agriculture, etc.

[0036] Tiantong satellite solves the communication problem, and GNSS solves the location problem. The two can complement each other and be used in different scenarios.

[0037] In the existing technology, S-BOX is a vehicle-mounted mobile terminal based on the Tiantong satellite system. S-BOX can realize voice and SMS communication with ordinary 4G / 5G mobile phones and Tiantong satellite phones, and can also report vehicle-related information to the cloud control platform and other functions.

[0038] like Figure 1 and Figure 2 As shown in the figure, in the process of realizing the satellite communication system based on the car, Tiantong S-BOX is the core component of the solution, which includes MCU (microcontroller unit), dual-mode Bluetooth module, satellite communication module, positioning module and other modules, which are connected to MCU through UART interface. The solution promotes communication between various components, including communication between Tiantong satellite and cloud platform, communication between mobile terminal and Tiantong S-BOX, and communication between DMC and Tiantong S-BOX.

[0039] This implementation solution includes multiple communication connection methods, involving multiple communication links, including CAN / CANFD communication links, Bluetooth communication links, satellite communication links, ECU communication links and 4G / 5G terminal communication links. It can integrate satellite communication capabilities into the vehicle's existing control and communication infrastructure, enabling seamless data exchange between vehicle systems, mobile devices and satellite networks.

[0040] like Figure 3 As shown in the S-BOX block diagram, it includes an MCU chip (hereinafter referred to as MCU) ①, a power management chip ②, a Bluetooth chip ③, a GNSS module ④, a satellite communication modem module ⑤, a wiring harness with power and CAN lines, and an external Tiantong satellite antenna ⑥, a GNSS antenna ⑦ and a Bluetooth antenna ⑧.

[0041] Among them, the power management chip ② mainly supplies power to the MCU ①, Bluetooth chip ③, GNSS module ④ and satellite communication modem module ⑤ on the main board; MCU ① is mainly used to send and receive CAN messages to implement the power management strategy of SBOX, and communicates with the Bluetooth chip ③, GNSS module ④ and satellite communication modem module ⑤ through UART to realize data processing and forwarding; Bluetooth chip ③ mainly realizes Bluetooth communication with the smart cockpit domain control host on the whole vehicle, and communicates with the satellite communication modem module using PCM, and sends the call and text message content from the satellite communication modem module ⑤ to the smart cockpit domain control host through the Bluetooth protocol, and the smart cockpit domain control host then displays the text message content on the large screen, and the call content is played out by the whole vehicle speaker, and the Bluetooth chip ③ can obtain the voice of the driver and passengers from the smart cockpit domain control, and then send it to other mobile phones or car telematics service providers (Telematics Service Provider, TSP) through the satellite communication modem module ⑤; the satellite communication modem module ⑤ mainly sends and receives the audio and text message content of the call to realize the satellite communication function; the GNSS module ④ is mainly used to obtain the current vehicle location information.

[0042] However, the above implementation scheme is not conducive to the development trend of lightweight vehicles. It requires more wiring harnesses, chips and PCB motherboards, which will increase the cost of the whole vehicle, increase the complexity and failure rate of the system. The decentralized controllers will also increase the workload of software development and system integration accordingly, which is not conducive to subsequent upgrades and maintenance.

[0043] In the hardware architecture of the smart cockpit domain controller, the system-on-chip (SoC) is responsible for running complex operating systems and processing big data, such as unstructured data such as images, videos, and audio. The microcontroller unit (MCU) is mainly responsible for running the AUTOSAR system, which is used for CAN / LIN bus wake-up, communication, power management, power-on timing management, network management, diagnosis, vehicle data interaction and other functions. SoC and MCU work together to form a "SoC+MCU" design, which enables the smart cockpit domain controller to provide rich multimedia and interactive experience while meeting the strict requirements of automotive electronics for real-time and safety.

[0044] like Figure 4As shown, the first aspect of the present invention provides an intelligent cockpit domain controller with integrated satellite communication function, including: SoC, MCU1, power management chip (Power Supply) 2, WiFi Bluetooth chip (BT / Wi-Fi) 3, GNSS module (GNSS) 4 and satellite communication modem module 5 (Satellite Modem), the MCU1, WiFi Bluetooth chip (BT / Wi-Fi) 3, GNSS module (GNSS) 4 and satellite communication modem module 5 are respectively bidirectionally connected to the SoC, and the power management chip (PowerSupply) 2 is bidirectionally connected to the MCU1.

[0045] Please continue reading Figure 2 In the prior art, the overall vehicle communication solution for satellite communication function mainly includes four aspects: Tiantong satellite, Tiantong gateway, satellite cloud platform and vehicle environment. Among them, in the existing overall communication solution, the uplink and downlink communication link modes of voice and SMS are: Voice downlink communication link, that is, other satellite communication terminals or TSP transmit voice to the vehicle: Tiantong satellite → SBOX → vehicle machine → vehicle speaker; Voice uplink communication link, that is, the vehicle collects the voice of the people on the vehicle and sends it to other satellite terminals or TSP: microphone → vehicle → SBOX → Tiantong satellite; SMS downlink communication link, that is, sent from satellite to vehicle: satellite → SBOX → vehicle display; The SMS uplink communication link is when the vehicle edits the SMS and sends it to the satellite: edit the SMS on the vehicle → SBOX → satellite.

[0046] like Figure 3 and Figure 4 As shown, compared with the prior art, the present invention can save MCU① (corresponding to MCU1 in the present invention), power management chip ② (corresponding to power management chip (Power Supply) 2 in the present invention), Bluetooth chip ③ (corresponding to WiFi Bluetooth chip (BT / Wi-Fi) 3 in the present invention), GNSS module ④ (corresponding to GNSS module 4 in the present invention) and a PCB mainboard in the SBOX block diagram. The wiring harness that can be saved includes power lines of positive and negative power supplies, CAN bus, GNSS antenna and WiFi Bluetooth antenna, which reduces the wiring harness cost and module cost, and can achieve system integration, lightweight and low cost while ensuring satellite communication functions, so as to meet the higher requirements of modern automobile design for communication systems.

[0047] In the overall communication scheme of the present invention, the uplink and downlink communication link modes of voice and text messages are: Voice downlink communication link, that is, from Tiantong satellite → satellite communication modem module → SoC → vehicle speaker (amplifier connected to speaker); Voice uplink communication link, i.e. microphone → SoC → satellite communication modem module → Tiantong satellite; The SMS downlink communication link is from Tiantong satellite → satellite communication modem module → SoC → vehicle display (display screen); The SMS uplink communication link is from the vehicle display (display screen) → SoC → satellite communication modem module → Tiantong satellite.

[0048] Specifically, the microphone is controlled by the system-level chip to collect voice content; the display screen is controlled by the system-level chip to respond to the user's action of editing a text message and generate text message content; the power amplifier connected to the speaker is controlled by the system-level chip to directly play the processed voice content.

[0049] The satellite communication modem module is used to receive and send satellite signals transmitted from other satellite terminals or automobile remote service providers via the Tiantong satellite antenna, and convert the satellite signals into corresponding voice content and / or SMS content, and send them to the system-level chip; the system-level chip is used to receive and process the voice content and / or SMS content sent from the satellite communication modem module, and use the processed voice content for microphone playback, and / or use the processed SMS content for display screen display. The system-level chip is also used to receive and process the voice content collected by the microphone, and / or receive and process the SMS content generated by the display screen, and convert the processed voice content collected by the microphone and / or the generated SMS content into satellite signals via the satellite communication modem module and send them to other satellite terminals or automobile remote service providers.

[0050] The present invention can reduce the number of independent controllers and modules and achieve high system integration by integrating the satellite communication modem module into the smart cockpit domain controller. This integrated design can simplify the electronic architecture of the vehicle, reduce the use of wiring harnesses, chips and PCB motherboards, thereby reducing system complexity and failure rate. The integrated design can reduce physical connection points and interfaces, reduce the overall weight of the vehicle, improve the reliability and stability of the system, and also meet the development trend of lightweight vehicles; by reducing independent components and simplifying the system architecture, the cost of the whole vehicle can be reduced and the market competitiveness of the product can be improved; through the integrated design, the satellite communication function can work better with other functions of the smart cockpit, for example, satellite text messages can be directly displayed on the display screen, or satellite voice call content can be played through the vehicle audio system, thereby improving the user experience.

[0051] In one embodiment of the present invention, the display screen is also used to display the content of the short message processed by the system-level chip, and the specific content may include: SMS text: The display can present the SMS text content processed by the system-level chip, including sender information, receiving time and specific message content; Status information: The display screen can show the sending status, receiving status or reading status of SMS messages to help users understand the communication process; Location information: In some cases, such as with data provided by a GNSS module to the SoC, the display can show location information associated with the SMS, such as the geographic coordinates of the sender or receiver; Emergency alerts: For text messages sent in emergency situations, the display can highlight them in a special way, such as using different colors or flashing effects; Multimedia content: If supported by the satellite communication system, the display can show multimedia content such as simple images or icons; System prompts: The display can show system prompts related to SMS, such as insufficient storage space, signal strength, etc. Interactive options: The display screen can provide interactive options related to text messages, such as reply, forward, delete and other function buttons; Contact information: The display screen can show contact information related to the SMS sender, such as name, profile picture, etc. Timestamp: The display can show the specific time each SMS message was received or sent; Priority identification: For text messages of different priorities, the display screen can use different identifications to distinguish them.

[0052] Through these functions, the intelligent cockpit domain controller with integrated satellite communication function can provide users with a more intuitive and convenient SMS viewing and management experience, improving the practicality and user-friendliness of the in-vehicle communication system.

[0053] In one embodiment of the present invention, the intelligent cockpit domain controller with integrated satellite communication function further includes a microcontroller unit connected to the system-on-chip, which is used to diagnose the satellite communication modem module.

[0054] In this way, the satellite communication modem module can be diagnosed in real time, the reliability of the smart cockpit domain controller can be improved, potential problems can be discovered and solved in a timely manner, and the probability of failure can be reduced.

[0056] The power management chip can provide stable and efficient power supply for the smart cockpit domain controller.

[0057] In one embodiment of the present invention, the system-on-chip is also used to upgrade the satellite communication modem module.

[0058] SoCs usually have powerful computing capabilities and can process complex upgrade algorithms and large amounts of data more quickly. This high-performance processing capability can shorten upgrade time, improve upgrade efficiency, and support more complex upgrade operations. Upgrades can also fix potential security vulnerabilities, add new security features, and improve the system's ability to resist network attacks. It can also extend the service life of satellite communication modem modules and reduce the frequency of hardware replacement.

[0059] In one embodiment of the present invention, the intelligent cockpit domain controller with integrated satellite communication function further includes: a Tiantong satellite antenna connected to the satellite communication modem module, which is used to send and receive satellite signals.

[0060] The Tiantong satellite antenna connected to the satellite communication modem module can effectively send and receive satellite signals, especially in remote areas or areas where conventional mobile network coverage is insufficient. High-quality satellite communication can ensure that the vehicle can maintain contact with the outside world in various environments and improve driving safety.
