[0024] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below, in which only the parts related to the embodiment of the present invention are shown.

[0025] like Figure 1 As shown, the present invention provides a V2X terminal with an onboard gateway, including an Ethernet connection link 1, a first microprocessor 2 connected to the Ethernet connection link 1, a second microprocessor 3 connected to the first microprocessor 2, a CAN connection link 4 connected to the second microprocessor 3, a LIN connection link 5 connected to the second microprocessor 3, and a V2X module 6 connected to the first microprocessor 2. Specifically, the CAN connection link 4 and the LIN connection link 5 are both connected to the vehicle body system.

[0026] The second microprocessor 3 receives body system message data from the CAN connection link 4 and the LIN connection link 5, and forwards the received body system message data to the first microprocessor 2. The first microprocessor 2 sends the received body system message data to the Ethernet connection link 1 and the V2X module 6, which then receive and transmit the data to the outside of the body system. The first microprocessor 2 also receives external body system message data via the Ethernet connection link 1 and the V2X module 6, and transmits the received external body system message data to the second microprocessor 3. The second microprocessor 3 forwards the received external body system message data to the CAN connection link 4 and the LIN connection link 5, which then transmit the data to the body system.

[0027] It should be noted that the external body system in this example refers to the smart terminal, road test unit, base station, etc. corresponding to the body system. Specifically, the external objects that the V2X module 6 interacts with include other body systems, roadside computing units (RSUs), positioning base stations, and smart terminals carried by people or animals (such as smart phones); the external objects that the Ethernet connection link 1 interacts with include smart terminals (such as smart phones, computers, tablets) and the Internet of Vehicles platform. It should be further explained that the main function of the LIN connection link 5 (LIN bus network) is to provide auxiliary functions for the CAN connection link 4 (CAN bus network). It is suitable for body systems that do not require high bus performance, such as doors, seats, windows, lights, and other smart sensors and actuators. It is a low-cost, low-speed serial communication bus for distributed applications at the bottom of the car. It belongs to the local Internet and is an SAE-standard automotive Class A network.

[0028] This V2X terminal has gateway functions for multiple CAN connection links 4 and multiple LIN connection links 5, and is equipped with multiple Ethernet interfaces. The multiple Ethernet connection links 1 can implement on-board Ethernet switching, enabling the forwarding and routing of various signals. Therefore, the V2X terminal of this embodiment is a novel V2X terminal with both vehicle-wide gateway and multi-network switching functions. It should be noted that these various signals include various CAN messages and signals defined by various data within CAN messages, such as engine speed and battery indicator data. These signals also include various vehicle body-defined status signals, such as lights on or off, doors and windows closed or open, and so on. The forwarding and routing functions primarily enable the mutual forwarding of messages between different CAN channels, the forwarding of messages or signals via CAN channels to other LIN channels, and the forwarding of original CAN messages to an Ethernet network according to Ethernet transmission protocols. Ultimately, this allows data or messages from different physical network areas to be forwarded to other network domains or segments, thereby implementing network routing.

[0029] Preferably, the first microprocessor 2 is a 5G microprocessor, and the second microprocessor 3 is an MCU microprocessor. It should be noted that the 5G microprocessor, also known as the 5G module, mainly handles 5G communication-related transceiver tasks, such as the transmission and reception of communication data between the terminal and the external body system; the MCU microprocessor is a slightly lower-performance embedded processor that mainly handles the transmission and reception of communication data between the terminal and the body system.

[0030] As an optional embodiment, the Ethernet connection link 1 includes an Ethernet switching module 111 and at least two Ethernet processing layer modules 112; each Ethernet processing layer module 112 is connected to the Ethernet switching module 111, and the Ethernet switching module 111 is connected to the first microprocessor 2; each Ethernet processing layer module 112 is provided with a corresponding Ethernet interface.

[0031] In this example, the Ethernet switching module 111 can be an Ethernet switching chip. It should be noted that the Ethernet switching chip is a network switching chip based on semiconductor technology. Its principle is to route data packets from one port to another, and at the same time, it can filter and manage data packets. The switching chip generally adopts a store-and-forward method, that is, the entire data packet is first received in full, CRC check and error detection are performed, and then forwarded according to the target address. The Ethernet switching chip in this example supports high-speed transmission, multiple ports, high security, and adaptive support for data transmission at different rates. Further, in this example, the Ethernet processing layer module 112 can be an Ethernet PHY chip, which can be a chip that supports 10Base-T, 100Base-TX and 100Base-FX specifications.

[0032] As an optional embodiment, the V2X module 6 includes a V2X module 611 and a V2X radio frequency unit 612, which are interconnected. The V2X module 611 is connected to the first microprocessor 2, and the V2X radio frequency unit 612 is connected to a V2X antenna. Furthermore, the module 613 includes an encryption module 613, which is connected to the V2X radio frequency unit 612. The encryption module 613 ensures secure and reliable V2X data communication. It should be noted that the V2X module serves as the primary processing chip for vehicle-infrastructure collaboration and vehicle-to-vehicle communication, handling the relevant protocol stack and enabling vehicle-infrastructure data interaction.

[0033] As an optional embodiment, the CAN connection link 4 includes multiple CAN transceivers, each of which is connected to the vehicle body system via a CAN bus, forming no fewer than three CAN connection links 4. The number of CAN transceivers is no less than three. Preferably, the number of CAN connection links 4 is no fewer than six and no more than 16.

[0034] As an optional embodiment, the LIN connection link 5 includes multiple LIN transceivers, each of which is connected to the vehicle body system via a LIN bus, forming a LIN connection link 5 with no fewer than two channels, wherein the number of LIN transceivers is no less than two. Preferably, the LIN connection link 5 has a 6-channel or 32-channel link.

[0035] This example illustrates a V2X terminal with an in-vehicle gateway, further comprising a 5G module 7, a Wi-Fi module 8, a Bluetooth module 9, and a USB interface 10 connected to a first microprocessor 2. Each of the 5G module 7, Wi-Fi module 8, and Bluetooth module 9 is equipped with a corresponding antenna. Thus, the V2X terminal can implement data conversion and routing between multiple Ethernet, CAN, LIN, Bluetooth, and Wi-Fi networks, supporting the routing and isolation of network data between multiple Ethernet networks and between various networks, thus functioning as an in-vehicle gateway. Specifically, the 5G module 7 provides 5G / 4G communication capabilities; the Wi-Fi module 8 enables the vehicle's Wi-Fi to connect to external Wi-Fi hotspots and provide an internet hotspot for the entire vehicle, with the ability to switch between these modes; the Bluetooth module 9 enables vehicle data transmission and interaction, as well as the vehicle's Bluetooth digital key functionality. The Bluetooth module can replace a physical key, allowing users to unlock and drive their vehicle using their mobile phone without having to carry a physical key. The USB interface 10 provides network functionality via USB.

[0036] A V2X terminal with an on-board gateway in this example also includes a built-in storage module 11, a built-in battery 12 and a battery charging module 13; the built-in storage module 11 is connected to the first microprocessor 2, the built-in battery 12 is connected to the second microprocessor 3, and the battery charging module 13 is connected to the built-in battery 12.

[0037] In summary, the V2X terminal in this example possesses vehicle-wide gateway functionality, including multiple CAN networks, multiple LIN networks, and multiple Ethernet networks, as well as multi-channel Ethernet network routing and switching capabilities. It also features Wi-Fi, Bluetooth, and 4G / 5G communication. It can also provide internet access to external devices via USB port 10. Thus, a novel in-vehicle gateway function is implemented.
