[0025] In view of the fact that existing in-vehicle communication protocols are relatively simple and lack integration, this application proposes an in-vehicle gateway circuit and an in-vehicle communication system to overcome the above problems.
[0026] The following description, in conjunction with the accompanying drawings, introduces a vehicle gateway circuit and a vehicle communication system provided in this application.

[0039] In some embodiments, see Figure 4 As shown, the telematics control unit 70 is connected to the 100Mbps Ethernet interface 31 via the gateway interface module 40. Specifically, the telematics control unit 70 is connected to the 100Mbps Ethernet interface 31 via the circuit board connector 41. The telematics control unit 70, also known as a TBOX (Telematics Box), is used to communicate with the vehicle's backend system and mobile APP to realize vehicle information display and control via the mobile APP. The telematics control unit 70 needs to transmit a large amount of information, therefore Ethernet communication is used to meet user needs.
[0040] In some embodiments, see Figure 4 As shown, the radar 80 is connected to the 100Mbps Ethernet interface 31 via the gateway interface module 40. Specifically, the radar 80 is connected to the 100Mbps Ethernet interface 31 via the circuit board connector 41.
[0041] In some embodiments, see Figure 4 As shown, the debugging interface 90 is connected to the 100Mbps Ethernet interface 31 via the gateway interface module 40. Specifically, the debugging interface 90 is connected to the 100Mbps Ethernet interface 31 via the circuit board connector 41. The debugging interface 90 is an interface for an on-board automatic diagnostic system, used to connect testing tools to perform functional tests on the vehicle and obtain various information and statuses of the vehicle.
[0042] In some embodiments, see Figure 4 As shown, the Ethernet vehicle interface 100 is connected to the 100Mbps Ethernet interface 31 via the gateway interface module 40. Specifically, the Ethernet vehicle interface 100 is connected to the 100Mbps Ethernet interface 31 via the circuit board connector 41. The Ethernet vehicle interface 100 is a reserved expansion interface. When a new vehicle device is added, if the vehicle device supports Ethernet communication, the vehicle device connects to the Ethernet vehicle interface 100, and can then connect to the Ethernet switching chip 231 to achieve communication with other vehicle devices 2.
[0043] In some embodiments, see Figure 4 As shown, the vehicle-mounted bus interface 110 is connected to the CAN communication module 21 and / or the local interconnect network bus communication module 22 via the gateway interface module 40. Specifically, the vehicle-mounted bus interface 110 includes a CAN vehicle-mounted interface and a LIN vehicle-mounted interface; the CAN vehicle-mounted interface is connected to the CAN board-mounted interface via a circuit board connector 41; the LIN vehicle-mounted interface is connected to the LIN board-mounted interface via a circuit board connector 41. The vehicle-mounted bus interface 110 is a reserved expansion interface. When a new vehicle-mounted device is added, if the device supports CAN communication, it connects to the CAN vehicle-mounted interface, and can then connect to the CAN communication module 21 to achieve communication with other vehicle-mounted devices. When a new vehicle-mounted device is added, if it supports LIN communication, it connects to the LIN vehicle-mounted interface, and can then connect to the local interconnect network bus communication module 22 to achieve communication with other vehicle-mounted devices.
[0044] Based on the above embodiments, the vehicle gateway circuit provided in this application has the advantages of high integration and support for multiple communication protocols, enabling diverse vehicle communication between various vehicle devices and interfaces. Furthermore, the vehicle communication system reserves a bus vehicle interface and an Ethernet vehicle interface as expansion interfaces, allowing for the connection of new vehicle devices during use, thus providing scalability. Furthermore, this application allows for flexible adjustment of the number of Ethernet physical layer chips according to user needs; when the user reduces their communication requirements for Gigabit Ethernet, the number of Ethernet physical layer chips can be reduced, effectively lowering costs.
[0045] In some embodiments, when the power module 50 is supplying power normally and the control module 10, communication module 20, and gateway interface module 40 are working normally, the cockpit domain includes a screen. The screen receives a user-input request to increase the intensity of the ambient light. This request is transmitted sequentially to the cockpit domain controller 605 and the gateway interface module 40, and then transmitted to the Ethernet switching chip 231 via the first gigabit Ethernet interface 32 using the Ethernet communication protocol. The Ethernet switching chip 231 transmits the request to the control module 10 using the Ethernet communication protocol. The control module 10 generates a control command to increase the intensity of the ambient light according to the request and transmits it to the CAN communication module 21. Furthermore, the CAN communication module 21 uses the CAN protocol to send the control command to the gateway interface module 40 via the CAN onboard interface. The gateway interface module 40 transmits the control command to the ambient light controller 603. The ambient light controller 603 executes the control command to increase the intensity of the ambient light.
[0046] In some embodiments, when the power module 50 is supplying power normally and the control module 10, communication module 20, and gateway interface module 40 are working normally, the screen receives a user-inputted request to turn on the air conditioner. This request is transmitted sequentially to the cabin domain controller 605 and the gateway interface module 40, and then transmitted via the first gigabit Ethernet interface 32 using the Ethernet communication protocol to the Ethernet switching chip 231. The Ethernet switching chip 231 uses the Ethernet communication protocol to transmit the request to the control module 10. The control module 10 generates a control command to turn on the air conditioner based on the request. This control command is transmitted sequentially via the LIN protocol to the local interconnect bus communication module 22 and the gateway interface module 40. The gateway interface module 40 then transmits the control command to the air conditioner controller 604. The air conditioner controller 604 executes the control command and starts the air conditioner.
[0047] Based on the above embodiments, information interaction between different vehicle-mounted devices can be realized, and control of the vehicle-mounted devices can also be realized using the control module.
[0048] In summary, although the present application has disclosed the preferred embodiments as described above, the above preferred embodiments are not intended to limit the present application. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be determined by the scope defined in the claims.
