[0116] In some embodiments, the wireless communication connection between the gateway module 10 and the cloud server 60 is achieved through the wireless communication chip (e.g., 4G communication chip, 5G communication chip) in the gateway module 10.

[0117] In this embodiment, the driving domain module 20 interacts with the cloud server 60 through the gateway module 10 to achieve data sharing between the driving domain module 20 and the cloud server 60; the cockpit domain module 30 interacts with the cloud server 60 through the gateway module 10 to achieve data sharing between the cockpit domain module 30 and the cloud server 60.

[0118] Optionally, in some embodiments, the gateway module 10 is further configured to wirelessly connect with the external terminal 70; the driving domain module 20 is further configured to interact with the external terminal 70 via the gateway module 10; and the cockpit domain module 30 is further configured to interact with the external terminal 70 via the gateway module 10.

[0124] In some embodiments, the electrical signal described above is a digital signal.

[0125] Optionally, in some embodiments, at least one display module 50 for the driving domain and the display module 50 for the cockpit domain are the same display module 50; at least one camera module 40 for acquiring image data of the driving domain and the camera module 40 for acquiring image data of the cockpit domain are the same camera module 40.

[0126] For example, the camera module 40 in the driving domain includes a front main camera, a front long-range camera, a front wide-angle camera, a rear main camera, and a surround-view camera. The surround-view camera includes a left-side view camera and a right-side view camera. The camera module 40 in the cockpit domain includes a passenger camera, a driver camera, a passenger flow camera, and a surround-view camera. The surround-view camera in the driving domain and the surround-view camera in the cockpit domain are the same camera, meaning that the driving domain and the cockpit domain share a single surround-view camera.

[0127] The display module 50 in the driving domain includes a driving domain display screen; the display module 50 in the cockpit domain includes an instrument display screen, a rearview mirror display screen, a central control display screen, a rear headrest display screen, and an armrest display screen. The driving domain display screen and the central control display screen are the same display screen, which is shared by the driving domain and the cockpit domain.

[0128] In this embodiment, the driving domain and the cockpit domain can share the display module 50, and the driving domain and the cockpit domain can also share the camera module 40, so as to save hardware resources and reduce costs.

[0129] In some embodiments, the display module 50 in the driving domain and the display module 50 in the cockpit domain are different display modules 50, and the camera module 40 in the driving domain and the camera module 40 in the cockpit domain are different camera modules 40.

[0130] In this embodiment, the display module 50 in the driving domain and the display module 50 in the cockpit domain are independent of each other and do not affect each other, and the camera module 40 in the driving domain and the camera module 40 in the cockpit domain are independent of each other and do not affect each other.

[0131] In this embodiment, the gateway module 10 can transmit video between the vehicle and the cloud server 60 or the external terminal 70 (mobile phone or computer). For example, it can transmit video from the vehicle's main unit (driving domain module 20 or cockpit domain module 30) to the cloud platform via 4G or 5G networks, or transmit video from the vehicle's main unit to the cloud server 60 via Bluetooth or WIFI. Alternatively, it can transmit video from the cloud server 60 or the external terminal 70 to the vehicle's main unit via optical fiber. The gateway module 10 can also transmit prompts and warnings between the vehicle and the cloud server 60. For example, weather forecast information transmitted from the cloud server 60 that needs to be displayed on the central control screen. The gateway module 10 can also transmit the surround view image stitched from the cockpit domain module 30 that needs to be displayed on the central control screen, and the blind spot detection information from the driving domain module 20 that needs to be displayed on the instrument display screen.

[0132] This application also provides a vehicle, including the in-vehicle video system as described above.

[0133] The specific implementation method of the in-vehicle video system is similar to that of the aforementioned in-vehicle video system, and will not be repeated here.

[0134] In related technologies, both the video system in the driver domain and the video system in the cockpit domain use SerDes digital transmission to transmit image and video data. The SerDes digital transmission signal can transmit up to 15 meters, which is a limited distance. For large heavy trucks or large trailers, due to the length of the vehicle body, the video from the rear camera cannot be transmitted to the front of the vehicle using SerDes digital transmission.

[0135] In this embodiment, since the gateway module 10 is connected to the driving domain module 20, the cockpit domain module 30, each camera module 40 and each display module 50 via optical fiber, the optical fiber transmission has a longer distance than the SerDes digital transmission method in related technologies, which can meet the needs of image and video data transmission for vehicles with long bodies.

[0136] In related technologies, intelligent driving systems and intelligent cockpit systems are independent of each other. The intelligent driving system and intelligent cockpit system communicate with each other through an on-board gateway, such as CAN or Ethernet. The communication bandwidth is limited and the transmission delay is large, which cannot realize the sharing of multiple videos. In addition, the cameras of the intelligent driving system and intelligent cockpit system are independent of each other, requiring a large number of cameras.

[0137] In this embodiment, the driving domain module 20 and the cockpit domain module 30 communicate via optical fiber. Since optical fiber has high bandwidth and low transmission delay, it can realize multi-video sharing between the driving domain and the cockpit domain. Furthermore, the driving domain and the cockpit domain share the camera module 40, which reduces the number of cameras required, saves costs and space.

[0138] The embodiments of this application can solve problems such as high video transmission cost, limited transmission distance, and low resolution of transmitted video. At the same time, it can realize video sharing between intelligent driving system and intelligent cockpit system, reducing the number of cameras required.

[0139] In this embodiment, since the driving domain module 20 and the cockpit domain module 30 are connected via optical fiber, the video signals between the intelligent driving system and the intelligent cockpit system can be transmitted directly without going through the gateway module 10, making it more convenient and faster for the intelligent driving system and the intelligent cockpit system to share video with less transmission delay; the gateway module 10 can realize the transmission of video, prompts and warning information between the vehicle host and the camera module 40, the display 51, the cloud server 60 and the external terminal 70.

[0140] In summary, in this embodiment, each camera module 40 acquires image data and forwards it through the gateway module 10 to at least one of the driving domain module 20 and the cockpit domain module 30. The driving domain module 20 then generates first video data based on the image data from the driving domain and forwards it through the gateway module 10 to the display module 50 in the driving domain. Similarly, the cockpit domain module 30 generates second video data based on the image data from the cockpit domain and forwards it through the gateway module 10 to the display module 50 in the cockpit domain. Finally, each display module 50 displays at least one of the first and second video data. Since the gateway module 10 is connected to the driving domain module 20, the cockpit domain module 30, each camera module 40, and each display module 50 via optical fiber, the optical fiber transmission has a higher bandwidth compared to the transmission methods in related technologies, resulting in higher video resolution displayed by the display module 50 and thus improving the user experience.
