Information interaction system and vehicle based on vehicle Ethernet

Abstract

The invention discloses an information exchange system based on vehicle Ethernet and a vehicle. The system includes a vehicle Ethernet gateway, which is respectively connected with a central control multimedia device and a panoramic image device, and is used for connecting between the center control multimedia device and the panoramic image device. Perform data transmission; the panoramic image device is provided with a first Ethernet interface for sending panoramic video data to the vehicle Ethernet gateway through the first Ethernet interface; the central control multimedia device is provided with a second Ethernet interface for passing The second Ethernet interface obtains panoramic video data from the vehicle-mounted Ethernet gateway, and displays the panoramic video data. The system and vehicle of this embodiment enable data interaction between the central control multimedia device and the panoramic imaging device in various forms, which enriches the interaction mode between the central control multimedia device and the panoramic imaging device, and reduces the cost of the central control multimedia device. The cost of communication with the panoramic imaging device.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an information interaction system based on a vehicle Ethernet and a vehicle. Background technique [0002] With the increasing number of vehicles, in order to facilitate driving and safely view the surrounding environment and ensure driving safety, panoramic imaging devices are generally installed on vehicles. The panoramic video is displayed on the screen of the station. [0003] In the related art, the panoramic image device and the vehicle multimedia system are connected to transmit the stitched panoramic video through a low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS) connection. Specifically, the panoramic main controller in the panoramic image device directly transmits the video to the LVDS conversion IC integrated circuit (Integrated Circuit). Convert and display the panoramic video on the screen of the vehicle center console. [0004] H...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of realizing the present invention, the inventors found that there are at least the following technical problems in related technologies: in the entire transmission process, LVDS can only transmit video information with a fixed format at the physical layer, and the flexibility is very low, and it will not perform video processing. processing, and cannot transfer pictures and file information

In addition, the signal transmission distance of LVDS is also limited, which has great limitations, and the hardware cost of converting IC and wire is relatively high
