Description

Technical Field

[0001] This application relates to the field of vehicle intelligent control technology, and particularly to an in-vehicle video system and a vehicle. Background Art

[0002] With the development of intelligent driving technology, there are mainly two ways of in-vehicle video transmission: Serializer / Deserializer (Serdes) transmission and digital transmission and Analog High Definition (AHD) transmission. In Serdes transmission, the cost of coaxial cable bundles is relatively high, and the signal transmission distance is limited. Thus, for large heavy trucks or large trailers, not only is the video transmission cost relatively high through Serdes transmission, but also due to the long vehicle body, it is difficult to transmit the video of the camera at the rear of the vehicle to the front of the vehicle through Serdes transmission. Additionally, as the resolution of in-vehicle videos continues to increase, the transmission bandwidth of Serdes has gradually reached its bottleneck. For AHD transmission, the transmission bandwidth is even lower, and it supports transmitting videos up to 1080P at most. Moreover, as time goes by, the video resolution of the camera will become higher and higher, resulting in high-resolution videos being very difficult to transmit through AHD transmission.

[0040] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0041] Generally, an in-vehicle video system may include an intelligent driving unit and an intelligent cockpit unit. The intelligent driving unit is used to implement the autonomous driving or assisted driving capabilities of the vehicle. The intelligent cockpit unit is used to perform human-machine interaction with the passengers and drivers, so as to improve the experience and comfort of the passengers and drivers when taking the vehicle. Both the intelligent driving unit and the intelligent cockpit unit generally include a video acquisition component and a display device. For example, the video acquisition component of the intelligent driving unit is the first video acquisition component. The first video acquisition component may include, but is not limited to, a front main camera, a front long-distance camera, a front fisheye camera, a rear main camera, etc., and is mainly used for monitoring the surrounding environment of the vehicle body during driving for driving safety monitoring. The display device of the intelligent driving unit may include an intelligent driving display screen. The video acquisition component of the intelligent cockpit unit is the second video acquisition component. The second video acquisition component may include, but is not limited to, a surround view camera, a monitoring camera, a driver monitoring system (Drive Monitor System, DMS) camera, a passenger flow camera, an electronic rearview mirror camera, etc. The display device of the intelligent cockpit unit may include an intelligent cockpit display screen. The intelligent cockpit display screen may include, but is not limited to, a central control screen, a rear headrest screen, an armrest screen, an instrument display screen, and an electronic rearview mirror display screen. The intelligent driving unit and the intelligent cockpit unit communicate through an intelligent vehicle gateway, such as a Controller Area Network (CAN) and Ethernet. However, the communication bandwidth in the related technology is limited, the transmission delay is large, and multi-video sharing cannot be achieved. Moreover, if all the functions of the intelligent driving unit and the intelligent cockpit unit need to be realized, a full set of cameras need to be arranged, which is likely to cause waste of cameras and result in a high cost of the in-vehicle video system.

[0042] Therefore, the embodiments of the present application propose an in-vehicle video system and architecture technology based on optical fiber transmission. The transmission architecture adopts optical fiber transmission for the full-link video signal of "video acquisition device (such as various types of cameras) - host (such as intelligent driving unit and intelligent cockpit unit, etc.) - display screen (such as intelligent driving display screen and intelligent cockpit display screen, etc.)". In the embodiments of the present application, signals are transmitted between the video acquisition device and the host, and between the host and the display screen through an optical fiber communication component. The optical fiber communication component includes an optoelectronic conversion module, which can realize the mutual conversion between optical fiber signals and electrical signals.

[0043] The sensing signal of the image sensor in the video acquisition device is an electrical signal, which is converted into an optical fiber signal by the optoelectronic conversion module and output. The video input and output of the intelligent driving unit and the intelligent cockpit unit are both optical fiber signals, and the internal optoelectronic conversion module converts the optical fiber signal and the electrical signal. The video input of the display screen is an electrical signal. Moreover, the intelligent driving unit and the intelligent cockpit unit in the in-vehicle video system of the embodiments of the present application are connected through an optical fiber communication component, and the bandwidth can reach 50 Gbps, realizing video sharing between the intelligent driving unit and the intelligent cockpit unit. In this way, not only can problems such as high video transmission cost, limited transmission distance, and inability to transmit high-resolution video be solved, but also video sharing between the intelligent driving unit and the intelligent cockpit unit can be achieved. The intelligent driving unit can share the side cameras of the surround view, the surround view can share the front main camera and the rear main camera of the intelligent driving, and the electronic rearview mirror can share the side cameras of the surround view, which can save the number of cameras and thus reduce the waste of cameras.

[0044] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an in-vehicle video system provided in the embodiments of the present application. The in-vehicle video system includes an intelligent driving unit 100 and an intelligent cockpit unit 200. The intelligent driving unit 100 may include a driving processor 110 and a first video acquisition component 120. The intelligent cockpit unit 200 may include a cockpit processor 210.

[0045] In the embodiment of the present application, the intelligent driving processor 110 undertakes the computing, planning, and control services of vehicle intelligent driving. The intelligent cabin processor 210 is responsible for controlling the intelligent cabin unit 200 to improve the riding comfort of the passengers and provide entertainment and information services, thereby ensuring the safety of the passengers and enhancing the riding experience of the passengers. The first video acquisition component 120 may include, but is not limited to, a front main camera, a front long-distance camera, and a front wide-angle camera for collecting images in front of the vehicle, a rear main camera for collecting images behind the vehicle, and a surround-view camera, etc. In one example, the surround-view camera may include a left-side view camera and a right-side view camera for collecting images on the left and right sides of the vehicle. After the first video acquisition component 120 acquires the first video data covering the front, rear, left, and right sides of the vehicle, the first video data may be transmitted to the intelligent driving processor 110 through the first optical fiber communication component 410.

[0046] In the embodiment of the present application, the first video acquisition component 120 is communicatively connected to the intelligent driving processor 110 through the first optical fiber communication component 410. The intelligent driving processor 110 is communicatively connected to the intelligent cabin processor 210 through the second optical fiber communication component 420 to transmit the first video data acquired by the first video acquisition component 120 to the intelligent cabin processor 210 through the optical fiber. In this way, it is possible to realize the sharing of the first video data acquired by the first video acquisition component 120 between the intelligent driving unit 100 and the intelligent cabin unit 200. In the embodiment of the present application, since the optical fiber transmission uses optical signals, the optical signals have less loss during transmission in the optical fiber, faster transmission speed, and at the same time, have a higher bandwidth. Therefore, a longer transmission distance can be achieved and the transmission of higher-resolution videos can be supported.

[0047] Please refer to Figure 2 and Figure 3 , Figure 2 is a schematic structural diagram of an optical fiber communication component provided in an embodiment of the present application. Figure 3 is a schematic structural diagram of an optical fiber communication component provided in another embodiment of the present application.

[0048] In the embodiment of the present application, the first optical fiber communication component 410 may include a first optoelectronic conversion module 411 and a second optoelectronic conversion module 412 that are disposed in the intelligent driving unit 100 and communicatively connected to each other. The first optoelectronic conversion module 411 is electrically connected to the first video acquisition component 120, and the second optoelectronic conversion module 412 is electrically connected to the intelligent driving processor 110. After the first video acquisition component 120 acquires the first video data through the image sensor disposed therein, the first video data is transmitted to the first optoelectronic conversion module 411. The first optoelectronic conversion module 411 converts the electrical signal of the image sensor into an optical fiber signal, and then converts the optical fiber signal into an electrical signal through the second optoelectronic conversion module 412 and transmits it to the intelligent driving processor 110.

[0049] As Figure 2 shown, in an embodiment of the present application, the second optical fiber communication component 420 may include a third optoelectronic conversion module 421 disposed in the intelligent driving unit 100 and a fourth optoelectronic conversion module 422 disposed in the intelligent cockpit unit 200. The third optoelectronic conversion module 421 and the fourth optoelectronic conversion module 422 are communicatively connected. The third optoelectronic conversion module 421 is electrically connected to the intelligent driving processor 110, and the fourth optoelectronic conversion module 422 is electrically connected to the intelligent cockpit processor 210.

[0050] In this embodiment, the intelligent driving unit 100 and the intelligent cockpit unit 200 communicate directly through the second optical fiber communication component 420. The third optoelectronic conversion module 421 in the intelligent driving unit 100 converts the electrical signal in the intelligent driving processor 110 into an optical fiber signal and transmits it to the fourth optoelectronic conversion module 422. Then, the fourth optoelectronic conversion module 422 converts the optical fiber signal into an electrical signal and transmits it to the intelligent cockpit processor 210. In this way, the first video data in the intelligent driving unit 100 can be directly transmitted to the intelligent cockpit unit 200 through optical fiber transmission, and the second video data in the intelligent cockpit unit 200 can be transmitted to the intelligent driving unit 100, without passing through the vehicle-mounted intelligent gateway 300. In this way, it is more convenient and faster to share videos between the intelligent driving unit 100 and the intelligent cockpit unit 200, and the transmission delay is smaller.

[0051] As Figure 3 shown, in another embodiment of the present application, the vehicle-mounted video system may further include a vehicle-mounted intelligent gateway 300 connected between the intelligent driving unit 100 and the intelligent cockpit unit 200. The second optical fiber communication component 420 may include a third optoelectronic conversion module 421 disposed in the intelligent driving unit 100, a fourth optoelectronic conversion module 422 disposed in the intelligent cockpit unit 200, and a fifth optoelectronic conversion module 423 disposed in the vehicle-mounted intelligent gateway 300. The fifth optoelectronic conversion module 423 is communicatively connected between the third optoelectronic conversion module 421 and the fourth optoelectronic conversion module 422. The third optoelectronic conversion module 421 is electrically connected to the intelligent driving processor 110, and the fourth optoelectronic conversion module 422 is electrically connected to the intelligent cockpit processor 210.

[0052] In this embodiment, the intelligent driving unit 100 and the intelligent cockpit unit 200 do not directly perform optical fiber communication. Instead, the vehicle-mounted intelligent gateway 300 is used as a transfer medium to achieve video sharing between the intelligent driving unit 100 and the intelligent cockpit unit 200. The third optoelectronic conversion module 421 disposed in the intelligent driving unit 100 is connected to the fifth optoelectronic conversion module 423 disposed in the vehicle-mounted intelligent gateway 300 to convert the electrical signal of the first video data into an optical fiber signal and transmit it to the vehicle-mounted intelligent gateway 300. At the same time, the fifth optoelectronic conversion module 423 is connected to the fourth optoelectronic conversion module 422 disposed in the intelligent cockpit unit 200 to convert the optical fiber signal of the first video data into an electrical signal and transmit it to the intelligent cockpit processor 210. Thus, video sharing between the intelligent driving unit 100 and the intelligent cockpit unit 200 is achieved through the vehicle-mounted intelligent gateway 300. After the first video data is transmitted to the vehicle-mounted intelligent gateway 300 through optical fiber transmission in this embodiment, if the vehicle-mounted intelligent gateway 300 needs to transmit the first video data to the cloud server, it does not need to pass through the wired Ethernet and can directly perform optical fiber transmission, with a relatively small transmission delay, which can improve the transmission between the vehicle-mounted video system and the cloud server.

[0053] Please refer to Figure 4 and Figure 5 , Figure 4 which is a schematic structural diagram of a vehicle-mounted video system provided in a specific embodiment of the present application, Figure 5 which is a schematic structural diagram of a vehicle-mounted video system provided in another specific embodiment of the present application.

[0054] In the embodiment of the present application, the vehicle-mounted video system may include an intelligent driving unit 100, an intelligent cockpit unit 200, and a vehicle-mounted intelligent gateway 300 connected between the intelligent driving unit 100 and the intelligent cockpit unit 200.

The intelligent cockpit unit 200 may include an intelligent cockpit processor 210, a second video acquisition component 220, and an intelligent cockpit display screen 230. In the embodiment of the present application, the data acquired by the first video acquisition component 120 is the first video data, and the data acquired by the second video acquisition component 220 is the second video data. Since the intelligent driving unit 100 and the intelligent cockpit unit 200 can achieve data sharing, both the intelligent driving processor 110 and the intelligent cockpit processor 210 may include the first video data and the second video data. The vehicle-mounted intelligent gateway 300 may include a gateway processor 310. The vehicle-mounted intelligent gateway 300 may also communicate with the cloud server 700 and the terminal device 800 to transmit the video data in the vehicle-mounted intelligent gateway 300 to the cloud server 700 and the terminal device 800, or transmit the video data of the cloud server 700 or the terminal device 800 to the intelligent driving unit 100 or the intelligent cockpit unit 200 through the wired Ethernet.

After processing the first video data, the intelligent driving processor 110 can transmit the processed first video data to the intelligent driving display screen 130 through the third optical fiber communication component 430.

[0056] In an embodiment of the present application, the third optical fiber communication component 430 may include a sixth optoelectronic conversion module 431 and a seventh optoelectronic conversion module 432 that are communicatively connected to each other. The sixth optoelectronic conversion module 431 is electrically connected to the intelligent driving processor 110, and the seventh optoelectronic conversion module 432 is electrically connected to the intelligent driving display screen 130. The intelligent driving processor 110 can convert the electrical signal of the processed first video data into an optical fiber signal through the sixth optoelectronic conversion module 431 and then transmit it to the seventh optoelectronic conversion module 432. Moreover, the intelligent driving processor 110 can also receive the electrical signal of the second video data processed by the intelligent cabin processor 210, then convert it into an optical fiber signal through the sixth optoelectronic conversion module 431, and then transmit it to the seventh optoelectronic conversion module 432. Then the seventh optoelectronic conversion module 432 converts the optical fiber signal into an electrical signal and transmits it to the intelligent driving display screen 130. In this way, the first video data or the second video data can be transmitted to the intelligent driving display screen 130 for display through the third optical fiber communication component 430 by optical fiber.

[0057] In an embodiment of the present application, the second video acquisition component 220 may include, but is not limited to, a monitoring camera for collecting passenger images, a DMS camera for collecting driver images, and a passenger flow camera for counting the number of passengers. The intelligent cabin display screen 230 may include, but is not limited to, an instrument display screen, an electronic rearview mirror display screen, a central control screen, a headrest screen, and an armrest screen, etc. The intelligent cabin display screen 230 can provide services and data such as vehicle operation status, monitoring, conferencing, and entertainment to the driver and passengers, and can also identify or receive instruction information from the driver and passengers, such as touch instructions, voice instructions, or gesture instructions, etc., so as to realize the human-machine interaction between the vehicle and the driver and passengers.

In this way, the second video data collected by the second video acquisition component 220 can be transmitted to the intelligent cockpit processor 210 through the fourth optical fiber communication component 440, and the intelligent cockpit processor 210 can transmit the electrical signal of the received first video data or the processed second video data to the intelligent cockpit display screen 230 through the fifth optical fiber communication component 450.

[0059] In an embodiment of the present application, the fourth optical fiber communication component 440 may include an eighth optoelectronic conversion module 441 and a ninth optoelectronic conversion module 442 that are communicatively connected to each other. The eighth optoelectronic conversion module 441 is electrically connected to the intelligent cockpit processor 210, and the ninth optoelectronic conversion module 442 is electrically connected to the second video acquisition component 220. After the second video acquisition component 220 collects the second video data through the image sensor disposed therein, it transmits the second video data to the ninth optoelectronic conversion module 442. The ninth optoelectronic conversion module 442 converts the electrical signal of the image sensor into an optical fiber signal, and then converts the optical fiber signal into an electrical signal through the eighth optoelectronic conversion module 441 and transmits it to the intelligent cockpit processor 210.

[0060] In an embodiment of the present application, the fifth optical fiber communication component 450 may include a tenth optoelectronic conversion module 451 and an eleventh optoelectronic conversion module 452 that are communicatively connected to each other. The tenth optoelectronic conversion module 451 is electrically connected to the intelligent cockpit processor 210, and the eleventh optoelectronic conversion module 452 is electrically connected to the intelligent cockpit display screen 230. The intelligent cockpit processor 210 can convert the electrical signal of the first video data or the second video data into an optical fiber signal through the tenth optoelectronic conversion module 451 and then transmit it to the eleventh optoelectronic conversion module 452. Then, the optical fiber signal is converted into an electrical signal through the eleventh optoelectronic conversion module 452 and transmitted to the intelligent cockpit display screen 230. In this way, the second video data can be transmitted to the intelligent cockpit display screen 230 through the fifth optical fiber communication component 450 for display.

[0061] In an embodiment of the present application, the intelligent driving processor 110 can be communicatively connected to the intelligent cockpit processor 210 through the second optical fiber communication component 420, so as to transmit the first video data collected by the first video acquisition component 120 to the intelligent cockpit processor 210 through the optical fiber, and transmit the second video data collected by the second video acquisition component 220 to the intelligent driving processor 110 through the optical fiber.

[0062] Since the safety level of the intelligent driving unit is higher than that of the intelligent cockpit unit, in the embodiments of the present application, the surround-view cameras in the traditional intelligent cockpit unit 200 are arranged in the intelligent driving unit 100. Through the second optical fiber communication component, the intelligent cockpit unit 200 can share the first video data collected by the surround-view cameras and the like in the intelligent driving unit 100. At the same time, the intelligent driving unit 100 can also share the second video data collected by the intelligent cockpit unit 200.

[0064] In this embodiment, the intelligent driving unit 100 and the intelligent cockpit unit 200 communicate directly through the second optical fiber communication component 420. The third optoelectronic conversion module 421 in the intelligent driving unit 100 converts the electrical signal in the intelligent driving processor 110 into an optical fiber signal and transmits it to the fourth optoelectronic conversion module 422. Then, the fourth optoelectronic conversion module 422 converts the optical fiber signal into an electrical signal and transmits it to the intelligent cockpit processor 210. In this way, the first video data in the intelligent driving unit 100 can be directly transmitted to the intelligent cockpit unit 200 through optical fiber transmission, and the second video data in the intelligent cockpit unit 200 can be transmitted to the intelligent driving unit 100 without passing through the vehicle-mounted intelligent gateway 300. In this way, it can be more convenient and faster for the intelligent driving unit 100 and the intelligent cockpit unit 200 to share videos, and the transmission delay is smaller.

Taking the transmission of the first video data of the intelligent driving unit 100 to the intelligent cockpit unit 200 as an example, the third optoelectronic conversion module 421 disposed in the intelligent driving unit 100 is connected to the fifth optoelectronic conversion module 423 disposed in the vehicle-mounted intelligent gateway 300, and the electrical signal of the first video data is converted into an optical fiber signal and transmitted to the vehicle-mounted intelligent gateway 300.

After the first video data or the second video data is transmitted to the vehicle-mounted intelligent gateway 300 through optical fiber transmission in this embodiment, if the vehicle-mounted intelligent gateway 300 needs to transmit the first video data or the second video data to the cloud server 700, it does not need to pass through the wired Ethernet and can directly perform optical fiber transmission, with a smaller transmission delay, which can improve the transmission between the vehicle-mounted video system and the cloud server 700 and the terminal device 800.
