[0007] In a possible implementation, controlling the display device to adjust the display of the first image from the host to simultaneously display the first image and the second image in a preset display mode includes: controlling the display device to adjust the display of the first image to display the second image in a partial area of ​​the first image, or controlling the display device to adjust the display of the first image to display the first image in a partial area of ​​the second image, or controlling the display device to adjust the display of the first image to display the first image and the second image in different display areas, respectively.

[0010] In a possible implementation, the system-level chip is also used to determine a target signal based on the first image and the second image when the assisted driving start instruction is detected, and send the target signal to the display device, wherein the target signal is used to instruct the display device to display the first image on the background layer and the second image on the top layer, or to instruct the display device to display the second image on the background layer and the first image on the top layer.

[0022] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0023] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0024] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0025] In order to facilitate those skilled in the art to understand the technical solution provided by the embodiments of the present disclosure, the technical environment in which the technical solution is implemented is described below.

[0026] At present, the display solutions of video products in the automotive industry are mainly concentrated on chip solutions such as TI / MAXIM, which realize transmission / display through the video serial transmission / recovery pairing method. Taking the video signal as an example, Figure 1a As shown, the processor generates the original display signal (Digital Security Interface, DSI), that is, the video signal to be transmitted. The video signal is modulated by the serializer chip and transmitted to the display terminal. The display processor first restores the transmitted high-frequency signal to the original video signal through the deserializer chip, and then sends the signal to the display screen for display. In this way, the entire link process of generating, transmitting and displaying the original display signal is completed.

[0027] Existing passenger cars often add some visual accessories and auxiliary driving products after leaving the factory due to differences in configuration and different configurations of different models, such as Advanced Driving Assistance System (ADAS), 360-degree surround view system, electronic rearview mirror (camera-monitor system, CMS), reversing image and other products. In other words, on the basis of some original functional interfaces of the vehicle system, the relevant interfaces of third-party products such as ADAS are further displayed, and the display of these related interfaces corresponds to auxiliary function display signals. In order to give the driver a better human-computer interaction experience, it is usually necessary to connect the auxiliary function display signal to the central control screen or instrument system of the vehicle computer, so that the driver can better use third-party products to perceive special road conditions that may appear at any time and identify potential driving safety hazards. In this way, it is particularly important to study how to connect the original display signals of the vehicle and the signals related to the installed third-party products to the vehicle display terminal.

[0028] There are three main types of display signal access methods. One is the original car reserved video input interface, such as the reversing image input channel. The other is the signal truncation method, which uses electronic switches or relays to force the display signal to switch between different devices, for example, Figure 1b As shown in the figure, the original vehicle host and the additional equipment send their respective display signals to the relay / electronic switch, and then the signal is switched through the relay / electronic switch, and finally displayed on the vehicle display terminal. The third is to use FPGA chips / special ICs to superimpose display signals of different devices, for example, Figure 1c As shown, the original vehicle host and the additional equipment send their respective display signals to the FPGA dedicated IC for signal superposition, and finally display them on the vehicle display terminal.

[0029] At present, most technical solutions are based on switch selection switching and FPGA switching. The disadvantages of these two solutions are that the use of electronic switches or relays to switch often causes signal display failures such as flashing screen, black screen, flower screen, sawtooth, scrolling screen, and touch screen data loss. On the one hand, the high chip cost of using FPGA solutions / special ICs greatly increases the equipment cost and solution design complexity, and the hardware cost and development cost are relatively high. The general bandwidth of domestic low-cost FPGAs is around 800Mbps, which is difficult to handle large-resolution display screens. Therefore, these solutions have gradually failed to meet market demand and industry technology development needs.

[0030] In order to solve the above technical problems, the embodiments of the present disclosure propose an in-vehicle display system for a vehicle. The low-cost picture-in-picture implementation solution used by the system can respond to the assisted driving start command and display the original in-vehicle function screen and the assisted driving screen at the same time. On the one hand, it can solve the problems of black screen, jitter, screen flashing, jagged edges, snowflakes, etc. caused by signal interruption caused by forced signal switching in related technologies. On the other hand, it does not need to be implemented by using FPGA, which greatly reduces the complexity of hardware design and material costs.

[0031] Now combined Figures 2 to 4 The vehicle-mounted display system provided by the embodiment of the present disclosure is schematically described. Figure 2 As shown, the vehicle-mounted display system may include a host, an auxiliary driving device, and a display device.

[0032] The host can be used to send a default display image to the system-on chip (SOC) when the vehicle is detected to be started, so that the display device displays the default display image. The default display image can be the main screen that is pre-set by the vehicle and displayed in the display area of ​​the display device. For example, the main screen can display conventional functional controls such as Bluetooth connection controls, audio playback controls, and vehicle setting controls. The host can also be used to send the corresponding functional image / screen to the system-on chip when a function startup instruction is detected, so that the display device displays the functional image. The functional image generally depends on the corresponding function startup instruction. Function startup instructions include but are not limited to Bluetooth connection instructions, audio playback instructions, map navigation instructions, and vehicle setting instructions. Taking the Bluetooth connection function as an example, the host sends the corresponding Bluetooth connection image to the system-on chip when the Bluetooth connection instruction is detected, so that the user can connect to Bluetooth through the Bluetooth connection screen displayed on the display device. Whether it is a default display image or a functional image, these images generated by the host are collectively referred to as first images in this embodiment.

[0033] The assisted driving device can be used to provide assisted driving functions for third parties, such as a 360-degree surround view function. The assisted driving device may include a system-level chip and an assisted driving camera. The assisted driving camera can be used to capture images of the surrounding environment of the vehicle to obtain camera images, and send the captured camera images to the system-level chip, so that the system-level chip determines the assisted driving image, i.e., the second image, based on the camera image. The second image can be used to indicate the distribution of pedestrians, vehicles, buildings, etc. around the vehicle. It should be noted that assisted driving cameras refer to a type of camera used to achieve assisted driving, and the number of cameras can be flexibly set according to actual needs. For example, for a 360-degree surround view system, 4 cameras can be set on the vehicle to obtain 4 captured images.

[0034] The system-level chip can be used to control the display device to adjust the first image displayed from the host to display the first image and the second image simultaneously in a preset display mode when an assisted driving start command is detected, wherein the display mode is superimposed display or partitioned display. In this way, the vehicle-mounted display system can intelligently adjust the display mode of the display device to achieve the synchronous display of the first image and the second image when an assisted driving start command is detected. This intelligent design not only improves the driver's visual experience, but also makes the driving assistance system more intuitive and easy to use. The driver can easily obtain the required information without frequently switching his or her sight or relying on other devices.

[0035] Among them, controlling the display device to adjust the display of the first image from the host to simultaneously display the first image and the second image in a preset display mode may include: controlling the display device to adjust the display of the first image to superimpose the second image on the first image for simultaneous display, or controlling the display device to adjust the display of the first image to superimpose the first image on the second image for simultaneous display. Among them, in this way, the vehicle-mounted display system provides two flexible superimposed display modes, namely, the second image is superimposed on the first image or the first image is superimposed on the second image. This design allows the driver to choose the display mode that best suits the current situation according to his or her preferences and driving needs, which is more flexible. For example, when you need to focus on navigation information, you can choose to superimpose the second image that focuses on displaying the surrounding environment on the first image at a smaller scale, just like Figure 3 As shown; when it is necessary to observe the surrounding environment carefully, the first image currently displayed, which focuses on displaying navigation information, can be superimposed on the second image at a smaller scale. In addition, when the display device displays the first image and the second image in a superimposed display manner, the system-level chip can also control the display device to display the superimposed image at the target position when a movement operation of the superimposed image (taking the superimposition of the second image on the first image as an example, in this case the superimposed image is the second image) is detected. For example, the superimposed image after movement can be located in the middle of the display area, as shown in FIG. Figure 4 In addition to the moving operation, the system-level chip can also detect the scaling operation of the overlay image to control the size of the displayed overlay image.

[0036] Among them, controlling the display device to adjust the display of the first image from the host to display the first image and the second image simultaneously according to the preset display mode may include: controlling the display device to adjust the display of the first image to display the second image in a partial area of ​​the first image, or controlling the display device to adjust the display of the first image to display the first image in a partial area of ​​the second image, or controlling the display device to adjust the display of the first image to display the complete first image and the complete second image in different display areas. In this way, the vehicle-mounted display system can provide rich driving information without interfering with the driver's line of sight through embedded display or direct partition display, so that the driver can quickly capture key information, such as navigation instructions, vehicle status, surrounding environment, etc., thereby improving the speed and accuracy of driving decisions. In addition, the system-level chip can also control the display device to display the second image in the left area and the first image in the right area when the display device displays the complete first image and the complete second image in different display areas, such as displaying the first image in the left area of ​​the display area and displaying the second image in the right area, when a region switching operation is detected.

[0037] The system-level chip can also be used to control the display device to switch the display mode when a display switching instruction is detected, for example, switching the overlay display to the partition display.

[0038] like Figure 2 As shown, the host may include a first serializer chip (or a first serial communication chip), and the auxiliary driving device may also include a first deserializer chip (or a first deserialization communication chip). The host can also be used to determine a first signal based on the first image, and send the first signal to the auxiliary driving device through the first serializer chip. The first serializer chip can be used to convert the first signal into a plurality of first serial signals, and transmit the plurality of first serial signals serially to the first deserializer chip. The first deserializer chip can be used to restore the received plurality of first serial signals to the first signal, and send the first signal to the system-level chip. The specific models of the first serializer chip and the first deserializer chip, as well as the second serializer chip and the second deserializer chip in the following text, can be flexibly selected according to actual needs. In this way, the vehicle-mounted display system transmits the first image from the host to the system-level chip through the cooperation of the first serializer chip and the first deserializer chip, which can reduce the number and cost of wiring harnesses in the vehicle-mounted environment, and solve the problem of transmission error.

[0039] Different brands and models in the automotive industry will have different high and low configurations, because some low-end models will still be equipped with third-party assisted driving products such as panoramic view, streaming media, mobile phone interconnection projection, millimeter wave radar, automatic parking, etc. after leaving the factory. In order to intuitively display the vehicle status, these products will be linked with the central control screen, that is, the display device. Some of these products are original accessories, and some are extended and installed products. For example, this vehicle display system can realize the fusion of multiple image layers through the system-level chip, placing the content displayed on the original car screen, that is, the first image, into a separate layer and using this layer as the background layer, placing the content related to the additional equipment and the second image into another separate layer and superimposing this layer on the top layer above the background layer for display, and then combining some third-party auxiliary switching and touch logic to achieve lossless additional installation of the car central control. The system-level chip can also be used to determine the target signal based on the first image and the second image when the assisted driving start instruction is detected, and send the target signal to the display device. The target signal is used to instruct the display device to display the first image in the background layer and the second image in the top layer, or to instruct the display device to display the second image in the background layer and the first image in the top layer. The target signal may be a signal of a type such as a video signal or an image signal, and the present disclosure does not limit this. Taking the target signal as a video signal as an example, the in-vehicle display system based on a new SOC and a multi-camera input solution provided in the embodiment of the present disclosure uses a first deserializer chip to first restore the received serial video signal, i.e., the multiple first serial signals mentioned above, to a common first signal, wherein the first signal adopts a common signal format (e.g., LVDS / RGB / MIPI / BT656 / BT1120, etc.), and then disguises the deserialized video signal, i.e., the first signal, as a camera input signal, such as transmitting the deserialized first signal to the SOC in the form of a commonly used signal interface such as mipi. The application in the SOC can be used to determine the target signal based on the real camera input signal for indicating the second image sent from the auxiliary driving camera, and the first signal disguised as a camera input signal but actually used to indicate the first image, so as to display the first image and the second image simultaneously at the display device, i.e., to show the superposition or partitioning effect. In this way, the overlay or partitioning of picture-in-picture is completed while ensuring the uninterrupted communication link, solving the problems of screen flashing, jagged edges, black screen, scrolling, etc. caused by signal interruption, while eliminating the FPGA / dedicated IC, greatly reducing the cost, and the problem of bandwidth limitation that cannot achieve high-resolution image overlay.

[0040] For example, if Figure 2As shown, the system-level chip may include two software modules, namely, an image processing module and an image fusion module. The assisted driving camera may send the acquired multiple camera images to the image processing module, which may be used to perform image processing on the multiple camera images acquired by the assisted driving camera to generate an assisted driving image, namely, a second image, wherein the image processing may include but is not limited to surround stitching, dedistortion, and artificial intelligence (AI) detection. The image processing module then sends the second image to the image fusion module, which may be used to superimpose and fuse the second image with the first image sent from the on-board host into one image, and then the system-level chip may determine the target signal based on the image and send the target signal to the vehicle screen, namely, the display screen in the display module to present the final effect.

[0041] like Figure 2 As shown, the auxiliary driving device may also include a second serializer chip (or a second serial communication chip), and the display device includes a second deserializer chip (or a second deserialization communication chip), a display control module, and a display screen. The system-level chip can also be used to send a target signal to the second serializer chip. The second serializer chip can be used to convert the target signal into a plurality of second serial signals, and transmit the plurality of second serial signals serially to the second deserializer chip. The second deserializer chip can be used to restore the received plurality of second serial signals to the target signal, and send the target signal to the display control module. The display control module can be used to control the display screen to simultaneously display the first image and the second image based on the target signal. The display control module can also be used to switch the display mode when receiving a display mode switching instruction sent by the system-level chip, for example, switching the overlay display to the partition display.

[0042] The system-level chip can also be used to send the first signal to the display device through the second serializer chip and the second deserializer chip in sequence when the first signal is received and the assisted driving start instruction is not detected (that is, the user does not have an assisted driving demand), so that the display device displays the first image based on the first signal, wherein the first signal is determined by the host based on the first image. In this way, the vehicle display system can still display the original function screen normally when the assisted driving function is not started.

[0043] The system-level chip can also be used to confirm that an assisted driving start instruction is detected when any of the following situations occurs: successfully identifying the user's assisted driving start voice, and the voice content is set according to the actual situation; receiving a first start signal issued by the display device in response to a trigger operation on the assisted driving start control, and the assisted driving start control is a virtual control set in the display area on the display screen for the user to start the assisted driving function; receiving a second start signal issued by the host in response to a trigger operation on an assisted driving button set on the vehicle, and the assisted driving button is a physical button on the vehicle, so that the user can start the assisted driving function with one click; receiving a third start signal issued by the host when detecting that the vehicle is in a reversing state, so that the user can synchronously start the assisted driving function without performing other operations when reversing, which is more convenient.

[0044] The vehicle-mounted display system solves the technical legacy problems in related technologies with simple technical methods, and can realize the superposition or partition display of large-resolution images while greatly reducing the cost.

[0045] The present disclosure also provides a vehicle, which is provided with the above-mentioned vehicle-mounted display system.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
