[0025] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0026] The following describes the in-vehicle intelligent cockpit display system, method, device, medium and program of the embodiments of the present application with reference to the accompanying drawings.
[0027] Specifically, Figure 1 A block diagram of an in-vehicle intelligent cockpit display system provided in an embodiment of the present application.
[0028] like Figure 1 As shown, the vehicle-mounted intelligent cockpit display system 10 includes: a camera group 100, a cockpit domain controller 200 and a central control screen 300.
[0029] Among them, the camera group 100 is used to collect visual data from different perspectives; the central control screen 200 includes: a large central control screen symmetrically arranged on both sides of the center console, or a center console surround integrated screen, both the large central control screen and the center console surround integrated screen include multiple display areas; a cockpit domain controller 300 with an integrated CMS chip, wherein the cockpit domain controller 300 uses the CMS chip to perform time-series synchronous splicing processing on the domain control data and the visual data from different perspectives, and transmits the domain control data and the visual data to the corresponding display areas of the large central control screen or the center console surround integrated screen through multiple low-voltage differential signal channels.
[0030] It can be understood that in the embodiment of the present application, the CMS chip can process domain control data and visual data independently on separate tracks. A failure of any signal will not affect the output of the other channel. The CMS chip synchronizes the timing of the dual signals to improve processing efficiency. The domain control data and visual data are physically isolated and transmitted to the corresponding display area through independent LVDS channels, thereby improving driving safety.
[0031] In the embodiments of this application, Figure 3As shown, each central control screen includes a first display area and a second display area. If the central control screen is the left central control screen, the first display area displays the visual data after splicing and fusion of the left camera group, and the second display area displays the left domain control data after splicing and fusion; if the central control screen includes the right central control screen, the first display area displays the right domain control data after splicing and fusion, and the second display area displays the visual data after splicing and fusion of the right camera group.
[0032] In the embodiments of this application, Figure 4 As shown, the center console's surround integrated screen includes a third display area, a fourth display area and a fifth display area, wherein the third display area displays the visual data after splicing and fusion of the left camera group, the fourth display area displays the domain control data after splicing and fusion; the fifth display area displays the visual data after splicing and fusion of the right camera group.
[0033] It can be understood that the control screen in the embodiment of the present application includes a large central control screen symmetrically arranged on both sides of the center console, or an integrated screen surrounding the center console. Among them, the large central control screens symmetrically arranged on both sides of the center console conform to the driver's natural field of vision scanning path, and can be replaced independently when a single screen fails; the integrated surround screen is formed by physical seamless splicing to form a surround curved screen, which improves the continuity of the field of vision and eliminates the visual fragmentation of traditional multi-screen segmentation.
[0034] In an embodiment of the present application, the CMS chip is independently powered and isolated from the cockpit domain controller hardware, and when the cockpit domain controller fails, the CMS chip maintains independent output of real-time visual data.
[0035] It can be understood that the design of the CMS chip in the embodiment of the present application, in which the CMS chip is independently powered and isolated from the cockpit domain controller hardware, ensures that even in the event of a failure of the cockpit domain controller, the CMS chip can still maintain independent output of real-time visual data, effectively improving the safety and system reliability of the vehicle, while ensuring that the CMS system can operate independently at critical moments, providing the driver with necessary support and protection.
[0036] In an embodiment of the present application, the central control screen 200 communicates with the CMS chip via the IIC bus to transmit touch event coordinates, and the cockpit domain controller performs interactive operations based on the coordinates.
[0037] It is understood that the embodiments of the present application communicate with the CMS chip via the IIC bus, primarily for transmitting touch event coordinate information. When a user performs a touch operation on the screen, the screen triggers an interrupt and transmits the coordinate information of the touch point. The CMS chip receives this coordinate information via the IIC bus and forwards it to the cockpit domain controller. After receiving the coordinate information, the cockpit domain controller performs the corresponding interactive operation based on the coordinates. Using the IIC bus to transmit touch event coordinates not only simplifies the system architecture and enhances system stability and security, but also improves the overall user experience.
[0038] According to the in-vehicle intelligent cockpit display system proposed in the embodiment of the present application, multi-perspective visual data and domain control data are spliced together in time sequence and then displayed in different regions, eliminating blind spots in the field of view. LVDS multi-channels independently transmit domain control data and visual data, improving anti-interference capability, eliminating independent CMS host and A-pillar screen, and hardware integration reduces overall costs. The dual-screen dynamic regional display conforms to the human eye's scanning path. Through the CMS chip's track-by-track processing + synchronous splicing of dual-channel signals, while ensuring functional safety, efficient collaboration of "multi-source data-channel-region" is achieved, thereby improving processing efficiency and driving safety.
[0039] The following will be combined Figure 2-Figure 4 The in-vehicle intelligent cockpit display system of this application is described in detail. This application integrates a CMS chip through a domain controller and uses LVDS splicing views to display the domain controller and CMS simultaneously, including the following steps:
[0040] (1) This vehicle has a central driving position, with no left or right driver or co-driver concept. The center console is symmetrically arranged with large central control screens on both sides; a surround integrated screen on the center console can also be considered.
[0041] (2) Eliminate the CMS host and A-pillar CMS display, and integrate the CMS chip into the domain controller host. The domain controller has a separate LVDS line connected to the CMS. The domain controller transmits its own display output to the CMS via LVDS. After the CMS processes and splices its own display with the domain controller's display signal, the CMS transmits the combined and processed video signal via LVDS to the display screen for display.
[0042] It should be noted that LVDS is a low-voltage differential signaling technology commonly used for high-speed, low-noise, long-distance data transmission. In video splicing, LVDS technology ensures stable signal transmission and high-quality display. The basic principle of LVDS video signal splicing is to combine image data from multiple LVDS signal sources to form a complete display. Each LVDS signal source typically contains a set of differential signal pairs, which are decoded and combined into complete image data at the receiving end. The splicing process requires ensuring signal synchronization and timing consistency to ensure seamless image continuity.
[0043] (3) The display screen is controlled by the CMS chip to turn on and off the screen. When a touch event occurs on the screen, the screen pulls the interrupt pin and sends the coordinate point. The CMS communicates with the screen through the IIC and obtains the interrupt to read the coordinate point, and then sends the coordinate point to the domain controller through the IIC with the domain controller for execution.
[0044] (4) The CSM chip can be powered independently, and the CMS can independently control power on and off and sleep. In the event of domain control failure, the CMS system will not fail, meeting the CMS functional safety requirements. In addition, the CMS controls the display output, which can also meet the regulatory requirements for CMS latency. (Latency <100ms, CMS chip can achieve <50ms)
[0045] In summary, the domain controller integrates the CMS chip, eliminating the CMS host and CMS display, significantly reducing costs for the CMS host, display, and associated wiring harnesses while freeing up structural space. The CMS display content is relocated to the center console and integrated with the domain controller content, providing users with an optimal field of view. Furthermore, the hardware separation of the CMS and domain controller meets both CMS functional safety and regulatory requirements, resulting in a more streamlined and aesthetically pleasing cockpit layout.
[0046] Next, the in-vehicle intelligent cockpit display method proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.
[0047] Figure 5 A flow chart of a vehicle-mounted intelligent cockpit display method provided in an embodiment of the present application.
[0048] like Figure 5 As shown, the vehicle-mounted intelligent cockpit display method includes the following steps:
[0049] In step S101, visual data of different perspectives and domain control data collected by a camera group are obtained.
[0050] It can be understood that the embodiment of the present application can obtain visual data and domain control data from different perspectives collected by the camera group, so as to facilitate the subsequent transmission of the spliced domain control data and visual data to the display area corresponding to the central control screen or the center console surround integrated screen through multiple low-voltage differential signal channels.
[0051] In step S102, the CMS chip is used to perform time-series synchronous splicing processing on the domain control data and the visual data of different perspectives, and the domain control data and the visual data are transmitted to the display area corresponding to the central control screen or the center console surround integrated screen through multiple low-voltage differential signal channels.
[0052] It can be understood that in the embodiment of the present application, the CMS chip can process domain control data and visual data independently on separate tracks. A failure of any signal will not affect the output of the other channel. The CMS chip synchronizes the timing of the dual signals to improve processing efficiency. The domain control data and visual data are physically isolated and transmitted to the corresponding display area through independent LVDS channels, thereby improving driving safety.
[0053] In an embodiment of the present application, the data after synchronous splicing is transmitted to the display area corresponding to the central control screen through multiple low-voltage differential signal channels, including: transmitting the visual data of the left perspective after synchronous splicing to the first display area of the left central control screen through the first low-voltage differential signal channel, and transmitting the visual data of the right perspective after synchronous splicing to the second display area of the right central control screen through the second low-voltage differential signal channel; transmitting the left domain control data after synchronous splicing to the second display area of the left central control screen through the first low-voltage differential signal channel, and transmitting the right domain control data after synchronous splicing to the first display area of the right central control screen through the second low-voltage differential signal channel.
[0054] It can be understood that the embodiment of the present application can ensure the seamless display of images on the two display screens by transmitting the visual data of the synchronously spliced left and right perspectives through independent LVDS channels to the corresponding display areas, providing the driver with continuous and clear visual information, more effective information management and display, so that key information can be presented to the user more intuitively, which not only improves the data transmission efficiency, but also increases the flexibility and scalability of the system, and enhances the user's interactive experience.
[0055] In an embodiment of the present application, the synchronously spliced data is transmitted to the display area corresponding to the center console surround integrated screen through multiple low-voltage differential signal channels, and also includes: through a third low-voltage differential signal channel, the visual data of the left and right side perspectives after synchronous splicing are respectively transmitted to the third display area and the fifth display area of the center console surround integrated screen, and the domain control data after synchronous splicing is transmitted to the fourth display area.
[0056] It is understandable that in the embodiment of the present application, when the two central control large screens are physically spliced into an integral large screen, multiple logical display areas need to be accurately mapped and controlled. By introducing the third LVDS channel, different categories of image content can be flexibly and accurately delivered to different areas of the large screen, realizing the fusion display of multi-source information under a unified picture, which not only improves the data transmission efficiency, but also increases the flexibility and scalability of the system, and enhances the user's interactive experience.
[0057] In an embodiment of the present application, it also includes: receiving a touch event interrupt signal from the central control screen through the IIC bus; the CMS chip parses the touch coordinates and forwards them to the cockpit domain controller, wherein the cockpit domain controller updates the display content of the domain control data according to the touch coordinates.
[0058] It is understood that the embodiments of the present application communicate with the CMS chip via the IIC bus, primarily for transmitting touch event coordinate information. When a user performs a touch operation on the screen, the screen triggers an interrupt and transmits the coordinate information of the touch point. The CMS chip receives this coordinate information via the IIC bus and forwards it to the cockpit domain controller. After receiving the coordinate information, the cockpit domain controller performs the corresponding interactive operation based on the coordinates. Using the IIC bus to transmit touch event coordinates not only simplifies the system architecture and enhances system stability and security, but also improves the overall user experience.
[0059] According to the in-vehicle intelligent cockpit display method proposed in the embodiment of the present application, through the technical paths of track processing, synchronous splicing, and channel transmission, it is ensured that the failure of any signal does not affect the output of another channel, thereby improving safety redundancy and ensuring pixel-level alignment of the images in each area of the dual screen, reducing overall costs and improving user experience.
