Description

Technical Field

[0001] This invention relates to vehicle-mounted HUDs, and more particularly to a load optimization method, system, and storage medium for a projection-type HUD system. Background Technology

[0002] With the rapid development of in-vehicle intelligence, wireless screen projection has become one of the core functions of in-vehicle HUD products. Users can project navigation, entertainment, and vehicle status images onto the HUD display screen using mobile devices such as smartphones and tablets, achieving a convenient experience of viewing relevant information without having to look down.

[0003] Currently, existing wireless screen mirroring HUD products all employ a full-screen image data transmission mode during screen mirroring. This means the mobile terminal transmits the entire screen's image data to the HUD via a wireless link, where it is then decoded, rendered, and displayed. However, this transmission mode has significant technical drawbacks: because HUD screen mirroring requires the real-time transmission of a large amount of continuous image pixel data, and wireless transmission bandwidth is limited, the processor load on both the mobile terminal and the HUD increases dramatically. This manifests as device lag, screen mirroring latency, and increased power consumption, and in severe cases, image distortion and screen mirroring interruptions. Furthermore, the resource allocation between the HUD and the mobile terminal is unreasonable; when one party lacks sufficient resources, screen mirroring lag is further exacerbated, impacting the user experience. More importantly, existing technology does not take into account the display characteristics of HUDs, still transmitting full-screen data including a large amount of invalid background data, resulting in a significant amount of invalid data transmission and further increasing the system load.

[0004] In existing technologies, optimizations for in-vehicle projection mainly focus on increasing the bandwidth of the transmission link or improving image compression algorithms. However, these solutions do not reduce the amount of invalid data at the root of data transmission, nor do they consider the resource coordination and allocation between the HUD and the mobile terminal. They cannot completely solve the problem of excessive system load during projection and will increase hardware costs or reduce image display quality. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a method, system, and storage medium for optimizing the load of a projection-type HUD system by reducing invalid data transmission, achieving resource collaborative allocation between the HUD and the mobile terminal, and reducing system load while ensuring the display effect of the HUD.

[0006] Technical solution: The load optimization method for a projection-type HUD system described in this invention is characterized by comprising the following processes:

[0007] The HUD display screen is divided into multiple areas, including at least one basic information display area and at least one dynamic projection display area. The basic information display area also serves as a resource buffer.

[0008] The system resource status of the HUD and mobile terminal is monitored in real time. Based on the monitored system resource status, the display mode of the basic information display area is switched between displaying the HUD's self-built map and displaying it by screen projection from the mobile terminal.

[0009] The system dynamically selects the valid UI display areas within the dynamic projection display area and marks the non-UI display areas; it only transmits image data for the valid UI display areas, while the HUD displays the non-UI display areas in monochrome.

[0010] The display refresh rate of at least one of multiple areas is dynamically adjusted based on the vehicle's driving scenario.

[0011] By dividing the HUD display into a basic information display area and a dynamic projection display area, and using the basic information display area as a resource buffer, resource reservation and flexible scheduling are achieved. By monitoring the system resource status of the HUD and mobile terminal in real time, the display mode of the basic information display area is dynamically switched (either by the HUD's self-built image or by the mobile terminal's projection), enabling collaborative task allocation between the HUD and the mobile terminal and avoiding overload on a single device. By dynamically selecting effective UI display areas and marking non-UI display areas, only transmitting image data from effective areas and filling non-UI areas with monochrome, the amount of invalid image data transmitted is significantly reduced, resulting in a significant decrease in processor utilization and bandwidth usage. By dynamically adjusting the display refresh rate of different areas according to the vehicle driving scenario, scene-adaptive load optimization is achieved, ensuring the smooth display of core information while maximizing the saving of system resources and power consumption. The synergistic effect of these technologies effectively solves the problem of excessive load in existing wireless projection HUD systems, achieving dynamic balancing and on-demand allocation of system resources. While ensuring display quality, it significantly reduces data transmission volume and processor load, improving projection smoothness and user experience.

[0012] Preferably, when the load on the HUD MCU exceeds a preset threshold, the display mode of the basic information display area is switched to screen projection from the mobile terminal; when the resource usage of the mobile terminal exceeds a preset threshold or the battery level is lower than a preset threshold, the display mode of the basic information display area is switched to display of the HUD's self-built image.

[0013] By setting specific switching trigger conditions, precise control of resource collaboration between the HUD and mobile terminal is achieved, ensuring that the resource-constrained party can promptly transfer tasks to the resource-sufficient party, thus guaranteeing the smooth operation of the overall system.

[0014] Preferably, the non-UI display area is the black background area in the HUD projection display UI, and the monochrome fill display is the black fill display.

[0015] By limiting the non-UI display area to a black background and setting the monochrome fill to black, the UI design characteristics of the large amount of pure black background of the HUD display are fully utilized, ensuring a seamless transition of the display effect while reducing data transmission.

[0016] As a preferred option, dynamically adjusting the display refresh rate according to the vehicle driving scenario specifically includes: presetting multiple refresh rate levels, and configuring different refresh rate levels for multiple areas according to the vehicle driving scenario.

[0017] By presetting multiple refresh rate levels and configuring different levels for different areas, fine-grained refresh rate management is achieved, making refresh rate adjustment more flexible and controllable.

[0018] Preferably, the HUD display screen is divided into three areas, including a vehicle information display area, a navigation display area, and an entertainment display area.

[0019] By dividing the HUD display into three specific areas—vehicle information display, navigation display, and entertainment display—a clear partitioning basis is provided for subsequent scenario-based refresh rate adjustments, facilitating differentiated optimization based on the functional importance of different areas.

[0020] Preferably, the vehicle driving scenarios include highway scenarios, urban traffic jam scenarios, and stationary entertainment scenarios. In highway scenarios, the vehicle information display area and navigation display area are configured with a first refresh rate, and the entertainment display area is configured with a third refresh rate. In urban traffic jam scenarios, the vehicle information display area and navigation display area are configured with a second refresh rate, and the entertainment display area is configured with a third refresh rate. In stationary entertainment scenarios, the vehicle information display area is configured with a third refresh rate, the navigation display area switches to cached data display, and the entertainment display area is configured with a first refresh rate. The values ​​of the first, second, and third refresh rates decrease sequentially.

[0021] By configuring different regional refresh rate combinations for high-speed scenarios, urban traffic jam scenarios, and static entertainment scenarios, scenario-adaptive and refined load optimization is achieved: ensuring the real-time nature of driving safety-related information in high-speed scenarios, reducing power consumption while ensuring entertainment experience in static entertainment scenarios, and balancing information updates and resource consumption in urban traffic jam scenarios, thus taking into account driving safety, user experience, and system energy saving.

[0022] The screen-projection HUD system load optimization system of the present invention includes:

[0023] The area division unit is used to divide the HUD display screen into multiple areas, including at least one basic information display area and at least one dynamic projection display area. The basic information display area also serves as a resource buffer. It is also used to dynamically select the valid UI display partitions in the dynamic projection display area and mark the non-UI display partitions.

[0024] The resource detection unit is used to monitor the system resource status of the HUD terminal and mobile terminal in real time.

[0025] The data transmission unit is used to transmit only the image data of the effective UI display partition;

[0026] The display control unit is used to control the display mode of the basic information display area to switch between displaying a custom HUD image and displaying a mobile terminal projection image, based on the system resource status monitored by the resource detection unit; it is also used to fill non-UI display areas with monochrome display, and to dynamically adjust the display refresh rate of at least one of multiple areas according to the vehicle driving scenario.

[0027] Preferably, the non-UI display area is the black background area in the HUD projection display UI, and the monochrome fill display is the black fill display.

[0028] Preferably, the display control unit presets multiple refresh rate levels and configures different refresh rate levels for each area according to the vehicle driving scenario.

[0029] The computer-readable storage medium for storing one or more programs according to the present invention is characterized in that: the one or more programs include instructions that, when executed by a computing device, cause the computing device to perform any of the methods described above.

[0030] Beneficial effects: Through the coordinated optimization of regional division and resource collaboration, UI partition transmission optimization and scene adaptive refresh rate adjustment, the problem of excessive load in existing wireless projection HUD systems is effectively solved. Dynamic balance and on-demand allocation of system resources are achieved. While ensuring display effect, the amount of data transmission and processor load are significantly reduced, the smoothness of projection and user experience are improved, and no additional hardware cost is required.

[0038] As shown in the figure, the load optimization method for the projection-type HUD system of the present invention is characterized by including the following processes:

[0039] The HUD display screen is divided into multiple areas, including at least one basic information display area and at least one dynamic projection display area. The basic information display area also serves as a resource buffer. The HUD display screen can be divided into three areas, including a vehicle information display area, a navigation display area, and an entertainment display area. The vehicle information display area is the basic information display area, and the other two areas are dynamic projection display areas.

[0040] The system resource status of the HUD and mobile terminal is monitored in real time. Based on the monitored system resource status, the display mode of the basic information display area is switched between displaying the HUD's self-built map and displaying it by screen projection from the mobile terminal.

[0041] When the load on the HUD MCU exceeds a preset threshold, the display mode of the basic information display area is switched to screen projection from the mobile terminal; when the resource usage of the mobile terminal exceeds a preset threshold or the battery level is lower than a preset threshold, the display mode of the basic information display area is switched to display of the HUD's self-built image.

[0042] The system dynamically selects the valid UI display areas within the dynamic projection display area and marks the non-UI display areas; it only transmits image data for the valid UI display areas, while the HUD displays the non-UI display areas with monochrome fill; the non-UI display areas are the black background areas in the HUD projection UI, and monochrome fill displays are black fill displays.

[0043] The display refresh rate of at least one of multiple areas is dynamically adjusted according to the vehicle driving scenario;

[0044] The dynamic adjustment of the display refresh rate based on the vehicle driving scenario specifically includes: preset multiple refresh rate levels, and configuring different refresh rate levels for multiple areas according to the vehicle driving scenario.

[0045] The vehicle driving scenarios include highway scenarios, urban traffic jam scenarios, and stationary entertainment scenarios. In highway scenarios, the vehicle information display area and navigation display area are configured with the first refresh rate, and the entertainment display area is configured with the third refresh rate. In urban traffic jam scenarios, the vehicle information display area and navigation display area are configured with the second refresh rate, and the entertainment display area is configured with the third refresh rate. In stationary entertainment scenarios, the vehicle information display area is configured with the third refresh rate, the navigation display area switches to cached data display, and the entertainment display area is configured with the first refresh rate. The values ​​of the first, second, and third refresh rates decrease sequentially.

[0046] The screen-projection HUD system load optimization system of the present invention includes:

[0047] The area division unit is used to divide the HUD display screen into multiple areas, including at least one basic information display area and at least one dynamic projection display area. The basic information display area also serves as a resource buffer. It is also used to dynamically select the valid UI display partitions in the dynamic projection display area and mark the non-UI display partitions.

[0048] The resource detection unit is used to monitor the system resource status of the HUD terminal and mobile terminal in real time.

[0049] The data transmission unit is used to transmit only the image data of the effective UI display partition;

[0050] The display control unit is used to control the display mode of the basic information display area to switch between displaying a custom HUD image and displaying a mobile terminal projection image, based on the system resource status monitored by the resource detection unit; it is also used to fill non-UI display areas with monochrome display, and to dynamically adjust the display refresh rate of at least one of multiple areas according to the vehicle driving scenario.

[0051] The present invention provides a computer-readable storage medium for storing one or more programs, wherein the one or more programs include instructions that, when executed by a computing device, cause the computing device to perform the method described above.

[0052] To better illustrate the invention, the following example uses a car WiFi / Bluetooth projection HUD product with a resolution of 1424×280 and a UI design featuring a large number of pure black backgrounds, which is suitable for various scenarios such as mobile phone projection navigation and in-car entertainment.

[0053] I. System Structure

[0054] The optimization system provided by this invention includes a region division unit, a resource detection unit, a data transmission unit, and a display control unit. These units can be integrated into the vehicle-mounted HUD main unit and the mobile terminal.

[0055] In this embodiment, the core of the vehicle-mounted HUD is equipped with a GC9005-B200A / I chip. This chip integrates a dual-core RISC-VNUCLEI®-N607 processor (400MHz), 16KB ICache + 16KB DCache / core, 112KB TCM RAM, and 32MB on-chip DDR1 memory, serving as the core control unit of the HUD. The display screen is 5.5 inches in size with a fixed resolution of 1424×280. It connects to the display screen via the chip's built-in LVDS interface, supports RGB888 display format, and the display signal is directly output from the DISPLAY unit of the GC9005-B200A / I chip. It includes built-in WiFi (802.11n) and Bluetooth 5.0 receiver modules, expanded through the chip's SPI / I2C communication interface. The storage unit has a capacity of 16GB and connects to the storage unit via the chip interface. It supports connection to the vehicle's OBD interface, allowing the chip to directly read vehicle information such as vehicle speed, gear position, and engine speed. The HUD display features a UI design with a predominantly pure black background, and the chip supports an operating temperature range of -40°C to +85°C to suit various scenarios.

[0056] Mobile terminals are compatible with smartphones or tablets, all supporting WiFi 802.11n and Bluetooth 5.0. They are compatible with the WiFi / Bluetooth transmission unit of the HUD chip and can be equipped with navigation apps (Gaode Navigation, Baidu Navigation) and entertainment apps (NetEase Cloud Music) to generate screen projection image data. They can automatically adapt to the HUD resolution and generate image data (below 1080P30) in H264 decoding format compatible with the GC9005-B200A / I chip, ensuring that the data can be directly decoded by the chip after being transmitted to the HUD, reducing the load on the HUD end. At the same time, they are compatible with black background UI to reduce the generation of invalid data.

[0057] The area division unit is fully integrated into the GC9005-B200A / I chip, utilizing the chip's own AHMI-V3@400MHz graphics acceleration engine to implement the area division function. This unit is used to divide the HUD display into multiple areas. For example, Figure 2 As shown, the area division unit can divide the HUD display screen into three areas: left, center, and right. The left side is the vehicle information display area, which also serves as a system resource buffer; the center area is the navigation area; and the right side area is the entertainment area. In addition, this unit is also used to dynamically select valid UI display partitions (such as...) within the dynamic projection display area. Figure 5 The small boxes in the image are used to mark non-UI display partitions. The partition calculation process is completed independently by the chip's graphics acceleration engine, relying on the chip's own DramCache unit to cache partition data and improve partitioning efficiency.

[0058] The resource detection unit is integrated into the GC9005-B200A / I chip at the HUD end. Through the chip's built-in clock control register and system control module, it monitors the real-time utilization of the chip's dual-core processor and 32MB of on-chip DDR1 memory, and can preset resource utilization thresholds (e.g., 80%). The resource buffer area is implemented using the chip's own 112KB TCMRAM, with a preset buffer reservation ratio of 15%-20% and a lower buffer limit of 5%. This unit can also simultaneously monitor bandwidth usage during image data transmission, as well as the load status of the chip's decoder and graphics acceleration engine. The detection data is directly fed back to the chip processing unit. The mobile terminal integrates a resource detection program to simultaneously monitor its own resource status (such as battery level and processor / memory utilization), and interacts with the HUD chip via a WiFi / Bluetooth transmission module.

[0059] The data transmission unit is integrated within the GC9005-B200A / I chip at the HUD end, utilizing the chip's own SPI / I2C communication interface and DMA controller to achieve data transmission. This unit integrates an optimized transmission program, supporting "coordinate + pixel value" transmission mode and frame interpolation compensation algorithm. The transmission link employs dual-mode Bluetooth 5.0 and WiFi, implemented through the chip's extended WiFi / Bluetooth transmission unit. WiFi is prioritized for transmitting large amounts of image data (such as H.264 format image data), while Bluetooth transmits control commands. This unit is used to transmit image data only for valid UI display areas, reducing invalid data in black background areas. Transmission rate adjustment is handled by the chip's own control unit. The mobile terminal integrates a corresponding transmission program, generating image data compatible with the GC9005-B200A / I chip's decoding, enabling efficient data interaction with the HUD chip.

[0060] The display control unit is integrated into the GC9005-B200A / I chip, utilizing the chip's own Display unit and AHMI graphics acceleration engine to implement display control functions. This unit controls the display mode of the basic information display area, switching between HUD-created image display and mobile terminal projection display based on the monitoring results of the resource detection unit. For example, when the HUD-side MCU load exceeds a preset threshold, the basic information display area is switched to mobile terminal projection display; when the mobile terminal resource usage exceeds a preset threshold or the battery level is below a preset threshold, the basic information display area is switched to HUD-created image display. This unit is also used for monochrome fill display of non-UI display areas, such as filling areas marked with a black background with black, blending it with the original black background of the HUD. Furthermore, this unit is used to dynamically adjust the display refresh rate of at least one area among multiple areas according to the vehicle driving scenario; the refresh rate adjustment is accomplished by the chip's clock control register.

[0061] II. Optimization Method Implementation Steps

[0062] 1. Dynamic region split-screen collaborative display method

[0063] This method achieves system resource balance through region division, resource detection, and task transfer.

[0064] First, in the area division step, the HUD display screen is divided into three areas: the left side is the vehicle information display area (which also serves as a system resource buffer), the middle is the navigation area, and the right side is the entertainment area.

[0065] In the resource detection step, the system resource status of the HUD terminal and the mobile terminal is monitored in real time.

[0066] When the HUD-side MCU load is too high (for example, the resource detection step detects that the HUD-side MCU load exceeds a preset threshold of 80%, and the remaining resources in the buffer area drop to 3%), the display mode of the left vehicle information display area is switched from HUD-created map display to mobile terminal projection display. The data transmission unit sends this command, and the mobile phone receives OBD data via Bluetooth and synchronously projects it to the left buffer. After the switch, the HUD-side MCU load is reduced by 18%, dropping to 65%.

[0067] When the mobile device has low battery (e.g., the phone's battery drops to 18%, below the 20% threshold), to ensure battery life, the left-side vehicle information display area is switched to a custom HUD map display. The phone stops transmitting vehicle information, only transmitting core data from the central navigation area and necessary data from the right-side entertainment area. Simultaneously, the phone's buffer area is adjusted to 20% to reduce non-core task usage and lower power consumption. After optimization, phone power consumption is reduced, while screen mirroring remains smooth.

[0068] 2. Optimization methods for dynamic selection of UI partitions and data transmission

[0069] This method reduces invalid data transmission by dynamically selecting valid UI areas and optimizing the transmission protocol.

[0070] Taking mobile navigation screen mirroring as an example, the navigation application is run on the phone in portrait mode and then mirrored to the HUD in landscape mode. The area division unit is identified in real time, and the effective UI area of ​​the navigation (such as navigation route, destination, turn arrow, etc.) is dynamically selected. The blank areas on the left and right sides (each 162×280 pixels) within the dynamic screen mirroring display area are marked as non-UI display areas (blended with the original black background of the HUD).

[0071] The mobile phone's data transmission module optimizes the WiFi transmission protocol, first transmitting the pixel coordinates of the effective UI area to the HUD, and then transmitting the H264 format pixel value data within that area, adapting to the H264 decoding characteristics of the GC9005-B200A / I chip.

[0072] The display control unit fills all non-UI display areas with black, seamlessly blending with the original black background of the HUD. After optimization, data transmission volume is significantly reduced, and processor usage and projection latency are both noticeably lowered.

[0073] 3. Method for dynamically adjusting refresh rate by region and scene

[0074] This method first defines three refresh rate standards: high, medium, and low (e.g., high refresh rate 18 frames / second, medium refresh rate 10 frames / second, and low refresh rate 3 frames / second), and then adjusts the refresh rate of each region differently according to three scenarios: vehicle stationary entertainment, urban traffic jam, and highway.

[0075] In stationary entertainment scenarios (e.g., in Park mode, at 0 km / h), the display control unit adjusts according to preset rules: the refresh rate of the left-hand vehicle information area is reduced to a low refresh rate (3 frames / second), the middle navigation area switches to cached data display with minimal updates, and the right-hand multimedia entertainment area maintains a high refresh rate (18 frames / second) and adopts a non-full UI update strategy (i.e., the black background area is not updated). After adjustment, data transmission volume is reduced, multimedia display is smooth, and system power consumption is reduced.

[0076] In urban traffic jams (e.g., vehicle speeds below 30 km / h), the display control unit adjusts according to preset rules: the left-side vehicle information area and the middle navigation area use a medium refresh rate (10 frames / second), while the right-side multimedia entertainment area switches to a low refresh rate (3 frames / second). The multimedia area uses light compression for transmission, ensuring lossless transmission of core data. After adjustment, core information updates promptly, multimedia display exhibits no noticeable lag, and system load is reduced.

[0077] In high-speed scenarios (e.g., vehicle speeds exceeding 60 km / h), the display control unit adjusts according to preset rules: the left-side vehicle information area and the middle navigation area both use a high refresh rate (18 frames / second), while the right-side multimedia entertainment area switches to a low refresh rate (3 frames / second), employing a frame interpolation compensation algorithm to ensure smooth, lag-free display of core information. After adjustment, vehicle information and core navigation information are highly real-time, meeting the safety requirements of high-speed driving, and the system load remains within a reasonable range.
