[0023] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the ways in which this application may be implemented. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] In the following description, the expression “some embodiments” is used, which describes a subset of possible embodiments. However, it should be understood that “some embodiments” can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0026] If opaque physical displays such as LCDs and LEDs are used as the visual interaction medium in driver assistance systems to display driver assistance information needed for safe driving, increasing the size of the display will inevitably increase the obstruction of the driver's view. Furthermore, these opaque displays generally have a certain width of bezel, which not only fails to provide effective driver assistance information but also further obstructs the driver's view. While using a head-up display (HUD) to show driver assistance information offers some improvement in terms of obstructing the driver's view compared to a solid, opaque display, the semi-transparent reflective film used in HUDs reduces this. However, HUDs require multiple optical refractions to display information, necessitating high brightness and resulting in lower resolution. This limits the display to simple graphics and images, hindering the provision of richer driver assistance information. Furthermore, achieving a good user experience requires calibration to position the HUD for optimal driver comfort and visibility, complicating operation and failing to meet the individual needs of different drivers. Therefore, neither traditional solid displays nor HUDs can simultaneously satisfy the demands for driving safety and user comfort. Based on this, the inventors of this application provide a driver assistance system that effectively reduces driver obstruction while providing richer and more effective driver assistance information.

[0027] Please see Figure 1The diagram shows a data flow diagram of an assisted driving system provided according to some embodiments of this application. In some embodiments, the assisted driving system provided by this application includes a sensing module 1 and a transparent display module 2. The transparent display module 2 includes a host 21 and a transparent display screen 22 electrically connected to the host 21, and the host 21 is connected to the sensing module 1. The sensing module 1 is used to collect environmental information data of the vehicle's driving environment and send the environmental information data to the host 21. The host 21 is used to control the transparent display screen 22 to display assisted driving information for the driver to observe based on the received environmental information data. As an optional implementation, the transparent display screen 22 may be, but is not limited to, an OLED transparent display screen, an LED transparent display screen, and an LCD transparent display screen.

[0028] Sensing module 1 is installed on the vehicle to collect environmental information data about the vehicle's driving environment. This environmental information data includes, but is not limited to, image information and / or 3D information of the driving environment. After collecting the environmental information data, sensing module 1 sends it to host 21. Host 21 processes the environmental information data to obtain an environmental perception result, and then, based on the environmental perception result and the vehicle's own state information, performs an environmental cognition result. This environmental cognition result is then sent as driver assistance information to transparent display screen 22 for display. Furthermore, host 21 also sends environmental information data and / or environmental perception results as driver assistance information to transparent display screen 22 for display.

[0029] The environmental perception results include the perception results obtained by the host 21 from perceiving target objects in the driving environment of the main vehicle, including information such as the category, location, and size of the target objects. The environmental cognition results include the host 21's cognition of target objects in the surrounding environment based on the perceived target object information (environmental perception results) and the main vehicle's own state information, in order to determine whether there are currently risky target objects in the surrounding environment, whether target objects that require warning, or whether target objects that require prompting, etc.

[0030] The host 21 can perform inference target recognition on the acquired environmental information data based on the running deep learning algorithm model, so as to transform the environmental information data into environmental perception results, and then obtain environmental cognition results based on the environmental perception results and the vehicle's own state, thereby determining the safety level of the current driving environment.

[0031] The assisted driving system provided in this application embodiment uses a transparent display screen 22 to display assisted driving information, which can effectively avoid obstruction of the driver's line of sight and improve the driving safety performance of the main vehicle. Simultaneously, based on environmental information data controlled by the host 21, the display of the transparent display screen 22 is high-resolution and requires no calibration, making it simple to use. Therefore, the assisted driving system provided in this application embodiment can effectively avoid obstruction of the driver's line of sight and provide the driver with richer and more effective assisted driving information, thus providing a better driving experience and effectively improving the driving safety of the main vehicle.

[0032] In some embodiments, the transparent display screen 22 is a borderless transparent display screen. Specifically, as an optional implementation, the transparent display screen 22 can be fixed to the host 21 by a screen fixing bracket. Furthermore, the display surface of the transparent display screen 22 faces the user, and transparent protective glass is bonded to the front and back of the transparent display screen using optical adhesive. The transparent display screen 22 has no borders on the left, right, and top edges, resulting in an aesthetically pleasing appearance, while the bottom edge is fixed to the host 21 using the screen fixing bracket. In the assisted driving system provided in this application embodiment, the imaging panel of the transparent display screen 22 is completely transparent when not displaying auxiliary information, and its edges have no wide borders, greatly reducing the obstruction of the field of vision caused by the display screen borders, while also improving the aesthetics of the transparent display screen 22.

[0033] In some embodiments, the transparent display screen 22 has a touch area for collecting user commands. In this embodiment, the transparent display screen 22 is a touch-enabled transparent display screen. The user inputs corresponding commands based on touch input on the transparent display screen, and the transparent display screen 22 then sends the user commands input via the touch area to the host computer 21. The host computer 21 controls the transparent display screen 21 to display corresponding driver assistance information according to the user commands. Human-computer interaction is achieved based on the touch area, displaying driver assistance information that meets the user's needs according to user commands, thus improving user comfort and driving safety.

[0034] Please see Figure 2The diagram shows a schematic of an assisted driving system structure provided according to some embodiments of this application. In some embodiments, the transparent display module 2 further includes a connector 23. The transparent display screen 22 is connected to the host 21 via the connector 23 and can be folded relative to the host 21. The transparent display screen 22 is supported in a corresponding position inside the vehicle body with the host 21 as a support base. Based on the connector 23, the transparent display screen 22 can be folded relative to the host 21, that is, opened and closed relative to the host 21. The transparent display screen 22 is pivotally connected to the host 21 via the connector 23, that is, the transparent display screen 22 can rotate relative to the host 21 and be fixed in a corresponding rotation position. According to the user's preference, the transparent display screen 22 can be folded flat when not needed, and when it is necessary to display assisted driving information based on the transparent display screen 22, the transparent display screen 22 can be opened and erected so that the display surface of the transparent display screen 22 faces the user for easy observation.

[0035] Please continue reading. Figure 2 As shown, in some embodiments, the assisted driving system further includes a data line 3 connecting the host 21 and the sensor module 1. The host 21 obtains environmental information data from the sensor module 1 based on the data line 3. Specifically, the host 21 is provided with a data interface. One end of the data line 3 is connected to the sensor module 1, and the other end is inserted into the data interface of the host 21 to realize data transmission between the host 21 and the sensor module 1. The implementation method is simple.

[0036] In other embodiments, the host 21 can also acquire environmental information data from the sensor module 1 via wireless transmission. The wireless transmission method includes Bluetooth or WiFi. Specifically, both the host 21 and the sensor module 1 have corresponding wireless transmission units, enabling wireless transmission between them. The wireless connection between the host 21 and the sensor module 1 eliminates the need for wiring, resulting in a neat appearance and easy maintenance.

[0037] Please continue reading. Figure 2 As shown, in some embodiments, the sensing module 1 includes a first housing 11 and an infrared sensor 12 disposed within the first housing. The infrared sensor 12 is connected to the host 21 and is used to collect infrared image data of the vehicle's driving environment and send the infrared image data to the host 21. The information collected by the infrared image sensor is not affected by ambient light, making it convenient to collect effective environmental information data even in poor visibility conditions, so as to obtain auxiliary driving information that is beneficial to improving driving safety performance and display it on the transparent display screen 22. In some embodiments, the infrared sensor 12 is specifically an infrared thermal imager.

[0038] Furthermore, such as Figure 2As shown, in some embodiments, the host 21 includes a second housing 211 serving as a support base and an SOC (System on Chip) system 212 disposed within the second housing 211. The SOC system 212 is electrically connected to the sensing module 1 and the transparent display screen 21 to receive environmental information data and control the transparent display screen 22 to display assisted driving information based on the environmental information data. Using the SOC system as the main control system of the host 21 helps to reduce the cost of the assisted driving system and improve its reliability. Furthermore, to increase the stability of the host 21 when placed in the corresponding position, the side of the second housing 211 away from the transparent display screen 22 is provided with an adhesive layer or suction cup structure. Figure 2 (Illustrative image shown) The transparent display module 2 is fixed to a corresponding position inside the vehicle body based on an adhesive layer or suction cup structure. This corresponding position may be, but is not limited to, above the dashboard of the vehicle body. The adhesive layer can be repeatedly applied, and its adhesion should satisfy the following conditions: it should both fix the main unit 21 to the corresponding position and allow the driver to easily detach the main unit 21 from the corresponding position as needed.

[0039] In some embodiments, the sensing module 1 further includes a visible light sensor, which can be integrated together with the infrared sensor in the first housing 11, or integrated in the second housing 211 of the host 21. The host 21 obtains environmental perception and cognitive results of the vehicle based on the infrared image data collected by the infrared sensor 12 and the visible light image data collected by the visible light sensor, thereby obtaining more accurate and effective information. More driver assistance information is displayed on the transparent display screen 22 for the user to observe, further improving the driving safety performance of the vehicle. The driver assistance information displayed on the transparent display screen 22 includes, but is not limited to, images, text, and / or graphics.

[0040] Furthermore, in some embodiments, in order to obtain distance information of target objects in the driving environment of the main vehicle, the sensing module 1 also includes a distance sensor. The distance sensor, infrared sensor 12 and visible light sensor are integrated together in the first housing 11, and the positional relationship of the infrared sensor 12, visible light sensor and ranging sensor in the first housing 11 is relatively fixed. The host 1 fuses the environmental information data obtained by multiple sensors in the sensing module 1 to obtain more accurate assisted driving information, which effectively improves driving safety.

[0041] In some embodiments, the driver assistance system further includes microphones connected to the host 21. The microphones collect voice commands and send them to the host 21, enabling the host 21 to control the transparent display screen 22 according to the voice commands, such as controlling the transparent display screen 22 to display corresponding driver assistance information and / or controlling the on / off state of the transparent display screen 22. By collecting user voice commands through the microphones and controlling the transparent display screen 22 to display driver assistance information that meets the user's needs, the interaction performance between the driver assistance system and the user is further enhanced, improving the user experience and driving safety.

[0042] Furthermore, the driver assistance system also includes a speaker connected to the host unit 21. The host unit 21 controls the speaker to play corresponding prompts or control the speaker's on / off state based on voice commands collected by the microphone. The microphone and / or speaker can be specifically integrated into the host unit, which helps reduce the space occupied by the driver assistance system. In addition, in other embodiments, the driver assistance system may also include a non-contact gesture sensing module. Based on the non-contact gesture sensing module, the system collects the user's non-contact gestures and converts them into corresponding control commands to control the transparent display screen 22 to display corresponding driver assistance information, further enhancing the human-computer interaction of the driver assistance system. In addition, the driver assistance system may also include a light-emitting alarm module connected to the host unit 21. The host unit 21 controls the light-emitting alarm module to emit a light alarm when the danger level of the vehicle's driving environment meets preset conditions, in order to alert the driver and improve driving safety.

[0043] In summary, the driver assistance system provided in this application uses a transparent display screen to show driver assistance information, avoiding unnecessary obstruction of the driver's view, thus providing a better user experience and improving driving safety. Furthermore, the use of a borderless transparent display screen effectively optimizes the aesthetic loss caused by the presence of display borders. Additionally, the driver assistance system eliminates the need for cumbersome optical axis calibration, and the image display offers a more engaging user experience.

[0044] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
