[0002] With the development of technology, there are many AVM (Around View Monitor) systems suitable for vehicles on the market, as well as further assembled advanced driver assistance systems (ADAS, Advanced Driver Assistance System), which can assist drivers in observing visual blind spots while driving, and can even automatically judge and warn, reminding drivers to pay attention or be alert, thereby reducing the chance of accidents.

[0003] However, in reality, traffic accidents caused by visual blind spots are still emerging in an endless stream, especially in large vehicles such as buses, large trucks, gravel trucks, and even container trucks and articulated trucks. This is not only because the driver's seat is high and the body is long, resulting in more blind spots on the side and rear, but also because of factors such as long wheelbase and large turning radius. What's more, modern drivers, in addition to paying attention to the condition of the vehicle, road conditions, turns, traffic lights, etc. in front, need to observe the monitoring screens of many visual blind spots from time to time, and even the condition of the passengers in the car and the cargo condition of the car itself (such as cold chain, special, and dangerous goods). They are too busy and easily ignore the changes around the car, resulting in no extra time and ability to pay attention to the approach of other objects and dodge, slow down or stop. This is also an important reason why although there are regulations on installing cameras or active detection function equipment, it has not been able to effectively reduce the occurrence of accidents.

[0004] In view of this, the inventor of this case has studied and improved this method, and finally completed this utility model after continuous attempts and efforts. Utility Model Content

[0025] The vehicle display device 1 has a body 10 that can be assembled with a bracket assembly 20 so that it can be supported at a suitable position in the vehicle. The body 10 includes a front shell 11 and a rear shell 18 that can be relatively joined and form a space therebetween to accommodate other components.

[0026] In this embodiment, the main body 10 is provided with a circuit substrate 14 between the front shell 11 and the rear shell 18, and includes a display screen 12 and an orientation warning module 13 disposed on the circuit substrate 14. The display screen 12 is used to cooperate with the driving assistance system 3 to display appropriate images or information, is disposed on the front side of the circuit substrate 14, and can be accommodated in a hollow portion 111 opened at a relative position of the front shell 11 to be exposed on the front side of the main body 10; the orientation warning module 13 is arranged around the display screen 12, and is mainly used to emit warning lights at appropriate positions around the display screen 12 under the instruction of the driving assistance system 3. The orientation warning module 13 at least includes a plurality of light-emitting units 131, and the plurality of light-emitting units 131 are arranged around the display screen 12 at intervals.

[0027] The processing unit 30 of the driving assistance system 3 is usually a vehicle-specific microcontroller ECU (Eletronic Control Unit), which is electrically connected to the multiple camera units 40 and the vehicle display device 1, respectively, to receive the real scene images obtained by the multiple camera units 40 for related image processing, analysis and calculation, and judgment according to preset conditions, and then output a signal that can control the vehicle display device 1. The processing unit 30 can be equipped with multiple functional modules according to practical needs, and in this example, it can be generally defined as an image processing module 31, an object recognition module 32, a trajectory prediction module 33, a warning judgment module 34 and a display control module 35, but is not limited thereto.

[0028] The image processing module 31 can use the plurality of real-scene images to perform image processing operations such as image stitching, projection, distortion conversion, etc., and can at least stitch and convert a bird's-eye view of the vehicle's surrounding image. The object recognition module 32 can identify objects (such as pedestrians, vehicles, bicycles, small animals, etc.) around the vehicle 60 from the plurality of real-scene images or images processed by the image processing module 31. The trajectory prediction module 33 can track the past image data of the object to infer its past movement path C, and estimate the movement trajectory D of the object at a predetermined time in the future based on the movement path C (which can be used in conjunction with the reference Figure 5 or Figure 7 ), in simple terms, the movement change of each frame of image can be used to predict the next possible direction, and the direction can be linked to form a trajectory. The warning judgment module 34 can determine whether to issue a warning based on the distance of the object. When the distance between the object and the vehicle body 60 is less than a preset warning distance, a warning is issued, and when issuing a warning, the vehicle display device 1 can drive the one or more light-emitting units 131 at the corresponding position around the display screen 12 to emit a warning light according to the position of the object relative to the vehicle body 60. The display control module 35 can coordinate the warning to adjust the image or information displayed on the display screen 12 of the vehicle display device 1, so that the display screen 12 can display some images or information that are easy for the driver to identify when issuing a warning, such as a real-life image containing the object at the corresponding position, or a real-life image of the object partially enlarged at the corresponding position, or an electronic image (icon) that can represent the object.

[0029] Through the cooperation of the processing unit 30 and the vehicle display device 1 in the above-mentioned driving assistance system 3, the driving assistance system 3 can identify objects approaching around the vehicle body 60, and then track and judge to issue a warning. When issuing a warning, a signal can be used to drive the display screen 12 of the vehicle display device 1 to cooperate in displaying the image or information of the approaching object, and the position warning module 13 can emit a warning light according to the position of the approaching object relative to the vehicle body 60, and the one or more light-emitting units 131 at the corresponding position around the display screen 12.

[0030] In a feasible embodiment, the driving assistance system 3 may also include a plurality of sensing units 50 disposed on the vehicle body 60 for sensing objects around the vehicle body 60. The processing unit 30 can receive sensing signals from the plurality of sensing units 50 for comparison and correction with the identified objects, so that the driving assistance system 3 can more accurately identify or track objects around the vehicle body 60.

[0031] In this embodiment, the plurality of light emitting units 131 are assembled on the circuit substrate 14 and surround the display screen 12. The front housing 11 is provided with a plurality of hollow guide grooves 112 at positions corresponding to the plurality of light emitting units 131. The plurality of guide grooves 112 are arranged around the hollow portion 111 at intervals, so that the warning lights of the plurality of light emitting units 131 can be emitted forward along the corresponding guide grooves 112. The warning lights emitted by the plurality of light emitting units 131 are preferably red, yellow or blue.

[0032] Furthermore, the position warning module 13 of the present embodiment also includes a plurality of light-guiding edge strips 132 arranged around the display screen 12, which are respectively assembled in each of the guide grooves 112 of the front shell 11 and cover the other side of each of the guide grooves 112 relative to the plurality of light-emitting units 131, so as to receive the light of each of the guide grooves 112 and guide it into a warning light that can emit light in a range or region around the side of the display screen 12, thereby forming a warning light that will not directly shine into the driver's eyes, making it easier for the driver to judge the position of approaching objects with his peripheral vision.

[0033] Furthermore, the rear shell 18 is provided with a reflective portion 181 on the inner side corresponding to the position of the plurality of light-emitting units 131. In this embodiment, the reflective portion 181 is roughly annular in shape in conjunction with the arrangement of the plurality of light-emitting units 131, so that the warning lights of the plurality of light-emitting units 131 can be concentrated and emitted toward the front, making the warning light during the early warning brighter and more obvious.

[0034] In addition, the main body 10 of this embodiment is also provided with a TP glass on the front side to protect the display screen 12; the main body 10 is also provided with a speaker 15, a memory card assembly 16, a wire buckle 17 and other components; the speaker 15 and the memory card assembly 16 are electrically connected to the rear side of the circuit substrate 14 and are located between the circuit substrate 14 and the rear shell 18. The speaker 15 is used to emit a warning sound through a plurality of sound source holes 182 opened at the relative position of the rear shell 18 during an early warning (the position warning module 13 emits a warning light), and the memory card assembly 16 can cooperate with a memory card fixing cover 161 provided at the corresponding position of the rear shell to form a slot for attaching a memory card; the wire buckle 17 is used to fix the electrical harness 171 of the circuit substrate 14. In addition, a bracket connection hole 183 can be provided at the central position of the rear shell 18 for the bracket assembly 20 to be assembled.

[0035] In a feasible embodiment, the position warning module 13 is configured with an appropriate number of light-guiding side strips 132 in appropriate positions according to the requirements of the vehicle model, and is surrounded by an appropriate number of light-emitting units 131; and in this embodiment, the position warning module 13 is provided with a light-guiding side strip 132 above, below, on the left and on the right of the display screen 12, respectively, to serve as an early warning for the front, rear, left and right sides of the vehicle body 60 (a warning light is emitted when an object approaches the corresponding side). Further, the light-guiding side strip 132 located above or below the display screen 12 and the corresponding guide groove 112 are arc-shaped.

[0036] In practical application, this embodiment can be used in conjunction with Figures 4 to 8 When an object approaches the vehicle body 60, the driving assistance system 3 can identify the object through the object recognition module 32, predict its future movement trajectory D using the past movement path C through the trajectory prediction module 33, and track and determine whether a warning is required for the distance of the object or its movement trajectory D through the warning judgment module 34. When it is determined that a warning is required, the driving assistance system 3 can drive the vehicle display device 1 to perform relevant actions, that is, display the image or information of the approaching object on the display screen 12, and emit a warning light at the corresponding position of the or the plurality of light-emitting units 131 around the display screen 12 according to the position of the approaching object relative to the vehicle body 60, so that the light-guiding edge strip 132 at the corresponding position lights up to form an obvious warning light block.

[0037] like Figure 4 and Figure 5 As shown, when the warning judgment module 34 determines that the distance of the pedestrian or the moving track D in front of the vehicle body 60 is less than the warning distance, it can instruct the vehicle display device 1 to perform relevant warning actions together with the display control module 35. At this time, the image or data of the object can be displayed on the display screen 12 (in this example, the electronic image A of the pedestrian walking is displayed on the display screen 12, so that the driver can know the type of the object with the peripheral vision), and the plurality of light-emitting units 131 above the display screen 12 emit warning lights, and the light-guiding edge strip 132 located above the display screen 12 (such as Figure 4 As shown), a clearly illuminated warning light block is formed, so that the driver can easily judge with peripheral vision that there is an object approaching the front side of the vehicle body 60, thereby providing a direction warning effect.

[0038] Another example Figure 6 and Figure 7As shown, when the warning judgment module 34 determines that the distance of the pedestrian or its moving trajectory D on the right side of the vehicle body 60 is less than the warning distance, it can instruct the vehicle display device 1 to perform relevant warning actions together with the display control module 35; this example can also display the image or data of the object through the display screen 12 (in this example, the electronic image A of the pedestrian walking is displayed on the display screen 12, so that the driver can know the type of the object with his peripheral vision), and the direction warning part is that the several light-emitting units 131 on the right side of the display screen 12 emit warning lights, and light up the light-guiding edge strip 132 on the right side of the display screen 12 (such as Figure 6 As shown), a clearly illuminated warning light block is formed, so that the driver can easily judge with peripheral vision that there is an object approaching the right side of the vehicle body 60, thereby providing a direction warning effect.

[0039] In other feasible embodiments, the display screen 12 can also be used to display more images. For example, when there is no warning, the display control module 35 can control the display screen 12 to display a bird's-eye view of the vehicle's surrounding image, and when there is a warning, switch to display the image or information of the object in conjunction with the warning light, such as an image cut out from the real-life image, such as a real-life image containing the object at the corresponding position, or a real-life image of the object partially enlarged at the corresponding position, etc., or other electronic image (icon) information that can represent the object, such as Figure 4 or Figure 6 The electronic image A of a pedestrian walking as shown, or Figure 8 There is an electronic image B of an oncoming vehicle on the left side as shown, so that the driver can cooperate with the obvious warning lights around the display screen 12 to easily and quickly determine the direction and type of approaching objects using peripheral vision, allowing the driver to better respond to warning conditions and reduce the occurrence of accidents.

[0040] In summary, the vehicle display device with a position warning function provided by the utility model can form an effect that allows the driver to easily identify the warning position with peripheral vision through the obvious bright warning lights around the display screen 12, which can indeed reduce the burden of the driver's switching of vision, thereby reducing the occurrence of accidents; however, the content of the above description is only a description of the preferred embodiment of the utility model, and all changes, modifications, changes or equivalent substitutions extended from the technical means and scope of the utility model should fall within the scope of the claims of the utility model.
