[0023] The following is further described in detail through specific implementation methods:

[0024] The symbols in the drawings of the specification include: vehicle 1, display screen 2, driver 3, rearview mirror 4, rearview mirror reflector 5, and vehicle door 6.

[0025] Example

[0026] This embodiment is basically Figure 1 , Figure 2 As shown: A vehicle 1 is equipped with an on-board display system, which includes a control module, a sensing module and a display module:

[0027] The perception module includes a UWB component for detecting the distance between the user and the vehicle 1 and the user's position relative to the vehicle 1. In this embodiment, the UWB component is integrated with the vehicle 1 key, and in another embodiment, the UWB component is integrated with the mobile phone. UWB is an accurate and real-time ranging and positioning technology, with ranging and positioning accuracy to the centimeter level, and a secure timestamp is added to UWB, so that the perception module has the ability to prevent relay attacks, greatly improving the security of the vehicle 1 key.

[0028] In this embodiment, the AVM component is a 360° surround view system, which collects images of the environment around the vehicle 1 (around the vehicle 1 and under the chassis) through multiple cameras around the vehicle 1, on the top of the vehicle 1 and on the bottom of the vehicle 1, and stitches the images into a panoramic image through an image stitching algorithm. The panoramic image is output to the display module via the on-board computer.

[0029] The display module in this embodiment is a display screen 2, and is a transparent LED screen. Taking the left-hand drive vehicle 1 as an example, the LED screen is integrated on the front and rear windows of the cab side of the vehicle 1, namely, the left front door window glass and the left rear door window glass. In other embodiments, the display module can also be installed on the front windshield, the rear windshield, the right front door window glass and the right rear door window glass.

[0030] The control module, which is a vehicle-mounted computer in this embodiment, is used to obtain data from the UWB component and the AVM component, and output the image data to be displayed to the LED screen on the side window glass of the cab.

[0031] Driver 3 approaches vehicle 1 from the rear to the front of the vehicle 20 meters away from the left side of vehicle 1. When the UWB component detects that driver 3 is within 10 to 20 meters of vehicle 1, the positioning and ranging functions of the UWB component are turned on. When driver 3 enters the range of 3 to 10 meters, the panoramic image is first displayed on the side window glass of the left rear door. When driver 3 enters the range of 1 to 3 meters, the panoramic image moves from the side window glass of the left rear door to the side window glass of the cab according to the walking speed of driver 3, until driver 3 enters the range of 1 meter, and the panoramic image moves to the side window glass of the cab. Before entering vehicle 1, driver 3 can check the environment around vehicle 1 through the image displayed on the window glass.

[0032] In another embodiment, the display screen 2 is an opaque OLED screen, which is mounted on the exterior rearview mirrors 4 on both sides of the vehicle. Figure 4As shown, after the OLED screen is installed in the frame of the exterior rearview mirror 4, a rearview mirror reflective sheet 5 is covered. The rearview mirror reflective sheet 5 is made of a transparent substrate, and then a reflective film is plated on the light-emitting sheet of the rearview mirror 4 by using a vacuum electroplating process. When the OLED screen is off, the light-emitting lens of the rearview mirror 4 can be used as a normal reflector. The OLED screen is dark and difficult to be seen by the naked eye, which has an "invisible" effect; when the OLED screen is on, the light of the image displayed by the OLED screen can penetrate the light-emitting lens of the rearview mirror 4 and be seen by the driver 3. When the area of ​​the interior rearview mirror 4 is sufficient to display the image clearly and the perspective effect of the side window glass is good, the display module can also be installed on the interior rearview mirror 4.

[0033] In another embodiment, the image displayed in the display module is a cropped panoramic image: the driver 3 gets on the vehicle from the left side, and can visually check the environment on the left side of the vehicle 1 during the getting on process, so the left part of the panoramic image is cropped, and the remaining image area becomes smaller. The remaining image can be enlarged when displayed, which is more convenient for the driver 3 to view.

[0034] In another embodiment, as shown in the attached Figure 3 As shown, the control module also includes an image recognition component, which includes a GPU chip and a memory loaded with an image recognition AI computer program, which is used to identify objects in the AVM-generated image and mark them on the image: for example, marking cats, dogs, children, steps, etc.

[0035] In another embodiment, as shown in the attached Figure 3 As shown, the control module is connected to the wireless communication component, which is a 5G communication module. The wireless communication component communicates with the information terminal outside the vehicle (the 5G mobile phone of the driver 3), and obtains information such as weather information, stock information of interest, schedule information, temperature and humidity, air quality, etc. according to the driver 3's preference settings, and displays it on the vehicle body, window glass or rearview mirror 4 through the display module.

[0036] In another embodiment, an information interaction system is also included. In this embodiment, the information interaction system includes a voice interaction system and a gesture visual recognition system. The voice interaction system mainly includes a microphone, and the gesture visual recognition system mainly includes a gesture recognition camera. The microphone and the gesture recognition camera are respectively installed in groups on the window frames above the side window glass. The interaction with the driver 3 is achieved by recognizing the voice and gestures of the driver 3.

[0037] In yet another embodiment, the display screen 2 is an opaque OLED screen, which is mounted on the vehicle body. Figure 5As shown, more specifically, it is installed on the outer surface of the door 6 of the cab. In this specification, the body refers to the outer surface portion of the vehicle 1 covered by the shell and its decorative parts, including but not limited to the door 6, the roof, the hood, the front and rear bumpers, the trunk lid and other parts. The display module in this embodiment can also be invisible as in the above embodiment.
