[0022] Embodiments of the present application are described in detail below, and examples of the embodiments 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.

[0023] The following describes the vehicle parking message display system and the vehicle proposed in the embodiments of the present application with reference to the accompanying drawings.

[0024] Figure 1 The present invention is a connection diagram of a parking message display system for a vehicle according to an embodiment of the present application.

[0025] like Figure 1 As shown, the parking message display system 100 for a vehicle according to an embodiment of the present application may include: an information generating unit 10 , a projection unit 20 and an optical perspective unit 30 .

[0026] The information generation unit 10 is used to receive preset message information and convert the preset message information into a target display image based on a preset light source. The projection unit 20 is used to project the target display image to a preset position of the target glass of the vehicle. The optical perspective unit 30 is used to adjust the projection angle of the target display image based on the parameter data of the vehicle and the parameter data of the target glass, so as to adjust the refraction angle of the target display image in the target glass, so that the target display image is refracted and displayed outside the vehicle.

[0027] Specifically, the information generation unit 10 is used to generate information displayed in an optical form, such as parking message information or other text information. Among them, the preset message information can be pre-set in the vehicle memory, and the user sends the stored preset message information to the information generation unit 10 through the vehicle main control based on actual needs, or the user sends the self-edited message information to the information generation unit 10 through the mobile phone terminal. After receiving the preset message information, the information generation unit 10 performs data conversion on the preset message information, firstly generates information based on the use of light sources such as LED or laser, and converts it into an optical image, i.e., a target display image, through display control technology. It can be understood that the target display image is not limited to text display, but can also be picture information, dynamic information, etc., without specific limitation.

[0028] The projection unit 20 can project the generated target display image using devices such as optical lenses or reflectors. The target glass and the preset position of the target glass can be set based on actual conditions. For example, if the target glass is the front windshield of the vehicle, the preset position is the lower left corner of the front windshield to display the target display image to the person in front of the vehicle; if the target glass is the rear windshield of the vehicle, the preset position is the middle and lower position of the rear windshield to display the target display image to the person behind the vehicle. It is understandable that based on the different preset positions of the target glass, each unit in the parking message display system 100 can also be independently set based on actual conditions to improve the display applicability.

[0029] The optical perspective unit 30 can adjust the refraction angle and projection angle of light according to the parameter data of different vehicles and the parameter data of the target glass to ensure that the projected image can be clearly seen by people outside the vehicle. In one embodiment of the present application, the parameter data of the vehicle includes the model data of the vehicle, and the parameter data of the target glass includes the shape data of the target glass. For example, the vehicle height, vehicle structure, glass material and other information can be determined according to the model data of the vehicle to ensure that the projection height and direction of the image are compatible with the vehicle height, and to avoid the occlusion of the projection caused by the vehicle structure. In addition, the refractive ability of the glass can be determined according to the glass material information for subsequent adjustment of the specific projection angle; the boundary position of the target glass and the curvature of the target glass can be determined according to the shape data of the target glass to determine the specific coordinates of the preset position and the target refraction angle, so as to adjust the projection angle so that the projected image can be clearly seen by people outside the vehicle.

[0030] The parking display system can conveniently and autonomously edit and display parking message information, and use the refraction of light to display the target display image to people outside the vehicle. At the same time, the display position and display effect of the target display image can be adjusted based on the adjustment of the projection position and the refraction angle, which can provide better communication and information sharing, enhance the interactivity between the vehicle and the surrounding environment, and greatly improve the flexibility and convenience of parking messages. In addition, the flexible setting of message information solves the drawbacks of the related technology that the content of the parking message board cannot be flexibly edited and can only record the owner's phone number. While ensuring the interactive effect of the message, it avoids the continuous leakage of privacy information and improves the safety and convenience of use.

[0031] In one embodiment of the present application, the vehicle parking message display system 100 also includes: a control unit 40, which is connected to the vehicle's input unit and is used to receive first preset information provided by the vehicle's input unit to generate preset message information based on the first preset information.

[0032] Specifically, the input unit of the vehicle may be a trigger button, a vehicle control display screen, etc., for sending the first preset information to the control unit 40. The control unit 40 is used to generate preset message information based on the received first preset information, and send it to the information generation unit 10. The control unit 40 may adopt an electronic control system, and then realize the generation and projection of information through the driver's control, and may be set and adjusted as needed.

[0033] For example, the control unit 40 may store multiple message content templates in advance, and each trigger button corresponds to a different message content template. When the driver presses the trigger button, the control unit 40 uses the message content template corresponding to the trigger button as the preset message information and sends it to the information generation unit 10. The driver can also edit the first preset information on the vehicle control display screen and then send it to the control unit 40. The control unit 40 performs data conversion on the first preset information and outputs the preset message information.

[0034] In one embodiment of the present application, the vehicle parking message display system 100 also includes: a networking unit 50, which is used to receive second preset information sent by an external terminal and convert the second preset information to the control unit 40; the control unit 40 is also used to generate preset message information based on the second preset information.

[0035] Specifically, the networking unit 50 receives the second preset information sent by the external terminal based on network remote transmission, and forwards the second preset information to the control unit 40, thereby realizing the remote control of the parking message information content by the external terminal.

[0036] In addition, the external terminal can also send a start-stop control instruction to the control unit 40 through the networking unit 40, so that the control unit 40 controls the information generation unit 10, the projection unit 20 and the optical perspective unit 30 to work according to the start control instruction, and controls the information generation unit 10, the projection unit 20 and the optical perspective unit 30 to stop working according to the stop control instruction.

[0037] In one embodiment of the present application, the vehicle parking message display system 100 further includes: a positioning unit 60 for acquiring the location information of the vehicle so that the control unit 40 controls the information generation unit 10, the projection unit 20 and the optical perspective unit 30 based on the location information of the vehicle.

[0038] Specifically, the positioning unit 60 is used to locate the vehicle position, and the control unit 40 determines whether to trigger the parking message display function according to the vehicle position information. For example, the control unit 40 determines whether to display the parking message information according to the position information. For example, if the vehicle is parked in its own parking space, the parking message information is not displayed by default; but if the vehicle is parked temporarily on the roadside, the parking message information is displayed by default. This default value can be set by the vehicle owner.

[0039] In one embodiment of the present application, the control unit 40 is also used to control the information generation unit 10, the projection unit 20 and the optical perspective unit 30 to be in a working state when it is determined based on the vehicle's position information that the vehicle is in a target parking state, and to control the information generation unit 10, the projection unit 20 and the optical perspective unit 30 to be in a stopped working state when it is determined based on the vehicle's position information that the vehicle is not in the target parking state.

[0040] In one embodiment of the present application, the target parking state is a parking state in which the vehicle is not in its own bound parking space.

[0041] That is to say, the controller 40 can store the vehicle-bound parking spaces in advance. When it is determined that the parking position of the vehicle is consistent with the pre-stored bound parking space, it is considered that there is no situation of moving the vehicle and emergency contact, and the control information generation unit 10, the projection unit 20 and the optical perspective unit 30 are controlled to stop working to reduce energy consumption; when it is determined that the parking position of the vehicle is inconsistent with the pre-stored bound parking space, the control information generation unit 10, the projection unit 20 and the optical perspective unit 30 are controlled to work to display the message information, which is not limited to the contact information.

[0042] Therefore, this embodiment turns the parking message function on or off based on the vehicle's location information. While ensuring the effect of the parking message, it can also reduce the risk of leakage of the owner's private information, reduce energy consumption, and improve the flexibility of the parking message.

[0043] In one embodiment of the present application, the parking message display system 100 for a vehicle further includes: a sensing unit 70 for sensing the parking situation of a person within a target range. The control unit 40 is further configured to control the information generation unit 10, the projection unit 20, and the optical perspective unit 30 to be in a working state when the vehicle is in a target parking state and a person is parked within the target range, and to control the information generation unit 10, the projection unit 20, and the optical perspective unit 30 to be in a stopped working state when the vehicle is not in a target parking state, or when the vehicle is in a target parking state and no person is parked within the target range.

[0044] Specifically, the sensing unit 70 can be implemented by a camera, and the target range can be limited by taking the vehicle as the center and the preset distance as the radius. When the vehicle is in a parking state, when the sensing unit 70 senses that a person enters the target range, or when the person stays in the target range for 20 seconds, the control information generation unit 10, the projection unit 20 and the optical perspective unit 30 start working to display the parking message information, otherwise, the control information generation unit 10, the projection unit 20 and the optical perspective unit 30 stop working.

[0045] This embodiment controls the start and stop of the parking message function in combination with the parking status of the vehicle and the parking situation of the personnel, thereby further reducing energy consumption while ensuring that the parking message information is conveyed to the personnel outside the vehicle in a timely manner.

[0046] In one embodiment of the present application, the parking message display system 100 of the vehicle further includes: a display screen 80 arranged corresponding to the target glass, the display screen 80 being arranged inside the vehicle and being used to intercept and display the target display image reflected by the target glass.

[0047] Specifically, taking the target glass as the windshield as an example, a display screen 80 can be added to the windshield to intercept the projected image on the display screen 80. The advantage of this is that the target display image of the parking message can be observed even if you are not directly in front of the windshield.

[0048] As a specific embodiment of the present application, Figure 2 As shown, the parking message display system 100 of the vehicle receives preset information triggered by the user through the control unit 40, generates preset message information based on the preset information, and sends it to the information generation unit 10. The information generation unit 10 converts the preset message information into a target display image, and then uses the refraction of light through the projection unit 20 and the optical perspective unit 30 to display the target display image to people outside the vehicle for viewing, thereby realizing the parking message function, providing better communication and information sharing, and enhancing the interactivity between the vehicle and the surrounding environment.

[0049] In addition, users can edit and display parking message information independently through the vehicle control platform or terminal devices such as mobile phones, including but not limited to text, images, emoticons, etc., which solves the problem that the content of the parking message board cannot be flexibly edited and can only record the owner's phone number. At the same time, the control unit 40 can also control the start or stop of the parking message function based on the external terminal to achieve remote control of the parking message. And the control unit 40 can also control whether to display the parking message information and the message content in combination with the parking position of the vehicle, which greatly improves the convenience and privacy protection of the owner. In addition, for vehicles with head-up display, the information generation unit 10, projection unit 20, and optical perspective unit 30 of the parking display system 100 can also share modules with the head-up display system, reducing hardware costs.

[0050] In summary, according to the parking message display system of the vehicle in the embodiment of the present application, the preset message information is received through the information generation unit, and the preset message information is converted to generate a target display image based on the preset light source, and the target display image is projected to the preset position of the target glass of the vehicle through the projection unit, and the optical perspective unit adjusts the projection angle of the target display image based on the parameter data of the vehicle and the parameter data of the target glass to adjust the refraction angle of the target display image in the target glass so that the target display image is refracted and displayed outside the vehicle. Therefore, the system can change the parking message information based on the preset message information, and can also adjust the display position and display effect of the target display image based on the adjustment of the projection position and the refraction angle, which greatly improves the flexibility and convenience of parking messages.

[0051] Corresponding to the above embodiments, the present application also proposes a vehicle.
