Description

Technical Field

[0001] This utility model belongs to the field of intelligent vehicles. Specifically, this utility model relates to a vehicle height limit warning system and a vehicle. Background Technology

[0002] Vehicle height restriction recognition is of great significance for safe driving and traffic management. Current technologies often use radar and other equipment to collect height restriction information.

[0003] For example, the patent document with publication number CN222545507U, publication date 2025-02-28, and patent title "A LiDAR-based Height Limit Detection and Warning Unit for Refrigerated Trucks" discloses a LiDAR-based height limit detection and warning unit for refrigerated trucks, including: a housing, a LiDAR sensor, a processor, and a warning device. The LiDAR sensor is used to measure the distance between the refrigerated truck and the height limit bar. The LiDAR sensor, processor, and warning device are electrically connected in sequence. The LiDAR sensor, processor, and warning device are all located in the housing, and the housing is installed on the front exterior of the refrigerated truck compartment.

[0004] The previously published document used radar sensors to measure the distance between a refrigerated truck and a height restriction barrier. However, with increasingly complex road conditions, radar and similar equipment are gradually failing to meet the accuracy requirements for height restriction identification and are easily affected by environmental interference. Therefore, this application proposes a vehicle height restriction warning system and a vehicle. Utility Model Content

[0005] This utility model aims to overcome the shortcomings of the existing technology and proposes a vehicle height restriction warning system and vehicle to achieve the following objectives: by integrating technologies such as deep learning video recognition and cloud collaboration, it can achieve accurate identification and intelligent warning of over-height vehicles.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vehicle height restriction warning system, the system including a forward road height restriction recognition device, an in-vehicle edge computing unit, a cloud server, multiple in-vehicle control interfaces, and an in-vehicle central control screen, wherein the in-vehicle edge computing unit is connected to the forward road height restriction recognition device, the cloud server, and the in-vehicle control interfaces respectively; the in-vehicle control interfaces are connected to the in-vehicle central control screen.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the terms "first," "second," etc., used in this application are only for the convenience of describing the technical solution and distinguishing different components, and are not intended to limit this application. To make the technical solution of this utility model clearer, it will be explained and illustrated through the following embodiments.

[0020] This embodiment provides a vehicle height restriction warning system, such as Figure 1As shown, the system includes a forward road height restriction recognition device, an in-vehicle edge computing unit, a cloud server, multiple in-vehicle control interfaces, and an in-vehicle central control screen. The in-vehicle edge computing unit is connected to the forward road height restriction recognition device, the cloud server, and the in-vehicle control interfaces, respectively. The in-vehicle control interfaces are connected to the in-vehicle central control screen.

[0021] Specifically, the forward road height restriction recognition device in this embodiment includes a vehicle-mounted high-definition wide-angle camera, which is connected to the vehicle-mounted edge computing unit. The vehicle-mounted high-definition wide-angle camera is used to capture images of the road ahead and send them to the vehicle-mounted edge computing unit. The high-definition wide-angle design ensures the clarity of the image coverage area of ​​the road ahead. Furthermore, this embodiment also mounts the camera on the top of the vehicle body to prevent the camera from being blocked by the vehicle in front and failing to recognize forward height restriction obstacles while the vehicle is moving.

[0022] The vehicle-mounted edge computing unit integrates a deep learning image processing model (such as YOLO, an existing technology where the edge computing unit merely serves as the physical carrier for algorithm execution). It receives images of the road ahead captured by a high-definition wide-angle camera and identifies the height limit of the road ahead using the deep learning image processing model. This vehicle-mounted edge computing unit, with its integrated deep learning image processing model, achieves height limit recognition accuracy far exceeding traditional lidar or infrared systems, and is less affected by weather (fog, rain, snow) and lighting changes, enabling reliable all-weather operation. After obtaining the height limit, the vehicle-mounted edge computing unit compares it with a preset vehicle height. If the height limit exceeds the preset limit, the edge computing unit sends a warning signal to the vehicle control interface. The vehicle control interface then forwards this warning signal.

[0023] In this embodiment, the vehicle control interface is connected to the vehicle's central control screen. The vehicle control interface forwards the warning signal issued by the vehicle edge computing unit to the vehicle's central control screen. This example uses either a CAN communication interface or an OBD communication interface, which are universal interfaces for vehicles, saving secondary development costs. The vehicle's central control screen receives the warning signal and alerts the user through a visual interface and a built-in voice assistant. Simultaneously, the vehicle's central control screen uses a human-machine interface, displaying the warning while also supporting user command input, which is forwarded to the vehicle edge computing unit via the vehicle control interface. The user command input includes preset parameters such as vehicle height.

[0024] Meanwhile, the vehicle-mounted edge computing unit is also connected to the cloud server via a wireless communication network, so that the vehicle-mounted edge computing unit can automatically upload the height limit recognition results, received images, navigation and other data to the cloud server for remote monitoring and data analysis.

[0025] In a preferred embodiment of this invention, the forward road height restriction recognition device further includes a navigation system connected to the vehicle-mounted edge computing unit. The navigation system acquires the forward road height restriction information in real time and pushes it to the vehicle-mounted edge computing unit. Based on the height restriction information from the navigation system, on the one hand, when the vehicle-mounted high-definition wide-angle camera is working normally, the vehicle-mounted edge computing unit can perform redundant verification on the height restriction information it identifies to improve the accuracy of height restriction recognition; on the other hand, when the vehicle-mounted high-definition wide-angle camera malfunctions, it can serve as a replacement to ensure the normal operation of the system.

[0026] In a preferred embodiment of this invention, the system further includes a vehicle height adjustment device, which is connected to the vehicle edge computing unit via a vehicle control interface. For example, a vehicle equipped with a vehicle height adjustment device (e.g., a lift cargo box) has an adjustable height. The vehicle height adjustment device can receive warning signals from the vehicle edge computing unit via the vehicle control interface and adjust the vehicle height accordingly to ensure the vehicle safely passes through the road ahead.

[0027] In a preferred embodiment of this invention, the system further includes a head-up display (HUD), which is connected to the vehicle-mounted edge computing unit via an in-vehicle control interface. The in-vehicle control interface forwards the warning signals emitted by the vehicle-mounted edge computing unit to the HUD, which then processes the warning signals and displays them on the HUD interface to alert the user. In another preferred embodiment of this invention, the system further includes an instrument panel, which is connected to the vehicle-mounted edge computing unit via an in-vehicle control interface. The in-vehicle control interface forwards the warning signals emitted by the vehicle-mounted edge computing unit to the instrument panel, which then alerts the user via indicator lights or other means. These two preferred embodiments, by providing multiple alarm methods, ensure that users receive timely warnings, thereby avoiding height-restricted road sections and ensuring vehicle driving safety.

[0028] This application also proposes a vehicle that includes the aforementioned vehicle height restriction warning system.

[0029] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
