Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted human-machine interaction technology, and more particularly to a vehicle external interaction display control system and interaction method. Background Technology

[0002] With the continuous development of intelligent vehicles, some vehicles are equipped with rear-end displays to convey vehicle information. Most existing rear-end displays support the free input of any text and images; editing content while driving can easily distract the driver, posing a safety hazard. Furthermore, the lack of unified interaction standards results in cluttered display content, making it difficult for oncoming road users to quickly understand the information. Some models utilize headlight patterns for entertainment-oriented interaction, but this lacks a complete and standardized interaction system and struggles to automatically convey vehicle intentions such as reversing, U-turns, and parking in conjunction with autonomous driving conditions. The interaction methods are simplistic, limiting the effectiveness of road communication. Additionally, traditional fixed material libraries cannot be continuously iterated upon, resulting in insufficient scalability. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vehicle external interactive display control system and interaction method, which solves the problem that existing vehicles rely solely on headlights and horns to transmit signals, resulting in limited expression of driving intentions, easy misjudgment by pedestrians and surrounding vehicles, and potential traffic safety hazards; at the same time, it solves the defect that existing external display devices have complex structures and are difficult to adapt to ordinary mass-produced vehicles. Technical solution

[0004] To achieve the above objectives, this invention provides a vehicle external interactive display control system, comprising an operation unit, a signal transmission module, a rear-end display unit, and a voice recognition module. The operation unit is installed in the vehicle's central control system and internally houses a pre-set interactive element database. The database contains various interactive elements, including Chinese characters, numbers, English letters, text interaction symbols, and standardized graphic icons, each type of interactive element pre-assigned a fixed driving interaction meaning. The operation unit only allows selection of interactive elements from the database and does not support manual input of arbitrary custom content by the driver. The database supports remote updates in the background, with interactive elements added and adjusted uniformly by a cloud server; the vehicle terminal does not grant the driver permission to add custom materials.

[0005] Drivers can select interactive elements via the central control screen or issue commands through the voice recognition module to match corresponding interactive elements. Voice commands can only call interactive elements already stored in the database and do not support custom input. Furthermore, the operating unit can communicate with the autonomous driving control system. When the autonomous driving control system detects that the vehicle is performing reversing, U-turn, or automatic parking actions, it automatically matches the corresponding interactive elements in the database and triggers the display unit at the rear of the vehicle to show them.

[0006] The signal transmission module transmits commands to the rear display unit. The rear display unit is located in the rear-facing visible area of ​​the vehicle and includes at least one of a rear-mounted independent display screen, a taillight display area, and a rear windshield display device. Each rear display unit displays only a single interactive element at a time. The system has a built-in timing mechanism; the interactive element is automatically turned off after a preset display duration. The system supports setting multiple display durations to adapt to different road conditions. Furthermore, the operating unit can automatically filter available interactive elements for the current scenario based on vehicle speed, gear, and other driving conditions, and block inappropriate interactive content. The "no support for freely customizable content input" mentioned in this invention means that the driver cannot generate or input entirely new text or graphic materials outside the database; the driver can only select interactive elements that are pre-stored in the database and pre-bound with vehicle interaction meanings. Even if the interactive elements in the database can be arranged and combined, no entirely new interactive materials outside the database will be generated.

[0007] The present invention also provides a method for interactive display of a vehicle, comprising the following steps: S1, the driver selects preset interactive elements via central control or voice; or the autonomous driving control system automatically matches the target interactive elements; the database can receive background data to complete remote updates; s2, the operation unit generates the corresponding display command and sends it to the rear unit via the signal transmission module; s3, the rear display unit receives the instruction, displays the selected interactive element, and transmits vehicle interaction information to surrounding road users; when the display time reaches the preset threshold, the display is automatically turned off.

[0008] Beneficial effects: 1. A closed-loop, pre-set database of interactive elements is adopted to restrict drivers from customizing their input on-site, standardize the interactive content at the rear of the vehicle, and improve driving safety; 2. The resource library supports remote updates from the backend, and the interactive content can be continuously expanded after the product is launched, making it highly scalable; 3. It features both central touchscreen and voice control, and also supports automatic information output in conjunction with autonomous driving, making it suitable for a wide range of scenarios; 4. The interactive formats include text, symbols, and graphic icons, offering a rich variety of expressive methods; 5. The rear display unit has multiple installation positions to suit various vehicle models; 6. An automatic timer shutdown mechanism is set to avoid road interference caused by prolonged display; 7. Establish a unified standard for vehicle rear-end interaction to facilitate road users in quickly identifying vehicle driving intentions and reducing road conflicts. Attached Figure Description

[0009] Figure 1This is a block diagram of the overall structure of the vehicle external interactive display system of the present invention; In the diagram: 1-Operating unit, 2-Signal transmission module, 3-Rear display unit, 4-Voice recognition module, 5-Automatic driving control system. Detailed Implementation

[0010] The invention will be further described below with reference to the accompanying drawings.

[0011] like Figure 1 As shown, the system includes: 1. Operation unit, 2. Signal transmission module, 3. Rear-end display unit, 4. Voice recognition module, and 5. Autonomous driving control system.

[0012] The central control unit stores standardized preset interactive elements, including Chinese characters, numbers, letters, text symbols, and standardized graphic symbols such as U-turn, reversing, and wheelchair accessibility signs. These standardized graphic symbols include national standard traffic signs, reversing icons, U-turn diagrams, autonomous driving status prompts, and accessibility signs—common vehicle interaction patterns. Each interactive element corresponds to a fixed driving meaning. Drivers can only select preset content from the database and cannot create custom patterns or text on the vehicle's device. Manufacturers can remotely push update packages from the backend to add or modify interactive elements in the database.

[0013] While driving, the driver can touch the central control screen to select interactive elements or activate the voice recognition module to access corresponding content. When the vehicle is in autonomous driving mode, the system recognizes reversing, U-turns, and automatic parking, automatically triggering the corresponding interactive elements. Commands are transmitted to the rear display unit via the signal transmission module.

[0014] The rear display unit can be an external display screen in the trunk, integrated into the taillight assembly, or a rear window display. Once the interactive elements begin displaying, the countdown automatically turns off, supporting short and long duration options. When the vehicle is traveling at high speed, the system automatically disables some unsuitable interactive elements to ensure driving safety.
