Description

I ntra-Vehicular Data Transmission and Display SystemField of the Invention

[0001] The field of the specification relates to systems and methods for intra-vehicular communication, specifically to systems that facilitate the transmission and display of data between vehicles in proximity, allowing for the exchange of profile information and other relevant data. This field encompasses vehicle-to-vehicle communication technologies, user interface design for automotive applications, and data processing techniques for enhancing driver interaction and safety.Background of the Invention

[0002] In modern vehicular environments, there is a growing demand for improved communication and data sharing between vehicles to enhance safety, convenience, and user experience. Traditional vehicle systems are primarily focused on internal functionalities, such as navigation, entertainment, and diagnostics. However, as vehicles become increasingly connected, the need for systems that enable interaction between vehicles on the road has emerged. These interactions can provide drivers with valuable information about other vehicles in their vicinity, contributing to more informed driving decisions and potentially reducing the risk of accidents.

[0003] Existing technologies for vehicle-to-vehicle communication often rely on complex and costly infrastructure, such as dedicated short-range communication (DSRC) systems or advanced telematics. While these systems offer significant benefits, their adoption has been limited due to the need for specialised equipment and infrastructure. Additionally, many current solutions are designed for specific use cases, such as emergency vehicle prioritisation or collision avoidance, rather than for broader applications like social interaction or data sharing between ordinary vehicles.

[0004] As the automotive industry continues to evolve, there is a pressing need for more versatile and accessible systems that can facilitate a wide range of vehicle-to- vehicle interactions. These systems should ideally integrate with existing vehicle components and technologies, minimising the need for additional hardware while offering a seamless user experience. The technical challenge lies in developing asystem that can operate effectively across different vehicle models and environments, providing reliable communication and data exchange without requiring extensive modifications to the vehicle’s existing infrastructure.Summary of the Disclosure

[0005] The present patent specification describes an intra-vehicular data transmission and display system designed to facilitate the exchange and display of profile information between vehicles when they are in proximity. The system includes a vehicle receiver subsystem equipped with a digital display and controllers that manage the user interface and data presentation. The system is capable of detecting the proximity of another vehicle, retrieving relevant profile data from a database, and displaying this data on the digital display.

[0006] Various embodiments are disclosed, including the use of GPS-based proximity detection, direct communication between vehicles, and the integration of an image sensor for licence plate recognition. The system may also incorporate a transponder within the vehicle's licence plate, allowing seamless data transmission without additional system configuration. Additional features include options for user- controlled data sharing, selective display of profile data fields, and two-way communication between vehicles. The method of operation for the system is detailed, outlining the steps involved in proximity monitoring, data retrieval, and display, as well as the potential for enabling two-way data exchange. The system is designed to enhance driver interaction, safety, and convenience on the road.

[0007] According to one aspect, there is provided an intra-vehicular data transmission and display system comprising a vehicle receiver subsystem including a digital display and one or more controllers configured to manage a user interface on the display, the system being operable to detect proximity to another vehicle, determine a profile associated with that vehicle, retrieve profile data from a database, and present the data on the display.

[0008] In some embodiments, proximity is determined by both the vehicle receiver subsystem and the other vehicle reporting their locations to a server, which compares the reports to identify when they are within a defined range. This approach leveragesexisting GPS infrastructure, thereby reducing hardware overhead and allowing crosscompatibility across vehicle types.

[0009] Alternatively, the receiver subsystem may directly read the profile from the other vehicle when in close range. Suitable short-range communication technologies include Wi-Fi Direct, Bluetooth, or NFC, enabling effective operation even in areas with limited or no cellular coverage.

[0010] In another form, the receiver subsystem may incorporate an image sensor to capture an image of a licence plate, apply optical character recognition to extract alphanumeric identifiers, and identify the associated profile on that basis. This provides redundancy in cases where network or transponder-based communication is unavailable.

[0011] It is also envisaged that a vehicle may be equipped with a transponder arranged to transmit its profile to the receiver subsystem when in range. The transponder may be configured to transmit automatically or, in preferred cases, only in response to a request signal from the receiver subsystem. By limiting transmission to explicit requests, user privacy is preserved and unnecessary broadcasting is avoided.

[0012] The transmitting vehicle may further comprise a computer subsystem with its own display and controllers, arranged to present a request for authorisation and accept input from the driver approving or denying transmission of profile data. This permits fine control over the type and extent of information shared. Preferably, the profile data is structured into fields, with drivers able to select which fields are disclosed. The subsystem may also record the identity of previously approved receiver subsystems, enabling subsequent approvals to occur without repeated authorisation, thereby improving convenience.

[0013] In some implementations, the request issued by the receiver subsystem can include parameters such as vehicle class or driver profile, and the transponder may be configured to evaluate these parameters against stored criteria before releasing profile data. Such conditional transmission ensures that information is exchanged only with suitable or trusted vehicles.

[0014] Optionally, the system supports two-way data exchange. This may include a text-based chat capability, allowing drivers to exchange messages directly between their displays. Such functionality enables richer interactions, particularly for social groups, clubs, or coordinated travel.

[0015] The profile data itself may comprise text, such as the driver’s name, vehicle model or affiliation, and may also include images, such as photographs or logos. Providing both textual and graphical information allows for flexible and informative presentation tailored to user preferences.

[0016] In a further development, the vehicle licence plate may incorporate the transponder as an integrated unit. This arrangement simplifies installation, optimises antenna positioning for reliable communication, and improves resistance to tampering or environmental degradation. The integrated transponder may be configured to broadcast automatically, or only in response to explicit requests, while benefiting from the inherent durability and standardised mounting of a licence plate.

[0017] A further aspect relates to a method of operating such a system, including the steps of monitoring proximity between a receiver subsystem and another vehicle, sending a request to a server for profile data associated with that vehicle, evaluating the retrieved data to determine which fields are to be displayed, and presenting the data on a display. The method may additionally include enabling two-way data exchange, thereby extending the interaction beyond passive information display.

[0018] Other aspects of the invention are also disclosed.Brief Description of the Drawings

[0019] Notwithstanding any other forms which may fall within the scope of the present invention, preferred embodiments of the disclosure will now be described, by way of example only, with reference to the accompanying drawings in which:

[0020] Figure 1 shows a block level diagram of the intra-vehicular data transmission and display system (100); and

[0021] Figure 2 shows a flowchart illustrating the method (200) of operating the intra- vehicular data transmission and display system.Description of Embodiments

[0022] Figure 1 shows an intra-vehicular data transmission and display system (100) designed to facilitate the exchange and display of profile information between vehicles when they are in proximity. This system (100) enables various modes of communication and data sharing between vehicles (104), potentially enhancing social interactions, safety, and the user experience on the road. The system (100) is primarily composed of a vehicle receiver subsystem (101), which includes a digital display (102) and one or more controllers (103). The receiver subsystem (101) may comprise a processor for processing digital data and a memory device in operable communication with the processor via a system bus. The memory device is configured for storing computer program code instructions and associated data which are fetched, decoded and executed by the processor in use. These computer program code instructions may be logically divided into the controllers (103) assigned respective computational tasks as described herein. The digital display (102) is used to present a user interface, which is managed by the controllers (103) to display relevant profile data retrieved based on the proximity of the vehicle receiver subsystem (101) to another vehicle (104).

[0023] In one broad aspect of the invention, the system (100) is configured to detect the proximity of the vehicle receiver subsystem (101) to another vehicle (104). This detection can be achieved using various methods, including, but not limited to, GPSbased location tracking. For example, the vehicle receiver subsystem (101) could be integrated with the vehicle’s (104) onboard GPS unit, which continuously reports the vehicle's (104) location to a server (106). The server (106) compares the reported location with that of other vehicles (104) within a predefined area. When two vehicles (104) are detected within a certain range, the server (106) initiates the retrieval of the profile data associated with the detected vehicle (104). This configuration is advantageous as it utilises existing GPS infrastructure, reducing the need for additional hardware installations. The system (100) can be implemented as an application running on a mobile device integrated with the vehicle receiver subsystem(101), allowing for a cost-effective and widely compatible solution across different vehicle models.

[0024] In another preferred embodiment, the vehicle receiver subsystem (101) is configured to read the profile directly from the vehicle (104) when in proximity. This could be achieved through direct communication technologies such as Wi-Fi direct Bluetooth or NFC, where the vehicle receiver subsystem (101) establishes a short- range communication link with the vehicle (104). This method is particularly beneficial in scenarios where network connectivity may be limited, such as in rural areas. The vehicle receiver subsystem (101) could initiate a connection with the vehicle (104) as it comes within a predefined range, automatically retrieving and displaying the profile data on the digital display (102). This embodiment ensures that the system (100) functions effectively even in areas with poor cellular network coverage.

[0025] It should be noted that whereas Wi-Fi direct may be used for direct communication between the vehicle receiver subsystem (101) and the vehicle (104) , in embodiments, the vehicle receiver subsystem (101) and the vehicle (104) may communicate via installed gateways, such as Wi-Fi routers installed at traffic lights or other infrastructure.

[0026] In further embodiments, the vehicle receiver subsystem (101) and the vehicle (104) may communicate via satellite transponders.

[0027] To enhance the system's (100) functionality, the vehicle receiver subsystem (101) may include an image sensor (107) configured to capture an image of the vehicle’s (104) licence plate. The image sensor (107) can be integrated into the vehicle receiver subsystem (101) and used in conjunction with optical character recognition (OCR) technology to identify the vehicle (104) based on the licence plate. Once the licence plate is recognised, the system (100) can cross-reference the alphanumeric characters with a database (105) to retrieve the associated profile. This embodiment is particularly useful in environments where a vehicle’s (104) transponder (108) may not be functioning correctly or in situations where a visual confirmation of the vehicle’s (104) identity is required.

[0028] In some implementations, the vehicle (104) itself may be equipped with a transponder (108) configured to transmit the profile to the vehicle receiver subsystem(101) when in proximity. The transponder (108) could operate on various radio frequencies, much like how NFC tags respond to specific radio frequency signals. This method allows for a seamless and automatic transfer of data between the vehicle (104) and the vehicle receiver subsystem (101). For instance, as the vehicle receiver subsystem (101) comes within range of the vehicle (104), the transponder (108) automatically transmits the profile data, which is then displayed on the digital display(102). This feature is advantageous in situations where minimal user interaction is desired, providing a hands-free experience for the driver.

[0029] In certain configurations, the transponder (108) is designed to transmit the profile data only in response to a request from the vehicle receiver subsystem (101). This approach adds a layer of control, ensuring that profile data is not transmitted unless explicitly requested by the vehicle receiver subsystem (101). For example, the controllers (103) within the vehicle receiver subsystem (101) could generate a request signal upon detecting proximity to another vehicle (104), prompting the transponder (108) to transmit the relevant profile data. This conditional transmission helps to protect user privacy and allows for selective sharing of information.

[0030] Furthermore, the vehicle (104) may include a computer subsystem (109) that comprises a digital display (110) and one or more controllers (111) configured to display a user interface on the digital display (110). The user interface could be designed to display the request for profile data received from the vehicle receiver subsystem (101) and to allow the user to authorise or deny the transmission of their profile data. This real-time authorisation feature provides users with control over what information is shared and under what circumstances. For example, a prompt could appear on the digital display (110) within the vehicle (104), asking the driver if they would like to share their profile with the nearby vehicle receiver subsystem (101). This ensures that users can make informed decisions about data sharing, enhancing the security and privacy of the system (100).

[0031] In addition to authorisation, the profile data stored in the vehicle (104) may comprise multiple data fields, and the system (100) can be configured to allow users to specify which data fields are to be shared with the vehicle receiver subsystem (101). This selective sharing can be controlled via authorisation instructions that are input through the computer subsystem (109). For example, the user might choose to share only their vehicle's make and model while withholding personal information such as their name or contact details. This feature is particularly useful for maintaining privacy while still enabling certain levels of interaction between vehicles (104). Additionally, the system (100) may be configured to record the identity of the vehicle receiver subsystem (101) once authorisation has been granted, allowing for subsequent requests to be approved automatically without requiring repeated authorisation.

[0032] Another embodiment allows the transponder (108) to conditionally transmit profile data based on parameters associated with the vehicle receiver subsystem (101). For instance, the vehicle receiver subsystem (101) might transmit parameters such as the driver’s age, gender, or vehicle type (e.g., civilian, government, etc.) when making a request for profile data. The transponder (108) could then evaluate these parameters and decide whether to transmit the profile data based on predefined criteria. This conditional data transmission allows for more refined control over the information exchange process, ensuring that data is only shared with vehicles (104) that meet certain criteria.

[0033] The system (100) may also be configured to facilitate two-way data exchange between the vehicle (104) and the vehicle receiver subsystem (101). In such an embodiment, once the initial profile data is exchanged, the system (100) could enable further interactions such as a two-way text-based chat. This feature allows drivers to communicate directly with each other via their vehicle displays (102, 110), enhancing the social aspects of the system (100). For example, two drivers who are members of the same car club might use the system (100) to chat about an upcoming event, coordinating details without needing to use external devices such as mobile phones.

[0034] The profile data exchanged between vehicles (104) and the vehicle receiver subsystem (101) can take various forms, including both text and imagery. Profile text may include information such as the driver’s name, vehicle model, or membership in a particular organisation. Profile imagery might consist of a photo of the driver, an image of the vehicle, or other relevant graphics. By supporting both text and imagery, the system (100) provides a rich and flexible platform for data sharing, accommodating different types of information based on the user’s preferences.

[0035] In an additional embodiment, the vehicle’s licence plate (112) is provided as an integral unit that includes the transponder (108) described herein. This integrated licence plate (112) allows the transponder (108) to be seamlessly incorporated into the vehicle (104) without requiring additional system configuration or the installation of separate components. The transponder (108) embedded within the licence plate (112) is configured to transmit the vehicle's profile data directly to the vehicle receiver subsystem (101) when in proximity. This integration offers several technical advantages, including a reduction in the complexity of the vehicle’s (104) electrical and communication systems, as well as enhanced durability and tamper resistance of the transponder (108). Since the licence plate (112) is typically positioned at an easily accessible location on the vehicle (104), the transponder (108) benefits from an optimal placement for signal transmission, ensuring reliable communication with the vehicle receiver subsystem (101). This embodiment further simplifies the installation process, making it easier for manufacturers to implement the system (100) across various vehicle models without the need for extensive modifications to the vehicle’s (104) existing infrastructure.

[0036] In some embodiments, the intra-vehicular data transmission and display system (100) is configured with an immobiliser or security enforcement module that ensures data exchange between vehicles (104) occurs only within the secured vehicle environment. In such an embodiment, the vehicle receiver subsystem (101) is integrated with the vehicle’s onboard immobiliser system, thereby disabling or restricting unauthorised peripheral devices such as mobile telephones or third-party recording devices when an in-car data session is initiated.

[0037] The security enforcement module may be configured to monitor whether an external call or data connection is attempted through a mobile device within the vehicle during an active session. If such an attempt is detected, the module may either block the connection or generate a log record of the attempt, optionally notifying the driver via the digital display (102). This arrangement ensures that the vehicle is treated as a secure and private environment for communication, preventing listening devices from capturing or relaying sensitive information.

[0038] In certain implementations, the immobiliser may extend its function to conditionally authorise inter-vehicle communication only when no external devices are active, thereby maintaining integrity of the vehicle-to-vehicle channel. For example, where the system (100) supports direct vehicle-to-vehicle data exchange without requiring a mobile phone, the immobiliser ensures that the communication path is isolated from external devices, thereby reducing the risk of interception.

[0039] In an exemplary system configuration, the vehicle receiver subsystem (101) comprises a processor, such as an ARM Cortex-A53 quad-core processor available from Texas Instruments or NXP, in operable communication with a system memory via a system bus. The system memory may include dynamic RAM, for example Micron DDR4 SDRAM, as well as non-volatile storage such as Samsung eMMC flash memory, wherein the volatile memory is used for temporary execution data and the non-volatile memory stores operating system instructions, application software, and user configuration data.

[0040] The vehicle receiver subsystem (101) further includes a network interface controller, such as a Qualcomm QCA9377 chip, configured to establish both wireless and wired data communication channels. In one embodiment, the network interface controller comprises a Wi-Fi module supporting IEEE 802.11ac protocols and a Bluetooth 5.0 transceiver. An NFC module, such as an NXP PN7150 NFC controller, may also be provided for short-range data transfer between proximate vehicles. A GPS receiver, for example a u-blox NEO-M8N multi-GNSS module, is integrated into the subsystem (101) and is configured to continuously report the geographic position of the vehicle to the server (106). The system bus further interconnects a graphicsprocessing unit, such as an ARM Mali-400 GPU, that drives the digital display (102), the graphics processing unit being responsible for rendering the user interface in real time according to the display instructions received from the controllers (103).

[0041] Input / output controllers may include a touchscreen controller, for example a Synaptics ClearPad IC, to support driver interaction via the digital display (102), and additional GPIO (general purpose input / output) controllers for interfacing with vehicle buttons or dials. In one configuration, a vehicle communication gateway, such as an ELM327 OBD-II interpreter IC, links the vehicle receiver subsystem (101) with the onboard diagnostics (OBD-II) system of the vehicle, thereby enabling the subsystem to obtain vehicle status information such as ignition state, speed, or fuel level, which may be used in managing when data transmission is permitted.

[0042] The server (106) may be implemented using a rack-mounted server system including at least one Intel Xeon Scalable processor, non-transitory system memory such as DDR5 ECC DRAM, and a database engine running on PostgreSQL or MySQL. The database (105) stores vehicle profiles, access control rules, and authorisation records. A communication module within the server (106) is configured with multiple network interface cards, such as Intel i210 Gigabit Ethernet controllers, to handle incoming GPS location reports and profile data requests from multiple vehicle receiver subsystems (101) concurrently.

[0043] In embodiments employing an image sensor (107), the image sensor may be a Sony IMX290 low-light CMOS sensor operably connected to the processor via a high-speed interface. An optical character recognition engine, implemented as program code running Tesseract OCR or as a dedicated FPGA module, is configured to process the captured image data, extract alphanumeric licence plate information, and transmit the result to the controllers (103) for matching against the database (105).

[0044] The transponder (108), when integrated into the licence plate (112), may comprise a radio frequency integrated circuit, such as an NXP UCODE 8 EPC Gen2 RFID IC, an antenna optimised for short-range vehicular communication, and a secure memory, for example Infineon MIFARE DESFire secure EEPROM, in whichthe vehicle profile data is stored. The radio frequency integrated circuit is configured to respond to interrogation signals from the vehicle receiver subsystem (101), selectively transmitting profile data in accordance with stored access rules. The secure memory may employ AES-128 or higher encryption to prevent unauthorised access to the profile data, thereby ensuring the security of the system.

[0045] In an exemplary method (200) of using the intra-vehicular data transmission and display system (100) according to an embodiment of the present invention, reference is made to Figure 2, which illustrates a flowchart depicting the steps involved in the operation of the system (100). The method (200) begins at step 201 , where the vehicle receiver subsystem (101) is powered on and initiates a system check to ensure that all components, including the digital display (102) and controllers (103), are functioning correctly. This initial step is crucial for verifying the operational readiness of the system (100) before it engages in any data transmission or interaction with other vehicles (104).

[0046] Once the system check is completed, the method (200) proceeds to step 202, where the vehicle receiver subsystem (101) actively monitors for the proximity of other vehicles (104). This is achieved by utilising the vehicle’s onboard GPS system or other location-detection technologies to determine the vehicle’s current location. The vehicle receiver subsystem (101) then transmits this location data to a central server (106), which continuously compares the location data of multiple vehicles (104) within a defined geographical area. In this step, the system (100) is configured to identify when another vehicle (104) comes within a predetermined proximity threshold, which triggers the subsequent steps in the method.

[0047] At step 203, upon detecting that another vehicle (104) is within the predefined proximity, the vehicle receiver subsystem (101) sends a request to the server (106) to retrieve the profile data associated with the nearby vehicle (104). This request is processed by the server (106), which accesses a database (105) containing stored profiles and retrieves the relevant data corresponding to the identified vehicle (104). The retrieved profile data typically includes various fields, such as the vehicle’s make and model, driver’s name, and other user-configured information.

[0048] In step 204, the vehicle receiver subsystem (101) evaluates the retrieved profile data to determine which fields are to be displayed on the digital display (102). This step may involve user-configured preferences or authorisation rules set by the vehicle (104) transmitting the profile data. For example, if the profile data includes fields that have been marked as private or restricted, the vehicle receiver subsystem (101) may be configured to exclude these fields from being displayed, thereby respecting the privacy preferences of the user.

[0049] Following the evaluation of the profile data, step 205 involves the actual display of the profile data on the digital display (102). The data is presented in a user- friendly interface, allowing the driver to view relevant information about the nearby vehicle (104). The digital display (102) may present the data in various formats, such as a simple text list, graphical elements, or a combination of both. The controllers(103) manage the display, ensuring that the information is shown clearly and that the user interface remains responsive to any further inputs or interactions.

[0050] In some embodiments, the method may proceed to step 206, where the vehicle receiver subsystem (101) initiates a two-way data exchange with the nearby vehicle(104). This step is particularly relevant if the system (100) is configured to support communication between vehicles (104). In this case, the driver may be presented with an option on the digital display (102) to send a message or request further information from the other vehicle (104). The system (100) then manages the transmission of this data, ensuring that it is securely and accurately exchanged between the two vehicles (104).

[0051] Step 207 involves the system (100) monitoring for any changes in proximity or new vehicles (104) entering the detection range. If a new vehicle (104) is detected, the method loops back to step 202, where the process of proximity detection, profile retrieval, and display is repeated for the new vehicle (104). This continuous monitoring ensures that the system (100) remains dynamic and responsive to the changing environment around the vehicle receiver subsystem (101).

[0052] Finally, the method concludes at step 208, where the vehicle receiver subsystem (101) returns to a standby mode after completing the data exchange anddisplay processes. In this mode, the system (100) conserves energy while remaining ready to activate again when another vehicle (104) enters the proximity or when the driver interacts with the digital display (102). This step maintains the system’s (100) efficiency and ensures that it does not drain the vehicle’s power resources unnecessarily.
