Description

Technical Field

[0001] This application belongs to the field of vehicle networking, and in particular relates to a V2X vehicle unit. Background Technology

[0002] With the development of intelligent transportation systems, vehicle-to-everything (V2X) technology has become a key technology for improving road safety, traffic efficiency, and driving experience. V2X technology enables communication between vehicles (V2V), between vehicles and infrastructure (V2I), between vehicles and pedestrians (V2P), and between vehicles and networks (V2N), providing drivers with real-time traffic information, safety warnings, and navigation assistance. However, existing V2X onboard units (OBUs) have the following problems:

[0003] Human-machine interaction issues: Current OBU systems typically require the use of a tablet or smartphone. This separate design not only increases the cost of the additional display screen but also falls short in terms of ease of operation and user experience. Furthermore, the lack of voice interaction functionality limits the driver's interaction options while driving, increasing the risk of driver distraction.

[0004] Installation issues: Existing OBU systems often require an external antenna, with the main unit and shark fin antenna being separate. This not only affects the vehicle's appearance but also requires vehicle modification during installation, increasing the complexity and cost of the installation process.

[0005] Cost issues: Due to the aforementioned split design and the need for external antennas, the cost of existing OBU systems is higher than expected, which limits the popularization and application of V2X technology.

[0006] Power supply issue: Existing OBU systems typically use a dedicated power interface and custom power cable. This design limits system compatibility, making it difficult for OBUs to be used interchangeably across different vehicle models and increasing user costs.

[0007] Power consumption issue: Existing OBU systems have high power consumption, usually around 10W, which is a considerable burden on the vehicle's battery system, especially under long-term use, and will significantly shorten battery life.

[0008] Positioning issues: Due to the instability or absence of GNSS signals, existing OBU systems have significant errors in positioning accuracy, which directly affects the accuracy of safety warnings and navigation assistance functions provided by V2X systems.

[0009] RTK account issues: Existing OBU systems often rely on RTK (Real-Time Motion Measurement) accounts for high-precision positioning, and these accounts are usually charged annually, increasing the long-term usage costs for users.

[0010] In summary, existing V2X onboard units (OBUs) suffer from numerous problems in areas such as human-machine interaction, ease of installation, cost control, power compatibility, power consumption, positioning accuracy, and service fees. These issues limit the development and widespread adoption of V2X technology. Therefore, it is necessary to develop a new type of V2X onboard unit to address these problems, improve user experience, reduce operating costs, and enhance system reliability and accuracy.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0035] To facilitate understanding of the solutions described in the embodiments of this application, the following explanations are provided for some terms that may be used in the embodiments of this application:

[0036] V2X: V2X technology is a key technology for intelligent transportation systems. It enables communication between vehicles, between vehicles and base stations, and between base stations, thereby obtaining a range of traffic information such as real-time road conditions, road information, and pedestrian information. This improves driving safety, reduces congestion, increases traffic efficiency, and provides in-vehicle entertainment information.

[0037] OBU: OBU (short for On board Unit) literally means vehicle-mounted unit. It uses DSRC (Dedicated Short Range Communication) technology to communicate with roadside units (RSU).

[0038] This application provides a V2X vehicle-mounted unit designed to address problems in existing technologies, such as inconvenient human-machine interaction, complex installation, high cost, and high power consumption. The V2X vehicle-mounted unit in this embodiment provides an improved solution through integrated design, optimized power management, and flexible information output methods.

[0039] See Figure 1 In this embodiment, the V2X vehicle-mounted unit includes an optional information output cover 21, which is coupled to the V2X vehicle-mounted unit body 10 and used to output road traffic safety information based on V2X module signals. The information output cover 21 is connected to the body through a standard interface, making installation and maintenance more convenient. The standard interface can be a serial port or a dedicated display interface, and the interface uses a spring probe for connection.

[0040] For example, when using a probe to connect the cover plate for the display function to the main body, a spring probe makes contact during installation. Alternatively, in an optional embodiment, an OBU decorative cover can be installed on the front shell of the OBU when the display is not required.

[0041] The V2X module within the unit can output V2X module signals, including a control unit and a V2X communication module. The V2X communication module communicates with V2X roadside units and other vehicle-to-everything (V2X) on-board communication terminals via a V2X antenna, while the control unit is responsible for processing the received communication information and outputting V2X module signals.

[0042] Overall, the product can integrate multiple functional modules, including a control unit, a V2X communication module, a wireless communication module, a positioning module, an audio input module, an audio output module, a Bluetooth / WiFi module, a USB interface module, and a video interface module. The communication terminal also includes a built-in V2X antenna, a wireless communication antenna, and a positioning antenna. The control unit is responsible for controlling each module, data fusion, scene algorithm analysis, and other tasks to realize applications in scenarios such as vehicle-road cooperation.

[0043] In some embodiments, the V2X onboard unit also includes a positioning module connected to the control unit, which enables high-precision positioning via a positioning antenna. This design improves positioning accuracy and helps enhance the performance of the V2X system.

[0044] See Figure 2 In other embodiments, the information output cover is an audio module 22, which enables voice input, recognition, and voice broadcasting functions, and can broadcast V2X scene data and human-machine interaction functions in real time. This design allows the V2X vehicle unit to communicate with the driver via voice without visual interaction, improving driving safety and convenience.

[0045] See also Figure 1 In other embodiments, the information output cover is a display screen 21, used to display road traffic safety information based on V2X module signals. This display screen's configurable display modules do not rely on high-precision maps; lane lines in the display interface adapt to vehicle position, navigation functions are removed, and only traffic participants affecting the vehicle's movement are displayed. This optimized display scheme makes the information more intuitive, facilitating quick understanding and reaction by the driver. The display screen can then be connected to the main body 10 via a video interface module, which connects to the display screen 21 to achieve real-time transmission of V2X scene data.

[0046] Optionally, when the vehicle-mounted unit communicates with the roadside unit, it interacts through a customized protocol. The roadside unit sends information according to the vehicle's needs. The roadside unit can filter information relevant to the vehicle from the acquired information based on preset rules and send it to the vehicle-mounted unit. This information can be content that can be directly converted for output, or content that needs to be processed by the control unit before output; this application does not impose specific restrictions. To display more comprehensive and effective information, it is recommended that the control unit control the overall output content. In this case, the vehicle-mounted unit can integrate key information from multiple sources and output it. However, this places slightly higher demands on the control unit compared to the direct display solution, and can be flexibly configured based on actual needs. When integrating display information from multiple data sources, the control unit needs to consider the relative positional relationships between targets around the vehicle. When displaying on the interface, key content should be displayed using simple and intuitive icons, without involving maps, especially high-precision maps.

[0047] In some embodiments, the information output cover also includes a voice module for outputting road traffic safety reminders. This function can remind the driver via voice when the display screen is not in operation, ensuring the continuity and integrity of information delivery.

[0048] The V2X vehicle unit in this embodiment also includes a built-in V2X antenna, which is coaxially connected to the V2X communication module and is vertically configured. The distance between the main and secondary antennas meets the isolation requirements and is greater than the width of a common mobile phone, so as to achieve optimal communication performance.

[0049] The V2X onboard unit also includes a wireless communication module and a power management module. The wireless communication module is mounted on the control unit, enabling collaborative applications between the vehicle, the road, and the cloud. The power management module is responsible for power and consumption management, performing time-sharing low-power control during OBU use, such as automatically reducing display brightness when there is no need to broadcast V2X messages.

[0050] In this embodiment, the V2X vehicle unit supports windshield adhesive mounting using 3M adhesive, enabling quick and easy installation. Furthermore, it is attached to the display screen via detachable clips, resulting in a rigid assembly that ensures stable connector connection.

[0051] The V2X onboard unit in this embodiment has a self-organizing network function, enabling direct communication between vehicles even without roadside unit support, thus improving the system's robustness and coverage. Furthermore, this embodiment proposes an artificial intelligence-based scene algorithm analysis. Through deep learning technology, it analyzes the data received by the V2X communication module to provide more accurate safety warnings and driving assistance.

[0052] The positioning module is mounted on the control unit and achieves high-precision positioning through the positioning antenna. To meet the optimal positioning performance, the GNSS antenna is placed horizontally and adjusted in conjunction with the main structure to achieve optimal positioning accuracy.

[0053] The wireless communication module is mounted on the control unit and enables collaborative applications of vehicle, road, and cloud through wireless communication, allowing the communication terminal to perform functions such as remote configuration and platform information interaction.

[0054] The V2X vehicle unit also includes a Bluetooth / WiFi module and a USB communication interface module, which can realize real-time transmission of V2X scene data;

[0055] The OBU also includes a power management module for power and consumption management, performing time-sharing low-power control during OBU use. For example, it automatically reduces display brightness when there is no need for V2X message broadcasting. It also performs low-power sleep mode when there is no need for V2X or other wireless communication. Optionally, the OBU power interface uses a Type-C interface.

[0056] The V2X vehicle unit proposed in this application features a simple UI interface, facilitating driver assistance and helping drivers avoid dangers. This product does not rely on high-precision maps, and lane lines adapt to the vehicle's position, eliminating navigation functions. The UI interface only displays traffic participants that affect the vehicle's movement, such as collision warnings for vulnerable road users, which can be displayed concisely and intuitively. It also supports voice broadcasting, making it easy for users to quickly grasp key warning information. In addition, the OBU does not require a display screen, so the screen can be in sleep mode or equipped with a cover that only supports voice functions. In this case, voice broadcasting for V2X scenarios can also be performed through the OBU's voice output module.
