Description

Technical Field

[0001] This application relates to the field of vehicle communication technology, and in particular to a wiper system and control method with an integrated antenna. Background Technology

[0002] With the rapid development of intelligent connected vehicles and autonomous driving technologies, the demand for 5G communication, cellular vehicle-to-everything (C-V2X) vehicle-to-infrastructure (V2I) communication, and high-precision positioning via Global Navigation Satellite System (GNSS) is increasing. As a key component for achieving these functions, the performance of the vehicle-mounted communication antenna directly affects the overall communication quality and safety of the vehicle.

[0003] Currently, there are several main methods for installing vehicle communication antennas: First, integrating the antenna into the roof shark fin antenna module; second, placing the antenna inside the body panel or bumper area; and third, installing the antenna above the windshield or in the rear windshield area. These methods have the following drawbacks: Antenna signals are easily blocked and attenuated: Traditional vehicle antennas installed in the roof shark fin or inside the body panel are easily blocked by the vehicle's metal structure, especially in complex road conditions (such as tunnels, underground parking lots, and densely populated areas), resulting in severe signal attenuation and affecting the quality of 5G and C-V2X communication and GNSS positioning accuracy. Independent antennas require additional space on the roof and body panel, increasing the complexity of the overall vehicle design. Separate signal transmission cables are needed, resulting in longer cabling, more complex processes, increased production costs and maintenance difficulty, and may also affect the vehicle's aesthetics and increase wind resistance.

[0018] As an essential safety component of a vehicle, the windshield wiper system is typically installed in the windshield area to clear rainwater, snow, and other obstacles, ensuring the driver's visibility. Traditional windshield wiper systems have a single function: wiping water. The vehicle's antenna and wiper system are completely independent, supplied by different vendors, occupying different installation spaces, and have no structural or functional connection, making collaborative optimization impossible. During rainy driving, the frequent waving of the wipers can dynamically interfere with the antenna signal, making it impossible to dynamically optimize antenna parameters and communication signals based on the wiper's movement.

[0019] Figure 1 This application provides a wiper system with an integrated antenna. This embodiment is applicable to situations where the antenna and wiper mechanism are integrated for control. Figure 1 As shown, the system includes: an on-board controller 10, a windshield wiper 20 disposed on the outside of the vehicle windshield, and an antenna unit 30 integrated inside the windshield wiper 20; the antenna unit 30 is used to receive signals and transmit on-board data; the on-board controller 10 is used to control the movement of the windshield wiper 20 and to control the parameters of the antenna unit 30.

[0020] For example, antenna unit 30 can be a multi-frequency array antenna, supporting 4 / 5G (n77 / n78 bands, etc.), C-V2X (PC5 band), and GNSS (BeiDou + Global Positioning System (GPS) dual-mode) communication. It can also be a single-frequency antenna, a dual-frequency antenna, or only support one or more of C-V2X and GNSS bands, thereby adapting to the communication needs of different vehicle models.

[0021] The vehicle controller 10 can employ an automotive-grade microcontroller unit (MCU) (such as the NXPS32K3 series) as the system's control core, connecting to the wiper unit 20 and connecting to the antenna unit 30 via an in-vehicle wireless communication module and signal transmission components. Furthermore, the vehicle controller 10 can also be electrically connected to a power module. The vehicle controller 10 internally stores signal optimization control strategies, primarily used for real-time acquisition of parameters such as the wiper unit 20's swing angle, stopping position, and movement speed. It also acquires real-time communication quality information, such as obtaining communication parameters of the antenna unit 30, including signal strength, signal-to-noise ratio, and bit error rate, and can dynamically adjust antenna parameters.

[0022] Optionally, when the vehicle triggers a safety warning (such as a collision warning or speed limit warning) or an on-board safety signal, the on-board controller 10 can quickly send low-latency on-board data (such as driving routes and warning information) to the vehicle-road cooperative system or surrounding vehicles through the antenna unit 30, thereby improving the overall vehicle safety performance.

[0023] Building upon this foundation, integrating the vehicle-mounted antenna into the wiper unit reduces antenna space requirements and lowers overall vehicle costs. Furthermore, it leverages the signal reception advantages of the wiper unit's location, enabling coordinated control of wiper and antenna parameters via the vehicle controller, thus improving the quality of the vehicle antenna's communication signal. This system is suitable for intelligent connected vehicles such as passenger cars and commercial vehicles, achieving deep integration of the wiper blade assembly and the vehicle communication antenna. Simultaneously, through dynamic signal optimization, it enhances the communication stability of 5G, C-V2X, and GNSS high-precision positioning.

[0024] In one embodiment, the vehicle controller 10 is specifically used to collect the communication quality of the antenna unit 30 in real time, control the movement of the wiper device 20 according to the communication quality, and adjust the parameters of the antenna unit 30 according to the movement state of the wiper device 20 and / or the communication quality.

[0025] For example, the vehicle controller 10 can control the wiper device 20 based on the communication quality of the antenna unit 30. For instance, when the communication quality is below a preset threshold (e.g., signal strength ≤ -100dBm, bit error rate ≥ 1%), the wiper can be controlled to remain at the optimal signal position (e.g., a preset optimal signal reception angle, such as a 45° swing angle) until the communication quality recovers above the preset threshold, at which point the wiper returns to its default position or normal swing state. Furthermore, the vehicle controller 10 can also adjust the transmit power, receive gain, and beam pointing of the antenna unit 30 according to a preset strategy based on the motion state and parameters of the wiper device 20, and / or the current communication quality information. For example, when the communication quality is low, the parameters of the antenna unit 30 can be adjusted to improve communication quality; when the wiper device 20 needs to swing frequently (e.g., during heavy rain), the parameters of the antenna unit 30 can be adjusted to appropriately reduce communication quality. Based on this, coordinated control of the wiper device 20 and the antenna unit 30 is achieved.

[0026] In one embodiment, the system further includes: an in-vehicle wireless communication module disposed inside the vehicle; the in-vehicle wireless communication module is connected to the in-vehicle controller 10 and connected to the antenna unit 30 through a signal transmission component; the in-vehicle wireless communication module is used to decode the signals received by the antenna unit 30, and to encode and send in-vehicle data to the antenna unit 30; the in-vehicle controller 10 is also used to generate in-vehicle data and process the decoded signals.

[0027] For example, the vehicle-mounted wireless communication module can be installed inside the vehicle's dashboard, employing a vehicle-grade high-reliability communication module (such as a Qualcomm SA522 5G module or a self-developed module). It integrates a 5G communication unit, a C-V2X communication unit, and a GNSS positioning unit. This module establishes a bidirectional electrical connection with the antenna unit 30 via a signal transmission component. This connection is used to demodulate and decode the wireless signals received by the antenna unit 30, as well as to encode and transmit vehicle data (such as vehicle status and safety warning information). The feed terminal of the antenna unit 30 is connected to the signal transmission component to enable signal transmission and interaction.

[0028] The vehicle wireless communication module can communicate with the vehicle controller 10 via Controller Area Network (CAN) or Ethernet. It can provide real-time feedback on current communication quality information (such as signal strength / signal-to-noise ratio / bit error rate) to the vehicle controller 10. At the same time, it can receive antenna parameter (such as transmit power / receive gain) adjustment commands sent by the vehicle controller 10 and transmit them to the antenna unit 30.

[0029] In one embodiment, the antenna unit 30 is integrated inside the wiper blade assembly plate of the wiper device 20, and the wiper blade assembly is a wiper blade spoiler or a wiper blade rubber strip.

[0030] For example, the scraper assembly includes a scraper strip and a scraper spoiler, and the antenna unit 30 can be integrated inside the scraper strip. It can also be integrated inside the scraper spoiler.

[0031] Taking the wiper blade assembly integrated inside the rubber strip as an example, the antenna unit 30 can adopt a flexible antenna design. The antenna radiator is made of flexible printed circuit (FPC) material, embedded in the internal cavity of the wiper blade rubber strip, and wrapped with a waterproof elastomer material on the outside. The signal transmission component uses FPC instead of shielded coaxial cable, which makes the wiring more flexible, fits better to the structure of the wiper arm, and further reduces signal attenuation.

[0032] In one embodiment, the scraper spoiler is made of high-temperature resistant, waterproof, and insulating engineering plastic, with a pre-reserved mounting cavity inside. The antenna unit 30 is embedded in the mounting cavity and sealed and fixed with waterproof potting compound.

[0033] For example, the antenna unit 30 is integrated inside the wiper blade spoiler. Specifically, the wiper blade spoiler can be made of high-temperature resistant, waterproof, and insulating engineering plastic (such as polycarbonate (PC) / acrylonitrile butadiene styrene (ABS) alloy), with a pre-reserved mounting cavity inside. After the antenna unit 30 is embedded in the mounting cavity, it is sealed and fixed by waterproof potting compound to ensure the stability and sealing of the antenna unit 30 when the wiper is working (rainwater washing, high-speed swing).

[0034] In one embodiment, the antenna unit 30 can also be integrated inside the wiper blade frame. Regardless of where it is integrated into the wiper blade assembly, the key is to ensure that the signal transmission and reception of the antenna unit 30 is not affected by the operation of the wiper blade and that it has good waterproof and insulation properties.

[0035] In one embodiment, the radiator of the antenna element 30 is made of flexible copper foil, conforming to the arc-shaped structure design of the wiper spoiler. This design maximizes signal reception space in the windshield area without affecting the wiper's swing amplitude.

[0036] In one embodiment, the wiper device 20 includes a wiper arm, a wiper blade assembly, and a drive mechanism; the vehicle controller 10 is connected to the drive mechanism; one end of the wiper arm is connected to the drive mechanism, and the other end of the wiper arm is detachably connected to the wiper blade assembly; the wiper arm is made of aluminum alloy and has a wiring groove inside for laying signal transmission components, and the inner wall of the wiring groove is provided with an insulating protective layer.

[0037] For example, the wiper device 20 can be a wiper device 20 located on the windshield of a vehicle, including a wiper arm, a wiper blade assembly, and a drive mechanism. The wiper arm can be made of lightweight aluminum alloy, and may have a wiring groove inside for laying signal transmission components. The inner wall of the wiring groove is provided with an insulating protective layer to prevent the metal material of the wiper arm from shielding or interfering with the antenna signal. The drive mechanism can be driven by a stepper motor and is electrically connected to the vehicle controller 10. It can receive control signals from the vehicle controller 10, adjust the wiper swing angle and swing speed, and at the same time, it can feed back the current swing position and attitude information of the wiper (such as swing angle and rest position) to the vehicle controller 10.

[0038] In one embodiment, the signal transmission component includes a shielded coaxial cable or a flexible circuit board; one end of the signal transmission component is welded and fixed to the feed end of the antenna unit, and the other end extends through the wiring groove into the vehicle body and is connected to the vehicle wireless communication module; the outer layer of the signal transmission component is provided with a waterproof protective sleeve.

[0039] Figure 2 This is a schematic diagram of another wiper system with an integrated antenna provided in one embodiment. Figure 2 As shown, the vehicle controller 10 can control the movement of the wiper unit 20 by controlling the drive mechanism 23 in the wiper unit 20. Furthermore, the vehicle controller 10 can control the parameters of the antenna unit 30 through the vehicle wireless communication module 40 and the signal transmission component 50. The power module 60 can supply power to the vehicle controller 10, the vehicle wireless communication module 40, the drive mechanism 23, and the antenna unit 30.

[0040] The wiper unit 20 includes a wiper arm 21, a wiper blade assembly 22, and a drive mechanism 23. The wiper blade assembly 22 is the core integrated component and may specifically include a wiper blade frame (not shown), a wiper blade rubber strip 202, and a wiper blade spoiler 201. One end of the wiper arm 21 is connected to the drive mechanism 23, and the other end is detachably connected to the wiper blade assembly 22. The connection is waterproof and sealed to prevent rainwater from seeping into the wiring duct and damaging the signal transmission component 50. The antenna unit 30 may be integrated inside the wiper blade spoiler 201 or the wiper blade rubber strip 202.

[0041] The power module 60 can be an on-board 12V power conversion module, which integrates overvoltage, overcurrent and short-circuit protection circuits to ensure stable operation of the system when the vehicle voltage fluctuates. At the same time, the power module 60 is connected to the on-board controller 10 and can receive power control commands from the on-board controller 10 to realize on-demand power supply to the antenna unit 30 and the on-board wireless communication module 40 (such as cutting off unnecessary power supply when the vehicle is turned off to reduce energy consumption).

[0042] The vehicle controller 10 can perform the following functions: (1) Real-time acquisition of the status information of the wiper device 20: The current swing angle, stationary position, movement speed and other parameters are obtained through the position sensor of the drive mechanism 23; (2) Real-time acquisition of communication quality information: The vehicle-mounted wireless communication module 40 acquires the current antenna unit 30's signal strength, signal-to-noise ratio, bit error rate and other communication parameters. (3) Dynamically adjust antenna parameters: Based on the wiper movement status and / or communication quality information, according to the preset strategy, send adjustment instructions to the vehicle wireless communication module 40 to adjust the transmit power, receive gain or beam pointing of the antenna unit 30; (4) Emergency control: When the communication quality of antenna unit 30 is lower than the preset threshold, control drive mechanism 23 to keep the wiper at the optimal signal position until the communication quality recovers to above the threshold, and then resume normal wiper swing. (5) Safety Linkage: When the vehicle triggers a safety warning or vehicle safety signal, the vehicle wireless communication module 40 is controlled to quickly send low-latency warning information to the vehicle-road cooperative system or surrounding vehicles through the antenna unit 30, thereby improving the overall vehicle safety performance. The integrated antenna wiper system provided in this application embodiment is an intelligent connected vehicle wiper system, wherein the antenna unit is integrated inside the wiper assembly, forming an integrated structure with the wiper system. On this basis, dynamic signal optimization based on wiper movement status and communication quality can be realized, that is, the vehicle controller collects status information such as wiper swing angle and stopping position in real time, as well as communication quality information, and dynamically adjusts the antenna's transmission power, receiving gain or beam pointing according to a preset strategy, and controls the wiper to stop at the optimal signal position when the communication quality is lower than the threshold.

[0043] Furthermore, artificial intelligence algorithms can be introduced, such as those based on historical communication data and road condition information, to predict signal change trends in advance and proactively adjust antenna parameters and wiper movement status, thereby further improving the response speed and accuracy of signal optimization. The wiper system with integrated antenna in this embodiment of the application has the following advantages: By integrating the antenna unit into the scraper assembly and placing it in the windshield area, the shielding interference of the vehicle's metal parts can be avoided, resulting in a smoother communication path. This can improve the signal strength of 5G and C-V2X by 10-15 dBm and the GNSS positioning accuracy to the centimeter level, effectively solving the problems of easy signal blockage and severe attenuation of traditional vehicle antennas. The antenna unit does not require additional space on the roof or body sheet metal, does not change the vehicle's exterior design, does not increase the vehicle's wind resistance, and at the same time reduces the antenna installation and wiring processes, thereby reducing the overall vehicle production cost. By combining the characteristics of windshield wiper swing or movement, the antenna parameters are dynamically adjusted through the vehicle controller to adapt to complex road conditions such as turns, slopes, and rain obstruction, ensuring the continuity and stability of the communication link and meeting the high reliability communication requirements of intelligent connected vehicles and autonomous driving. The antenna unit features a waterproof, high-temperature resistant, and wear-resistant design, making it suitable for the working environment of windshield wipers and ensuring a long service life. It is also compatible with existing windshield wiper structures and vehicle communication systems, eliminating the need for large-scale vehicle modifications. It is suitable for various intelligent connected vehicle models and facilitates mass production.

[0044] Figure 3 This is a flowchart illustrating a control method for a windshield wiper system with an integrated antenna, as provided in one embodiment. This method can be applied to an onboard controller in a windshield wiper system with an integrated antenna; the windshield wiper system with an integrated antenna can be found in any of the embodiments described above. Figure 3 As shown, the method specifically includes the following steps: S110. Control the movement of the wiper device and control the parameters of the antenna unit.

[0045] Building upon this foundation, the vehicle-mounted antenna is integrated within the wiper unit, reducing antenna space requirements and lowering overall vehicle costs. Furthermore, it leverages the signal reception advantages of the wiper unit's location, enabling coordinated control of wiper and antenna parameters via the vehicle controller, thus improving the quality of the vehicle-mounted antenna's communication signal. This system is suitable for intelligent connected vehicles such as passenger cars and commercial vehicles, achieving deep integration of the wiper blade assembly and the vehicle-mounted communication antenna. Simultaneously, through dynamic signal optimization, it enhances the communication stability of 5G, C-V2X, and GNSS high-precision positioning.

[0046] In one embodiment, controlling the movement of the windshield wiper device includes: The communication quality of the antenna unit is collected in real time; The movement of the wiper device is controlled based on the communication quality.

[0047] In one embodiment, the parameters for controlling the antenna element include: The parameters of the antenna unit are adjusted according to the motion state of the wiper device and / or the communication quality.

[0048] In one embodiment, the method further includes: The vehicle controller generates vehicle data; The vehicle-mounted wireless communication module encodes the vehicle-mounted data and sends it to the antenna unit.

[0049] In one embodiment, the method further includes: The vehicle-mounted wireless communication module decodes the signals received by the antenna unit; The vehicle controller processes the decoded signal.

[0050] The following illustrates the workflow of a wiper system with an integrated antenna.

[0051] S1. System Initialization: After the vehicle starts, the power module supplies power to all components of the system, the vehicle controller and vehicle wireless communication module complete initialization, the antenna unit starts and establishes a connection with the vehicle wireless communication module, and the drive mechanism resets to the initial position (the default position for signal reception).

[0052] S2. Status Acquisition: The vehicle controller collects real-time status information such as wiper swing angle and stopping position from the drive mechanism, and at the same time collects communication quality information (signal strength, signal-to-noise ratio, bit error rate) from the vehicle wireless communication module.

[0053] S3. Signal Judgment and Optimization: The vehicle controller compares the collected communication quality information with the preset threshold. If the communication quality meets the requirements (e.g., signal strength > -100dBm, bit error rate < 1%), the current operating parameters of the antenna unit are maintained, and the wipers swing normally. If the communication quality is lower than the preset threshold, the optimal signal parameters are calculated based on the current wiper swing position and attitude. Commands are sent to the vehicle wireless communication module to adjust the transmit power, receive gain, or beam pointing of the antenna unit. At the same time, the wipers can be controlled to stay at the optimal signal position until the communication quality is restored.

[0054] S4. Dynamic Adaptation: During vehicle operation, the windshield wipers swing normally according to the rain conditions. The onboard controller tracks the movement status and communication quality of the wipers in real time and continuously adjusts the antenna parameters to ensure that the communication signal is always in the optimal state throughout the entire process of the wipers swinging. For example, when the wipers swing to the upper edge of the windshield (the area with the least signal obstruction), the antenna receiving gain is increased; when the wipers swing to the lower edge (the area with greater signal obstruction), the transmission power is appropriately increased to compensate for signal attenuation.

[0055] S5. System Shutdown: After the vehicle is turned off, the power module cuts off unnecessary power to the system, the antenna unit 30 and the vehicle wireless communication module stop working, the wipers reset to their initial positions, and the system enters a sleep state. The control method provided in this application embodiment can be applied to the wiper system with integrated antenna provided in any of the above embodiments, and has the corresponding functions and beneficial effects.
