TWM673005U - Parking wheel assist warning system - Google Patents

Abstract

This invention discloses a parking wheel auxiliary defense warning system, which includes a vehicle condition change defense module installed on the vehicle. The vehicle condition change defense module includes a radar sensing module, a signal processing module and a defense warning module. Among them, the radar sensing module includes a wheel-following defense sensing radar. The wheel-following defense sensing radar is installed on the wheel of the vehicle and is used to sense the outside as the wheel moves. When one of the wheels comes into contact with an external object at a predetermined distance, resulting in a wheel condition change, the wheel follows the wheel. The wheel-mounted protection radar detects changes in wheel intrusion in real time and generates a wheel intrusion error signal. The signal processing module, based on the wheel intrusion error signal, drives the protection warning module to generate corresponding protection warning information indicating wheel damage. This allows the wheel-mounted protection radar to detect low obstacles on the side of the wheel and provide the driver with real-time low obstacle warning information, thereby reducing the risk of collision and avoiding financial losses caused by wheel rim scratches.

Description

Parking wheel assist warning system

This invention relates to a parking wheel-assisted safety warning system, specifically a wheel-assisted safety warning technology that uses wheel-mounted sensor radars to more comprehensively detect obstacles around the vehicle.

As far as we know, a learning reversing radar device is primarily mounted on a vehicle's rear bumper. It activates when the vehicle is reversing and detects obstacles within a limited distance behind the vehicle. When the reversing radar detects an obstacle behind the vehicle, it emits a short- and long-frequency tone to warn the driver of the distance between the obstacle and the vehicle, thereby prompting the driver to avoid the obstacle. While this learning reversing radar can detect and warn of obstacles behind the vehicle, it cannot detect low obstacles beside the wheels. For example, when a vehicle is parked in a curbside parking space, the steering wheel may not be straightened or the steering wheel may be improperly operated, causing the right front wheel to turn to the right. As a result, the vehicle is more likely to hit the curb wall of the curbside adjacent to the curbside parking space (as shown in Figure 9) or the curb wall of the curbside flowerbed adjacent to the curbside parking space (as shown in Figure 10), resulting in scratches on the rim and causing financial losses. Furthermore, when the vehicle is stuck in traffic or stopped at a traffic light, the left front wheel may veer to the left due to the steering wheel not being straightened or improper steering operation. This can easily cause the wheel and rim to strike the outer side wall of the safety island as the vehicle moves (as shown in Figure 11). This can also cause damage due to wheel scratches, resulting in inconvenience and trouble in detecting obstacles while the vehicle is moving.

To address the above shortcomings, relevant technology companies have developed the following patents:

1. Patent No. I614515, "Environmental Identification System for Automotive Millimeter-Wave Radar," includes a millimeter-wave radar device that detects obstacles outside the vehicle and converts the detection results into reflected information. An energy intensity calculation device, an anti-noise calculation device, and an obstacle width calculation device are each connected to the millimeter-wave radar device to receive the reflected information. Each device calculates the energy intensity, signal-to-noise ratio, and width of the obstacle, and transmits this information to a control device. The control device then integrates the energy intensity, signal-to-noise ratio, and width information to identify the type of obstacle. While the patent can effectively identify various obstacles and enable the vehicle to respond immediately, it lacks a sensor and warning system for low obstacles on the side of the wheel. This can still result in wheel rims colliding with adjacent parking spaces that are higher than roadside flower beds or sidewalk walls, causing damage and property losses.

2. Patent No. I674424, "Radar Detection Device Installed in a Vehicle Rearview Mirror," is a radar detection device installed in a vehicle's rearview mirror. It comprises a radar module, a control module, and a warning module. The control module is connected to the radar module signal and the warning module information, respectively. The control module controls or determines whether there are objects within the radar module's sensing range. When an object is detected within the radar's sensing range, the warning module issues a warning signal. While the patent can effectively identify obstacles and issue a warning signal to avoid collisions, it also lacks a sensor and warning function for low obstacles on the side of the wheel. This makes it more likely that the wheel and rim will collide with adjacent parking spaces that are higher than roadside flower beds or sidewalk walls, causing rim scratches and financial losses.

Given that the known reversing radar technology and the aforementioned patent application lack a sensory warning system for low obstacles beside the wheels, the aforementioned inconvenience and annoyance arise from this lack of sensing. It is clear that both the known reversing radar technology and the aforementioned patent application are not perfect and still require further improvement. Therefore, through continuous research and development, the present inventors have finally developed a device that differs from the aforementioned known technology and offers enhanced functionality.

The first purpose of this new device is to provide a parking wheel assist warning system. This system, primarily through its low obstacle sensing and warning function, can more comprehensively detect obstacles around the vehicle, particularly low obstacles located in the vehicle's blind spots. This provides the driver with real-time obstacle warning information, thereby reducing the risk of collisions and preventing financial losses caused by wheel rim scratches. The technical means for achieving the first purpose of this novel device include a vehicle condition change protection module installed on a vehicle, the vehicle condition change protection module includes a radar sensing module, a signal processing module and a protection warning module; wherein the radar sensing module includes a wheel-following protection sensing radar, and the wheel-following protection sensing radar is installed on the wheel of the vehicle to move toward the outside as the wheel moves. When a wheel comes into contact with an object within a predetermined distance, causing a wheel condition change, the wheel-following protection radar immediately detects the change and generates a wheel intrusion change signal. Based on the wheel intrusion change signal, the signal processing module drives the protection warning module to generate corresponding protection warning information indicating wheel damage.

The second objective of this invention is to provide a wheel-assisted parking warning system with omnidirectional radar sensing to enhance obstacle detection accuracy. The technical means for achieving this second objective include a vehicle-mounted vehicle condition change protection module, which includes a radar sensing module, a signal processing module, and a warning module. The radar sensing module includes a wheel-following protection radar, which is mounted on the vehicle's wheels and is designed to follow the movement of the wheels and detect obstacles. When one of the wheels comes into contact with a foreign object within a predetermined distance, causing a wheel condition change, the wheel-following defense sensing radar immediately detects the change and generates a wheel-following foreign object intrusion change signal. Based on the wheel-following foreign object intrusion change signal, the signal processing module drives the defense warning module to generate corresponding defense warning information indicating wheel damage from foreign object intrusion. The at least one wheel-following defense sensing radar is plural and is arranged around the wheel rim at equal central angles.

The third purpose of the present invention is to provide a parking wheel auxiliary defense warning system with a cooperative defense function to project light to the area near the wheels to enhance parking safety. The technical means to achieve the third purpose of the present invention includes a vehicle condition change defense module installed on the vehicle, and the vehicle condition change defense module includes a radar sensing module, a signal processing module and a defense warning module; wherein, the radar sensing module includes a wheel follower defense sensing radar, and the wheel follower defense sensing radar is installed on the wheel of the vehicle to follow the wheel to move toward the outside. When one of the wheels comes into contact with a foreign object within a predetermined distance, resulting in a wheel condition change, the wheel-following protection radar immediately senses the wheel intrusion change and generates a wheel intrusion change signal. Based on the wheel intrusion change signal, the signal processing module drives the protection warning module to generate corresponding protection warning information indicating wheel damage from foreign object intrusion. The system further includes a collaborative protection module, which includes an auxiliary lighting device. When the vehicle condition change protection module is activated, the auxiliary lighting device is synchronously activated to project light toward an area near at least one of the plurality of wheels.

To help you, the Review Committee, better understand the overall technical features of this novel device and the technical means for achieving its objectives, a specific embodiment is provided with accompanying diagrams for detailed description as follows:

Referring to Figures 1-3 and 7-11, a specific embodiment for achieving the first objective of the present invention includes a vehicle condition change protection module 20 that can be installed on a vehicle 10. The vehicle condition change protection module 20 includes a radar sensing module 21, a signal processing module 22 informationally connected to the radar sensing module 21, and a protection warning module 23 electrically connected to the signal processing module 22. The main technical features of this embodiment are: the radar sensing module 21 includes at least one wheel-follower protection sensing radar 210, and the at least one wheel-follower protection sensing radar 210 is installed on the body of the vehicle 10. At least one wheel 12 on the vehicle 11 is provided with a wheel-following security sensor radar 210 (for example, as shown in FIG2 , at least one front wheel or at least one rear wheel is provided; or as shown in FIG7 , at least one wheel-following security sensor radar 210 is preferably provided on each of the two front wheels or the two rear wheels; or as shown in FIG8 , at least one wheel-following security sensor radar 210 is more preferably provided on each of the two front wheels and the two rear wheels; a more economical, practical, and effective embodiment is to provide at least one wheel-following security sensor radar on each of the front and rear wheels closer to the passenger seat). 210), is used to sense the outside of at least one wheel 12 as it moves from at least one wheel 12. When at least one wheel 12 approaches at least one foreign object 1 (such as a low side obstacle, such as a protruding sidewall 1a on the outside of a sidewalk, as shown in FIG9 ; a protruding sidewall 1b on the outside of a roadside flowerbed, as shown in FIG10 ; or a protruding sidewall 1c on the outside of a safety island, as shown in FIG11 ) and reaches a predetermined distance, thereby forming at least one wheel condition change, the at least one wheel condition change is a foreign object approaching change at least one wheel, and the at least one wheel following defense sensing radar 210 immediately senses the at least one foreign object 1 approaching at least one wheel 1. 2. Based on at least one wheel being affected by a foreign object, a foreign object intrusion error signal is generated. The signal processing module 22 drives the defense warning module 23 to generate corresponding defense warning information indicating that at least one wheel is being damaged by a foreign object (e.g., outputting a warning signal and/or warning information such as left or right direction or indicating the wheel and the intrusion distance in the form of audio, voice, flashing light, and/or display information, and the frequency of the audio or flashing light signal gradually increases as the intrusion distance gradually decreases. When the intrusion distance reaches a predetermined minimum value, the audio signal becomes a long tone).

Referring to Figures 2-4 , in a more specific embodiment of the present invention, at least one wheel-following security sensor radar 210 is mounted on the rim 13 of at least one wheel 12. In the embodiment shown in Figure 2 , a wheel-following security sensor radar 210 is mounted on the rim 13 of each of the front and rear wheels 12, and each wheel-following security sensor radar 210 is mounted (e.g., bonded or locked) on a center cover 130 in the center of the rim 13. In a preferred embodiment, the wheel-follower security sensor radar 210 is fixedly attached to the center cover 130 of the rim 13. The center cover 130 is provided with a through hole for the wheel-follower security sensor radar 210 to project the sensing signal outward.

Please refer to Figures 1 and 4 for a specific embodiment that achieves the second objective of the present invention. In addition to incorporating the overall technical content of the first embodiment described in the previous two paragraphs, the at least one wheel-followed security sensor radar 210 is provided in a plurality. These plurality of wheel-followed security sensor radars 210 are arranged in a circular pattern at equal central angles on the wheel rim 13. In a preferred embodiment, a plurality of wheel-followed security sensor radars 210 are installed on each of the two front wheels 12. In a preferred embodiment, as shown in Figure 4, three wheel-following security sensor radars 210 are installed on each wheel 12. These three wheel-following security sensor radars 210 are mounted (e.g., bonded or locked) on a center cover 130 located in the center of the rim 13. In one preferred embodiment, the three wheel-following security sensor radars 210 are fixedly attached to the center cover 130 of the rim 13. The center cover 130 has three holes through which the three wheel-following security sensor radars 210 project sensing signals.

In addition, as shown in FIG5 , in one embodiment, the wheel-following protection sensor radar 210 can also be installed (e.g., locked with a threaded structure and repeatedly disassembled and assembled via a screw) at the valve hole 120 of the rim 13 of the wheel 12 , thereby being secured to the valve hole 120 by engaging with the valve's locking member.

Please refer to Figure 1. This figure illustrates further the activation conditions of the present invention's security radar. Specifically, the vehicle condition change security module 20 includes a rim security trigger activation module 24. When the rim security trigger activation module 24 is activated, the signal processing module 22 triggers at least one wheel-follower security radar 210 to perform sensing. Furthermore, the wheel-following defense sensing radar 210 can utilize a commercially available ultrasonic sensing radar. The ultrasonic sensing radar has a sensing range of approximately 20 to 60 centimeters, and the sensing range can be adjusted based on actual usage conditions; that is, the proximity distance at which sensing is triggered and the minimum proximity distance can be adjusted.

In a first embodiment of the rim guard triggering module 24 of the present invention, the rim guard triggering module 24 is activated based on an automatic triggering signal. Specifically, the automatic triggering signal can be a reverse triggering signal, an ignition switch triggering signal, a direction signal, a vehicle speed signal falling below a preset threshold, manual activation by the user, or a wheel speed falling below a preset threshold.

1, in a second embodiment of the wheel rim protection triggering module 24 of the present invention, the wheel rim protection triggering module 24 is activated via the vehicle communication interface 16 (such as CAN) of the vehicle 10. BUS; but not limited thereto) and is informationally connected to the vehicle computer 15 (ECU) of the vehicle 10. The wheel rim defense trigger activation module 24 captures at least one automatic trigger signal from the vehicle 10 through the vehicle computer 15 and the on-board communication interface 16, and transmits the at least one automatic trigger signal to the signal processing module 22. When the signal processing module 22 receives at least one automatic trigger signal, it outputs an activation signal to activate at least one wheel follower defense sensing radar 210 for sensing. Specifically, the at least one automatic trigger signal can be a reverse start trigger signal, an ignition switch start trigger signal, a direction signal, or a vehicle speed signal. More specifically, the signal processing module 22 can compare the vehicle speed signal with a preset vehicle speed value (e.g., below 30 kilometers per hour) to determine when to output the start signal.

Referring to Figures 1 and 6 , a specific embodiment for achieving the third objective of the present invention includes, in addition to the overall technical content of the first embodiment described above, a cooperative defense module 30, which includes an auxiliary lighting device 31. When the vehicle condition change defense module 20 is activated, the auxiliary lighting device 31 is synchronously activated to project light toward the area near at least one wheel 12.

As described above, the auxiliary lighting device 31 shown in Figures 6 and 7 is mounted on at least one rearview mirror 14 of the vehicle 10. The cooperative protection module 30 further includes at least one wheel-assisted protection sensing radar 32. The at least one wheel-assisted protection sensing radar 32 is mounted on at least one rearview mirror 14 of the vehicle 10 (preferably the right rearview mirror) and is used to perform radar sensing of the area near at least one wheel 12.

Please refer to FIG1 , which mainly illustrates the embodiment of the wireless data signal transmission of the present invention. The vehicle condition change protection module 20 further includes a wireless signal transmission module 25 (such as a Bluetooth communication module, a ZigBee communication module, or a WIFI communication module) for connecting at least one radar sensing module 21 with a signal processing module 22. The radar sensing module 21 further includes a signal processing module 22 for providing the radar sensing module 21 with the signal processing module 22. The power supply module 211 (e.g., a button-type battery, removably mounted and assembled with the radar sensor module in a small housing) is used to interpret and process at least one vehicle condition change signal to generate a corresponding control signal. This control signal triggers the defense warning module 23 to output at least one defense warning message, including direction and distance (e.g., represented by the length and frequency of the audio), via audio, voice, or display. The power required by the signal processing module 22, wireless signal transmission module 25, and other modules can be supplied by the power supply module on the vehicle 10.

Please refer to FIG1 and FIG8-11 for a specific operation embodiment of the present invention. When the driver starts the ignition of the vehicle 10 parked in the parking space, first, when the signal processing module 22 receives the automatic trigger signal of the vehicle 10 through the vehicle computer 15 and the vehicle communication interface 16, it outputs a start signal and uses the start signal to start each wheel follower type defense sensor radar 21. 0 for sensing; at this time, each wheel follow-up defense sensing radar 210 begins to sense whether there is a foreign object 1 in the visual blind spot (such as the wheel side area) at a predetermined safety distance on the side of the wheel 12. When one of the wheel follow-up defense sensing radars 210 on the vehicle 10 senses that a foreign object 1 is approaching, one of the wheel follow-up defense sensing radars 210 generates a wheel foreign object approaching change. The signal processing module 22 interprets and processes the signal and outputs a corresponding control signal. The control signal triggers the driving defense warning module 23 to drive the defense warning module 23 to output defense warning information including left and right directions and distance information. Therefore, the driver of the vehicle can know the real-time location of the foreign object 1, thereby reminding the driver to check whether the steering wheel is returned to the center. This prevents the front wheel 12 from swerving to the right and striking the curb 1a on the outside of the sidewalk, as shown in Figures 8-9, or the curb 1b on the outside of the roadside flowerbed, as shown in Figures 8 and 10. It also prevents the front wheel 12 from swerving to the left and striking the curb 1c on the outside of the safety island, as shown in Figure 11. This effectively prevents wheel scratches and other potential financial losses.

Therefore, through the configuration of the above-mentioned specific structure, this new model indeed has the following characteristics:

1. This new model, through its low-obstacle side-obstacle sensing and warning system, can more comprehensively detect obstacles around the vehicle, particularly those located in the vehicle's blind spots. This provides the driver with real-time obstacle warning information, thereby reducing collision risk and preventing financial losses from wheel rim scratches.

2. The radar sensor used in this new model has a compact modular structure that can be easily and conveniently installed on the wheels of a vehicle and can accurately determine the distance and direction of obstacles.

3. This new model does have omnidirectional radar sensing, which improves obstacle detection accuracy.

4. This new model does have a coordinated protection function, projecting light into the area near the wheels, effectively improving parking safety.

Any equivalent implementation based on the content, features, and spirit of the following claims shall be included in the patent scope of this invention.
