Autonomous driving technology relies on the collaborative efforts of artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems to enable computers to automatically and safely operate motor vehicles without any active human intervention.

[0003] In current autonomous driving technology, primary driving responsibility lies with the vehicle, which monitors various driving conditions and makes appropriate decisions about driving behavior. However, existing autonomous vehicles are typically equipped with warning devices that require the driver to periodically disturb the steering wheel before the device stops signaling. This requires the driver to expend effort constantly disturbing the steering wheel during autonomous driving, undermining the convenience of autonomous driving. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 3 The present invention proposes an automatic steering wheel disturbance device 200.

[0028] The automatic steering wheel disturbance device 200 is used to be installed on the steering wheel 100 of a vehicle. The vehicle includes a warning device for sending a warning signal during automatic driving. When the steering wheel 100 is disturbed by an external force, the warning device stops sending the warning signal. The automatic steering wheel disturbance device 200 includes a mounting shell 210 and a gyroscope sensor 220, a steering wheel disturber 230, and a main control unit 270. The mounting shell 210 is used to be installed on the steering wheel 100. The gyroscope sensor 220 is arranged on the mounting shell 210. The gyroscope sensor 220 is used to detect the warning signal sent by the warning device. When a warning signal is issued, the steering wheel 100 is subjected to an angular velocity disturbance caused by an external force; the steering wheel disturber 230 is arranged on the mounting shell 210, and the steering wheel disturber 230 is used to disturb the steering wheel 100, so that the warning device stops the warning signal; the main control unit 270 is arranged on the mounting shell 210, and is electrically connected to the gyroscope sensor 220 and the steering wheel disturber 230; the main control unit 270 is used to receive the angular velocity signal of the gyroscope sensor 220, and control the power of the steering wheel disturber 230 to disturb the steering wheel 100 according to the angular velocity signal, so that the warning device stops the warning signal.

[0029] Specifically, the vehicle is embedded with an autonomous driving controller, which is used to implement autonomous driving functions. For example, the autonomous driving controller can be used to control the vehicle to enter and exit autonomous driving modes. A gyroscope sensor 220 is one of the key components. Gyroscope sensor 220 is installed under the vehicle's steering wheel 100 to measure the angular velocity signal caused by the driver's action on the steering wheel 100, resulting in changes in the angular velocity of the steering wheel 100. This angular velocity signal is then transmitted to the main control unit 270, which converts the analog signal into a digital signal. The main control unit 270 then controls the power of the steering wheel perturbator 230 based on the angular velocity signal to perturb the steering wheel 100.

[0030] It should be noted that during the autonomous driving process, the warning device in the vehicle will occasionally issue a warning signal, which can be a flashing light or a "beep" sound. The driver can install the automatic steering wheel perturbation device 200 of the present invention on the vehicle's steering wheel 100 and use the gyroscope sensor 220 to measure the angular velocity when the driver externally rotates the steering wheel 100 to stop the warning signal. The angular velocity signal measured by the driver turning the steering wheel 100 is then transmitted to the main control unit 270. The main control unit 270 controls the power of the steering wheel perturbator 230 based on the angular velocity signal to adapt to the external force required to stop the warning signal in different vehicle autonomous driving states, so that the power reaches a level that can stop the warning signal and prevent the steering wheel perturbator 230 from having too little power to stop the warning device from issuing the warning signal. In this way, the main control unit 270 of the automatic steering wheel perturbation device 200 of the present invention can control the steering wheel perturbator 230 to perform perturbation, and the vehicle can automatically stop the warning signal without human operation, making the driving process more convenient and enhancing intelligence.

[0031] Furthermore, the steering wheel disturber 230 uses a micro-vibration motor. The micro-vibration motor achieves a vibration effect through the centrifugal force generated by the motor. This vibration can disturb the steering wheel 100, causing the warning device to automatically stop the warning signal without manual operation, thereby improving convenience.

[0032] See also Figure 3 Furthermore, a hook portion 250 is provided on the mounting shell 210, and the hook portion 250 is used to hook the mounting shell 210 onto the steering wheel 100. By using the hook portion 250 on the steering wheel 100, the installation stability of the steering wheel automatic perturbation device 200 is ensured, while it is necessary to ensure that the vibration of the micro-vibration motor inside the steering wheel automatic perturbation device 200 can be transmitted to the steering wheel 100. The hook portion 250 adopts an elastic mounting structure to reduce the damage of the hook portion 250 to the steering wheel 100. Installing the mounting shell 210 on the steering wheel 100 by means of the hook portion 250 is a conventional prior art and will not be elaborated on here. Of course, other methods can also be used to fix the steering wheel automatic perturbation device 200 to the steering wheel 100, such as: gluing, bundling or sleeve connection.

[0033] See also Figure 2Furthermore, the mounting housing 210 is provided with a measurement button 241 and a start button 242. The measurement button 241 controls the measurement of the gyroscope sensor 220 via the main control unit 270, and the start button 242 controls the activation of the micro-vibration motor via the main control unit 270. After the driver installs the automatic steering wheel disturbance device 200 on the vehicle's steering wheel 100, he presses the measurement button 241 to measure the angular velocity of the steering wheel 100 when the driver externally turns the steering wheel 100 to stop the warning signal via the gyroscope sensor 220. The angular velocity signal measured when the driver turns the steering wheel 100 is then transmitted to the main control unit 270. The driver presses the measurement button 241 again to end the measurement. Afterwards, the driver presses the start button 242, and the main control unit 270 subsequently controls the vibration of the micro-vibration motor based on the angular velocity signal. The vibration of the micro-vibration motor controlled by the main control unit 270 can be continuous or intermittent, as long as the vehicle can automatically stop the warning signal.

[0034] See also Figure 2 Furthermore, the automatic steering wheel perturbation device 200 also includes a power supply device 260, which is electrically connected to the gyro sensor 220, the micro-vibration motor, and the main control unit 270. The power supply device 260 is used to supply power to the gyro sensor 220, the micro-vibration motor, and the main control unit 270 to ensure the power output of the automatic steering wheel perturbation device 200.

[0035] The embodiment of the present disclosure further provides a vehicle, comprising the aforementioned automatic steering wheel disturbance device 200. Since the aforementioned automatic steering wheel disturbance device 200 has been redundantly described in the above embodiment, it will not be described in detail here.

[0036] Furthermore, the automatic steering wheel perturbation device 200 is provided in or on the steering wheel 100. It can be installed inside the steering wheel 100, or on the outside of the steering wheel 100, or the automatic steering wheel perturbation device 200 can be detachably mounted on the steering wheel 100.

[0037] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
