Abstract

The present invention relates to a steering wheel cover for preventing drowsy driving that determines whether drowsy driving is occurring through the driver's passive behavior and generates a low frequency to the driver when drowsy driving is determined, and a method of operation using the same. The steering wheel cover is mounted on the steering wheel of a vehicle to prevent drowsy driving by the driver and comprises: a low frequency generating unit coupled to the steering wheel cover to generate a low frequency; a speaker coupled to the steering wheel cover to output an alarm sound; a switch that controls the operation of the low frequency generating unit and the speaker; a control unit that determines the operation of the low frequency generating unit, the speaker, and the switch; and a power supply unit that supplies power to the control unit. The switch further comprises a first switch and a second switch.

Description

Handle Cover for Preventing Drowsy Driving and Functioning Method for the Same The present invention relates to a steering wheel cover for preventing drowsy driving and a method of operation using the same. More specifically, it relates to a steering wheel cover for preventing drowsy driving that determines whether drowsy driving is occurring through the driver's passive actions and generates a low frequency to the driver when drowsy driving is determined, and a method of operation using the same. Traffic accidents are caused by various factors, such as drunk driving, inattention, speeding, and drowsy driving. While the best way to prevent such accidents is for drivers to concentrate on driving and drive carefully, accidents caused by drowsy driving are difficult to prevent while driving because they occur due to drowsiness that can suddenly strike. To prevent drowsy driving accidents, steering wheel grips with protrusions are recently being used. These grips are attached to the steering wheel to apply impact to the driver's hands, helping to wake them up. Additionally, sensors based on the driver's biometric signals, such as eye movements, heart rate, and pressure, are used to determine if the driver is drowsy; if drowsiness is detected, a warning signal is output to the driver via speakers or other means. As such, automated systems utilizing sensors and AI can be affected by the driver's physical condition or external environment, which may lead to malfunctions, and their operation can incur high costs. Therefore, there is a need to develop a drowsy driving prevention system that allows the driver to activate the system when necessary to reduce malfunctions and is not limited by vehicle type. FIG. 1 is a configuration diagram according to an embodiment of the present invention. FIG. 2 is a drawing showing a handle equipped with a handle cover according to an embodiment of the present invention. FIG. 3 is a drawing showing a handle cover including a connector according to an embodiment of the present invention. FIG. 4 is a drawing showing a handle cover including a charging part according to an embodiment of the present invention. FIG. 5 is a flowchart showing a method of operating a handle cover according to an embodiment of the present invention. Throughout this specification, terms such as “unit,” “device,” and “system” refer to a unit that processes an operation comprising a combination of one or more functions, and may be implemented in hardware, software, or a combination of hardware and software. Terms such as “part,” “device,” and “system” as used in this specification may be treated as equivalent to computer-related entities, namely hardware, a combination of hardware and software, software, or software at runtime. Additionally, the application program executed in the present invention may be configured in “part” units and may be recorded in a single physical memory in a form that allows reading, writing, and erasing, or may be recorded distributed across two or more memories or recording media. Hereinafter, the present invention will be described with reference to the attached drawings. FIG. 1 is a configuration diagram according to an embodiment of the present invention, and FIG. 2 is a diagram showing a handle equipped with a handle cover according to an embodiment of the present invention. Referring to the drawings, the handle cover (10) may be configured to include a low-frequency generator (100) that generates a low frequency to the driver, a speaker (200) that outputs an alarm sound, a switch (300) that controls the operation of the low-frequency generator (100) and the speaker (200), a control unit (400) that determines the operation of the low-frequency generator (100), the speaker (200), and the switch (300), and a power supply unit (500) that supplies power to the control unit (400) and supplies power to enable the low-frequency generator (100), the speaker (200), and the switch (300) to operate. The low frequency generator (100) generates a low frequency to drive away drowsiness in the driver holding the low frequency generator (100). The low frequency generator (100) is coupled to the steering wheel cover (10) and can be installed symmetrically on both sides based on a vertical line crossing the center of the steering wheel cover (10). This allows the driver to hold the steering wheel at the 9 o'clock and 3 o'clock direction, the 10 o'clock and 2 o'clock direction, or the 8 o'clock and 4 o'clock direction relative to the front of the steering wheel when holding it normally, and thus the low frequency generator (100) can be installed based on this. Additionally, the low frequency generator (100) may be installed only on the front or side of the handle cover (10), or may be installed including both the front and side. The low frequency generator (100) may be formed in a flat plate shape without curvature, and a plurality of conical protrusions having pointed or rounded ends are formed t
