Description

Driving safety management device for personal mobility devices The present invention relates to a driving safety management device for personal mobility devices, and more specifically, to a driving safety management device applicable to electric scooters, electric wheelchairs, electric bicycles, and electric kickboards. In general, accidents involving personal mobility devices (PMs) are increasing every year due to their proliferation. Despite the enactment of relevant regulations over the five-year period from 2017 to 2021, accidents involving personal mobility devices reportedly increased by an annual average of 96.2% (according to the Korea Road Traffic Authority). While various systems (driving assistance systems) that aid in safe driving have been developed and applied to automobiles, there has been a limitation in that they are difficult to apply to personal mobility devices, which are relatively inexpensive and lack the space to accommodate various systems. Registered Patent No. 10-2681949 (Smart Helmet System for Personal Mobility, registered on July 2, 2024), etc., describes a smart helmet that is linked with personal mobility and is equipped with sensors and radar for the safety of the operator. However, the helmet-mounted method has limitations, such as time constraints in power supply and increased weight due to the mounting of various sensors, power units, and batteries, which can cause discomfort when worn and strain the neck. Furthermore, there is a concern about head injury caused by devices mounted on the helmet in the event of an accident; this implies that while a helmet is equipment designed to protect the driver's head during an accident, its protective effect may be reduced by these added devices compared to wearing a helmet alone. Therefore, the market requires the development of driving safety management devices suitable for personal mobility devices that can extend usage time and prevent greater damage in the event of an accident. FIG. 1 is a block diagram of a driving safety management device for a personal mobility device according to a preferred embodiment of the present invention. Figure 2 is a detailed block diagram of the safety controller in Figure 1. Figure 3 is a flowchart of data processing performed in the control unit (310) of the safety controller (300). FIG. 4 is a processing flowchart of a control unit (310) for distinguishing between people and objects in the present invention. To fully understand the structure and effects of the present invention, preferred embodiments of the present invention are described with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms and various modifications can be made. The description of the embodiments is provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. In the attached drawings, components are depicted enlarged from their actual size for convenience of explanation, and the proportions of each component may be exaggerated or reduced. Terms such as 'first' and 'second' may be used to describe various components, but said components should not be limited by said terms. These terms may be used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, 'first component' may be named 'second component,' and similarly, 'second component' may be named 'first component.' Furthermore, singular expressions include plural expressions unless the context clearly indicates otherwise. Unless otherwise defined, terms used in the embodiments of the present invention may be interpreted in the sense commonly known to those skilled in the art. Hereinafter, a driving safety management device for a personal mobility device according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of a driving safety management device of a personal mobility device according to a preferred embodiment of the present invention, and FIG. 2 is a detailed block diagram of a safety controller in FIG. 1. Referring to FIG. 1 and FIG. 2 respectively, the present invention may include an optical sensor (100) installed in a personal mobility device to acquire a front image, a radar sensor (200) for detecting a person by checking biological signals such as breathing, and a safety controller (300) that checks the detection results of the optical sensor (100) and the radar sensor (200), analyzes the risk level, cuts off the power of the battery (500) supplied to the motor (400) of the personal mobility device in a dangerous situation, and provides the risk level analysis result and image to a user terminal (600). Hereinafter, the configuration and operation of the driving stability management device of the personal m
