퍼스널 모빌러티의 운전자보호장치{Driver protection device of personal mobility} Driver protection device of personal mobility

본 발명은 퍼스널 모빌러티의 사고를 방지하거나 사고 발생 시 운전자를 보호하기 위한 퍼스널 모빌러티의 운전자 보호장치로서, 퍼스널 모빌러티가 높은 속도로 주행 중에 충돌 사고가 발생되면 운전자 및 보행자가 크게 다칠 수 있으므로, 이를 방지하기 위해 운전자와 보행자에게 충돌 사고를 경고하거나, 충돌 사고가 발생되면 에어백을 전개시켜 운전자와 보행자를 보호하는 퍼스널 모빌러티의 운전자 보호장치에 관한 것이다.The present invention is a personal mobility driver protection device for preventing personal mobility accidents or protecting drivers in the event of an accident.If a collision accident occurs while driving at a high speed of personal mobility, drivers and pedestrians may be greatly injured. In order to prevent this, it relates to a driver protection device of personal mobility that warns a driver and a pedestrian of a collision accident, or deploys an airbag when a collision occurs to protect the driver and pedestrian.

퍼스널 모빌러티는 전기를 동력원으로 사용하는 개인용 이동수단을 총칭하는 것으로서, 전기자전거, 전동킥보드, 전동휠, 전동스쿠터, 투휠, 싱글휠 등이 해당되지만, 본 발명에서는 프레임(골격)과 핸들부를 포함하는 전기자전거, 전동킥보드 및 전동스쿠터, 세그웨이형의 투휠로 한정한다.Personal mobility is a generic term for personal mobility that uses electricity as a power source, and includes electric bicycles, electric kickboards, electric wheels, electric scooters, two wheels, and single wheels, but in the present invention, the frame (skeleton) and handle are included. It is limited to electric bicycles, electric kickboards and electric scooters, and two-wheeled segway types.

퍼스널 모빌러티는 내연기관이 아닌 전기로 구동되는 친환경 교통수단에 대한 필요성이 높아지는 상황에서 1인 가구가 증가하고, 고령화 등에 따른 신교통 수단에 대한 필요성이 증대되면서 급격하게 수요가 증가하고 있다. 국내에서 퍼스널 모빌리티를 이용하는 인구는 2014년 수백여명에서 2017년을 기준으로 7만 5천명을 넘어선 것으로 추정되며, 2022년에는 20만대 수준으로 꾸준히 확대될 것으로 예상된다.Personal mobility is rapidly increasing in demand as the number of single-person households increases in a situation where the need for eco-friendly transportation means powered by electricity rather than internal combustion engines increases, and the need for new transportation means increases due to aging. The number of people using personal mobility in Korea is estimated to have exceeded 75,000 in 2017 from hundreds of people in 2014, and is expected to steadily expand to the level of 200,000 in 2022.

하지만, 퍼스널 모빌러티의 보급이 크게 확대되면서 그에 따른 사고도 급격히 늘고 있어, 최근 3년(2016∼2018년)간 대형보험사에 접수된 전동킥보드와 차량 간 교통사고는 총 488건으로 2016년 49건에서 2017년 181건, 2018년 258건으로 지속 증가하고 있고, 향후 급격하게 늘어날 가능성이 높은 상황이다.However, as the spread of personal mobility is greatly expanded, the resulting accidents are also rapidly increasing. In the last 3 years (2016-2018), traffic accidents between electric scooters and vehicles received by large insurance companies totaled 488 cases, from 49 cases in 2016. It is increasing continuously to 181 in 2017 and 258 in 2018, and there is a high possibility that it will increase rapidly in the future.

전기로 구동되지는 않지만 그동안 많은 사람들이 이용한 자전거는 개인용 교통수단으로서 많이 보급되었고, 자전거 전용도로가 전국에 개통되면서 그 이용 또한 많이 늘면서 사고를 방지하기 위한 기술들도 함께 개발되었다.Although not powered by electricity, bicycles that many people have used so far have been widely distributed as a means of personal transportation. As bicycle roads were opened nationwide, the use of bicycles was also increased, and technologies to prevent accidents were also developed.

도 5는 전기자전거 운전자 보호장치의 블록 구성도이고, 도 6은 본 발명의 일 실시예로서 전기자전거에 설치되는 운전자 보호장치의 주요 구성도이다. 5 is a block diagram of an electric bicycle driver protection device, and FIG. 6 is a main configuration diagram of a driver protection device installed in an electric bicycle as an embodiment of the present invention.

본 일 실시예의 운전자 보호장치의 주요 구성에 대해 살펴보면, 전기자전거는 전기자전거의 골격을 이루는 프레임(1), 프레임의 중앙에 설치되어 운전자가 탑승하는 탑승부(2), 프레임의 전방에 설치되어 앞바퀴의 방향을 조정하는 핸들부(3)로 구성된다.Looking at the main configuration of the driver protection device of this embodiment, the electric bicycle is a frame 1 that forms the skeleton of the electric bicycle, a boarding part 2 installed in the center of the frame, and a boarding part 2 on which the driver rides, and is installed in front of the frame. It consists of a handle part (3) for adjusting the direction of the front wheel.

그리고, 전기자전거에 설치되는 운전자 보호장치는 핸들부의 아래쪽에서 핸들부를 지지하는 프레임에 설치되는 정면 에어백 모듈, 탑승부의 아래쪽에서 탑승부를 지지하는 프레임의 좌우 측면에 설치되는 측면 에어백 모듈, 보행자 또는 장애물을 감지하는 센서부, 보행자의 접근을 알려주는 경고부, 운전자 보호장치의 구성요소들을 제어하는 제어부로 구성된다.In addition, the driver protection device installed in the electric bicycle is a front airbag module installed on the frame supporting the handle part from the bottom of the handle part, side airbag modules installed on the left and right sides of the frame supporting the boarding part under the boarding part, and pedestrians or obstacles. It consists of a sensor unit that detects, a warning unit that notifies the approach of a pedestrian, and a control unit that controls the components of the driver's protection device.

정면 에어백 모듈 및 측면 에어백 모듈은 케이스 내에 에어백과 인플레이터(가스발생기)가 설치되며, 센서부가 충돌사고 발생을 탐지하면 제어부의 명령에 의해 인플레이터에서 에어백을 팽창시키는 가스가 발생하여 에어백을 순간적으로 팽창시키도록 작동한다. The front airbag module and the side airbag module have an airbag and an inflator (gas generator) installed in the case, and when the sensor detects a collision accident, gas that inflates the airbag is generated from the inflator by the command of the control unit to inflate the airbag momentarily. So it works.

센서부(10)는 프레임의 정면에 설치되어 장애물 또는 보행자를 감지하여 제어부로 그 정보를 전송한다. 센서부의 설치 위치는 프레임의 정면 뿐 아니라 사고 발생이 예측되는 방향을 향하여 임의로 변경할 수 있다.The sensor unit 10 is installed in front of the frame to detect an obstacle or a pedestrian and transmits the information to the control unit. The installation position of the sensor unit can be arbitrarily changed not only toward the front of the frame but also toward the direction in which an accident is expected.

센서부는 초음파 센서, 레이더, 레이저 센서와 같은 거리 측정 센서, 속도센서, 충돌 센서, 자이로 센서 등 에어백을 전개시키기 위해 차량 주행 상황과 사고 발생 가능성 및 충돌 발생 여부를 측정할 수 있는 센서면 어떤 센서라도 사용할 수 있다.The sensor unit is a sensor that can measure the driving situation of the vehicle, the possibility of an accident, and the occurrence of a collision in order to deploy an airbag such as an ultrasonic sensor, a radar, and a distance measuring sensor such as a laser sensor, a speed sensor, a collision sensor, and a gyro sensor. Can be used.

거리 측정 센서는 초음파, 전자기파, 레이저를 물체에 송신하여 되돌아오는 반사파로부터 그 물체와의 거리를 측정하여 제어부로 송신한다.The distance measurement sensor transmits ultrasonic waves, electromagnetic waves, and lasers to the object, measures the distance to the object from the reflected wave and transmits it to the control unit.

속도 센서는 전기자전거의 속도를 검출하는 센서로서, 많이 사용되는 것에 초음파, 레이저, 마이크로파 등의 도플러 효과를 이용한 센서가 있다A speed sensor is a sensor that detects the speed of an electric bicycle, and there are sensors that use Doppler effects such as ultrasonic waves, lasers, and microwaves.

충돌 센서는 전기자전거가 충돌할 때 가속도가 급격히 줄어드는 것을 측정하기 위하여 가속도 센서가 사용된다.The collision sensor is an acceleration sensor to measure that the acceleration decreases rapidly when the electric bicycle collides.

자이로 센서는 자이로스코프에 의해 각속도를 측정하여 전기자전거의 각도를 측정한다.The gyro sensor measures the angle of the electric bicycle by measuring the angular velocity by a gyroscope.

제어부는 센서부의 정보로부터 사고 발생 가능성 있는지 판단하여, 사고가 예측되면 경보부를 통해 운전자 또는 보행자에게 경고를 하고, 충돌 사고 발생 가능성이 높거나 충돌사고가 발생한 것으로 판단되면 정면 에어백 모듈 또는 측면 에어백 모듈을 작동시킨다.The control unit determines whether there is a possibility of an accident from the information from the sensor unit, and if an accident is predicted, it warns the driver or pedestrian through the alarm unit, and when it is determined that the possibility of a collision accident is high or a collision accident has occurred, the front airbag module or the side airbag module is installed. It works.

구체적으로 사고가 예측되는 상황을 설명하면, 운전자가 전기자전거를 사고 발생 가능성이 높은 제1 임계속도 이상으로 운전하는 상황에서 주변 장애물과의 거리가 제1 임계거리 이하인 경우 경고부를 통해 진동, 소리 또는 빛으로 보행자와 운전자에게 충돌 사고를 경고하고, 퍼스널 모빌러티를 구동시키는 모터의 회전속도 제어하여 퍼스널 모빌러티의 속도를 낮추어 충돌을 방지하도록 한다. 이때 제1 임계속도 및 제1 임계거리는 통상 20Km/h로와 3m로 하며, 이들 임계수치는 도로, 날씨, 주행 환경을 고려하여 변경할 수 있다.Specifically, when an accident is predicted, when the driver drives the electric bicycle at a first critical speed or higher with a high probability of an accident, when the distance to the surrounding obstacle is less than the first critical distance, vibration, sound, or The light warns pedestrians and drivers of a collision accident, and reduces the speed of personal mobility by controlling the rotation speed of the motor that drives personal mobility to prevent a collision. At this time, the first critical speed and the first critical distance are usually 20Km/h and 3m, and these critical values can be changed in consideration of road, weather, and driving environment.

다음으로, 충돌사고 발생이 높은 상황과 충돌사고가 발생하는 상황은 장애물 또는 보행자와 충돌이 발생하거나, 퍼스널 모빌러티의 속도가 제1 임계속도보다 높은 제2 임계속도, 가령 30Km/h 이상이면서, 측정된 거리가 제1 임계거리보다 짧은 제2 임계 거리, 가령 2m 이하로 충돌 발생이 예측되면 정면 에어백 모듈이 팽창되고, 퍼스널 모빌러티의 기울기가 지면을 기준으로 임계각도 가령 30도 이하이면 해당 방향의 측면에어백을 팽창시켜 보행자 또는 운전자를 보호하도록 한다. 물론, 제2 임계속도와 제2 임계거리 및 임계각도도 사용자가 도로, 날씨, 주행 환경을 고려하여 변경할 수 있다.Next, the situation in which the collision is high and the situation where the collision occurs is when a collision occurs with an obstacle or a pedestrian, or the speed of the personal mobility is a second critical speed higher than the first critical speed, for example, 30Km/h or more, If the measured distance is a second critical distance shorter than the first critical distance, for example, less than 2m, when a collision is predicted, the front airbag module is inflated, and if the inclination of personal mobility is less than a critical angle, such as 30 degrees from the ground, the corresponding direction Inflate the side airbags to protect pedestrians or drivers. Of course, the second critical speed, the second critical distance, and the critical angle can also be changed by the user in consideration of road, weather, and driving environment.

또한, 운전자가 스마트폰을 거치대에 장착하여 네비게이션 등과 같은 앱을 실행하거나 운전자가 스마트기기의 다른 앱을 실행하고 있을 때, 퍼스널 모빌러티의 속도가 제1 임계속도 이상이면서, 측정된 거리가 제1 임계 거리 이하인 경우, 다른 앱은 종료되고 안전운행 앱이 스마트기기 화면에 표시되면서 충돌사고를 경고하고, 퍼스널 모빌러티를 구동시키는 모터의 회전속도 제어하여 퍼스널 모빌러티의 속도를 낮추어 충돌사고를 방지할 수 있다.In addition, when the driver installs the smartphone on the cradle to run an app such as navigation or the driver is running another app on the smart device, the speed of personal mobility is greater than or equal to the first threshold speed, and the measured distance is the first. If the distance is less than the critical distance, other apps are terminated and the safe driving app is displayed on the screen of the smart device to warn of a crash accident, and to reduce the speed of personal mobility by controlling the rotation speed of the motor driving personal mobility to prevent a crash. I can.

이때, 안전운행 앱의 충돌사고 경고는 ‘문자’또는 ‘색상’또는 ‘소리’의 조합을 통해 운전자가 충돌사고가 발생할 수 있음을 쉽게 인지할 수 있도록 할 수 있다.At this time, the collision accident warning of the safe driving app can enable the driver to easily recognize that a collision may occur through a combination of'text' or'color' or'sound'.
