Abstract

본 발명은 차량의 차선변경 가이드 시스템에 관한 것으로써 주행도중 차선변경을 하려고 할 때 백미러를 통하여 변경하고자 하는 차선에 위치한 차량의 간격을 확인후 차선을 변경할 때 사물이 사이드미러에 보이는 것보다 가까이 있기 때문에 초보운전자나 깊은 주의를 기울이지 않을 경우에는 사고의 위험성이 큰 문제점이있었으나, 다음과 같이 차선변경을 하려고 하는 방향의 앞뒤차량의 위치와 거리를 감지하여 전기적 신호로 변환하여 출력하는 초음파센서(10)와, 현 차량의 속도를 감지하여 전기적 신호를 변환하여 출력하는 차속센서(20)와, 초음파센서(10)와 차속센서(20)에서 입력받은 신호를 연산하여 전후차량의 속도와 간격을 산출하고 현 차량의 속도와 위치에서 차선변경이 가능한지를 추론하는 제어부(30)와, 상기 제어부 (30)에서 추론된 결과를 표시하여 주는 표시부(60)와, 제어부(30)에 전원을 공급하는 작동스위치(SW)를 포함 구성되어 차선변경가능여부를 알려 주어 수월하게 차선을 변경할 수 있도록 하는 차량의 차선변경 가이드 시스템을 제공한다.The present invention relates to a lane change guide system of a vehicle. When a lane is changed during driving, an object is closer to the side mirror when the lane is changed after checking the distance between vehicles located in the lane to be changed through the rearview mirror. Therefore, if you are a novice driver or do not pay deep attention, there is a big risk of an accident, but the ultrasonic sensor that detects the position and distance of the front and rear vehicles in the direction to change lanes and converts it into an electrical signal and outputs it. ), And calculate the speed and interval of the front and rear vehicle by calculating the vehicle speed sensor 20 to detect the speed of the current vehicle and converts the electrical signal and outputs the signal received from the ultrasonic sensor 10 and the vehicle speed sensor 20. And the controller 30 inferring whether the lane change is possible at the speed and the position of the current vehicle, and the result inferred by the controller 30. A lane change guide system for a vehicle, which includes a display unit 60 for displaying a section and an operation switch (SW) for supplying power to the control unit 30 to indicate whether lane change is possible and to easily change lanes. To provide.
