Abstract

PURPOSE: A warning device of over-vibration for a vehicle alarms if the vehicle is over-speeding when a frequency of vibration is above a given frequency. CONSTITUTION: A warning device of an over-vibration for the vehicle comprises a speed sensor (120) for detecting a vehicle speed, a vibration sensor(110) for detecting a vibration of the vehicle on running state, a microcomputer(130) and an alarm output unit(140). The microcomputer(130) receives an emergency signal from the speed and vibration sensor(110, 120) and memories an appropriate frequency of vibration depending on the vehicle speed. The alarm output unit(140) outputs an alarm message when the frequency of vibration is higher than the frequency of vehicle speed. Thus, the vehicle avoids over-speeding on over-vibration state, thereby protecting a vehicle accident.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 대하여 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 실시예에 따른 차량의 과잉진동 경보장치의 개략적인 블럭구성도로서, 진동센서(110), 차속센서(120), 마이컴(130) 및 카스테레오(140 )로 구성 된다.1 is a schematic block diagram of an over-vibration warning device for a vehicle according to a preferred embodiment of the present invention, which includes a vibration sensor 110, a vehicle speed sensor 120, a microcomputer 130, and a car stereo 140.

도 1에 있어서, 진동센서(110)는 차체의 진동을 감지하여 그에 상응하는 진동주파수를 마이컴(130)으로 제공하고, 차속센서(120)는 차량의 현재속도를 감지하여 마이컴(130)으로 제공한다.In FIG. 1, the vibration sensor 110 detects a vibration of a vehicle body and provides a vibration frequency corresponding thereto to the microcomputer 130, and the vehicle speed sensor 120 detects a current speed of the vehicle and provides the microcomputer 130 to the microcomputer 130. do.

그리고, 마이컴(130)은 진동센서(110)로부터 제공되는 진동주파수가 기설정된 소정주파수(예를 들면, 60Hz)를 초과하는 경우, 차속센서(120)를 통해 감지되는 차량의 현재속도를 체크하여, 기설정된 소정속도(예를 들면, 1OOKm/h)를 초과하면 내부에 저장된 경보메세지를 출력하기 위한 제어신호를 발생한다.In addition, when the vibration frequency provided from the vibration sensor 110 exceeds a predetermined frequency (eg, 60 Hz), the microcomputer 130 checks the current speed of the vehicle detected through the vehicle speed sensor 120. When a predetermined speed (eg, 1OOKm / h) is exceeded, a control signal for outputting an alarm message stored therein is generated.

또한, 카스테레오(140)는 마이컴(130)으로부터의 경보 제어신호에 의해 경보메세지(예를 들면, "차체의 과잉진동으로 인해 1OOKm/h 를 초과하지 못합니다."를 출력한다.In addition, the car stereo 140 outputs an alarm message (for example, "not exceeding 1OOKm / h due to excessive vibration of the vehicle body") by the alarm control signal from the microcomputer 130.

상기한 바와 같이 구성된 본 발명에 따른 차량의 과잉진동 경보장치의 동작과정에 대하여 도 1 내지 도 2를 참조하여 보다 상세하게 설명하기로 한다.An operation process of the excessive vibration warning apparatus for a vehicle according to the present invention configured as described above will be described in more detail with reference to FIGS. 1 to 2.

먼저, 차량의 주행중에 차체로부터 전달되는 진동이 진동센서(110)를 통해 감지되어 그에 상응하는 진동주파수가 마이컴(130)으로 제공되고(스텝 210), 마이컴(130)은 진동센서(110)로부터 제공되는 진동주파수와 기설정된 소정주파수(예를 들면, 60Hz)를 비교한다(스텝 212).First, the vibration transmitted from the vehicle body during the driving of the vehicle is sensed through the vibration sensor 110 and the corresponding vibration frequency is provided to the microcomputer 130 (step 210), the microcomputer 130 from the vibration sensor 110 The provided vibration frequency is compared with a predetermined predetermined frequency (for example, 60 Hz) (step 212).

상기 스텝(220)에서의 비교결과, 진동센서(110)를 통해 감지된 차량의 진동주파수가 기설정된 소징주파수(60Hz)를 초과하는 경우, 마이컴(130)은 차속센서(120)로부터 제공되는 차량의 현재속도를 감지하여(스텝 214), 차속센서(120)를 통해 감지된 차량의 헌재속도와 기설정된 소정속도(예를 들면, 10OKm/h)를 비교한다(스텝 216).As a result of the comparison in step 220, when the vibration frequency of the vehicle detected by the vibration sensor 110 exceeds a preset sowing frequency (60 Hz), the microcomputer 130 is provided from the vehicle speed sensor 120. The current speed of the vehicle is sensed (step 214), and the current speed of the vehicle detected by the vehicle speed sensor 120 is compared with a predetermined predetermined speed (for example, 10 OKm / h) (step 216).

상기 스텝(216)에서의 비교결과, 차속센서(120)를 통해 감지된 차량의 현재속도가 기설정된 소정속도(10OKm/h)를 초과하면 마이컴(130)은 이를 경보하기 위한 제어신호를 발생하고, 마이컴(130)으로부터의 경보 제어신호에 의해 카스테레오(140)를 통해 경보메세지(예를 들면, "차체의 과잉진동으로 인해 1OOKm/h 를 초과하지 못합니다.")가 출력된다.As a result of the comparison in step 216, when the current speed of the vehicle detected by the vehicle speed sensor 120 exceeds a preset predetermined speed (10 OKm / h), the microcomputer 130 generates a control signal for alarming this. In response to the alarm control signal from the microcomputer 130, an alarm message (for example, "1OOKm / h cannot be exceeded due to excessive vibration of the vehicle body") is output through the stereo stereo 140.

상술한 바와 같이, 진동센서(110)를 통해 감지된 차체의 진동주파수가 기설정된 소정주파수를 초과하는 상태에서, 차속센서(120)를 통해 감지된 차량의 현재속도가 기설정된 소정속도를 초과하게 되면, 마이컴(130)으로부터의 경보 제어신호에 의해 카스테레오(140)를 통해 경보메세지가 출력된다.As described above, in a state in which the vibration frequency of the vehicle body detected by the vibration sensor 110 exceeds a predetermined frequency, the current speed of the vehicle detected by the vehicle speed sensor 120 exceeds the predetermined speed. In response to the alarm control signal from the microcomputer 130, the alarm message is output through the stereo stereo 140.

한편, 본 발명의 실시예에서는 차체의 과잉진동상태에서 차량이 과속되는 경우, 카스테레오를 통해 경보메세지를 출력하는 것으로 하여 설명하였으나, 이 기술분야의 숙련자는 본 발명이 이에 한정되는 것이 아니라, 브레이크 액츄에이터를 적절히 조절함으로써, 기설정된 소정속도를 초과하지 않도록 브레이크를 작동할 수도 있다는 것을 쉽게 알 수 있을 것이다.Meanwhile, in the exemplary embodiment of the present invention, when the vehicle is speeded in an excessive vibration state of the vehicle body, it is described as outputting an alarm message through a stereo, but those skilled in the art are not limited thereto, and the brake actuator is not limited thereto. It will be readily appreciated that by appropriately adjusting, the brake may be operated so as not to exceed a predetermined predetermined speed.

따라서, 본 발명을 이용하면, 차체의 과잉진동상태에서 차량의 과속으로 인한 교통사고를 미연에 방지할 수 있는 효과가 있다.Therefore, using the present invention, there is an effect that can prevent in advance the traffic accident due to the speed of the vehicle in the excessive vibration state of the vehicle body.
