Abstract

본 발명은 전기 자동차용 브레이크 시스템 이상 경고 및 안전장치에 관한 것으로서, 종래의 전기자동차에 설치된 브레이크 시스템은 배큠계통의 이상발생이나 부스터 장치의 이상발생에 대하여 경고 및 응급조치를 하기 위한 장치가 설치되지 않아 사용상 위험성을 내포하게 되는 문제점이 있었다. 배큠펌프 및 모터(10)에는 전압측정용 센서(미도시)가 설치되고, 부스터(20)장치에서는 압력을 센싱하기 위한 압력센서(60)가 설치되어, 상기 센싱된 각각의 신호(70)가 비교부(30)에 입력되게 하되, 상기 비교부(30)는 기준값을 미리 설정하여 센싱된 신호와 비교하게 되며, 이상 상태를 판단하게 되면 디스플레이부(40)를 통해 경보음 부저(41)와 램프(42)를 작동하게 하고, 컨트롤러(50)에 이상 사태 발생 신호를 인가할 수 있도록 구성된다. 따라서 본 발명을 이용한 전기자동차는 브레이크 시스템에 발생되는 각종 이상 상태를 즉각 경고할 수 있게 되며, 컨트롤러를 이용하여 차량의 전장품을 제어하며 비상 및 응급 조치할 수 있게 하여 운전자에게 심리적안정을 주고 각종사고를 미연에 방지할 수 있는 효과가 있다.The present invention relates to a brake system failure warning and safety device for an electric vehicle, and a brake system installed in a conventional electric vehicle is not provided with a device for warning and emergency measures against abnormality of the distribution system or abnormality of the booster device. There was a problem that contains a risk of use. The vacuum pump and the motor 10 are provided with a voltage measuring sensor (not shown), and in the booster 20 device, a pressure sensor 60 for sensing pressure is installed, and each of the sensed signals 70 is provided. The comparator 30 is input to the comparator 30, but the comparator 30 compares the detected signal by setting a reference value in advance, and when an abnormal state is determined, the alarm sound buzzer 41 is communicated with the display 40. It is comprised so that the lamp 42 may be operated and the abnormality occurrence signal may be applied to the controller 50. Therefore, the electric vehicle using the present invention can immediately warn of various abnormal conditions occurring in the brake system, control the electrical equipment of the vehicle by using the controller and enable emergency and emergency measures to give the driver psychological stability and various accidents. There is an effect that can be prevented in advance.

Claims

In an electric vehicle brake system warning and safety device, a voltage sensor is installed in the back pump and the motor, and a pressure sensor is installed in the booster so that signals from the sensor are input to the comparator, respectively, wherein the comparator is previously By comparing the signals input to the set reference value, when the diagnosis of the abnormal condition, the warning buzzer and lamp operation, and configured to apply the abnormal signal to the controller abnormality warning and electric vehicle, characterized in that safety device.
