Abstract

본 발명의 전기 자동차의 속도 지령방법 및 지령장치는 속도 지령신호를 발생하는 가변저항에 이상이 있을 경우에 이를 경보하면서 전기 자동차의 주행을 정지시키는 것이다.The speed command method and the command apparatus of the electric vehicle of the present invention are to stop the running of the electric vehicle while alarming when there is an error in the variable resistance generating the speed command signal.

본 발명은 액셀레이터 페달에 2개 이상의 가변저항(1)(2)을 설치하여 액셀레이터 페달을 밟음에 따라 가변저항(1)(2)의 값이 가변되면서 출력하는 속도 지령신호가 가변되게 하고, 이 가변되는 속도 지령신호를 파형 정형부(3)(4), 인터페이스부(5) 및 아날로그/디지탈 변환부(6)를 순차적으로 통해 전자제어 유니트부(7)가 입력하여 가변저항(1)(2)이 각기 출력하는 속도 지령신호의 차이값을 검출하며, 검출한 차이값이 미리 설정된 기준레벨 이상일 경우에 가변저항(1)(2)에 이상이 발생한 것으로 판단하고, 전기 자동차의 주행을 정지시키면서 경보부(8)가 경보음을 발생하게 한다.According to the present invention, two or more variable resistors (1) and (2) are provided in the accelerator pedal to allow the speed command signal to be output while the value of the variable resistors (1) and (2) is varied as the accelerator pedal is pressed. The variable speed command signal is inputted by the electronic control unit 7 through the waveform shaping section 3, 4, the interface section 5, and the analog / digital conversion section 6 sequentially. 2) detects the difference value of the speed command signal respectively outputted, and when the detected difference value is equal to or more than the preset reference level, it is determined that an error has occurred in the variable resistor (1) (2), and the driving of the electric vehicle is stopped. While making the alarm unit 8 generate an alarm sound.
