Abstract

본 발명의 목적은 축전지 소모 상태를 고려한 듀티비를 설정해서 안정된 주행감이 얻어지는 주행 장치와 소모 상태를 불구하고 안정된 제동력이 얻어지는 희생 브레이크와, 또한 복수의 동작 정이 레벨을 두고 첫번의 정지 동작을 억제할 수 있는 확실한 알림이 가능한 보호 장치를 제공하는 것이다.
본 발명의 구성은 제1발명이 모터를 초퍼 제어에 의해 구동하는 제어 방법을 사용한 전기자동차이며, 축전지의 소모 상태에 따라서 초퍼 듀티를 보상함으로써 동일 주행 감각을 얻게 해서 쾌적화시키고, 제2발명이 회생전력을 모터 구동 회로에 의해 소비하는 것에 의해 축전지의 소모 상태에 불구하고 회생 브레이크 장치의 동작을 안정화해서 성능을 향상화시키고, 제3발명이 기기의 동작 상황을 파악하여 이상을 경고하고 정지시키는 보호 장치에 있어서 정지 동작을 2단계로 하고 이 첫번의 정지 동작을 억제하는 취소 스위치를 두고 상황에 의해 보호 장치의 강제적인 정지 동작을 억제하는 것이다.
