The invention discloses an automobile emergency power-off system and an automobile with the same. The automobile emergency power-off system comprises a self-locking electromagnetic switch, a storage battery, an ignition switch, a rocker switch and an engine ECU, wherein the storage battery is connected with the self-locking electromagnetic switch, the self-locking electromagnetic switch is connected with the ignition switch and the rocker switch, and the rocker switch is connected with the engine ECU and a backlight power source. When the automobile is in a normal running state, the self-locking electromagnetic switch is in a connected state, the rocker switch is in a zero-gear state, the ignition switch is in an ON gear, and the storage battery supplies power to the whole automobile; whenthe rocker switch is pressed down, the rocker switch is switched to a first gear from a zero gear, the self-locking electromagnetic switch is switched to a disconnected state, the storage battery andthe whole automobile are powered off, when the rocker switch is loosened, the rocker switch is switched to the zero gear from the first gear, and the storage battery and the whole vehicle are poweredoff; the rocker switch is continuously pressed down to be switched to the first gear from the zero gear, the self-locking electromagnetic switch is in a connected state, and the storage battery supplies power to the whole automobile. The system has no power loss, avoids serious power shortage of the storage battery, and prolongs the service life of the storage battery.
本发明公开一种汽车紧急断电系统及其车辆,包括自锁式电磁开关、蓄电池、点火开关、翘板开关和发动机ECU;蓄电池与自锁式电磁开关连接,自锁式电磁开关分别与点火开关、翘板开关连接,翘板开关分别与发动机ECU和背光灯电源连接;车辆正常行驶状态,自锁式电磁开关处于接通状态,翘板开关处于0档状态,点火开关处于ON档,蓄电池为整车供电;按下翘板开关从0档切换到1档,自锁式电磁开关切换到断开状态,蓄电池与整车断电,当松开翘板开关时,从1档切换到0档,蓄电池与整车断电;继续按下翘板开关从0档切换到1档,自锁式电磁开关处于接通状态,蓄电池为整车供电。该系统无功率损耗,避免了蓄电池严重亏电情况,提高蓄电池使用寿命。
