The invention relates to a vehicle-mounted expiration type alcohol detection system and a detection method thereof. The detection system comprises an alcohol primary screening system, an alcohol finescreening system, a sign central control system, a CAN bus and a vehicle-mounted display terminal. According to the invention, the primary screening system and the fine screening system are combined with the vehicle state condition to carry out comprehensive judgment, so that the whole expiratory alcohol detection system achieves more accurate judgment. Meanwhile, the system comprises a pluralityof alcohol sensors, and multi-scene judgment is realized via the state and data of a vehicle and other sensor data of the vehicle. According to the invention, the accuracy of the existing alcohol detection system is improved, and the compatibility of the alcohol detection system is also improved.

    本发明涉及一种用于车载的呼气式的酒精检测系统及其检测方法,该检测系统包括酒精初筛系统、酒精精筛系统、体征中控系统、CAN总线及车载显示终端;本发明中通过初筛系统以及精筛系统结合车辆状态情况进行综合的判断实现对整个呼气式酒精检测系统更为精确的判断。同时系统包含多个酒精传感器,与汽车自身的状态和数据,以及车辆的其他传感器数据,实现对多种场景的判断。本发明提高了现有的酒精检测系统的精确性同时也提高了酒精检测系统的兼容性。
