The invention relates to the technical field of drunk driving prevention, and discloses a drunk driving prevention method and device for an automobile, and the device comprises two ethanol sensors which are respectively arranged in a main driving column A and a co-driving column A; the two ethanol sensors are electrically connected with a trip computer ECU (Electronic Control Unit) through an automobile BCM (Body Control Module); and the automobile ignition switch is electrically connected with the trip computer ECU. When a main driver and a co-driver of a vehicle sit on a person, the alcohol sensor can detect gas exhaled by the person at the main driver and the co-driver, when the sensor detects that the alcohol content of the main driver exceeds the alcohol content of the co-driver, it is indicated that the main driver is drunk, the electronic control unit (ECU) can control an ignition switch of the vehicle not to be powered on, drunk driving is avoided, and if the alcohol content is lower than the alcohol content of the co-driver, drunk driving is avoided. At the moment, a loudspeaker of the automobile gives out prompt words, and the automobile is not stopped to be started.

    本发明涉及防酒驾技术领域,公开了一种汽车防醉驾方法及其装置,包括两个分别设置在主驾驶A柱和副驾驶A柱内的乙醇传感器;两个所述乙醇传感器经汽车BCM与行车电脑ECU电气连接;还包括与行车电脑ECU电性连接的汽车点火开关。本发明当车辆的主、副驾驶坐上人员后酒精传感器会检测到主、副驾驶位人员呼出的气体,当传感器检测到主驾驶的乙醇含量超过副驾驶就说明主驾驶醉驾,行车电脑ECU会控制汽车的点火开关不会通电,避免酒后驾车的行为,如果低于的话,可能是副驾驶醉驾造成的,此时汽车的扬声器是给出提示语,并不停止汽车启动。
