The invention discloses a drunk driving judgment method based on vehicle circuit control. The method comprises the following steps: (1) a driver opens a vehicle door on one side of a driver seat, and a vehicle circuit control module disconnects a vehicle starting circuit; (2) after the vehicle door is opened, a driver seat seating detection module judges that a person sits in a driver seat, the driver seat seating detection module sends a signal to a vehicle circuit control module, and a vehicle starting circuit is kept in a disconnected state; (3) after a driver seat seating detection module detects that a person sits in the driver seat, an alcohol respiration detection module starts to work and detects whether the alcohol concentration of exhaled air of a driver reaches a preset threshold value or not, if the alcohol concentration reaches the preset threshold value, a vehicle starting circuit is kept in a disconnected state, and if the alcohol concentration does not reach the preset threshold value, the vehicle starting circuit is started; and (4) if the alcohol respiration detection module detects that the alcohol concentration reaches a preset threshold value, the driver still forcibly starts the vehicle, and a wireless communication module sends information to a traffic police control system network.

    本发明公开了一种基于车辆电路控制的酒驾判定方法,包括以下步骤:(1)驾驶员打开驾驶座一侧的车门,车辆电路控制模块断开车辆启动电路;(2)当车门打开后,驾驶座入座检测模块判断有人坐入驾驶位,驾驶座入座检测模块向车辆电路控制模块发送信号,保持车辆启动电路为断开状态;(3)驾驶座入座检测模块检测到有人坐入驾驶座后,酒精呼吸检测模块开始工作,检测驾驶员呼气的酒精浓度是否达到预设阈值,若酒精浓度达到预设阈值,则保持车辆启动电路为断开状态,若酒精浓度未达到预设阈值,则开启车辆启动电路;(4)若酒精呼吸检测模块检测到酒精浓度达到预设阈值,驾驶人仍然强行启动车辆,则无线通讯模块向交警控制系统网络发送信息。
