The invention provides a detection method for preventing drunk driving, and the method is characterized in that the method comprises the steps: obtaining an air sample exhaled by a driver entering a vehicle, and detecting the alcohol content in the air sample; comparing the alcohol content in the air sample with a specified alcohol content, judging whether the alcohol content is less than the specified alcohol content, if so, starting a vehicle ignition system, and if not, not starting the vehicle ignition system; acquiring facial features of a driver before the vehicle is started and in the vehicle driving process, comparing the facial features, if the facial features are the same, enabling the vehicle to continue driving, and if the facial features are different, enabling the vehicle to stop driving; the audio features of the driver before the vehicle is started and in the vehicle driving process are obtained and compared, if the audio features are the same, the vehicle continues to run, and if the audio features are different, the vehicle stops running, and therefore the drunk driving prevention method has the advantage that drunk driving of the driver can be detected and prevented.

    本发明提出了一种预防酒后驾车的检测方法,其特征在于,包括获取进入到车辆内驾驶员呼出的空气样本并检测空气样本中的酒精含量;对比空气样本中的酒精含量与规定的酒精含量,判断是否小于规定的酒精含量,若小于规定的酒精含量则车辆点火系统启动,若大于酒精含量则车辆点火系统不启动;获取车辆启动前及车辆行驶过程中的驾驶员的面部特征并将二者对比,若面部特征相同则车辆继续行驶,若面部特征不同则车辆停止行驶;获取车辆启动前及车辆行驶过程中的驾驶员的音频特征并将二者对比,若音频特征相同则车辆继续行驶,若音频特征不同则车辆停止行驶,借此,本发明具有能对驾驶员的酒后驾车进行检测预防的优点。
