An apparatus for detecting an alcohol component of a driver's breath includes an inlet that absorbs a driver's exhalation and a passenger's exhalation, respectively, a sensor that detects an alcohol component in the driver's exhalation or the passenger's exhalation, a driver valve controlled to be opened or closed to allow the driver's exhalation to be introduced into the sensor and a passenger valve controlled to be opened or closed to allow the passenger's exhalation to be introduced into the sensor, and a controller that determines whether a passenger is on board a vehicle and controls the driver valve and the passenger valve to be open or closed based on a determination result. Therefore, the driver's breath is distinguished from the passenger's breath and the influence of the passenger is removed to detect the alcohol component in the driver's breath, thereby accurately determining the driver's drinking state.

The present application relates to the field of alcohol detection, and particularly to an intelligent identity-authentication alcohol detector. One technical solution comprises an intelligent identity-authentication alcohol detector, comprising a base, a mounting seat, and a connecting arm; the mounting seat is provided on the base, and a face information acquiring module is provided on the mounting seat; the connecting arm is rotatably provided on the base, and a breathing opening for alcohol detection is provided on the connecting arm; and the connecting arm is used for driving the breathing opening for alcohol detection to a position where the face information acquiring module acquires the face information of a subject.

Provided is a vehicle stop support system for supporting vehicle stop in an emergency condition. The vehicle stop support system sets a target time period based on physical abnormality of a driver; sets an allowable lateral acceleration, based on the abnormality; estimates a time period required to reach each of a plurality of stop point candidates; estimates a lateral acceleration to be generated during traveling of a vehicle to each of the candidates; sets a stop point; and controls the vehicle to travel to the stop point and stop at the stop point. The system is operable to set, as the stop point, one of the candidates which satisfies a condition that the lateral acceleration estimated with respect thereto is equal to or less than the allowable lateral acceleration, and the required time period estimated with respect thereto is equal to or less than the target time period.
