Patent ID: 7891456

Claim:
An anti-drunk driving apparatus for a vehicle comprising: an alcohol drinking determination device which determines whether or not a first person seated in a driver's seat is drunk; a driving restriction device which restricts driving of the vehicle in a case where it is determined that the first person seated in the driver's seat is drunk by the alcohol drinking determination device; a driving intention presumption device which presumes whether or not a second person seated in the driver's seat has an intention to drive; a photograph device which photographs the face of the first person seated in the driver's seat, and the face of the second person seated in the driver's seat; and a person identification device which compares an image of the face of the first person seated in the driver's seat and an image of the face of the second person seated in the driver's seat, and thereby determines whether or not the first person seated in the driver's seat and the second person seated in the driver's seat are the same, wherein if it is determined by the person identification device that the first person seated in the driver's seat and the second person seated in the driver's seat are not the same, the driving restriction device restricts driving of the vehicle, wherein the driving intention presumption device presumes that the second person seated in the driver's seat has an intention to drive when the transmission of the vehicle is not in a park position or in a neutral position.
