According to the present invention, a drunk driving prevention device comprises: a weight measuring unit provided in a driver seat of a vehicle and measuring the weight of an occupant who seats on the driver seat; a storage unit storing the weight of the occupant measured by the weight measuring unit; an occupant determination unit determining whether the occupant is identical by comparing a first weight of the occupant who seats on the driver seat with a second weight stored in the storage unit immediately before the first weight is stored; a drinking determination unit requesting exhalation of the occupant after the weight is measured by the weight measuring unit, and determining a drinking state of the occupant by measuring the alcohol concentration with introduced exhalation by requesting the exhalation of the occupant again when the occupant determined by the occupant determination unit is determined as a person different from a previous occupant; and a control unit for controlling the starting of the vehicle in accordance with determination of the drinking state of the occupant from the drinking determination unit. Accordingly, the weight of the occupant who seats on the driver seat is measured and stored, his/her drinking state is determined and then, a weight change of the occupant is sensed to determine whether the occupant is changed such that the occupant who is in a drinking state is not allowed to start the vehicle, and the vehicle is not started to prevent drunk driving and an accident which may be caused by the drunk driving in case that the occupant is changed even when the vehicle is started by a third party.

    발명의 음주운전 방지장치에 따르면, 차량의 운전석에 구비되어, 상기 운전석에 착석하는 착석자의 몸무게를 측정하는 무게측정부; 상기 무게측정부로 측정되는 착석자의 몸무게를 저장하는 저장부; 상기 운전석에 착석한 착석자의 제1몸무게와, 상기 제1몸무게를 저장하기 직전에 저장부에 저장된 제2몸무게를 비교하여, 상기 착석자의 동일여부를 판단하는 착석자판단부; 상기 무게측정부에서 몸무게가 측정된 후 착석자의 날숨을 요청하되, 상기 착석자판단부에서 판단한 착석자가 이전 착석자와 다른 사람으로 판단하는 경우, 상기 착석자의 날숨을 재 요청하여 유입되는 날숨으로 알콜 농도를 측정하여 상기 착석자의 음주상태를 판단하는 음주판단부; 및 상기 음주판단부로부터 착석자의 음주상태 판단에 따라 상기 차량의 시동을 제어하는 제어부;를 포함한다. 본 발명의 효과는, 운전석에 착석한 착석자의 몸무게를 측정하고 저장한 다음, 음주상태를 판단하고, 착석자의 몸무게 변화를 감지하여 착석자의 변경 여부를 판단함으로써, 음주한 상태인 착석자가 차량의 시동을 ON 시키지 못하도록 하는 동시에, 제3자에 의해서 차량의 시동이 ON 상태가 되더라도 착석자가 변경되면 시동을 OFF하여 음주운전이 이루어지지 않도록 하는 동시에, 음주운전으로 발생될 수 있는 안전사고를 미연에 방지할 수 있는 음주운전 방지장치를 제공할 수 있다.
