Abstract
A drunk driving prevention system includes a biometric authentication device that performs biometric authentication on a driver step-by-step at a request of startup of a vehicle, a drinking measurement device that measures a drunken state of the driver who completes the biometric authentication, a driver monitoring device that monitors a state of the driver in the vehicle while measuring the drunken state of the driver, and a controller that allows or blocks the startup of the vehicle based on the result of measuring the drunken state of the driver.
Claims14
A drunk driving prevention system, comprising:
- a biometric authentication device configured to perform biometric authentication on a driver step-by-step at a request of startup of a vehicle;
- a drinking measurement device configured to measure a drunken state of the driver who completes the biometric authentication, wherein the drinking measurement device includes a drinking measurement sensor to obtain information about a driver's respiratory volume and an alcohol component in a driver's inhaled breath, the drinking measurement sensor is located in a fan or a display of the vehicle;
- a driver monitoring device configured to monitor a state of the driver in the vehicle while measuring the drunken state of the driver by detecting, using a monitoring sensor, a weight and a body shape of a person seating on a driver's seat and a weight and a body shape of a passenger seating a passenger's seat;
- and
- a controller configured to:
- activate a drinking measurement operation of the drinking measurement device and a driver state monitoring operation of the driver monitoring device when the biometric authentication of the driver is successful,
- wherein the drinking measurement operation includes:
- receiving information about the weight and the body shape of the person seating on the driver's seat, comparing the information about the weight and the body shape of the person seating on the driver's seat with stored information about a weight and a body shape of a driver and determines whether the driver is in the driver's seat,
- determining whether the driver's respiratory volume obtained by the drinking measurement sensor is sufficient to measure the drunken state of the driver;
- in response to a determination that the driver is not in the driver's seat, or the driver's respiratory volume is insufficient, outputting a message for requesting re-measurement of respiration on the display and operating a red lamp on the drinking measurement sensor to provide a visualized signal for the re-measurement of respiration,
- in response to a determination that the driver is in the driver's seat and the driver's respiratory volume is sufficient, allowing or blocking the startup of the vehicle based on a result of the measuring of the drunken state of the driver;
- wherein the driver state monitoring operation includes:
- comparing the weight and the body shape of the passenger seating the passenger's seat with stored information about the weight and the body shape of the driver and determining whether the driver is in the driver's seat during the drinking measurement operation;
- and
- in response to a determination that the driver is not in the driver's seat outputting a warning and terminates the drinking measurement operation.

A method for preventing drunk driving, the method comprising:
- performing, by a biometric authentication device, biometric authentication on a driver step-by-step at a request of startup of a vehicle;
- measuring, by a drinking measurement device, a drunken state of the driver who completes the biometric authentication, wherein the drinking measurement device includes a drinking measurement sensor to obtain information about a driver's respiratory volume and an alcohol component in a driver's inhaled breath, the drinking measurement sensor is located in a fan or a display of the vehicle;
- monitoring, by a driver monitoring device, a state of the driver in the vehicle while measuring the drunken state of the driver by detecting, using a monitoring sensor, a weight and a body shape of a person seating on a driver's seat and a weight and a body shape of a passenger seating a passenger's seat;
- activating a drinking measurement operation of the drinking measurement device and a driver state monitoring operation of the driver monitoring device when the biometric authentication of the driver is successful;
- wherein the drinking measurement operation includes:
- receiving information about the weight and the body shape of the person seating on the driver's seat;
- comparing the information about the weight and the body shape of the person seating on the driver's seat with stored information about a weight and a body shape of a driver and determines whether the driver is in the driver's seat;
- determining whether the driver's respiratory volume obtained by the drinking measurement sensor is sufficient to measure the drunken state of the driver;
- in response to a determination that the driver is not in the driver's seat, or the driver's respiratory volume is insufficient, outputting a message for requesting re-measurement of respiration on the display and operating a red lamp on the drinking measurement sensor to provide a visualized signal for the re-measurement of respiration;
- in response to a determination that the driver is in the driver's seat and the driver's respiratory volume is sufficient, allowing or blocking, by a controller, the startup of the vehicle based on a result of the measuring of the drunken state of the driver;
- and
- wherein the driver state monitoring operation includes:
- comparing the weight and the body shape of the passenger seating the passenger's seat with stored information about the weight and the body shape of the driver and determining whether the driver is in the driver's seat during the drinking measurement operation;
- and
- in response to a determination that the driver is not in the driver's seat outputting a warning and terminates the drinking measurement operation.
