  • Publication number: 20170308762
    Abstract: An apparatus and method for determining drowsiness of a driver are provided. The apparatus includes an imaging device that obtains an image of the driver and a controller that determines (e.g., based on the image of the driver) when the driver is in a fatigue state, when the driver is in an eyelid closure state, and when the driver is in a wake-up state. The controller further determines that the driver is in a drowsiness state when after the fatigue state of the driver continues over a predetermined first time interval, the eyelid closure state and the wake-up state of the driver alternately and repetitively occur within a predetermined second time interval.

  • Patent number: 9522633
    Abstract: A driver customizable blind spot display method and apparatus are provided. The method of displaying blind spots of a vehicle via a screen mounted within a vehicle includes receiving information regarding positions of the driver's eyes from a driver state monitoring system and receiving current mirror setting information on a per in-vehicle mirror basis from a mirror drive unit. Blind spots and viewable spots are then calculated using the information regarding positions of the driver's eyes and the current mirror setting information. Particularly, the position of the driver's eyes is used to determine optimum mirror setting information. A mirror plane angle is then adjusted based on the optimum mirror setting information. A current blind spot coverage screen is then output to display the calculated blind spots and viewable spots.

  • Publication number: 20160052524
    Abstract: A system and method for alerting drowsy driving are provided. The system includes a d controller configured to analyze a driving pattern of a vehicle to detect a dangerous driving pattern. In addition, the controller is configured to analyze a face image of a driver to detect an eye pattern maintained for a predetermined period of time or longer. Further, the controller is configured to determine that the driver is driving while drowsy when the eye closing for the predetermined period of time or longer and the dangerous driving pattern are simultaneously detected.

  • Publication number: 20150032382
    Abstract: An apparatus and a method for determining a drowsy state include an information acquirer acquiring physiological information of a user, a mode determiner setting an operation mode among modes categorized according to variable applied to determine a drowsy state of the user. A threshold determiner sets a threshold for an application variable of the set mode based on data in a reference table stored in database (DB). A physiological index calculator calculates a measurement value for each of the application variables based on state information of the user acquired in real time from the information acquirer. A state determiner determines the drowsy state of the user by comparing a user table generated from the measurement value calculated for each of the application variables with the reference table.

  • Publication number: 20140342790
    Abstract: An apparatus and a method for a safe drive inducing game that includes a controller configured to execute the safe drive inducing game when a driver attention dispersion state is detected when a vehicle is driven. In addition, the controller recognizes a target driving path from vehicle driving information when executing the safe drive inducing game and generates a path guidance display according to the recognized target driving path to display on a game screen. The controller determines whether the vehicle follows the path guidance display by comparing a driving state of the vehicle with a position of the path guidance display displayed on the game screen and calculates a score of the safe drive inducing game according to whether the vehicle follows the path guidance display.
