  • Patent number: 10391406
    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.
