wherein the controller is configured for waking up of the second sensor by detecting the user's touch to the first capacitance sensor and the second capacitance sensor.

8. A method of controlling a vehicle, the method comprising:

storing, by a storage, ultrasonic pattern image data;

waking up, by a controller electrically connected to the storage, a second sensor in a response to a user's touching a first sensor, wherein the first sensor and the second sensor are electrically connected to the controller;

obtaining, by the controller, a fingerprint pattern image of the user from the second sensor;

according to a difference between an area value of a ridge area of the fingerprint pattern image and an area value of a valley area adjacent to the ridge area being less than a predetermined reference value, obtaining, by the controller, result data by assigning a weight to the area value of the valley area so that the difference between the area value of the ridge area and the area value of the valley area in the fingerprint pattern image increases; and

according to the result data and the ultrasonic pattern image data matching more than a predetermined matching value by comparing the result data and ultrasonic pattern image data, recognizing, by the controller, a fingerprint corresponding to the user,

wherein the assigning of the weight includes assigning a greater weight to a valley area value of an internal region of the fingerprint pattern image than a valley area value of an external region of the fingerprint pattern image.

9. The method according to claim 8 , further including: receiving, by an inputter electrically connected to the controller, the user's input to turn on a fingerprint recognition function of the controller; and according to the user's setting to wake up the fingerprint recognition function through the inputter, receiving, by the controller, the fingerprint pattern image from the second sensor.
