Vehicle and control method thereof

A method of controlling a vehicle, comprising:

• providing one character input interface;
• sensing a plurality of sub gestures sequentially through a touch input apparatus of the vehicle;
• determining whether to display a character or to execute control commands according to a direction, a start location, and a time difference among the sensed plurality of sub gestures;
• and
• displaying a character corresponding to a gesture including a first sub gesture and a second sub gesture through the one character input interface upon a determination that a difference between a direction of a first sub gesture of the plurality of sensed sub gestures and a direction of a second sub gesture sensed within a first delay time period starting at a time at which the first sub gesture ends is greater than or equal to a reference direction difference,
• wherein the step of displaying the character comprises:
• upon a determination that the difference between the direction of the first sub gesture and the direction of the second sub gesture is smaller than the reference direction difference, and upon a determination that a difference between a start location of the first sub gesture and a start location of the second sub gesture is greater than or equal to a reference start location difference, displaying the character corresponding to the gesture including the first sub gesture and the second sub gesture through the character input interface,
• wherein upon the determination that the difference between the direction of the first sub gesture and the direction of the second sub gesture is smaller than the reference direction difference, and upon a determination that the difference between the start location of the first sub gesture and the start location of the second sub gesture is smaller than the reference start location difference, controlling the character input interface sequentially according to control commands respectively corresponding to the first sub gesture and the second sub gesture;
• wherein the method further comprises:
• storing the plurality of sensed sub gestures sequentially in a first buffer of the vehicle;
• and
• simultaneously storing a plurality of control commands corresponding to the plurality of sensed sub gestures in a second buffer of the vehicle.

A vehicle, comprising:

• a display configured to provide one character input interface;
• and
• a touch input apparatus including a touch pad and configured to sense a plurality of sub gestures sequentially through the touch pad,
• wherein the vehicle is configured to:
• determine whether to display a character or to execute control commands according to a direction, a start location, and a time difference among the sensed plurality of sub gestures, and
• display a character corresponding to a gesture including a first sub gesture and a second sub gesture on the one character input interface, when a difference between a direction of the first sub gesture of the plurality of sensed sub gestures and a direction of the second sub gesture sensed within a first delay time period starting at a time at which the first sub gesture ends is greater than or equal to a reference direction difference,
• wherein the vehicle further comprises a storage device including a first buffer configured to store the plurality of sensed sub gestures sequentially, and a second buffer configured to store a plurality of control commands corresponding to the plurality of sensed sub gestures simultaneously,
• wherein upon a determination that the difference between the direction of the first sub gesture and the direction of the second sub gesture is smaller than the reference direction difference, and if a difference between a start location of the first sub gesture and a start location of the second sub gesture is greater than or equal to a reference start location difference, the vehicle controls the character input interface to display the character corresponding to the gesture including the first sub gesture and the second sub gesture, and
• wherein upon a determination that the difference between the direction of the first sub gesture and the direction of the second sub gesture is smaller than the reference direction difference, and upon a determination that the difference between the start location of the first sub gesture and the start location of the second sub gesture is smaller than the reference start location difference, the vehicle controls the character input interface sequentially according to control commands respectively corresponding to the first sub gesture and the second sub gesture.
