A vehicle having a touch recognition function includes a touch pad recognizing a writing signal in a touch form input by a user. A display displays a touch trace corresponding to the writing signal recognized by the touch pad. A controller is configured to calculate writing coordinates of the writing signal, to obtain a writing recognition load by analyzing a touch trace speed of the calculated writing coordinates, and to increase a processing priority of a writing recognition task among service tasks within the vehicle when the obtained writing recognition load is greater than or equal to a reference value.
