1. A device for controlling a wiper of a vehicle, the device comprising:
a wiper actuator for driving the wiper of the vehicle;
a sensor for measuring a driving speed of the wiper; and
a controller configured to determine whether the wiper is in close contact with a windshield glass of the vehicle based on a relationship between a driving voltage applied to the wiper actuator and the driving speed measured by the sensor,
wherein the controller is further configured to:
determine a threshold speed value corresponding to the driving voltage, and
determine that a wiper blade of the wiper is not in close contact with the windshield glass of the vehicle when the driving speed exceeds the threshold speed value.
