The present disclosure relates to an input device for vehicle and control method of the same, and more particularly, to an input device for vehicle implemented as a plurality of sensor electrodes and control method of the input device. The input device may include: first sensor electrodes arranged in a first preset channel area with a first preset density; second sensor electrodes arranged in a second preset channel area with a second preset density, the second density being less than the first density; and a controller configured to determine a capacitive reference value of the input device based on first sensor value information that is collected from the first sensor electrodes and the second sensor electrodes.
