1. A device installed in a first vehicle for recognizing a width of a second vehicle, the device comprising:
a weight selecting device configured to select at least one weight among a plurality of weights based on a degree of shaking of the first vehicle in a left and right direction and output the selected weight as selected weight information when the second vehicle, which initially follows the first vehicle, overtakes the first vehicle;
a vehicle width calculation device configured to calculate a vehicle width of the second vehicle that has overtaken the first vehicle based on front region image information containing the second vehicle that has overtaken the first vehicle, and output the calculation result as image vehicle width calculation information for the second vehicle;
a weight applying device configured to apply the selected weight information to the image vehicle width calculation information and output the result as vehicle width information for the second vehicle;
an overtaking sensing device configured to determine whether the second vehicle is overtaking the first vehicle;
a front camera configured to obtain the front region image information;
a yaw rate sensor configured to obtain the degree of the shaking of the first vehicle in the left and right directions;
a rear radar configured to sense the second vehicle; and
a speed sensor configured to sense a speed of the first vehicle.
