1. A method for searching for a route using road-shoulder parking state information in a vehicle operating in conjunction with a server via a wireless communication network, the method comprising:
identifying, by a controller, at least one vehicle stopped on a shoulder of a road by analyzing an image captured by a camera while the vehicle is being driven;
determining, by the controller, the at least vehicle to be reported as being stopped on the shoulder of the road among the identified vehicles stopped on the shoulder of the road; and
generating, by the controller, a road-shoulder stop report message corresponding to the determined at least one vehicle to be reported as being stopped on the shoulder of the road, and transmitting the road-shoulder stop report message to the server,
wherein the identifying of the vehicles stopped on the shoulder of the road includes:
detecting, by the controller, the at least one vehicle stopped on a left or right shoulder of the road by analyzing an image captured by a front camera and calculating a first coordinate point representing a position of the detected vehicle;
calculating, by the controller, a second coordinate point representing a position of the detected vehicle by analyzing an image captured by a rear camera; and
determining, by the controller, the at least one vehicle to be stopped on the shoulder of the road by comparing the first coordinate point and the second coordinate point,
wherein the determining of the at least one vehicle stopped on the shoulder of the road by comparing the first coordinate point and the second coordinate point includes:
determining, by the controller, the detected vehicle to be the vehicle stopped on the shoulder of the road, when the first coordinate point and the second coordinate point match each other; and
determining the detected vehicle to be traveling on the shoulder of the road, when the first coordinate point and the second coordinate point do not match each other,
wherein the determining of the at least one vehicle to be reported as being stopped on the shoulder of the road includes:
calculating, by the controller, an occupancy rate at which the at least one vehicle determined to be stopped on the shoulder of the road occupies an outermost lane; and
determining, by the controller, the at least one vehicle to be reported as being stopped on the shoulder of the road by comparing the calculated occupancy rate and a predetermined reference value.
