Patent ID: 8548769

Claim:
A device for detecting a stopped state of a vehicle having a plurality of tires and a body in which a plurality of fenders respectively corresponding to the tires are formed, comprising: a plurality of groups of distance sensors respectively corresponding to the tires and the fenders; and an arithmetic unit connected to the groups of the distance sensors, wherein each of the groups of the distance sensors comprises: a front distance sensor scanning the front portion of the outer side surface of the tire corresponding to the group of the distance sensors and detecting a coordinate of a portion of the front portion of the tire at which the tire expands the most outward along the direction of the side surface of the tire as a first point; a rear distance sensor scanning the rear portion of the outer side surface of the tire corresponding to the group of the distance sensors and detecting a coordinate of a portion of the rear portion of the tire at which the tire expands the most outward along the direction of the side surface of the tire as a second point; an upper distance sensor scanning the upper portion of the outer side surface of the tire corresponding to the group of the distance sensors and detecting a coordinate of a portion of the upper portion of the tire at which the tire expands the most outward along the direction of the side surface of the tire as a third point; and a fender part distance sensor scanning the fender corresponding to the group of the distance sensors and detecting a coordinate of a portion of the fender at which the fender expands the most outward along the direction of the side surface of the body as a fourth point, and the arithmetic unit detects an evaluation point of the tire based on a coordinate of a centroid point of a triangle formed with the first, second and third points detected by the group of the distance sensors, and detects an evaluation point of the fender based on the coordinate of the fourth point detected by the group of the distance sensors so as to detect the stopped state of the vehicle based on the coordinate of the evaluation point detected about each of the tires and the coordinate of the evaluation point detected about each of the fenders.
