Patent ID: 8560169

Claim:
A vehicular parking feasibility determining system comprising transceiving means ( 11 ) that transmits electromagnetic waves so as to scan a predetermined angular range in the horizontal direction around a subject vehicle at predetermined time intervals, and receives reflected waves of the electromagnetic waves reflected from an object, reflection point detection means (M 1 ) that detects a reflection point at which electromagnetic waves are reflected from the object based on a result of reception of reflected waves by the transceiving means ( 11 ), parking space existence determining means (M 6 ) that determines the existence of a parking space (Sp) based on pre-stored subject vehicle body dimensional data and a sequence of the reflection points, parking feasibility determining means (M 9 ) that determines the feasibility of parking the subject vehicle from a current position thereof to the parking space (Sp), movable range calculation means (M 8 ) that calculates a movable range (Wx) in the subject vehicle width direction based on the sequence of reflection points, and parking space width calculation means (M 7 ) that calculates a width (Wy) of the parking space (Sp) in subject vehicle length direction based on the sequence of reflection points, the parking feasibility determining means (M 9 ) determining the feasibility of parking based on the movable range (Wx) and the width (Wy) of the parking space (Sp), wherein the system further comprises processing region setting means (M 3 ) that sets a predetermined processing region (R) formed from a first range in the subject vehicle width direction and a second range in subject vehicle length direction, the parking space existence determining means (M 6 ) determining that the parking space (Sp) exists when, among reflection points present within the processing region (R), a distance in the vehicle length direction between a pair of reflection points of the electromagnetic waves with adjacent angles in the horizontal direction is a predetermined value or greater.
