OBJECT DETECTION DEVICE FOR VEHICLE AND OBJECT DETECTION METHOD FOR VEHICLE

An object detection device for a vehicle includes a transmission and reception unit that transmits an electromagnetic wave and receives a reflected wave generated when the electromagnetic wave is reflected by an object around a subject vehicle, a reflecting point computation unit that computes a position of a reflecting point of the electromagnetic wave on the object based on a signal from the transmission and reception unit, a distance computation unit that computes a distance from the subject vehicle to the object based on the position of the reflecting point, an end point detection unit that detects at least one of an end point on the right side of the object and an end point on the left side thereof based on the position of the reflecting point, a shielding determination unit that determines whether the end point of the object is shielded by another object when viewed from the subject vehicle based on the computation result of the distance computation unit and the detection result of the end point detection unit, and an end point movement speed computation unit that computes a lateral movement speed of the end point of the object determined as not being shielded.
