Abstract: An object detection device for a vehicle includes a transmission and reception unit that transmits an electromagnetic wave and receives a reflected wave, a reflecting point computation unit that computes a position of a reflecting point of the electromagnetic wave on the object, a distance computation unit that computes a distance from the subject vehicle to the object, 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, a shielding determination unit that determines whether the end point of the object is shielded by another object when viewed from the subject vehicle, 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.

Abstract: A roadside object present at the side of a subject vehicle travel path and a preceding vehicle at a speed equal to or greater than a predetermined speed are detected based on points derived by transmitting an electromagnetic beam forward of the subject vehicle and projecting reflection points obtained onto a two-dimensional plane, a determination is made when the preceding vehicle passes near the roadside object as to whether it moved toward the travel path within a predetermined time before and after the passage, and the roadside object is not determined to be the obstacle when it is determined to have moved toward the travel path, thereby preventing the roadside object from being misidentified as the obstacle owing to erroneous recognition of it having intruded into the travel path of the subject vehicle when detecting the object using an electromagnetic beam.

Abstract: A railroad crossing barrier estimating apparatus and a vehicle that incorporates therein such a railroad crossing barrier estimating apparatus are provided. When at least one of an external object the transverse width of which increases over time and an external object having a given length at a certain height from the ground is detected, the vehicle or the railroad crossing barrier estimating apparatus estimates the detected external object as a railroad crossing barrier.

Abstract: 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 detecti

Abstract: An object detection device for a vehicle includes a transmitting-receiving unit, a reflection point computation unit, an object width computation unit, a representative point setting unit, a lateral relative velocity computation unit, a memory unit, and a lateral relative velocity correction unit. The transmitting-receiving unit transmits an electromagnetic wave. The object width computation unit computes a width of the object. The lateral relative velocity computation unit computes a lateral relative velocity. The memory unit records the object as a width-widening static object when the object is a static object and an amount of increase in the width of the object is greater than a predetermined value, based on a detection history of the object detected at each of the predetermined cycle. The lateral relative velocity correction unit corrects the lateral relative velocity, when the object recorded as the width-widening static object is detected at a left end part or a right end part of a detection region.
