Abstract: A method of displaying parking assist information is used in a parking assist apparatus comprising a display and a control device. The control device displays a first parking space in a first display form on the display. The first parking space satisfies a parking condition that is preliminarily defined. When it is estimated that the first parking space will not satisfy the parking condition or a second parking space other than the first parking space will satisfy the parking condition, the control device displays the first parking space in a second display form different from the first display form on the display.

Abstract: A parking assist method for assisting parking of a subject vehicle uses a parking assist apparatus comprising a controller that guides the subject vehicle to a parking space and a display that displays the parking space. The parking assist method comprises: specifying an available parking space into which the subject vehicle can be parked; displaying the available parking space on the display; when the available parking space is in a parking-unavailable state that represents a state in which the subject vehicle cannot be parked into the available parking space, determining whether or not the parking-unavailable state is canceled; and when the parking-unavailable state is canceled before a first time passes, maintaining a display form of the available parking space on the display.

Abstract: A three-dimensional object detection device includes an image capturing unit, an image conversion unit, a three-dimensional object detection unit, a light source detection unit and a control unit. The image conversion unit converts a viewpoint of the images obtained by the image capturing unit to create bird's-eye view images. The three-dimensional object detection unit detects a presence of a three-dimensional object within the adjacent lane. The three-dimensional object detection unit determines the presence of the three-dimensional object within the adjacent lane-when the difference waveform information is at a threshold value or higher. The control unit set a threshold value higher so that the three-dimensional object is more difficult to detect in a forward area than rearward area with respect to a line connecting the light source and the image capturing unit when the light source has been detected.

Abstract: A three-dimensional object detection device includes an image capturing unit, an image conversion unit, a three-dimensional object detection unit, a three-dimensional object assessment unit and a control unit. The image conversion unit converts a viewpoint of the images obtained by the image capturing unit to create bird's-eye view images. The three-dimensional object detection unit detects a presence of a three-dimensional object within the predetermined detection area by vehicle width direction detection processing. The three-dimensional object assessment unit assesses whether the three-dimensional object detected is another vehicle that is present within the predetermined detection area. The control unit suppresses assessment by the three-dimensional object assessment unit that the three-dimensional object is a vehicle when a specified detection position has moved rearward within the detection area in a host vehicle progress direction and arrived at a predetermined position in the host vehicle progress direction within the detection area.

Abstract: A three-dimensional object detection device has an image capturing unit, a first object detection unit, a light source detection unit, a second object detection unit, a degree-of-clouding calculation unit and a controller. The image capturing unit captures images rearward of a vehicle. The first object detection unit detects a presence of a three-dimensional object from the captured images. The second object detection unit detects a presence of a three-dimensional object from a detection result of the light source detection unit. The degree-of-clouding calculation unit calculates a degree of lens clouding from the captured images. The controller assess the object as an adjacent vehicle in an adjacent lane from the degree of lens clouding when the degree of lens clouding is equal to or greater than a predetermined value and from the presence of the object in the captured images when the degree of lens clouding is less than the value.
