  • Patent number: 10366611
    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 specifies a parking space on the basis of a parking condition that is preliminarily defined, and displays the specified parking space in a predetermined display region defined on a display surface of the display. When the area of a region that is occupied by the parking space and displayed in the display region is less than a predetermined value, the control device displays a specific mark on the display. The mark indicates that the parking space that is not displayed in the display region exists.

  • Publication number: 20190197322
    Abstract: A method of determining obstacles determines if a detected object detected outside a subject vehicle is an obstacle for the subject vehicle on the basis of a predetermined determination criterion. In this method, a determination is made whether or not the detected object detected outside the subject vehicle is a driver or passenger of the subject vehicle. When the detected object is not the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a first determination criterion. When the detected object is the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a second determination criterion with which the detected object is less likely to be determined as an obstacle for the subject vehicle than with the first determination criterion.

  • Publication number: 20190054927
    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.

  • Patent number: 10163016
    Abstract: A parking space detection method detects a parking space in an empty state from a captured image acquired by a camera configured to capture an image of a parking lot. The method includes detecting a parked vehicle existing in a parking space on the far side from the subject vehicle and adjacent to a determination target parking space for which the empty state is determined and measuring a lateral length of the parked vehicle on a surface located at the side of the determination target parking space. When the lateral length is a predetermined value or more, the determination target parking space is detected as a parking space in the empty state.

  • Patent number: 10142595
    Abstract: A driving assistance device includes a camera, a moving object detector, a candidate reflection region detector, a predetermined position brightness detector and a cause determiner. The moving object detector and the candidate reflection region detector set a detection region for detecting, from image data captured by the camera, an existence of an adjacent vehicle in an adjacent lane. The predetermined position brightness detector detects a candidate light projecting object which projects light with brightness equal to or higher than a predetermined threshold value. The cause determiner determines whether or not there exists a candidate light projecting object which indicates the existence of the adjacent vehicle in the detection region.

  • Patent number: 10096124
    Abstract: A water droplet detection device has an image capturing unit and a water droplet detection unit. The image capturing unit has a photographic optical system that an area captures an image of a predetermined area. The water droplet detection unit sets an arbitrary attention point in the captured image, a plurality of first reference points inside an imaginary circle of a predetermined radius having the attention point as a center the imaginary circle, and a plurality of second reference points corresponding to the first reference points outside the imaginary circle. The water droplet detection unit detects edge information between the first reference points and second reference points, and assesses a circularity strength of the edge information to detect a water droplet attached to the photographic optical system. The water droplet detection device can be used with an image conversion unit to form a three-dimensional object detection device.

  • Patent number: 9862320
    Abstract: A three-dimensional object detection device has a camera, a three-dimensional object detection unit, a lens cleaning device, a lens state assessment unit and a controller. The camera has a lens for forming an image of an area rearward of a vehicle. The three-dimensional object detection unit detects a three-dimensional object rearward of the vehicle based on the captured images. The lens cleaning device sprays cleaning fluid to clean the lens of the camera. The lens state assessment unit accesses whether the lens is in a predetermined state subject to control based on a timing at which cleaning fluid is sprayed on the lens. The controller suppresses detection of the three-dimensional object by retaining detection or assessment results for a predetermined length of time that were obtained immediately before the lens was assessed to be in the state subject to control, upon assessment that the lens state is subject to control.

  • Patent number: 9832444
    Abstract: A three-dimensional object detection device includes an image capturing unit, an image conversion unit, a three-dimensional object detection unit and a light source detection 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 three-dimensional object detection unit set a threshold value lower so that the three-dimensional object is more readily detected in a rearward area than forward area with respect to a line connecting the light source and the image capturing unit.

  • Patent number: 9804386
    Abstract: A camera device includes image capturing device, a lens cleaning device, an adhesion state assessment unit and a controller. The image capturing device is installed on a vehicle and has a lens for forming an image of the vehicle surroundings. The lens cleaning device cleans the lens by spraying a cleaning fluid on the lens in accordance with a predetermined lens cleaning step, in which at least a supply time for supplying cleaning fluid to the lens surface is predetermined. The adhesion state assessment unit is programmed to assess an adhesion state of contamination from a distribution of pixels corresponding to foreign matter adhered to the lens based on a captured image. The controller is programmed to extend the time until a time to start supplying the cleaning fluid in the lens cleaning step as the number of pixels corresponding to foreign matter adhered to the lens increases.
