Driving assistance apparatus and driving assistance method
First Claim
1. A driving assistance apparatus that assists a driver of a vehicle in positioning the vehicle with respect to a target on a road surface before stopping the vehicle, the driving assistance apparatus comprising:
- a vehicle-mounted camera that captures a video image showing an area around the vehicle, the area including the target;
an image generation section that generates a positioning video image to position the vehicle with respect to the target, based on the video image captured by the vehicle-mounted camera, even when the target is beneath the vehicle;
a display monitor that displays the positioning video image; and
an acquisition section that acquires a relative location of the target with respect to the vehicle, whereinthe image generation section selectively generates the positioning video image in a first display mode or the positioning video image in a second display mode based on the relative location of the target,the first display mode being a display mode in which the target moves with respect to the vehicle,the second display mode being a display mode in which the vehicle moves with respect to the target,the image generation section generates the positioning video image by combining a vehicle outline image with the video image captured by the vehicle-mounted camera, the vehicle outline image being indicative of an outline of the vehicle, andthe image generation section generates the positioning video image by combining a target image with the vehicle outline image, the target image being indicative of the location of the target, when the target is hidden from the vehicle-mounted camera by the vehicle.

Abstract
A driving assistance apparatus captures with a camera a video image showing an area, which surrounds a vehicle and includes a target on a road surface; generates a positioning video image for positioning the vehicle; and displays the generated positioning video image on a display monitor. The driving assistance apparatus also acquires a relative location of the target with respect to the vehicle. Further, based on the relative location of the target, the driving assistance apparatus switches the display mode of the positioning video image displayed on the display monitor between a first display mode (in which the target moves with respect to the vehicle) and a second display mode (in which the vehicle moves with respect to the target).

7. A driving assistance method that assists a driver of a vehicle in positioning the vehicle with respect to a target on a road surface before stopping the vehicle, the driving assistance method comprising:
-
capturing a video image showing an area around the vehicle, the area including the target; acquiring a relative location of the target with respect to the vehicle; selecting, as a display mode used when the video image showing the area around the vehicle is to be displayed in a display monitor, a selected display mode that is one of a first display mode and a second display mode, based on the relative location of the target, the first display mode being a display mode in which the target moves with respect to the vehicle, the second display mode being a display mode in which the vehicle moves with respect to the target; generating a positioning video image by combining a vehicle outline image with the video image by combining a vehicle outline image with the video image captured by the vehicle-mounted camera, the vehicle outline image being indicative of an outline of the vehicle of an outline of the vehicle; generating the positioning video image to position the vehicle with respect to the target even while the target is beneath the vehicle by combining a target image with the vehicle outline image, the target image being indicative of the location of the target, when the target is hidden from the vehicle-mounted camera by the vehicle; and displaying, in the display monitor, the video image showing the area around the vehicle in the selected display mode.
