Parking assistance system and parking assistance method

摘要

A parking assistance system for a vehicle includes multiple on-board cameras (11, 12, 13, 14) each configured to capture an image of a surrounding area of the vehicle, overhead image generating means (21) for joining the captured multiple images and generating an overhead image viewed from above the vehicle, and display means (22) for displaying the generated overhead image and a steering wheel turning frame corresponding to a steering wheel turning position at which steering wheel turning is performed on the way of reverse movement of the vehicle to a predetermined target parking position.

1. A parking assistance system for a vehicle comprising:
a plurality of on-board cameras each configured to capture an image of a surrounding area of the vehicle; overhead image generating means for joining a plurality of images captured with the plurality of on-board cameras to thus generate an overhead image viewed from above the vehicle; display means for displaying the generated overhead image, a vehicle mark indicating actual position of the vehicle, and a steering wheel turning frame corresponding to a steering wheel turning position on the way of reverse movement of the vehicle to a predetermined target parking position, wherein the steering wheel turning position is a position where the vehicle approaches with a steering wheel turned in one of a right turn position and a left turn position, where the steering wheel is turned from the one of the right turn position and the left turn position to the other of the right turn position and the left turn position, and where the vehicle leaves with the steering wheel turned in the other of the right turn position and the left turn position, and wherein the steering wheel turning frame has a shape corresponding to an outline of the vehicle and has a larger width than a vehicle width of the vehicle; and image processing control means for causing the display means to display the steering wheel turning frame and a parking trajectory line leading to the steering wheel turning position on the generated overhead image, wherein the image processing control means causes the display means to display, as the parking trajectory lines, a tire turning angle association line indicating a turning angle of a tire associated with steering operation and an ideal tire turning angle line indicating a tire turning angle ideal for leading to the steering wheel turning position to which the vehicle is supposed to move next.
