[0038] The parking assist device according to the first embodiment of the present invention can be mounted on a vehicle (hereinafter, the vehicle on which the parking assist device according to the first embodiment of the present invention is mounted is referred to as "own vehicle"). Such as figure 1 As shown, the parking assistance device according to the first embodiment of the present invention includes a control device (controller) 1 , a surrounding condition sensor 2 , a vehicle condition sensor 3 , an input device (interface) 4 , a storage device 5 and a presentation device 6 .

[0039] The surrounding situation sensor 2 detects the surrounding situation of the own vehicle including the front situation, the rear situation, and the side situation of the own vehicle. The surrounding conditions of the vehicle that the surrounding condition sensor 2 can detect include buildings, walls, columns, signs, other vehicles, bicycles and other stationary three-dimensional...

[0079] In the second embodiment of the present invention, a case where the surrounding conditions of the parking target position are detected (learned) multiple times by repeating parking at the parking target position a plurality of times will be described. By integrating multiple detection results, it is possible to supplement obstacles and feature points that cannot be detected during one stop. Therefore, the accuracy of map data and the like generated based on the surrounding conditions of the parking target position can be improved.

[0080] The structure of the parking assist device according to the second embodiment of the present invention is the same as that of the parking assist device according to the first embodiment of the present invention. figure 1 As shown, a control device (controller) 1 , a surrounding state sensor 2 , a vehicle state sensor 3 , an input device (interface) 4 , a storage device 5 and a prompting device 6 are provided.

Abstract

Provided is a parking assist method which is capable of storing the surrounding situation around a parking target location, is the surrounding situation being suitable to be referenced during automatic parking. The parking assist method for storing the surrounding situation around a parking target location and executing automatic parking by using the stored surrounding situation, when a vehicle isparked at a parking target location, includes: a step (S12) for detecting the surrounding situation; a step (S14) for presenting the detected surrounding situation; a step (S14) for receiving, by anoccupant, an input about whether the presented surrounding situation is suitable; and a step (S15, S16) for storing the surrounding situation, when the suitability input that the occupant has input tobe suitable is obtained.

Description

technical field [0001] The invention relates to a parking assistance method and a parking assistance device for performing automatic parking. Background technique [0002] Conventionally, a method is known in which the surrounding environment of the laser distance sensor is measured multiple times while moving the laser distance sensor, and the values ​​measured for each time are combined to create an image map of the environment (see Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2005-326944 [0004] However, when parking at the parking target position, detecting the surrounding conditions of the parking target position, and storing the surrounding conditions for reference at the time of automatic parking, in the case of applying the technology of Patent Document 1, it is often difficult to store due to the parking environment. Based on the surrounding conditions of reference. Contents of the invention [0005] In view of th...
