Abstract

A moving body control device includes an outside recognition unit, a reception unit, and a control unit. The control unit is configured to register feature points related to the designated parking position based on the recognition data of the outside as registered feature points, perform the automatic parking control for parking the moving body at the designated parking position based on the recognition data of the outside and the registered feature points, and update the registered feature points according to a match rate between the feature points obtained based on the recognition data of the outside when the automatic parking control is executed and the registered feature points.

First claim

What is claimed is:

1 . A moving body control device comprising a processor configured to:
acquire recognition data of an outside of a moving body; receive designation of a predetermined parking position from a user of the moving body via an input device of the moving body; detect a feature point map including a plurality of feature points from the recognition data of the outside; perform automatic parking control for parking the moving body at the predetermined parking position based on the recognition data of the outside and the predetermined parking position, and register the predetermined parking position as a designated parking position; register the feature point map including feature points related to the designated parking position based on the recognition data of the outside as registered feature points, and perform the automatic parking control for parking the moving body at the designated parking position based on the recognition data of the outside and the registered feature points; and determine whether to update the registered feature points according to a match rate between feature points at execution that are the feature map including the feature points obtained based on the recognition data of the outside during the automatic parking control is executed and the registered feature points.

2 . The moving body control device according to claim 1 , wherein
the processor is configured:
not to update the registered feature points when the match rate is equal to or greater than a first threshold; and
to update the registered feature points when the match rate is less than the first threshold.

3 . The moving body control device according to claim 2 , wherein
the processor is configured not to update the registered feature points, when the match rate is less than a second threshold which is lower than the first threshold, even when the match rate is less than the first threshold.

4 . A moving body control method including a processor of a moving body control device, wherein the processor of the moving body control device is configured to:
acquire recognition data of an outside of a moving body; receive designation of a predetermined parking position from a user of the moving body; detect a feature point map including a plurality of feature points from the recognition data of the outside; perform automatic parking control for parking the moving body at the predetermined parking position based on the recognition data of the outside and the predetermined parking position, and register the predetermined parking position as a designated parking position; register the feature point map including feature points related to the designated parking position based on the recognition data of the outside as registered feature points, and perform the automatic parking control for parking the moving body at the designated parking position based on the recognition data of the outside and the registered feature points; and determine whether to update the registered feature points according to a match rate between feature points at execution that are the feature map including the feature points obtained based on the recognition data of the outside during the automatic parking control is executed and the registered feature points.

5 . A non-transitory computer-readable storage medium storing a moving body control program causing a processor of a moving body control device to execute a process of:
acquiring recognition data of an outside of a moving body; receiving designation of a predetermined parking position from a user of the moving body; detecting a feature point map including a plurality of feature points from the recognition data of the outside; performing automatic parking control for parking the moving body at the predetermined parking position based on the recognition data of the outside and the predetermined parking position, and registering the predetermined parking position as a designated parking position; registering the feature point map including feature points related to the designated parking position based on the recognition data of the outside as registered feature points, and performing the automatic parking control for parking the moving body at the designated parking position based on the recognition data of the outside and the registered feature points; and determining whether to update the registered feature points according to a match rate between feature points at execution that are the feature map including the feature points obtained based on the recognition data of the outside during the automatic parking control is executed and the registered feature points.

6 . A moving body control device comprising a processor configured to:
acquire recognition data of an outside of a moving body; receive designation of a predetermined parking position from a user of the moving body via an input device of the moving body; perform automatic parking control for parking the moving body at the predetermined parking position based on the recognition data of the outside and the predetermined parking position, and register the predetermined parking position as a designated parking position; register feature points related to the designated parking position based on the recognition data of the outside as registered feature points, and perform the automatic parking control for parking the moving body at the designated parking position based on the recognition data of the outside and the registered feature points; and determine whether to update the registered feature points according to a match rate between the feature points obtained based on the recognition data of the outside during the automatic parking control is executed and the registered feature points, wherein a first threshold and a second threshold are set for the match rate, the processor is further configured to update the registered feature points, when the match rate is less than the first threshold and is equal to or greater than the second threshold, and the processor is configured not to update the registered feature points, when the match rate is less than the second threshold.

7 . The moving body control device according to claim 1 , wherein
the processor is configured to perform registration control to register feature points related to the designated parking position based on the recognition data of the outside, and the automatic parking control based on the recognition data of the outside and the registered feature points registered in the recognition control, and the match rate is a match rate between the feature points at execution obtained based on the recognition data of the outside during executing the automatic parking control and the registered feature points.

8 . The moving body control device according to claim 6 , wherein
the processor is configured to perform registration control to register feature points related to the designated parking position based on the recognition data of the outside, and the automatic parking control based on the recognition data of the outside and the registered feature points registered in the recognition control, and the match rate is a match rate between the feature points at execution obtained based on the recognition data of the outside during executing the automatic parking control and the registered feature points.

9 . The moving body control device according to claim 6 , wherein
the processor is configured: not to update the registered feature points when the match rate is equal to or greater than a first threshold; and to update the registered feature points when the match rate is less than the first threshold.
