AI Technical Summary

Technical Problem

Existing map management systems inaccurately determine the need for updating map information due to errors in road sign recognition and driver behavior, leading to unnecessary or erroneous update notifications.

Method used

A map management device that includes a recognition unit to identify road shape, type, and speed signs, determination units to assess differences between recognized and stored data, and a notification unit to prompt updates when predetermined thresholds are met, excluding temporary variations and congestion.

Benefits of technology

Accurately determines the need for map updates by considering driver behavior and road conditions, reducing false notifications and improving the relevance of update prompts.

Abstract

To determine the necessity of updating of map information with higher accuracy and give a notification of prompting updating.SOLUTION: A map management device 1 includes: an image recognition unit 11 that based on a picked-up image of an on-vehicle camera 2, recognizes at least any of a road shape, a road type, and a speed sign of a road on which an own vehicle V travels; a recognition determination unit 14 that determines the presence / absence of a difference between the recognized recognition information and map information; a vehicle speed determination unit 15 that determines the presence / absence of a difference between a speed of the own vehicle V and speed sign information included in the map information; and a notification unit 16 that in a case where it is determined in the recognition determination unit 14 that there is a difference and the number of times that it is determined in the vehicle speed determination unit 15 that there is a difference becomes more than or equal to a determination frequency threshold, gives a notification of prompting updating of the map information.SELECTED DRAWING: Figure 1
