Electric Bicycle Map Generation via Operation Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map generation techniques require significant user input and are limited by relying solely on user evaluation, resulting in incomplete and inaccurate maps.
Innovation Solution
A control device and map generation method that obtain vehicle location and operation information, generate environment information based on this data, and associate it with location information to create an updated map that accurately reflects the travel environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a map is generated based on user evaluation results, then the map can be created with user feedback, but the information input is limited and requires a great deal of work
Solution Approach 1:
The system automatically generates environment information by having the vehicle itself collect operation information (acceleration, braking, steering) and use this data to infer travel environment characteristics, eliminating the need for manual user evaluation while maintaining accurate map information
Solution Approach 2:
The patent replaces the manual mechanical process of user evaluation with an automated electronic system that collects operation data from sensors and algorithmically generates environment information, significantly improving map generation efficiency
2Loss of information
If conventional map generation methods are used, then user feedback is incorporated, but the map information remains incomplete and inaccurate
Solution Approach 1:
The vehicle's existing operation data collection system serves multiple functions: it not only controls vehicle operation but also simultaneously collects data for generating environment information and updating map data, reducing overall system complexity while improving information completeness

AI summary
A control device includes: an obtaining unit configured to obtain location information of an electric bicycle and operation information obtained by the vehicle; a calculation unit configured to generate environment information indicating an estimated travel environment of the electric bicycle based on the operation information; and a storage unit configured to store the location information and the environment information. The calculation unit is configured to generate an updated map by associating the location information with the environment information, and reflecting the location information and the environment information on a map.
