Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems require manual intervention once a vehicle enters a charging station, as they lack detailed coordinate data for automatic travel control within the station.
Innovation Solution
A control system and device that acquire dimension information of the vehicle and generate travel path information using specific coordinate data within the charging station, enabling automatic travel to a charger without driver intervention, by determining compatible chargers based on battery type and software version, and generating paths to avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is required for vehicle travel within charging station, then system complexity is reduced, but productivity and ease of operation deteriorate due to driver involvement
Solution Approach 1:
The patent divides the coordinate data system into two distinct segments: map data for locations outside the charging station and coordinate data for locations within the charging station. This segmentation allows the system to use simplified local coordinate data for automatic travel control within the station, reducing the complexity burden while maintaining automation capability.
Solution Approach 2:
The patent introduces coordinate data as an intermediary element that bridges the vehicle's navigation system with the charging station's internal layout. This intermediary enables automatic travel control by providing the necessary spatial information without requiring complex integrated systems, thus improving ease of operation while managing device complexity.
2Measurement precision
If map data is used for navigation within charging station, then device complexity is reduced, but measurement precision and reliability worsen due to lack of detailed location data
Solution Approach 1:
The patent applies local quality by using different types of data for different spatial contexts: map data for external locations and detailed coordinate data for internal charging station locations. This ensures measurement precision is optimized for each specific context without unnecessarily increasing overall system complexity.
Solution Approach 2:
By segmenting the data system into map data and coordinate data, the patent provides high measurement precision where needed (within the charging station using coordinate data) while keeping the overall system manageable through clear data separation and distinct usage contexts.
3Productivity
If automatic travel control is implemented within charging station, then productivity improves, but device complexity increases due to need for integrated control system
Solution Approach 1:
The patent merges the automatic travel control function with the existing navigation system by integrating coordinate data processing into the vehicle's control device. This combination enables productivity improvement through automation while managing device complexity by utilizing existing system components rather than adding entirely separate systems.
Solution Approach 2:
The control device in the vehicle performs automatic travel control autonomously by processing coordinate data and executing navigation without requiring external control systems. This self-service approach improves productivity through automation while minimizing the increase in device complexity by using the vehicle's own computational resources.

AI summary
A control system includes one or more processors and one or more memories coupled to the one or more processors. The one or more processors are configured to execute processing. The processing includes acquiring dimension information indicating a dimension of a vehicle entering a charging station. The processing includes generating travel path information indicating a travel path of the vehicle in the charging station, based on the dimension information and coordinate data of locations located in the charging station. The coordinate data of the locations located in the charging station is different from map data that is coordinate data of locations located outside the charging station. The processing includes executing, based on the travel path information, first automatic travel control to control the vehicle to automatically travel to a charger in the charging station without intervention of a driver who drives the vehicle in the charging station.
