Intelligent Range Map for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving range systems for electric vehicles are cumbersome and prone to user error, requiring manual toggling between one-way and two-way ranges, diverting driver attention from the road and increasing anxiety due to the scarcity of refueling stations, especially in low-population areas.
Innovation Solution
An intelligent driving range system that uses a processor to automatically determine and display either a one-way or two-way driving range based on the vehicle's energy level and location, allowing for convenient and accurate range information without manual user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a manual toggle is provided for switching between one-way and two-way driving ranges, then the system provides flexibility in displaying different range types, but the device complexity increases and ease of operation deteriorates due to frequent manual intervention
Solution Approach 1:
The system automatically determines and switches between one-way and two-way driving range displays based on detected location data and energy level information, eliminating the need for manual user toggling. The processor autonomously selects the appropriate range type by analyzing whether the vehicle is near refueling infrastructure or in remote areas, thereby simplifying operation while maintaining adaptability.
Solution Approach 2:
The system proactively determines the appropriate driving range display type before the user needs to make a decision, by continuously monitoring location and energy level data. This preliminary automatic selection prevents the need for last-minute manual configuration, reducing cognitive load and operational steps for the driver.
2Adaptability or versatility
If manual controls are required for configuring the range map, then the system allows user customization, but driver attention is diverted from the road reducing safety
Solution Approach 1:
The system performs automatic configuration of the driving range display type by processing location and energy level data without requiring driver interaction. This self-service approach maintains the adaptability of the system to different driving scenarios while completely eliminating driver distraction associated with manual control operations.
Solution Approach 2:
The system continuously receives feedback from location services and energy level sensors, automatically adjusting the range display type based on real-time conditions. This closed-loop feedback mechanism ensures appropriate customization without requiring driver input, thereby maintaining versatility while eliminating distraction.
3Measurement precision
If the system provides detailed range information requiring manual configuration, then measurement precision is improved, but loss of time increases due to frequent user interaction
Solution Approach 1:
The system performs preliminary automatic determination of the appropriate range display type by analyzing location and energy level data before the driver needs the information. This preliminary action maintains measurement precision of range information while eliminating the time loss associated with manual configuration during driving.
Solution Approach 2:
The processor automatically configures the range map display by processing location and energy level data without user intervention, thereby maintaining precise range information display while reducing configuration time to zero for the driver.

AI summary
An intelligent driving range system for a vehicle for automatically communicating a one-way driving range or a two-way (i.e. round-trip) driving range to a user of the vehicle. The driving range system utilizes a processor for determining whether to select the one-way distance range or the two-way distance range for communication. The processor determines the current driving range and may interface with a vehicle positioning system or navigation components for determining the current location of the vehicle. Either the one-way driving range or the two-way driving range is selected and communicated to the user of the vehicle. The selection may be based upon the current location of the vehicle. The driving range may be communicated by displaying a range map, by displaying a visual notification, or by sounding an audible notification.
