EV Fleet Control Using Geofenced Site-Specific Vehicle Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lightweight electric utility vehicles (LEUVs) require manual configuration for site-specific operation, which is inefficient and does not account for varying topography, climate, and regulatory differences across locations.
Innovation Solution
An intelligent fleet management system automatically applies site-specific operational characteristics to vehicles based on geographic boundaries, using onboard controllers and network communication to adjust settings such as speed, battery charge, and telemetry in response to site IDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used for site-specific operation, then vehicle settings can be customized, but the process is inefficient and requires continuous manual intervention
Solution Approach 1:
The vehicle system automatically detects its geographic location using GPS coordinates and retrieves applicable operational characteristics from a server without requiring manual configuration. The onboard controller autonomously configures speed limits, battery parameters, and other operational settings based on the detected site, eliminating the need for continuous manual intervention while maintaining site-specific customization.
2Adaptability or versatility
If fixed operational characteristics are applied to all vehicles, then configuration is simplified, but site-specific conditions such as topography, climate, and regulations cannot be accounted for
Solution Approach 1:
The system assigns different operational characteristics to different geographic locations (sites). Each site has its own specific speed limits, battery charge/discharge characteristics, and operational parameters tailored to local conditions such as topography, climate, and regulations. The onboard controller automatically applies the appropriate local characteristics based on the vehicle's detected location, enabling site-specific adaptation without requiring complex manual configuration at each location.
3Reliability
If dynamic adjustment of operational characteristics is implemented, then vehicle safety and compliance are enhanced, but system complexity increases
Solution Approach 1:
The system continuously monitors the vehicle's geographic location using GPS and automatically adjusts operational characteristics based on the detected site. The onboard controller receives location data, queries the server for applicable characteristics, and dynamically configures vehicle parameters such as speed limits and battery management settings. This closed-loop feedback mechanism ensures vehicle safety and compliance with local regulations while using standardized communication protocols to manage system complexity.
