EV Trip Planning via Mobile and Infotainment Charger Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to coordinate stops for an electric vehicle trip to maintain sufficient battery capacity while accommodating passenger desires, and to synchronize route adjustments made from multiple computing devices with respect to charging updates.
Innovation Solution
A system and method that allow a passenger to input adjustments to the trip route using a mobile device, indicating charging stops, and updating the route on the vehicle's display. The system recalculates the route based on available chargers, the vehicle's battery management system, and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trip route is adjusted to accommodate passenger desires by adding stops, then passenger satisfaction is improved, but battery capacity management becomes more difficult
Solution Approach 1:
The system continuously monitors battery capacity levels and automatically communicates with the route planning system to adjust stops and routing decisions. When battery capacity falls below thresholds, the system provides feedback to remove non-essential stops or modify the route to charging infrastructure, ensuring battery sufficiency is maintained while accommodating passenger requests.
Solution Approach 2:
The vehicle's battery management system automatically manages charging stops and route adjustments without requiring manual passenger intervention. The system self-regulates by monitoring battery levels and autonomously modifying the trip plan to ensure adequate battery capacity, while still allowing passengers to request stops within system constraints.
2Adaptability or versatility
If route adjustments are made from multiple computing devices, then flexibility and accessibility are improved, but synchronization of charging updates becomes more difficult
Solution Approach 1:
The vehicle's onboard computing system serves as a central intermediary that receives route adjustment requests from multiple external computing devices (smartphones, tablets, laptops). All charging update information flows through this central system, which maintains a single source of truth and distributes synchronized updates to all connected devices, preventing information loss or inconsistency.
Solution Approach 2:
The route planning system is designed to accept inputs from multiple types of computing devices simultaneously through standardized communication protocols. The system universally handles route modifications, charging stop additions, and battery status updates regardless of which device initiates the request, ensuring all devices remain synchronized through a common interface.

AI summary
Dynamic trip planning via a vehicle interface is provided. A system identifies a drive route for a vehicle. The drive route includes a first charger at a first location along the drive route configured to charge a battery of the vehicle. The system receives, via a communication session established with a mobile device, a command. The command is to add a stop to the drive route at a second location. The system determines, responsive to the command to add the stop at the second location, that the second location is within a threshold distance of a second charger configured to charge the battery of the vehicle. The system updates, based on a comparison of the first location with the second location, the drive route to add the second charger at the second location and remove the first charger at the first location.
