EV Charging Media Selection Based on Autonomy and Session Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The variability in charging time for electric vehicle batteries and the need to provide appropriate media content during charging, considering autonomous driving modes and user preferences, poses challenges in efficiently utilizing user time during charging sessions.
Innovation Solution
Systems and methods determine the charging time for electric vehicle batteries and select media content items based on this duration, adjusting display settings according to autonomous driving levels and user profiles, and modifying content playback to match the charging time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If media content is provided during vehicle charging, then user time is utilized more effectively, but selection of appropriate content becomes difficult due to variable charging times
Solution Approach 1:
The system dynamically selects and adjusts media content based on the actual charging time duration. Content selection is not static but adapts to the variable charging time, allowing the system to provide appropriate content (movies, shows, music) that matches the determined time window, thereby resolving the contradiction between utilizing charging time and maintaining content selection flexibility
Solution Approach 2:
The system changes the parameter of content duration to match the charging time parameter. By determining the charging time first and then selecting content with matching duration parameters, the system ensures optimal content selection that fully utilizes the charging period without being constrained by fixed content lengths
2Ease of operation
If media content is displayed in the vehicle, then user experience is enhanced, but safety issues arise when the vehicle is in manual driving mode
Solution Approach 1:
The system applies different display quality settings to different viewing contexts. When the vehicle is in autonomous mode, full-quality media content is displayed on the instrument panel. When manual driving mode is detected, the system modifies the display quality or redirects content to passenger-facing displays, thereby maintaining safety while preserving media consumption capability for appropriate users
Solution Approach 2:
The system introduces an intermediary control mechanism that mediates between media content display and driving safety requirements. This intermediary layer monitors vehicle operating mode and automatically adjusts media display parameters, preventing direct conflict between entertainment and safety without requiring user intervention
3Reliability
If the vehicle operates at a lower autonomous driving level, then driver control is maintained, but media content display to the driver must be restricted
Solution Approach 1:
The system dynamically adjusts media display accessibility based on the autonomous driving level. At higher autonomy levels (4-5), driver-facing displays show full media content. At lower levels (0-3), the system progressively restricts or redirects media display away from the driver's field of view, creating a dynamic adaptation that maintains both driver control reliability and media consumption ease according to the current operating mode

AI summary
Systems and methods are described for determining an amount of time for charging a vehicle battery and selecting one or more media content items for display on a user device based on the amount of time for charging the vehicle battery. A level of driving autonomy of a vehicle is determined. An audio and/or video setting of the media content item is adjusted based on the level of driving autonomy.
