In-Vehicle Media Timing Around Autonomous Driving ODD Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for autonomous and semi-autonomous vehicles that extend trip duration to allow occupants to finish media-content exceed the available time constraints, leading to inefficient use of resources and increased complexity.
Innovation Solution
A system that adjusts the presentation of media content in a vehicular environment by estimating the time when an operational design domain (ODD) boundary will occur for a vehicle that is operating in an autonomous driving mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the vehicle extends the trip duration by selecting a longer route or driving at a slower speed, then the occupant can finish consuming the media-content item, but the trip efficiency and resource utilization deteriorate
Solution Approach 1:
Instead of extending the trip duration to match the media-content duration, the patent inverts the approach by adjusting the media-content duration to match the trip duration. The system modifies the media-content item to fit within the available trip time window, eliminating the need to alter the vehicle's route or speed for media consumption purposes.
Solution Approach 2:
The patent changes the duration parameter of the media-content item to align with the trip duration. By processing the media-content item to generate a modified version with adjusted duration, the system resolves the contradiction without affecting the vehicle's operational parameters such as route or speed.
2Ease of operation
If the vehicle extends the trip duration to allow complete media consumption, then the occupant's media consumption experience is improved, but the time cost and energy consumption increase
Solution Approach 1:
The patent reverses the traditional approach by not extending the trip to accommodate media content, but rather adjusting the media content to fit the trip duration. This inversion ensures that the occupant can consume the complete modified media-content item without adding extra time to the trip.
Solution Approach 2:
The system performs preliminary processing of the media-content item before playback to adjust its duration to match the available trip time. This advance preparation ensures that the media content can be completely consumed within the trip window without requiring post-trip extensions or interruptions.
3Duration of action of moving object
If the vehicle extends the trip duration, then the occupant can finish the media-content item, but the vehicle's schedule and resource allocation become less efficient
Solution Approach 1:
The patent extracts the duration adjustment function from the vehicle's routing and scheduling systems. By handling media-content duration adjustment as a separate media processing task rather than integrating it into the vehicle's navigation and resource management systems, the solution avoids increasing overall system complexity while still achieving the goal of complete media consumption within the trip window.

AI summary
Systems and methods described herein relate to adjusting presentation of media content in a vehicular environment. In one embodiment, a system for adjusting presentation of media content in a vehicular environment estimates a time at which an operational design domain (ODD) boundary will occur for a vehicle that is operating in an at least semi-autonomous driving mode. The system also processes automatically a media-content item presented to an occupant of the vehicle to generate a modified media-content item, the modified media-content item having a duration that results in presentation of the modified media-content item concluding at a predetermined time not later than the estimated time.
