Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle conditions and operations often hinder passengers' ability to rest comfortably during long trips, despite the need for some operational lighting and other functions.
Innovation Solution
A system that identifies resting passengers and adjusts vehicle conditions, such as lighting and volume, while determining a travel route that minimizes disruptive forces and external factors to enhance restfulness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interior lighting is increased to provide adequate illumination for vehicle operation, then vehicle operational control is improved, but passenger rest conditions deteriorate
Solution Approach 1:
The patent segments the vehicle interior into different lighting zones with different illumination levels. Task lighting is provided in the driver area while the passenger area receives minimal or no lighting, allowing operational control to be maintained without compromising passenger rest conditions.
Solution Approach 2:
The patent applies local quality by providing differentiated lighting conditions in different parts of the vehicle. The driver's workspace maintains adequate illumination for safe operation, while passenger areas are dimmed or darkened to promote rest, creating locally optimized conditions for each function.
2Productivity
If vehicle operations are optimized for efficiency and speed, then productivity is improved, but rest disruption factors increase
Solution Approach 1:
The patent implements dynamic adjustment of vehicle operations based on detected passenger rest states. When rest mode is activated, the vehicle dynamically modifies acceleration profiles, deceleration rates, and route selection to minimize disruptive forces, while still maintaining productive travel through optimized routing and timing.
Solution Approach 2:
The patent changes operational parameters such as acceleration, deceleration, and routing when rest mode is detected. The vehicle system modifies these parameters to reduce rest disruption factors while maintaining overall travel efficiency through intelligent parameter adjustment rather than simply reducing speed.
3Object-affected harmful factors
If automated vehicle control is increased to improve rest conditions, then passenger rest quality is improved, but system complexity increases
Solution Approach 1:
The patent employs a multi-functional automated system that performs multiple tasks: detecting passenger rest states, adjusting interior lighting, modifying vehicle operations, and selecting optimal routes. This universal system consolidates multiple functions into a single integrated control architecture, managing complexity through functional integration.
Solution Approach 2:
The system uses self-service by automatically detecting when passengers are resting through sensors and autonomously adjusting vehicle operations and interior conditions without requiring manual input. The system serves itself by using its own sensor data to trigger appropriate operational modifications.
Data Source
AI summary
A method for operating a vehicle includes entering a rest mode and altering at least one vehicle condition to be more conductive to rest. The method identifies a body position of a first passenger and determines a first body vector from the body position to a first vehicle reference point. The method determines a travel route configured to minimize at least one rest disruption factor based at least in part on the first body vector and initiates the determined travel route.
