Vehicle Occupant Sleep State Management for Safe Takeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle assistance systems fail to effectively manage the sleep state of vehicle occupants during autonomous driving, leading to potential hazards due to inadequate takeover capability when occupants are suddenly required to resume vehicle guidance.
Innovation Solution
A method that detects the sleep state of vehicle occupants using sensors and generates takeover capability information, influencing their state to maintain a minimum level of alertness through route planning and targeted interventions, ensuring they remain in a lighter sleep phase to ensure timely and safe vehicle control.

1Reliability
If the assistance system actively influences the occupant's sleep state to maintain minimum takeover capability, then safety is improved, but the system complexity increases
Solution Approach 1:
The assistance system integrates multiple functions into a single coordinated mechanism: it detects the occupant's sleep state, determines appropriate sleep depth levels, and controls stimulation devices to maintain minimum takeover capability. This multi-functional integration reduces the need for separate dedicated systems for each function.
Solution Approach 2:
The system uses the occupant's own physiological responses and sleep patterns to automatically adjust the sleep depth control. The detection device monitors the occupant's state, and the assistance system autonomously adjusts stimulation parameters without requiring external intervention or complex manual control mechanisms.

AI summary
An assistance system influences an asleep and/or awake state of a vehicle occupant to at least temporarily take over a vehicle guidance function by detecting the asleep and/or awake state of the vehicle occupant using a detection device to generate takeover capability information, detecting, receiving, and/or generating destination arrival information, at least temporarily influencing the asleep and/or awake state of the vehicle occupant by an influencing device, such that there is a defined minimum takeover capability of the vehicle occupant to take over a vehicle guidance function for the vehicle occupant for at least a portion of the journey and/or travel time at least over a portion of the journey and/or travel time.
