Vehicle Interior Attention Sensing for Personalized Function Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack the ability to automatically detect and respond to the presence of temporary items and the attention level of occupants, limiting the provision of personalized and efficient comfort functions, particularly in autonomous driving scenarios.
Innovation Solution
A method that utilizes sensor devices to detect the presence of temporary items and the attention level of occupants, triggering vehicle functions such as adjustments, notifications, and illuminations based on the detected items and their classification, and the occupant's attention direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomous or largely autonomous driving is implemented, then additional comfort functions for users can be provided, but the variability in component arrangement in the vehicle interior increases
Solution Approach 1:
The patent implements dynamic adjustment of vehicle components (seats, steering wheels, pedals) based on real-time detection of occupant position and attention level. The system continuously adapts component positions and functions according to detected operator events and useful item locations, transforming static vehicle interiors into dynamic, responsive environments that accommodate varying comfort needs without permanent structural changes
Solution Approach 2:
The system enables automatic self-adjustment of vehicle functions through sensor-based detection of occupant presence, position, and attention levels. The control system autonomously triggers appropriate functions (seat adjustment, climate control, notification routing) without requiring manual user input, allowing the vehicle to serve its occupants' comfort needs automatically while managing component variability
2Ease of operation
If sensor devices detect useful items and operator events, then automatic function triggering improves user comfort, but the system complexity and detection requirements increase
Solution Approach 1:
The patent employs sensor devices with multiple detection capabilities (presence detection, position detection, attention level detection) that serve various functions within a single integrated system. The same sensor infrastructure supports diverse operator events and useful item detections, reducing the need for separate specialized sensors for each function while maintaining comprehensive monitoring capabilities
Solution Approach 2:
The control system acts as an intermediary that processes sensor data and translates detected operator events and useful item locations into appropriate function triggers. This intermediary layer simplifies the overall system architecture by centralizing the interpretation and decision-making logic, reducing the complexity burden on individual sensor devices while enabling sophisticated automatic function triggering
3Adaptability or versatility
If the system detects attention level of occupants, then personalized notifications can be directed to appropriate occupants, but the measurement and detection precision requirements increase
Solution Approach 1:
The system applies different detection thresholds and attention level criteria to different occupants and different vehicle zones. Rather than using a single uniform precision standard, the system adapts its measurement requirements to local contexts (driver vs. passenger, different seating positions, different times of day), allowing personalized notification routing while managing detection precision requirements through localized adaptation

AI summary
It is provided a method for function control on a vehicle, the method having at least the following steps: detecting a useful item in the surroundings of the vehicle or in an interior of the vehicle by at least one sensor device of the vehicle, and triggering at least one function on the vehicle depending on at least one detected operator event and the detection of the useful item. The at least one operator event comprises a presence of at least one person in the interior, and a level of attention of the at least one person directed towards a portion of the interior, on which the at least one triggered function is dependent, being detected by the at least one sensor device.
