Vehicle Function Adaptation Using Contextual Driver Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adaptive vehicle systems face challenges in accurately adapting to user preferences and safety needs due to potential negative reactions and unsuitable adaptations from unintentional or incidental user feedback, leading to inefficient processing and potential counter-productive changes in operation modes.
Innovation Solution
A method that filters user reactions by determining feedback criteria and context to distinguish intentional feedback from non-indicative behavior, allowing for more accurate and reliable adaptation of vehicle system operations based on user preferences and safety considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle system automatically changes operation mode based on driver behavior, then the system adapts to driver preferences and improves safety compliance, but the driver may experience negative reactions such as irritation or stress
Solution Approach 1:
The system implements feedback by monitoring driver reactions to automatic operation mode changes and using this information to adjust future adaptations. The control unit determines whether the driver's behavior fulfills feedback criteria associated with user reaction types, allowing the system to learn from driver responses and reduce irritating automatic changes over time
Solution Approach 2:
The system dynamically adjusts its adaptation behavior based on detected driver reactions. When negative reactions are detected through feedback criteria evaluation, the system modifies its operation mode change strategy, making the adaptation process flexible and responsive to driver comfort rather than rigid and predetermined
2Loss of information
If the vehicle system monitors all user behavior data for adaptation, then comprehensive user preferences can be captured, but the processing load increases and non-indicative behavior may lead to unsuitable adaptations
Solution Approach 1:
The system extracts only the relevant information from comprehensive behavior data by evaluating feedback criteria. Instead of processing all behavior data equally, the control unit identifies and processes only those behavior patterns that fulfill specific feedback criteria associated with intentional user reactions, filtering out non-indicative behavior
Solution Approach 2:
The system applies different processing quality to different types of behavior data. Intentional feedback that fulfills feedback criteria receives detailed processing for adaptation decisions, while non-indicative behavior is filtered out or processed with lower priority, optimizing resource allocation across different data types
3Ease of operation
If the vehicle system automatically adapts functionalities based on driver behavior patterns, then user needs are better met, but the system may make counter-productive changes that reduce safety or usability
Solution Approach 1:
The system uses feedback criteria evaluation to verify that automatic adaptations produce the intended positive effects. By monitoring whether driver behavior changes align with safety compliance goals and user preferences, the system can detect counter-productive adaptations and adjust its adaptation strategy to maintain reliability
Solution Approach 2:
The system takes preliminary anti-action by evaluating feedback plausibility conditions before implementing adaptations. The control unit determines whether behavior fulfills feedback criteria and whether feedback plausibility conditions are met, preventing potentially harmful adaptations from being applied in the first place rather than correcting them after the fact

AI summary
A method (100; 400) of operating a vehicle system (210) comprises changing (110; 410 - 416) an operation mode of at least one functionality (230) of a vehicle system (210), receiving (120; 420) behavior data indicative of a behavior of a user (D) of the vehicle system (210), and determining (130; 430) a context of the vehicle system (210) coinciding with the behavior of the user (D). The method further comprises determining (140; 440) whether the behavior of the user (D) fulfills at least one feedback criterion with respect to the changed operation mode of the at least one functionality (230), wherein the feedback criterion is associated with at least one of one or more user reaction types, determining (150; 450), based on the determined context, whether a feedback plausibility condition is fulfilled with respect to the behavior of the user (D) and the at least one user reaction type, and, when the feedback plausibility condition is fulfilled, operating (160; 460 - 470) the vehicle system (210) with respect to the at least one functionality (230) based at least partially on the at least one user reaction type.
