Vehicle Interface Control via User Preference Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interface devices require user manipulation, which can be inconvenient and pose safety concerns, especially for those unfamiliar with them, as they demand attention and effort while driving.
Innovation Solution
A vehicle system that automatically controls interface units like AVN, cluster, and HUD by generating a user preference model based on acquired vehicle state information, using a model generation unit and controller to determine optimal outputs, minimizing user interaction and attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle interface devices are operated manually according to user manipulation, then user control and customization are improved, but manipulation load and visual attention requirements increase
Solution Approach 1:
The system automatically controls vehicle interface units by acquiring vehicle state information, storing it, generating a user preference model, and controlling outputs based on the model without requiring manual user manipulation. This self-service approach eliminates the need for users to manually operate interface devices while still providing personalized control, thereby reducing manipulation load and visual attention requirements.
2Ease of operation
If automatic control based on user preference model is implemented, then manipulation load is reduced, but system complexity increases
Solution Approach 1:
The automatic control system is divided into distinct functional modules: a vehicle state information acquisition unit that collects data, a storage unit that saves the data, a model generation unit that creates the user preference model, and a controller that executes control based on the model. This segmentation allows each component to perform its specific function independently, making the overall complex system more manageable and maintainable while providing automatic control to reduce manipulation load.
3Adaptability or versatility
If multiple vehicle interface devices with various functions are added, then user convenience and functionality are improved, but manipulation complexity and safety concerns increase
Solution Approach 1:
The controller serves as a universal control unit that manages multiple different vehicle interface devices including audio video navigation systems, cluster displays, head-up displays, lighting devices, and temperature control devices. By using a single multi-functional controller that can manage various interface units through the user preference model, the system provides diverse functionality while simplifying the control architecture and reducing manipulation complexity.
