Vehicle Menu Display Based on Driving-State Usage Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information apparatuses do not account for vehicle state (driving vs. stopped) when proposing frequently used functions, limiting user operability and convenience.
Innovation Solution
An information apparatus that detects vehicle state and displays menus with operation items based on their frequency of use during motion or stop, using a vehicle state detection unit, display control unit, input reception unit, execution unit, and identification unit to classify and prioritize operation items by frequency in different states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the quick menu displays functions specified by the manufacturer, then the device complexity is reduced and ease of operation is improved, but the adaptability deteriorates because users cannot register frequently used functions
Solution Approach 1:
The system automatically analyzes operation history to identify frequently used functions and presents them to users for registration in the quick menu, eliminating the need for manual configuration while enabling user-specific customization
Solution Approach 2:
The system continuously monitors and analyzes user operation patterns, using this feedback to dynamically update and recommend functions for the quick menu, thereby adapting to changing user needs over time
2Adaptability or versatility
If the system presents habitual uses automatically detected from driving history, then the adaptability is improved, but the reliability deteriorates because vehicle state context is not considered
Solution Approach 1:
The system segments operation history analysis by vehicle state (motion/stopped), creating state-specific frequency statistics that reflect actual usage patterns in relevant contexts, thereby improving the reliability of function recommendations
Solution Approach 2:
The system dynamically adjusts the quick menu content based on current vehicle state, switching between functions frequently used during motion and functions frequently used when stopped, making the menu contextually relevant and reliable
3Adaptability or versatility
If the menu displays all available operation items, then the adaptability is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The system extracts only the most frequently used operation items from the complete function set and presents them in the quick menu, reducing the number of displayed items while maintaining adaptability to user needs
Solution Approach 2:
The system pre-analyzes operation history to identify and prepare frequently used functions before the user needs them, so that when the quick menu is called, only relevant functions are displayed, reducing complexity

AI summary
A vehicle state detection unit detects whether a vehicle including an information apparatus is in motion or stopped. A display control unit displays operation items related to various functions provided by the information apparatus on a display. A function execution unit executes a function corresponding to a selected operation item. An identification unit identifies the frequency of use of each operation item by classifying the items according to whether the vehicle is in motion or stopped. The display control unit further displays on a prescribed menu screen in which some of the operation items are aggregated. On the prescribed menu screen, when the vehicle is in motion, the operation item identified as having a high frequency of use when the vehicle is in motion is displayed, and when the vehicle is stopped, the operation item identified as having a high frequency of use when the vehicle is stopped is displayed.
