In-Vehicle Device Driver Feeling Estimation Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle systems fail to provide effective driving guidance that efficiently improves a driver's skills by not considering the driver's psychological state during vehicle operation.
Innovation Solution
An in-vehicle device that selects ideal traveling information based on the driver's estimated feeling, determines differences between detected and ideal traveling states, and notifies the driver of deviations, using sensors and a server to provide personalized driving guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If driving guidance is provided without considering driver's psychological state, then the system complexity is reduced, but the effectiveness of skill improvement deteriorates
Solution Approach 1:
The system performs preliminary estimation of the driver's psychological state (feeling) before providing driving guidance. The feeling estimation unit assesses the driver's emotional condition in advance, allowing the selection unit to choose appropriate guidance content that matches the driver's current state, thereby improving skill development effectiveness without adding excessive complexity during active driving
Solution Approach 2:
The system dynamically adapts the driving guidance content based on the driver's changing psychological state. By continuously monitoring the driver's feeling and adjusting the guidance level accordingly, the system optimizes skill improvement effectiveness while maintaining manageable complexity through adaptive rather than static guidance structures
2Adaptability or versatility
If multiple pieces of ideal traveling information are provided for different skill levels, then the adaptability to driver skill levels is improved, but the device complexity increases
Solution Approach 1:
Multiple pieces of ideal traveling information are prepared in advance for different skill levels (first, second, and third skill levels). The selection unit pre-organizes this information so that when driving guidance is needed, the appropriate pre-prepared information can be quickly selected based on the driver's current skill level, avoiding the complexity of generating multiple information sets in real-time
Solution Approach 2:
Different pieces of ideal traveling information are tailored to specific skill levels, with each level receiving guidance appropriate to its capabilities. The system provides specialized information for each skill level rather than a generic approach, improving adaptability while managing complexity through targeted rather than universal information delivery
3Measurement precision
If real-time determination of traveling state differences is performed, then the measurement precision of driving deviations is improved, but the processing time increases
Solution Approach 1:
The determination unit focuses on determining differences only for specific items where deviations from ideal traveling information are detected, rather than continuously analyzing all possible parameters. This partial action approach maintains measurement precision for critical deviations while reducing overall processing time by avoiding exhaustive analysis of every traveling state parameter
