Vehicle Driving Skill Evaluation With Threshold-Based Score Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional evaluation systems for vehicle driving skills require drivers to enhance both vehicle stability and turning performance scores equally, leading to inflexibility in skill development, as both scores are always additive elements, making it difficult to selectively focus on improving either score.
Innovation Solution
An evaluation program that uses conversion information to determine an overall evaluation result, where if the first evaluation result is lower than a threshold, the second evaluation result is a point-deduction element, and if higher, it is a point-addition element, allowing for flexible promotion or suppression of the second evaluation result based on the first result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If both vehicle stability score and turning performance score are always additive elements, then comprehensive skill evaluation is achieved, but flexibility in skill development is reduced
Solution Approach 1:
The patent applies dynamics by making the evaluation system adaptable and changeable. The conversion information dynamically adjusts the weight or contribution of the second evaluation result based on the first evaluation result. When the first result exceeds a threshold, the second result becomes an additive element; when below the threshold, it may become a subtractive element or have reduced weight. This dynamic adjustment allows the system to maintain comprehensive evaluation while providing flexible development paths for different skill levels.
Solution Approach 2:
The patent changes parameters by introducing conversion information that modifies how evaluation results are combined. The conversion information contains threshold values and conversion rules that transform the relationship between evaluation results. By changing the parameter of result combination from fixed additive to conditional (additive/subtractive based on thresholds), the system achieves both comprehensive evaluation and developmental flexibility.
2Stability of the object's composition
If drivers are required to enhance both vehicle stability and turning performance scores equally, then balanced skill development is promoted, but selective focus on specific skills is prevented
Solution Approach 1:
The patent applies local quality by allowing different evaluation criteria to apply to different skill levels or situations. The conversion information creates different evaluation regimes: when the first evaluation result is above the threshold, one set of rules applies (second result is additive); when below the threshold, different rules apply (second result may be subtractive or have reduced weight). This localized evaluation approach enables drivers to focus selectively on specific skills while maintaining overall balanced development.
Solution Approach 2:
The system dynamically adjusts the evaluation framework based on the first evaluation result. The conversion information enables the system to switch between different evaluation modes, allowing drivers to receive targeted feedback that promotes selective skill focus when needed while maintaining balanced development opportunities when appropriate.
3Device complexity
If the overall evaluation result is always a linear sum of component scores, then simplicity in calculation is maintained, but inability to suppress certain scores is caused
Solution Approach 1:
The patent changes the parameter of result combination from fixed linear summation to conditional combination using conversion information. The conversion information introduces threshold-based logic that determines whether the second evaluation result is added, subtracted, or given reduced weight. This parameter change maintains relative calculation simplicity while enabling score suppression when the first result falls below the threshold, thus resolving the contradiction between simplicity and adaptability.

AI summary
An evaluation program causes a computer to perform steps of obtaining a vehicle stability score Sv on vehicle driving skills based on measured data, obtaining a turning performance score Tv on the vehicle driving skills based on the measured data, obtaining an overall evaluation result on the vehicle driving skills based on the vehicle stability score Sv and the turning performance score Tv using conversion information, and conveying the overall evaluation result to an output unit. The conversion information defines the overall evaluation result in such a way that the overall evaluation result decreases as the turning performance score Tv increases if the vehicle stability score Sv is lower than a threshold and in such a way that the overall evaluation result increases as the turning performance score Tv increases if the vehicle stability score Sv is higher than the threshold.
