Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving evaluation systems fail to accurately assess driving skills during lane changes by considering near-miss scenarios, leading to potential underestimation of collision risks.
Innovation Solution
A driving evaluation device that includes a lane change detector, behavior detector, and evaluator to assess driving skills by detecting changes in the behavior of surrounding vehicles after a lane change, adjusting the evaluation value based on these changes to reflect increased collision risk.

Engineering Contradiction Analysis
1Measurement precision
If driving evaluation systems only consider traditional driving parameters, then the evaluation process remains simple, but the accuracy of assessing driving skills during lane changes is insufficient
Solution Approach 1:
The system continuously monitors the behavior of surrounding vehicles during lane changes and uses this feedback to adjust the driving skill evaluation. The evaluator receives real-time information about other vehicles' actions (acceleration, deceleration, steering changes) and modifies the evaluation value accordingly, creating a closed-loop assessment that improves accuracy without requiring completely new evaluation infrastructure.
Solution Approach 2:
The evaluation system integrates multiple functions into a unified framework: it continues to monitor traditional driving parameters while simultaneously detecting lane change behavior and surrounding vehicle responses. This multi-functional approach allows the system to assess driving skills comprehensively during lane changes without requiring separate dedicated systems, thus improving accuracy while controlling complexity.
2Reliability
If the system detects and responds to changes in surrounding vehicle behavior, then the evaluation of collision risk improves, but the processing time and computational load increase
Solution Approach 1:
The system pre-establishes evaluation criteria and thresholds for detecting changes in surrounding vehicle behavior. By having these criteria ready in advance, the evaluator can quickly compare real-time data against predetermined standards during lane changes, reducing the need for complex real-time calculations and minimizing processing delays while maintaining accurate collision risk assessment.
Solution Approach 2:
The evaluation system dynamically adjusts its monitoring intensity based on the driving context. During lane changes, the system activates enhanced detection of surrounding vehicle behavior, while during normal driving it operates in a lighter mode. This dynamic activation allows the system to provide accurate collision risk assessment when needed without continuously consuming excessive computational resources.

AI summary
A driving evaluation device includes: a lane change detector that detects a start of a lane change by a vehicle; a behavior detector that detects behavior of an other vehicle in a vicinity of the vehicle; and an evaluator that calculates an evaluation value of driving skills of a driver of the vehicle, according to an operating history of the vehicle. The evaluator decreases the evaluation value, when a change in the behavior is detected after the start of the lane change is detected.
