In-Cabin Driving Evaluation Display for Glanceable Score Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for evaluating driving skills do not effectively convey evaluation results to drivers, making it difficult for them to comprehend their performance simply by glancing at the display.
Innovation Solution
A display control device and method that acquires and displays driving evaluation items, visually representing the remaining permissible times for each item, using symbols or color changes to highlight critical metrics, and calculates a driving score to simplify the understanding of evaluation results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If detailed driving evaluation data is displayed, then comprehensive evaluation information is provided, but driver comprehension becomes difficult and time-consuming
Solution Approach 1:
The display is segmented into multiple regions: a first display region showing the overall driving evaluation result (pass/fail) and a second display region showing detailed evaluation items. This segmentation allows drivers to quickly grasp the main result while providing access to detailed information when needed, resolving the contradiction between information completeness and comprehension ease.
Solution Approach 2:
The critical evaluation result (pass/fail determination) is extracted and displayed prominently in the first display region, separate from the detailed evaluation items. This extraction allows drivers to immediately understand the overall evaluation outcome without being overwhelmed by detailed data, while the second region remains available for those who need to review specific evaluation criteria.
2Loss of information
If multiple evaluation items are displayed simultaneously, then comprehensive feedback is provided, but visual clutter increases and key information becomes hard to identify
Solution Approach 1:
Different regions of the display are assigned different qualities and functions: the first display region uses simplified, high-contrast visualization for the overall result, while the second display region presents detailed evaluation items in a structured format. This local differentiation allows comprehensive information to be presented without creating visual clutter, as each region is optimized for its specific purpose.
3Measurement precision
If numerical evaluation data is displayed, then precise measurement is provided, but driver understanding becomes less intuitive
Solution Approach 1:
The system uses color changes to represent evaluation results intuitively: green indicates passing evaluation items, red indicates failing items, and yellow indicates warning levels. This color-coded system maintains precise measurement information while making the evaluation results immediately understandable to drivers without requiring numerical analysis.

AI summary
A display control device (10) includes one or more processors configured to: acquire information regarding a plurality of driving evaluation items set in advance; count, as the number of times of measurement, the number of times that at least one of a vehicle state and a driving state meets each of the driving evaluation items while a driver is driving a vehicle; display the driving evaluation items in a display region in a vehicle cabin; and visually display information relating to the remaining number of times that is a difference between the permissible number of times set for each of the driving evaluation items and the number of times of measurement.
