Driving Evaluation Display System for Individual and Total Metrics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving skill diagnosis systems fail to effectively display evaluation values for individual diagnosis items, making it difficult to compare results and identify areas for improvement.
Innovation Solution
An information processing device that calculates and displays individual evaluation values and a total evaluation value for driving-related calculation items, allowing for easy comparison and providing relevant information to encourage improvement or praise based on these values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only the total evaluation value is displayed, then the display is simple and easy to understand, but it is difficult to grasp the evaluation status of each individual diagnosis item
Solution Approach 1:
The patent divides the total evaluation value into individual evaluation values for each diagnosis item. The display shows both the total evaluation value and breaks it down into components for each calculation item (e.g., acceleration, steering, braking), allowing users to understand both the overall result and specific areas needing improvement without overwhelming the display.
2Loss of information
If individual evaluation values for each diagnosis item are displayed, then detailed information is provided, but the display becomes complex and difficult to comprehend at a glance
Solution Approach 1:
The patent extracts and highlights only the most important information elements: the total evaluation value is prominently displayed, with individual diagnosis item evaluation values presented as supporting details. This extraction approach prevents information overload while maintaining comprehensiveness.
Solution Approach 2:
The patent applies different display characteristics to different parts of the evaluation information. The total evaluation value receives prominent display treatment, while individual diagnosis item values are presented with varying visual weights based on their importance and the driver's performance level, creating a hierarchical information structure.
3Device complexity
If evaluation values are displayed without context, then the display is straightforward, but it is difficult to determine whether the diagnosis result is good or bad
Solution Approach 1:
The patent implements feedback by displaying reference information such as average evaluation values, target values, or improvement suggestions alongside the actual evaluation values. This allows drivers to immediately assess whether their performance is good or bad by comparing against references, transforming raw data into actionable feedback.

AI summary
An information processing device includes: a decision unit that decides upper limits of respective individual evaluation values for a plurality of calculation items such that a total of the upper limits is a previously determined value, the individual evaluation values being relevant to driving of a driver, the calculation items being calculation items for which the individual evaluation values are calculated; an acquisition unit that acquires vehicle information relevant to a vehicle; a calculation unit that calculates the respective individual evaluation values for the calculation items within the upper limits decided by the decision unit, based on the vehicle information acquired by the acquisition unit; and a control unit that displays, on a display unit, the respective individual evaluation values for the calculation items that are calculated by the calculation unit and a total evaluation value that is a total of the respective individual evaluation values for the calculation items.
