Vehicle Display Control for Poor Energy-Efficiency Driving Frequency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for vehicles, such as those disclosed in JP 2010-41750 A, struggle to effectively track and communicate to managers the frequency of driving with poor energy consumption efficiency performed by drivers, making it difficult to provide timely guidance for improvement.
Innovation Solution
A display control device that acquires vehicle information, determines if the vehicle has traveled with poor energy consumption efficiency within a predetermined time from specific driving operations, and displays the number of times this occurs per unit time, allowing drivers to understand their energy consumption efficiency and enabling managers to provide targeted guidance.

Engineering Contradiction Analysis
1Measurement precision
If detailed driving operation data is collected and analyzed, then energy consumption efficiency measurement precision is improved, but device complexity increases
Solution Approach 1:
The vehicle's existing control units and sensors self-generate the necessary driving operation data without requiring additional dedicated measurement devices. The display control device utilizes already-collected vehicle data (accelerator operations, brake operations, engine data) to perform energy consumption efficiency analysis, thereby improving measurement precision without significantly increasing device complexity.

AI summary
An acquisition unit that acquires vehicle information related to a vehicle state of a vehicle; a determination unit that determines whether the vehicle has traveled in a state in which energy consumption efficiency of the vehicle is poor within a predetermined time from a predetermined driving operation of the vehicle based on the vehicle information acquired by the acquisition unit; and a display control unit that causes a display unit to display the number of times of traveling in the state per unit time within the predetermined time from the predetermined driving operation, the traveling being determined by the determination unit, are included.
