Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers transitioning to hybrid vehicles often maintain suboptimal driving habits due to unfamiliarity with the hybrid vehicle features, leading to inefficient use and potential safety issues.
Innovation Solution
A computer-implemented method and system that acquires an electric driving ratio or fuel driving ratio over a past travel distance and provides feedback to users, encouraging more efficient and safe driving practices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If drivers maintain old driving habits in hybrid vehicles, then driving simplicity is preserved, but fuel efficiency deteriorates and electric motor usage is suboptimal
Solution Approach 1:
The system provides feedback to the driver about the electric driving ratio and fuel economy, enabling the driver to adjust driving behavior to optimize energy usage while maintaining ease of operation through intuitive information presentation
2Use of energy by moving object
If feedback is provided to improve electric driving ratio, then fuel efficiency is improved, but information processing complexity increases
Solution Approach 1:
The system calculates the electric driving ratio based on existing sensor data and provides feedback through the display unit, improving energy efficiency without requiring complex additional hardware or processing systems
Solution Approach 2:
The system uses existing vehicle data (motor usage, distance traveled) to automatically calculate and present the electric driving ratio, eliminating the need for additional measurement devices or complex external processing
