Vehicle Driving Pattern Display for Excess Fuel Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for displaying vehicle driving patterns to optimize fuel efficiency do not provide comprehensive information on excess fuel consumption and time savings, limiting drivers' ability to make informed decisions about their driving habits.
Innovation Solution
A method and system that calculate and display excess fuel consumption based on actual versus reference speeds, including monetary and environmental impact, and provide feedback on time reduction, using a central processing unit and display unit to present this information to drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers receive basic fuel efficiency indicators, then they can identify suboptimal driving patterns, but they lack comprehensive information to make well-founded decisions about driving pattern adjustments
Solution Approach 1:
The system segments fuel consumption information into distinct components: actual fuel consumption, reference fuel consumption, excess fuel consumption, and time savings. This segmentation allows drivers to understand specific aspects of their driving efficiency without overwhelming them with a single complex metric, resolving the contradiction by providing comprehensive information in a structured, digestible format.
Solution Approach 2:
The system adds a temporal dimension to fuel efficiency information by simultaneously displaying both excess fuel consumption and time savings. This multi-dimensional presentation (combining fuel cost and time cost dimensions) enables drivers to make well-founded decisions by considering trade-offs across different dimensions, rather than providing only a single-dimensional fuel efficiency metric.
2Loss of information
If the system displays only fuel consumption data, then it maintains simplicity, but it does not provide comprehensive feedback on the trade-off between time savings and fuel efficiency
Solution Approach 1:
The system merges two separate pieces of information - excess fuel consumption and time savings - into a unified display that presents both metrics simultaneously. This combining allows drivers to comprehensively evaluate the trade-off between time and fuel efficiency in a single view, providing complete feedback without requiring separate displays or complex processing of multiple independent data streams.
Solution Approach 2:
The system implements a feedback mechanism that provides drivers with immediate information about the consequences of their driving patterns. By displaying both the negative impact (excess fuel consumption) and the positive benefit (time savings), the system enables drivers to make informed decisions by seeing the complete feedback loop between their driving behavior and its multi-faceted consequences.
3Loss of information
If the system provides detailed information on driving patterns, then drivers can make informed decisions, but the instrument panel becomes cluttered and harder to read
Solution Approach 1:
The system extracts only the most critical pieces of information needed for driving pattern optimization - specifically excess fuel consumption and time savings - and displays them prominently. By selecting and displaying only these key metrics rather than all available data, the system maintains high information quality for decision-making while keeping the display clean and readable by excluding less relevant details.

AI summary
The invention relates to a method for displaying a representation of a driving pattern of a vehicle (2), said method comprising: determining said driving pattern in the form of a condition involving excess fuel consumption of said vehicle (2); and displaying a representation of said excess fuel consumption on a display unit (9) in said vehicle (2). According to the invention, the method further comprises: providing first input data related to an actual speed (v1) of said vehicle (2) travelling along a route (1 a, 1 b, 1 c); providing second input data related to a reference speed (v2) for said route (1 a, 1 b, 1 c); calculating, based on said first and second input data, a measure of said excess fuel consumption as a result of said actual speed (v1) exceeding said reference speed (v2); and presenting, on said display unit (9), said representation of the excess fuel consumption. The invention also relates to a system (4) for displaying a representation of a driving pattern of a vehicle (2).
