Solution Overview

Problem

Existing fuel-saving driving evaluation systems fail to account for the driver's skill level, leading to excessive stress and reduced motivation for beginners and inadequate challenge for skilled drivers, as they are based on a single evaluation standard.

Innovation Solution

A fuel-saving driving evaluation system that includes engine speed, vehicle speed, and fuel flow-rate measuring devices, along with a controller that adjusts evaluation standards and target values based on a selected mode (skilled or beginner) using a difficulty level constant, allowing for multiple evaluation modes and adaptive feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single evaluation standard is used for all drivers, then the evaluation system is simple to implement, but skilled drivers find it too easy while beginners find it too difficult, reducing motivation for both groups

Engineering Contradiction:

Improveadaptability to different driver skill levelsVSAvoidcomplexity of evaluation system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The evaluation system dynamically adjusts the evaluation standard based on the driver's skill level. The controller selects between a first evaluation standard for skilled drivers and a second evaluation standard for beginners, making the system adaptable rather than static. This resolves the contradiction by allowing the system to change its evaluation criteria according to the driver's category.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different evaluation standards are applied to different groups of drivers based on their skill level. Skilled drivers receive one type of evaluation while beginners receive another, allowing each group to be evaluated by appropriate criteria. This local differentiation resolves the contradiction between adaptability and complexity.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If a strict evaluation standard is applied to beginners, then evaluation precision is improved, but driver stress increases and motivation to improve fuel-saving driving skills decreases

Engineering Contradiction:

Improveprecision of fuel-saving driving evaluationVSAvoiddriver stress

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system applies different evaluation standards to different driver groups. Beginners are evaluated using a second standard that is less strict and more encouraging, while skilled drivers receive the first standard. This local differentiation maintains evaluation precision for each group while reducing stress for beginners.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The evaluation standard dynamically adapts to the driver's skill level. The controller determines whether the driver is a beginner or skilled based on input signals and selects the appropriate evaluation standard accordingly. This dynamic adjustment ensures precision while avoiding excessive stress on beginners.

Inventive Principle:

Principle #15Dynamics

3Productivity

If an easy evaluation standard is applied to skilled drivers, then driver motivation is maintained, but evaluation precision decreases and cannot adequately challenge advanced drivers

Engineering Contradiction:

Improvedriver motivation to enforce fuel-saving drivingVSAvoidprecision of fuel-saving driving evaluation

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system applies different evaluation standards to different driver groups. Skilled drivers are evaluated using the first standard which provides adequate challenge and maintains motivation, while beginners receive the second standard. This local differentiation ensures both motivation and precision are maintained for each group.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The evaluation standard dynamically adjusts based on driver skill level. The controller receives skill level information and selects the appropriate standard, ensuring skilled drivers receive challenging evaluation while maintaining motivation. This dynamic approach resolves the contradiction between motivation and precision.

Inventive Principle:

Principle #15Dynamics

AI summary

Disclosed is a fuel-saving driving evaluation system which provides a driver with advice suitable for the driver based on fuel-saving driving evaluation standards which correspond to the fuel-saving driving proficiency level of the driver, so that the driver is relaxed and the fuel-saving driving skill of the driver is gradually improved. The fuel-saving driving evaluation system is comprised of an engine speed measuring device, a vehicle speed measuring device, a fuel flow measuring device, and a control device. The control device has a function to store several kinds of standard values and target values of parameters (driving operation parameters) for evaluating the fuel-saving driving level in the vehicle to be evaluated, and a function to determine the standard values and the target values of the parameters based on control signals sent from outside of the control device.
