Solution Overview

Problem

Existing systems fail to effectively assess and improve a driver's anticipation when queuing, as they do not adequately consider the behavior of surrounding vehicles, leading to increased vehicle wear and fuel consumption due to frequent braking and acceleration.

Innovation Solution

A system and method that determine and compare vehicle parameters such as speed, acceleration, and deceleration of both the host vehicle and surrounding vehicles to assess the driver's anticipation, generating an assessment signal based on predetermined rules, which can be used to provide feedback for improved driving behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a driver drives reactively without anticipation in queue conditions, then the driving behavior is simpler to control, but fuel consumption increases and vehicle wear increases due to frequent braking and acceleration

Engineering Contradiction:
Improvefuel consumptionVSAvoiddriving behavior control
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system continuously monitors the host vehicle's speed, acceleration, and deceleration patterns, compares them with surrounding vehicles, and provides assessment feedback to the driver. This feedback loop enables the driver to adjust their driving behavior to achieve better fuel efficiency and reduced vehicle wear while maintaining control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual driving judgment with an automated electronic assessment system that uses sensors, processors, and communication modules to objectively evaluate driving behavior. This substitution provides precise measurement and feedback that is difficult to achieve through manual driving techniques alone.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If existing assessment systems evaluate driver behavior in isolation, then the assessment process is simpler, but the assessment accuracy decreases because it does not account for surrounding vehicle behavior

Engineering Contradiction:
Improveassessment accuracyVSAvoidassessment system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system merges data from multiple sources including the host vehicle's own performance metrics with data from surrounding vehicles detected by radar and communication systems. This combination creates a comprehensive assessment that accurately reflects queue driving conditions while accounting for the behavior of vehicles ahead and behind.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The assessment system is designed to evaluate multiple aspects of driving behavior simultaneously - speed maintenance, acceleration patterns, deceleration patterns, and comparison with surrounding vehicles. This multi-functional approach provides a comprehensive accuracy measure without requiring separate assessment systems for each parameter.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If the system monitors multiple vehicle parameters continuously, then the assessment of driver anticipation becomes more accurate, but the data processing complexity and energy consumption increase

Engineering Contradiction:
Improvedriver anticipation assessmentVSAvoiddata processing energy
Core Design Contradiction:
Measurement precisionVSUse of energy by stationary object

Solution Approach 1:

The system extracts only the most relevant parameters for assessing driver anticipation - primarily speed, acceleration, and deceleration patterns - from the available data. By focusing on these key parameters rather than processing all possible vehicle data, the system maintains high assessment accuracy while minimizing energy consumption for data processing.

Inventive Principle:
Principle #2Taking out (Extraction)
