Solution Overview

Problem

Existing credit systems for vehicles do not incentivize green driving behavior for vehicles with internal combustion engines or consider the manner in which green vehicles are driven, leading to inefficiencies in rewarding environmentally friendly driving practices.

Innovation Solution

An authentication and verification module that includes processors, network interface hardware, auxiliary sensors, and memory modules to compare diagnostic signals from a vehicle's onboard diagnostics module with verification signals from auxiliary sensors, transmitting a driving behavior communication to a remote server when the signals are within a predetermined threshold, thereby incentivizing green driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing credit systems are used to reward green driving, then manufacturers receive credit for producing zero emission cars, but the system does not incentivize green driving behavior for vehicles with internal combustion engines

Engineering Contradiction:

Improveincentive effectivenessVSAvoidapplicability to different vehicle types

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system is designed to universally apply to all vehicle types including both zero emission cars and vehicles with internal combustion engines. The authentication module can verify green driving behavior across different vehicle platforms, making the credit system adaptable and versatile rather than limited to specific vehicle categories.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements feedback mechanisms where driving behavior is continuously monitored and verified through authentication modules. This feedback loop allows the system to recognize and reward green driving behaviors in real-time, making the incentive system more effective and responsive to actual driving patterns rather than relying on static vehicle classifications.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If green vehicles are treated the same as conventional vehicles, then simple credit allocation is maintained, but the manner in which green vehicles are driven is not considered

Engineering Contradiction:

Improvesystem simplicityVSAvoiddriving behavior verification accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

An authentication module is introduced as an intermediary between the vehicle's onboard diagnostics and the credit allocation system. This intermediary component verifies driving behavior by comparing diagnostic signals with expected green driving patterns, adding measurement precision without fundamentally complicating the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual or administrative verification methods with automated electronic verification through authentication modules. This substitution maintains system simplicity from the user perspective while significantly improving the precision and accuracy of driving behavior measurement and verification.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If driving behavior verification is implemented, then accurate incentive allocation is achieved, but additional sensors and authentication modules are required

Engineering Contradiction:

Improveincentive allocation accuracyVSAvoidsystem component count

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authentication module is designed to perform multiple functions: it authenticates vehicle identity, verifies driving behavior, compares diagnostic signals, and validates incentive eligibility. By consolidating these functions into a single multi-functional component, the system achieves reliable incentive allocation without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the authentication and verification functions into a unified module that works integrated with the existing onboard diagnostics system. This combining approach reduces the number of separate components needed while maintaining high reliability in incentive allocation through comprehensive verification.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An authentication and verification module for incentivizing green driving includes one or more processors, network interface hardware configured to communicate with a remote server, one or more auxiliary sensors for outputting a verification signal, and one or more memory modules. The one or more memory modules store logic that, cause the authentication and verification module to: receive a diagnostic signal from an onboard diagnostics module of a vehicle, receive the verification signal from the one or more auxiliary sensors, compare the diagnostic signal with the verification signal, and transmit a driving behavior communication with the network interface hardware to the remote server when the verification signal and the diagnostic signal are within a predetermined threshold from one another. The authenticated driving behavior can then be used to calculate and assign appropriate incentives to the vehicle driver.
