Solution Overview

Problem

The increasing complexity of vehicle systems and environments contributes to driver distractions, necessitating methods and systems for generating a vehicle driver signature based on vehicle interior image data and dynamics.

Innovation Solution

A device and method for determining a driver signature by receiving current and previously classified image data, along with vehicle dynamics data, to identify the driver based on a comparison of these data types, using a processor and memory to generate a signature that confirms the driver's identity and behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If vehicle systems and environments become more complex to provide more functionality, then vehicle capabilities and features are improved, but driver distractions increase

Engineering Contradiction:

Improvevehicle capabilitiesVSAvoiddriver distractions

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors driver state through image data and vehicle dynamics, providing feedback about driver distraction levels. This enables the vehicle to detect when the driver is affected by the complex systems and environments, allowing for timely interventions to mitigate distractions.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary system (the driver signature generation system) that mediates between the complex vehicle systems and the driver. This intermediary monitors and analyzes driver behavior, creating a buffer that helps manage the interaction between the driver and the complex vehicle environment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If driver identity is accurately identified for behavior analysis, then driver behavior detection capability is improved, but driver anonymity is compromised

Engineering Contradiction:

Improvedriver identification accuracyVSAvoiddriver anonymity

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The system creates a driver signature as a data copy or representation of the driver's behavioral patterns rather than storing or processing the driver's actual identity information. This signature captures driving characteristics, postures, and behaviors while maintaining driver anonymity by not requiring direct identification of the driver.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces direct driver identification mechanisms (which would compromise anonymity) with a behavioral signature system. Instead of identifying who the driver is, the system identifies characteristic driving patterns and behaviors, substituting identity-based recognition with behavior-based recognition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
