Solution Overview

Problem

Existing driver assistance systems fail to efficiently determine a driver's ability to operate a vehicle under the influence of impairing substances, increasing the risk of accidents.

Innovation Solution

A driver assistance system that determines one or more parameters at the beginning of each driving session, creates a temporary personal profile using artificial intelligence, and evaluates this profile to assess the driver's impairment using sensors and external data sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional driver assistance systems are used, then the system structure is simple, but the ability to determine driver impairment is insufficient

Engineering Contradiction:

Solution Approach 1:

The system segments driver monitoring into multiple independent parameter measurements (eye closure duration, blink frequency, steering patterns, response time) that can be processed separately and combined for comprehensive impairment assessment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The driver assistance system performs multiple functions using integrated sensors and processors - monitoring physiological parameters, analyzing driving behavior, detecting impairment substances, and controlling vehicle operations all through a unified multi-functional platform

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

2Reliability

If continuous monitoring of driver parameters is implemented, then driver impairment can be detected accurately, but energy consumption increases

Engineering Contradiction:

Solution Approach 1:

The system implements periodic monitoring at critical intervals - continuous parameter collection during driving sessions with enhanced monitoring triggered by anomaly detection, rather than uniformly continuous high-power operation

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system creates temporary personal profiles and establishes baseline driver parameters in advance during normal driving conditions, enabling faster comparison and decision-making during critical impairment detection scenarios without requiring continuous high-power processing

Solution Approach 2:

The system implements continuous feedback loops where AI analysis results trigger real-time adjustments in monitoring intensity and parameter collection frequency, optimizing processing time based on detected anomaly severity and driver response patterns

Inventive Principle:
Principle #23Feedback

AI summary

A method comprises, at the beginning of each driving session of a vehicle, determining one or more parameters related to a driver of the vehicle, storing the one or more parameters, thereby creating a temporary personal profile for the driver, and using artificial intelligence, AI, and based on the temporary personal profile, determining whether the driver is under the influence of impairing substances.
