Solution Overview

Problem

Current Advanced Driver Assist Systems (ADAS) do not effectively account for the driver state of surrounding vehicles, which can impact driving conditions, leading to potential safety hazards due to drowsy drivers.

Innovation Solution

A vehicle system that communicates with surrounding vehicles to detect driver drowsiness and adjust its speed and direction to avoid them, using a communicator, detector, driving assistance module, and controller to receive and analyze driver state information, determine drowsiness, and control the vehicle's speed and direction accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vehicle uses Advanced Driver Assist Systems to monitor driver status and surrounding environment, then driving convenience and information provision are improved, but the system cannot effectively respond to drowsy drivers in surrounding vehicles, creating a safety hazard

Engineering Contradiction:
Improvedriving safetyVSAvoiddriver state information of surrounding vehicle
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent uses communication modules as intermediaries to transmit driver state information from surrounding vehicles to the host vehicle's controller. This allows the host vehicle to obtain information about drowsy drivers in surrounding vehicles without directly monitoring them, resolving the information loss problem while improving safety through V2V communication.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary detection and analysis of driver state information from surrounding vehicles before actual collision risks arise. By continuously receiving and analyzing driver state data, the system can predict potential hazards from drowsy drivers and take preventive actions, improving reliability through advance warning.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the vehicle continuously receives and analyzes driver state information from surrounding vehicles to determine drowsiness, then driving safety is improved, but communication energy and processing time are increased

Engineering Contradiction:
Improvedrowsiness detection accuracyVSAvoidcommunication and processing energy
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The controller periodically receives driver state information from surrounding vehicles at predetermined time intervals rather than continuously. This periodic sampling approach maintains adequate detection accuracy for identifying drowsy states while significantly reducing communication energy consumption and processing loads compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system selectively processes only the necessary driver state information parameters required for drowsiness detection, rather than analyzing all available data. This partial action approach achieves sufficient detection reliability while minimizing energy consumption and processing requirements.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If the vehicle automatically controls driving assistance module to avoid surrounding vehicles with drowsy drivers, then safety is improved, but driver autonomy and control precision may be reduced

Engineering Contradiction:
Improvecollision avoidance capabilityVSAvoiddriver control authority
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system provides feedback to the driver by notifying them of detected drowsy drivers in surrounding vehicles and the automated avoidance actions taken. This feedback mechanism maintains driver awareness and control authority while enabling automated safety interventions, resolving the contradiction between autonomous protection and driver autonomy.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies preliminary anti-action by automatically adjusting driving parameters to prevent collision with drowsy drivers before a hazardous situation develops. The controller proactively controls the driving assistance module to maintain safe distances or change lanes, preventing potential accidents while preserving driver choice through notification.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

A vehicle may include a communicator configured to receive driver state information from a surrounding vehicle, a detector configured to obtain driving information related to surrounding vehicle, a driving assistance module configured to control at least one of a driving speed or a driving direction and a controller configured to determine whether a driver of the surrounding vehicle is in drowsiness state based on whether the received driver state information satisfies a predetermined condition and if the driver of the surrounding vehicle is determined as drowsiness state, control the driving assistance module to avoid the surrounding vehicle.
