Driver-Aware Emergency Path Clearing in Traffic Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assisting drivers in clearing an emergency path in motor vehicles do not consider the driver's state, specifically their attention and viewing direction, which can lead to unsafe or inefficient path clearing.
Innovation Solution
A method and apparatus that detect a congestion situation and the driver's viewing direction to determine the need for clearing an emergency path, allowing for partially automated or fully automated vehicle control, including crossing a road boundary, only if the driver is attentive and aware of the congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated controlling is implemented to clear the emergency path without considering driver state, then the productivity of emergency path clearing is improved, but the reliability of the operation deteriorates due to potential driver unawareness and safety risks
Solution Approach 1:
The system continuously monitors the driver's viewing direction and attention state, using this feedback to dynamically adjust whether automated emergency path clearing should be activated. The control unit receives input from the viewing direction detector and only permits automated path clearing when the driver is determined to be attentive, creating a closed-loop safety mechanism that resolves the contradiction between productivity and reliability.
2Reliability
If the driver's viewing direction detection is added to the emergency path clearing system, then the reliability of the operation is improved, but the device complexity increases
Solution Approach 1:
The system employs a multi-functional control unit that integrates congestion detection, emergency path assessment, driver viewing direction analysis, and automated steering control into a single centralized component. This universal controller consolidates multiple functions that would otherwise require separate dedicated systems, thereby improving reliability through comprehensive monitoring while minimizing the increase in device complexity through functional integration.

AI summary
A method for assisting a driver of a motor vehicle in clearing a path for emergency vehicles includes detecting a traffic jam situation for the motor vehicle, determining a need to clear a path for emergency vehicles on the basis of the detected traffic jam situation, detecting the driver's viewing direction, and semi-automatically or fully automatically controlling the motor vehicle according to the determined need to clear a path for emergency vehicles and the driver's detected viewing direction.
