Vehicle Guidance System for Emergency Path Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicle drivers face challenges in recognizing and responding to changing traffic patterns and the presence of emergency vehicles, especially in crowded roadways where visibility is limited.
Innovation Solution
A vehicle guidance system that uses transceivers and controllers to receive information from other vehicles and stationary systems, determining a recommended path based on the operation and position of surrounding vehicles, and communicates this path to the driver through visual and haptic feedback, including lane changes and speed adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driver relies on personal assessment of traffic patterns, then the driver maintains control and decision-making authority, but the driver may fail to recognize changing traffic patterns or emergency vehicles beyond their perceptual abilities
Solution Approach 1:
The patent introduces an intermediary system comprising sensors, processors, and communication devices that act as a mediator between the driver and the complex traffic environment. This intermediary automatically detects emergency vehicles, analyzes traffic patterns, and provides guidance recommendations, thereby enhancing detection reliability without requiring the driver to manually assess all traffic conditions.
Solution Approach 2:
The system implements feedback by continuously monitoring traffic conditions, comparing detected patterns against safety criteria, and providing real-time guidance recommendations to the driver. This closed-loop feedback mechanism enables the system to adapt to changing traffic patterns and alert the driver to potential hazards that may be beyond human perceptual capabilities.
2Reliability
If the system provides comprehensive real-time guidance on all traffic conditions, then safety is improved, but the system complexity and information processing requirements increase
Solution Approach 1:
The patent segments the complex traffic monitoring task into distinct functional modules: emergency vehicle detection sensors, traffic pattern analysis processors, guidance recommendation generators, and driver interface devices. This segmentation allows each component to specialize in specific functions, improving overall system reliability while managing complexity through modular architecture.
Solution Approach 2:
The system extracts and focuses specifically on detecting emergency vehicles and critical traffic patterns rather than attempting to process all possible traffic information. By extracting only the most safety-critical elements, the system maintains high safety standards without requiring excessive computational resources or system complexity.
3Loss of information
If the driver is provided with detailed information about all surrounding vehicles, then the driver's awareness is improved, but the driver may experience information overload
Solution Approach 1:
The patent applies local quality by providing different levels of information detail based on the criticality and relevance of each traffic element. Instead of uniformly presenting all vehicle information, the system selectively highlights emergency vehicles and critical traffic patterns with enhanced visual or auditory signals, while providing less prominent display for routine traffic conditions, thereby maintaining information completeness while improving usability.
Data Source
AI summary
A disclosed vehicle guidance system includes a transceiver receiving information indicative of operating conditions of other vehicles along a roadway and a controller within a primary vehicle. The controller utilizes the received information indicative of operating conditions to determine a recommended vehicle path along the roadway responsive to the operation of the other vehicles, the position of the primary vehicle and a scenario selected based on both the information of operation of other vehicles and the position of the primary vehicle received by the controller. A communication device communicates the recommended vehicle path to the operator of the primary vehicle.
