Intersection Vehicle Control Using Full-Length Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to accurately monitor and manage the movement of multiple vehicles and obstacles at intersections, leading to potential collisions due to incomplete information about the size and position of trailing vehicles or stationary obstacles, resulting in unsafe navigation through congested areas.
Innovation Solution
A vehicle control system that monitors the size and location of vehicles and obstacles, determines their position relative to intersections, and adjusts operating settings to prevent collisions by communicating commands or alerts to ensure safe movement and timing at intersections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vehicle system only receives information about the lead vehicle's location, then the information processing is simple, but the vehicle system cannot detect trailing vehicles or portions of vehicle systems that remain in the intersection, leading to collision risks
Solution Approach 1:
The system segments the detection task by monitoring individual vehicles within a vehicle system separately. Each vehicle's location is tracked independently using its own identifier, allowing the system to detect when trailing vehicles or portions of vehicles are in the intersection while maintaining manageable complexity through modular detection logic.
Solution Approach 2:
The system adds a dimensional approach by tracking not just the presence of a vehicle system but the specific location of each vehicle within it. This multi-dimensional tracking (vehicle system level + individual vehicle level) enables precise detection of trailing vehicles while the intersection allowance area provides a spatial dimension for collision risk assessment.
2Measurement precision
If the vehicle system does not account for obstacle size, then the navigation is simpler, but the vehicle system cannot gauge accurate distance to obstacles, leading to potential collisions
Solution Approach 1:
The system performs preliminary detection of obstacles and their sizes before the vehicle system approaches the intersection. By obtaining obstacle size information in advance and comparing it with the intersection allowance area, the system can calculate safe approach distances and adjust navigation accordingly, preventing collisions before they occur.
Solution Approach 2:
The system uses an intermediary approach by introducing a third-party monitoring system that provides obstacle information to the vehicle control system. This intermediary layer processes obstacle data, calculates risk assessments, and communicates with the vehicle system, simplifying the overall complexity while improving measurement precision.
3Reliability
If the vehicle system continues moving according to original operating conditions, then the productivity is maintained, but the vehicle system may collide with trailing vehicles or obstacles in the intersection
Solution Approach 1:
The system implements continuous feedback monitoring of the intersection area for trailing vehicles and obstacles. When potential collision risks are detected, the system provides feedback to adjust operating conditions, temporarily pausing or modifying movement to avoid collisions while maintaining overall productivity through efficient resumption of normal operations.
Solution Approach 2:
The system dynamically adjusts operating conditions based on real-time detection of trailing vehicles and obstacles. Rather than maintaining fixed operating conditions, the system can temporarily modify speed, pause movement, or change trajectory when intersection risks are detected, then resume normal operations when safe, balancing reliability with productivity.

AI summary
A vehicle control system and method includes obtaining a size of a vehicle system, identifying locations of different portions of the vehicle system, and determining one or more of a) whether the vehicle system is disposed within or across an intersection of routes or b) a predicted time of arrival at which the vehicle system will be disposed within or across the intersection based on the size of the vehicle system and the locations of the different portions of the vehicle system.
