Overhead Hazard Warning for Low-Clearance Vehicle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for preventing collisions between large vehicles and overhead obstacles are either too expensive, difficult to use, or ineffective, posing a significant risk of damage and injury due to unmarked or mismarked bridges and overpasses.
Innovation Solution
A system that includes a database storing overhead hazard locations and heights, using sensors and geolocation to update this information, and providing real-time warnings to drivers through a warning module if an obstacle is too low for safe passage, with algorithms for deduplication and time-based removal of resolved hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing overhead hazard detection systems are implemented, then collision prevention capability is improved, but system cost and complexity increase
Solution Approach 1:
The patent combines multiple hazard detection methods (sensor-based detection, database lookup, and driver reporting) into a single integrated system. The processing unit merges data from overhead hazard sensors, compares it with database information, and integrates driver reports to create a comprehensive hazard warning system, reducing overall system complexity while maintaining high reliability
Solution Approach 2:
The system performs multiple functions using a single integrated architecture: it detects overhead hazards via sensors, queries database for hazard information, processes driver reports, and provides warnings. This multi-functional approach eliminates the need for separate dedicated systems for each function, reducing cost and complexity while improving collision prevention capability
2Measurement precision
If comprehensive overhead hazard data is collected and stored, then hazard detection accuracy is improved, but data management complexity increases
Solution Approach 1:
The system automatically manages hazard data through self-service mechanisms: the processing unit autonomously queries the database using GPS coordinates, automatically processes and validates driver reports, and dynamically updates the overhead hazard database without manual intervention. This automation reduces data management complexity while maintaining high detection accuracy
Solution Approach 2:
The system implements feedback loops where driver reports are processed and used to update the database, which in turn improves future hazard detection accuracy. The processing unit continuously compares sensor data with database information and adjusts warnings based on feedback from both sources, creating a self-improving system that maintains high accuracy without increasing management complexity
3Reliability
If real-time hazard warnings are provided to drivers, then collision avoidance effectiveness is improved, but system response time requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-loading overhead hazard database information before the vehicle reaches hazard locations. The processing unit queries the database in advance using GPS coordinates and prepares warning information ahead of time, ensuring immediate warning capability when hazards are detected without requiring extended real-time processing
Solution Approach 2:
The system dynamically adjusts its response based on real-time conditions: it activates warnings immediately when hazards are detected ahead of the vehicle, adjusts warning timing based on vehicle speed and proximity to hazards, and dynamically updates the database as new hazards are reported. This dynamic approach maintains high collision avoidance effectiveness while optimizing response time

AI summary
A system to warn a driver of an overhead hazard, featuring a database that stores overhead hazard locations and heights, processing circuitry, and memory with instructions. It transmits overhead hazard data to a warning module associated with a first vehicle, receives new overhead hazard information from an overhead hazard tracker associated with a second vehicle, and updates the database. The system can include a warning module that alerts drivers if an overhead hazard is too low, with continuous updates for accuracy. It can remove resolved overhead hazards in the database using time-based algorithms and it can remove duplicate overhead hazards in the database with deduplication algorithms. Additionally, the invention includes a method of warning a driver of an overhead hazard and non-transitory computer-readable medium containing instructions that, when executed, perform the same method.
