Cloud Vehicle Yielding Guide for Emergency Path Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult for drivers to rapidly yield to emergency vehicles, especially those with emergency patients, due to uncertainty about the location of emergency vehicles and the lack of recognition of non-emergency vehicles as such, leading to potential accidents and worsened conditions for patients.
Innovation Solution
A system and method utilizing a cloud-connected communication network between vehicles to transmit and receive signals, determining emergency states, and providing guide signals to surrounding vehicles to yield, including location, lane change direction, acceleration/deceleration instructions, and safety information to secure the path of emergency vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If yielding driving is performed based on siren recognition only, then emergency vehicles can pass, but non-emergency vehicles with emergency patients cannot be recognized and yield
Solution Approach 1:
The patent introduces a cloud server as an intermediary between vehicles and emergency centers. The cloud server receives emergency state information from the emergency center and transmits it to surrounding vehicles, enabling reliable recognition of emergency vehicles and situations beyond just siren detection.
Solution Approach 2:
The system extends emergency vehicle recognition beyond traditional emergency vehicles to include any vehicle in an emergency state, such as common vehicles carrying emergency patients. The cloud server handles multiple types of emergency situations uniformly through the same communication framework.
2Ease of operation
If drivers manually detect and yield to emergency vehicles, then yielding can be performed, but rapid response is difficult due to uncertainty about emergency vehicle location
Solution Approach 1:
The system performs preliminary action by proactively transmitting emergency state information to surrounding vehicles before the emergency vehicle arrives. The cloud server sends location and movement information in advance, allowing drivers to prepare for yielding immediately rather than reacting after hearing a siren.
Solution Approach 2:
The system implements feedback by continuously providing surrounding vehicles with real-time information about the emergency vehicle's location, movement direction, and speed. This feedback loop enables drivers to make informed decisions about yielding actions.
3Measurement precision
If comprehensive guide signals are transmitted to surrounding vehicles, then yielding accuracy is improved, but communication data volume and processing complexity increase
Solution Approach 1:
The patent segments the yielding guidance information into distinct components: location information, movement direction, speed information, and safety distance. This segmentation allows the cloud server to transmit comprehensive information while enabling receiving vehicles to process each parameter independently and efficiently.
Data Source
AI summary
A system and method for inducing vehicles to yield right of way determines whether a common vehicle is an emergency vehicle through a cloud, which transmits and receives requests and response signals between vehicles, when the common vehicle transmits a request signal showing that the common vehicle is an emergency vehicle, and informs surrounding vehicles that there is an emergency vehicle in a driving path and simultaneously provides a yielding driving guide signal, which includes a driving direction for yielding driving, a lane change direction of the emergency vehicle, whether to accelerate and decelerate, etc., to the surrounding vehicles so that yielding driving may be easily performed for specific vehicles with an emergency patient other than emergency vehicles such as an ambulance and a fire truck.
