V2V Safety System Path Guidance for Emergency Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle communication systems do not effectively provide drivers with real-time guidance on safer paths to navigate through various traffic scenarios, such as emergency vehicle routes or motorcycle passing situations, leading to potential safety hazards.
Innovation Solution
A vehicle safety system that utilizes V2V communication to receive and process broadcast signals from nearby vehicles, determining a recommended path based on vehicle data and identifiers, and displays this path to the driver through a graphical interface, allowing for lane changes or other maneuvers to enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2V communication is used to provide real-time path guidance, then driver safety and traffic flow are improved, but system complexity and information processing requirements increase
Solution Approach 1:
The system segments information processing by dividing V2V data into specific categories (emergency vehicles, motorcycles, lane information) and processing only relevant segments. The processor extracts only necessary path guidance information from broadcast signals, reducing overall processing complexity while maintaining safety improvements.
Solution Approach 2:
The system performs preliminary action by pre-defining response protocols for different vehicle types and scenarios. When an emergency vehicle or motorcycle is detected, the system has pre-programmed path adjustment rules ready, eliminating the need for complex real-time decision-making and reducing processing complexity.
2Measurement precision
If the system processes broadcast signals from multiple vehicles, then path determination accuracy is improved, but information processing time and computational load increase
Solution Approach 1:
The system applies local quality by focusing processing resources on locally relevant information only. It prioritizes broadcast signals from vehicles in immediate proximity and specific vehicle types (emergency vehicles, motorcycles) while filtering out distant or irrelevant signals, achieving accurate path determination without processing all available data.
Solution Approach 2:
The processor extracts only essential path guidance information from broadcast signals, separating critical data (vehicle type, position, lane information) from non-essential data. This extraction approach maintains path determination accuracy while significantly reducing processing time and computational load.
3Reliability
If the system provides detailed path guidance including lane changes, then driver safety is improved, but driver distraction and interface complexity increase
Solution Approach 1:
The system applies partial action by providing only the necessary portion of path guidance information - specifically lane change recommendations and critical maneuver alerts - rather than displaying complete route directions. This selective information provision improves safety without causing driver distraction from excessive displays.
Data Source
AI summary
A method of providing guidance in a host vehicle, including receiving a first broadcast signal transmitted by a first vehicle; and extracting vehicle data, a vehicle identifier, and a request from the first broadcast signal; responsive to the request, determining a recommended path for the host vehicle based upon the extracted vehicle data; and displaying or causing the displaying of the recommended path to the driver of the host vehicle.
