Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective communication with emergency vehicles regarding their operational modes and right-of-way behaviors, which can lead to unclear interactions and potential safety issues during emergency situations.
Innovation Solution
An autonomous host vehicle equipped with a detection system that uses sensors and communication protocols to identify emergency vehicles and transmit operational data to them, including information on nearby vehicles' autonomous status and mode changes, allowing the emergency vehicle to determine which vehicles are autonomously operated and have ceded right-of-way.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles operate in normal mode without special emergency communication, then their operational complexity is reduced, but safety and coordination with emergency vehicles deteriorate
Solution Approach 1:
The patent introduces an emergency communication mode as an intermediary state that activates only during emergency situations. This mediator layer enables specialized communication between autonomous vehicles and emergency vehicles without requiring permanent complex communication infrastructure. The system uses standard vehicle sensors and communication protocols, activating emergency-specific functions only when needed, thus resolving the contradiction between reliability improvement and complexity increase.
Solution Approach 2:
The communication system dynamically switches between normal operational mode and emergency mode based on detected emergency vehicle presence. When an emergency vehicle is detected via sensors or communication signals, the autonomous vehicle transitions to emergency mode, activating enhanced communication protocols and operational adjustments. This dynamic adaptation allows the system to maintain low complexity during normal operation while providing high reliability when needed.
2Reliability
If autonomous vehicles continuously monitor and communicate with emergency vehicles, then safety and situational awareness improve, but energy consumption and computational load increase
Solution Approach 1:
The system employs periodic monitoring and communication rather than continuous operation. During normal conditions, autonomous vehicles perform standard periodic sensor scans and communications. Upon detecting an emergency vehicle through initial sensor detection or emergency signals, the system intensifies monitoring frequency and activates emergency communication protocols. This periodic activation strategy maintains situational awareness while minimizing unnecessary energy consumption during non-emergency periods.
Solution Approach 2:
The system prepares emergency response capabilities in advance by having detection systems and communication protocols pre-configured but dormant. When an emergency vehicle is detected, these pre-prepared systems activate immediately without requiring real-time setup or configuration. This preliminary preparation ensures rapid response and high situational awareness during emergencies while keeping energy consumption low during normal operation, as the systems remain in standby mode rather than continuously active.
3Reliability
If autonomous vehicles implement emergency mode with right-of-way ceding, then coordination with emergency vehicles improves, but operational flexibility and route adherence deteriorate
Solution Approach 1:
The patent segments the autonomous vehicle's operational modes into distinct states: normal mode and emergency mode. Each mode has clearly defined operational characteristics and right-of-way rules. In normal mode, vehicles follow standard routing and operational protocols. Upon detecting an emergency vehicle, the system transitions to emergency mode, where predefined protocols dictate right-of-way ceding behaviors. This segmentation allows the vehicle to maintain route flexibility during normal operation while ensuring reliable coordination during emergencies without permanent operational constraints.
Solution Approach 2:
The system dynamically adjusts operational behavior based on emergency vehicle presence. During normal operation, autonomous vehicles maintain full operational flexibility and route adherence to their planned destinations. When an emergency vehicle is detected and emergency mode is activated, the system dynamically modifies operational parameters to cede right-of-way, adjusting speed, lane position, and routing decisions as needed. Once the emergency vehicle passes or emergency mode is deactivated, the system returns to normal operational flexibility, allowing the vehicle to resume its original route and operational characteristics without permanent restrictions.
Data Source
AI summary
A vehicle computing device has a data storage medium and a processing device programmed to execute instructions stored on the data storage medium. The instructions include detecting an emergency vehicle near an autonomous host vehicle, receiving operational data from nearby vehicles, and transmitting the operational data to the emergency vehicle. The operational data indicates whether one or more of the nearby vehicles is operating in an autonomous mode.
