Event Detection and Relay for Autonomous Vehicle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for technologies that can effectively record and analyze traffic accidents or incidents involving autonomous vehicles by utilizing devices with imaging functions positioned around the vehicle, as standalone autonomous vehicles may lack comprehensive coverage.
Innovation Solution
An information processing system comprising a detection unit, a determination unit, and a transmission unit that detects events, determines their level, and transmits information to a communication device, which relays this information through a network of devices with imaging capabilities, allowing for the capture and transmission of images and SOS packets without specifying a destination address, enabling comprehensive event analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous vehicles are used for driving operations, then driver workload is reduced, but the risk of traffic accidents and incidents increases
Solution Approach 1:
The patent introduces a server as an intermediary that collects and manages event information from multiple autonomous vehicles. The server acts as a central coordinator that processes detection results from various vehicles and communicates with other vehicles, thereby distributing the safety monitoring responsibility and reducing the burden on individual vehicle systems while maintaining or enhancing overall safety.
Solution Approach 2:
The server performs multiple functions including collecting event information from multiple vehicles, determining communication destinations based on event levels, relaying information between vehicles, and managing communication resources. This multi-functional approach allows a single system to handle various aspects of safety monitoring and coordination, improving reliability without proportionally increasing complexity.
2Device complexity
If autonomous vehicles operate independently, then vehicle control is simplified, but comprehensive event detection coverage is insufficient
Solution Approach 1:
The patent merges the detection capabilities of multiple autonomous vehicles by having them share event information through a server. Instead of each vehicle operating in isolation, their detection results are combined and analyzed collectively, creating a comprehensive view of traffic events that no single vehicle could detect alone, thereby compensating for individual sensor limitations.
Solution Approach 2:
The system implements feedback loops where detection results from one vehicle are communicated to others, and information about events detected by multiple vehicles is relayed back to relevant parties. This feedback mechanism ensures that detection gaps in one vehicle can be compensated by detections from others, improving overall event detection coverage.
3Reliability
If event information is transmitted to all vehicles, then comprehensive safety monitoring is achieved, but communication bandwidth is wasted
Solution Approach 1:
The patent applies local quality by determining communication destinations based on the specific event level and type. Not all vehicles receive all event information - instead, information is selectively transmitted to vehicles where it is most relevant and needed. This targeted approach maintains safety monitoring effectiveness while minimizing unnecessary communication bandwidth consumption.
Solution Approach 2:
The system changes the parameter of information transmission by varying the communication destination and content based on event level parameters. Different event levels trigger different transmission strategies, allowing the system to adapt communication patterns to the severity and nature of detected events, thereby optimizing bandwidth usage while maintaining appropriate safety monitoring.
4Reliability
If multiple devices relay information, then system robustness improves, but information transmission complexity increases
Solution Approach 1:
The server acts as a central intermediary that manages information relay between vehicles. Instead of vehicles directly communicating with each other in a complex mesh network, the server mediates all information exchange, simplifying the transmission logic while maintaining robustness through multiple relay paths. The server handles destination determination and information routing, reducing the complexity burden on individual vehicle systems.
