ITSI Control for Autonomous Vehicle Collision Escape Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in preventing escape and managing accidents, as they lack the ability to switch control rights to human drivers effectively, leading to potential secondary accidents and difficulties in handling situations where human intervention is necessary.
Innovation Solution
The implementation of an Intelligent Transportation System Infrastructure (ITSI) that communicates with autonomous vehicles to detect collisions, determine escape scenarios, and manage control rights, including the transmission of collision occurrence notifications and position information, to prevent further accidents and ensure safe vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous driving control is maintained after collision, then escape prevention is improved, but further accident risk increases
Solution Approach 1:
The patent implements dynamic control right management where the ITSI adjusts control authority based on real-time vehicle status and location. After collision detection, the system dynamically transitions from autonomous control to ITSI-managed control, allowing adaptive response to changing conditions while preventing both escape and secondary accidents
Solution Approach 2:
The system continuously monitors vehicle position, collision status, and control effectiveness through feedback loops. The ITSI receives real-time data from the autonomous vehicle and adjusts control commands based on this feedback, enabling dynamic optimization of safety outcomes post-collision
2Adaptability or versatility
If control rights are switched to human driver, then accident handling flexibility is improved, but escape risk increases
Solution Approach 1:
The ITSI serves as an intermediary control system between the autonomous vehicle's control system and potential human intervention. Rather than directly switching to human driver control, the ITSI mediates by implementing its own control protocols that prevent escape while still allowing necessary accident handling operations
Solution Approach 2:
The system performs preliminary control right management actions immediately upon collision detection, establishing ITSI control before any potential escape can occur. This preliminary action prevents the need for later control switches that could compromise safety
3Measurement precision
If ITSI monitors position continuously, then escape detection accuracy is improved, but communication load increases
Solution Approach 1:
The ITSI implements periodic position monitoring at optimized intervals rather than continuous monitoring. This periodic action maintains sufficient escape detection accuracy while significantly reducing the communication load and data transmission requirements between the vehicle and infrastructure

AI summary
A moving object escape prevention method includes: controlling, by a processor of a moving object, to drive the moving object based on autonomous driving; detecting, by the processor, whether a collision occurred by the moving object; in response to detecting the collision, transmitting, by the processor, a collision occurrence notification signal and position information of the moving object to an Intelligent Transportation System Infrastructure (ITSI); receiving, by the processor, escape-related information from the ITSI. The receiving escape-related information includes: determining, by the ITSI, whether or not the moving object escapes based on position information of the moving object; receiving, by the processor, accident handling information from the ITSI upon determining that the moving object does not escape, and receiving, by the processor, an escape warning message from the ITSI when the position information of the moving object changes.
