Vehicle Safety Envelope Feedback for Manual Driving Violations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving control systems for host vehicles rely solely on internal and external environment detection, making it difficult to improve safety in manual driving scenarios due to the lack of external feedback on safety envelope violations.
Innovation Solution
A processing device and method that enables a host moving object to monitor safety envelope violations, generate scenario information, and transmit it to a remote center for feedback, allowing the host vehicle to enhance safety by incorporating external feedback based on the remote center's determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving control is planned based solely on internal and external environment detection, then the system structure remains simple, but safety improvement in manual driving scenarios cannot be achieved due to lack of external feedback
Solution Approach 1:
The patent implements a feedback mechanism where the host vehicle transmits safety envelope violation information to a remote center and receives determination results back. This external feedback loop enables safety improvement by incorporating remote expert judgment on whether violations constitute actual safety issues, resolving the contradiction between maintaining simple system structure and achieving safety improvement.
2Measurement precision
If the host vehicle transmits safety envelope violation information to the remote center, then safety determination accuracy improves, but communication requirements and system complexity increase
Solution Approach 1:
The remote center serves as an intermediary between the host vehicle's safety monitoring system and the final safety determination. Instead of requiring complex onboard AI to independently determine safety, the system uses the remote center as a mediator to provide expert judgment on safety envelope violations, improving determination accuracy while keeping the onboard system relatively simple.
3Loss of time
If real-time feedback is implemented between host vehicle and remote center, then safety response time improves, but communication bandwidth and processing load increase
Solution Approach 1:
The system extracts and transmits only the essential safety envelope violation information to the remote center, rather than transmitting all sensor data or continuous video feeds. This selective extraction of critical information reduces communication bandwidth requirements and processing load while still enabling timely safety determination and feedback.

AI summary
A processing device performing a process related to driving of a host moving object, which is capable of communicating with a remote center, is provided. The processing device includes a processor configured to: monitor a safety envelope violation, which is a violation of a safety envelope in which safety of intended functionality is set in compliance with a driving policy, in the host moving object in manual driving; in response to determining that the safety envelope violation is occurred, generate scenario information, which represents a scenario of the safety envelope violation, and transmit the scenario information to the remote center; and acquire feedback information from the remote center, the feedback information being fed back based on the scenario information.
