Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving control systems for autonomous vehicles struggle to ensure precision due to difficulties in handling safety envelope violations, making it challenging to maintain safety and compliance with driving policies.
Innovation Solution
A processing device and method that monitors safety envelope violations in autonomous vehicles, generates scenario information, and transmits it to a remote center for feedback, allowing the vehicle to adjust its driving based on the remote center's feedback to ensure compliance with safety policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving control is implemented based on local safety envelopes, then driving automation is achieved, but driving precision and safety compliance deteriorate due to inability to handle safety envelope violations
Solution Approach 1:
The system transmits safety envelope violation information to a remote center and receives feedback information in return. This feedback mechanism enables the autonomous vehicle to adjust its driving behavior based on remote analysis and guidance, thereby improving driving precision while maintaining automation. The feedback loop resolves the contradiction by providing external intelligence to enhance local autonomous decision-making.
Solution Approach 2:
The remote center acts as an intermediary between the autonomous vehicle and safety standards. When the vehicle encounters safety envelope violations, the remote center provides mediating feedback to guide the vehicle's response, ensuring compliance with driving policies without compromising automation capability.
2Manufacturing precision
If safety envelope violations are monitored and remote feedback is implemented, then driving precision is improved, but system complexity increases
Solution Approach 1:
The system extracts complex safety analysis functions to a remote center, keeping the local vehicle system relatively simple. The vehicle monitors for violations and transmits data, while the remote center handles sophisticated analysis and feedback generation. This extraction reduces local complexity while maintaining high driving precision through remote intelligence.

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 autonomous 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.
