Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a discrepancy in situation recognition between host and target vehicles, affecting the response to the behavior of moving bodies, which can lead to potential accidents.
Innovation Solution
A processing method and system that acquires warning information about envelope violations from a target moving object and adjusts or generates warnings based on a safety envelope to improve response capabilities, utilizing sensors, communication systems, and safety models to ensure compliance with driving policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving control is performed based on detection information from the host vehicle only, then the control system is simple, but the response capability to other road users is insufficient
Solution Approach 1:
The patent uses communication information from the target moving object as an intermediary to infer the presence and state of other road users. The target moving object's detection results and safety envelope data serve as mediating information that allows the host vehicle to indirectly monitor other road users without direct detection equipment, resolving the contradiction between response capability and system complexity.
Solution Approach 2:
The system implements feedback by continuously monitoring envelope violations and using the target moving object's communication data to update the host vehicle's understanding of the environment. This feedback loop enables the host vehicle to adjust its driving control based on inferred information about other road users, improving reliability while maintaining relatively simple system architecture.
2Reliability
If the host vehicle monitors envelope violations with respect to all road users directly, then the safety monitoring is comprehensive, but the system complexity and detection difficulty increase significantly
Solution Approach 1:
The target moving object serves as an intermediary that provides detection information about other road users. Instead of the host vehicle directly detecting all road users, it relies on the target moving object's detection results and safety envelope data as intermediary information, significantly reducing detection difficulty while maintaining comprehensive safety monitoring.
Solution Approach 2:
The safety monitoring task is segmented between the host vehicle and the target moving object. The target moving object handles direct detection and safety envelope monitoring for certain road users, while the host vehicle focuses on processing this information and monitoring violations related to its own safety. This segmentation reduces the detection burden on each individual vehicle.
3Reliability
If warning information is transmitted to the target moving object about envelope violations, then the response capability is improved, but the communication overhead increases
Solution Approach 1:
Warning information transmission is applied locally and selectively rather than universally. The host vehicle transmits warnings to the target moving object only when specific envelope violations are detected that affect the target moving object's safety. This localized approach improves accident prevention capability while minimizing unnecessary communication energy consumption.

AI summary
A processing method is executed by a processor for performing a process related to a driving control of a host moving object that is configured to communicate with a target moving object. The processing method includes: acquiring warning information from the target moving object, the warning information warning of an envelope violation that is a violation of a safety envelope in which a safety of an intended functionality is set, the safety envelope being set for the target moving object with respect to the host moving object; and adjusting the safety envelope with respect to the target moving object in response to acquiring the warning information.
