Vehicle Safety Envelope Warning for Cooperative Driving Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving control technologies face challenges in effectively responding to other road users due to limited detection and communication capabilities, leading to potential safety envelope violations and accidents.
Innovation Solution
A processing method and system that monitor safety envelope violations between a host moving object and other road users, generating and transmitting warning information to ensure both objects are aware of potential risks, thereby improving response capabilities.
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 combines detection information from the host vehicle with communication information from target vehicles to comprehensively determine safety envelope violations. The determination unit integrates multiple information sources including detection information about other road users, communication information about detected objects, and position information to accurately identify when the host vehicle violates another vehicle's safety envelope
Solution Approach 2:
The communication unit serves multiple functions: it receives information from target vehicles about their detected objects, transmits the host vehicle's detection information to other vehicles, and enables cooperative awareness of safety violations among multiple road users
2Reliability
If the host vehicle monitors safety violations with respect to all other road users, then the safety coverage is comprehensive, but the processing complexity increases
Solution Approach 1:
The patent divides the safety monitoring task into segments: the host vehicle monitors its own safety envelope violations, while target vehicles independently monitor their own violations. Each vehicle's determination unit focuses on evaluating whether other road users (including the host vehicle) violate its safety envelope, rather than one vehicle trying to monitor all violations system-wide
Solution Approach 2:
The communication unit provides feedback by transmitting information about safety violations and detected objects between vehicles. This feedback loop enables each vehicle to adjust its driving control based on real-time information about violations and the presence of other road users detected by neighboring vehicles
3Reliability
If warning information is transmitted to target moving object, then the response capability of both vehicles is improved, but the communication requirements increase
Solution Approach 1:
The communication unit transmits warning information about safety envelope violations to target vehicles in advance, before actual collision occurs. This preliminary warning enables target vehicles to take preventive actions such as adjusting their trajectory or speed to avoid the violation, thereby preventing accidents before they happen

AI summary
In one aspect, a processing method is executed by a processor to perform processing related to driving of a host moving object that is configured to communicate with a target moving object. The processing method includes: monitoring an envelope violation that is a violation of a safety envelope in which safety of intended functionality is set in the host moving object with respect to another road user other than the target moving object; and generating, when the envelope violation is recognized in the host moving object, warning information for warning of the envelope violation that is to be transmitted to the target moving object.
