Cooperative Driving Strategy Based on Vehicle Security Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles face challenges in safely performing cooperative driving, especially in environments where accidents are likely, due to the need to share information with neighboring vehicles and determine optimal driving conditions, which can impact safety.
Innovation Solution
A method that identifies the security status of cooperative driving target vehicles and adjusts the cooperative driving strategy accordingly, including changing the class of cooperative driving, abstaining from it, or performing alert driving based on the vehicle's security status, using a communication unit to communicate with target vehicles and a control unit to determine and execute the driving strategy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cooperative driving is performed by sharing information with neighboring vehicles, then driving efficiency and traffic flow optimization are improved, but safety risk increases due to potential security issues with target vehicles
Solution Approach 1:
The system performs preliminary security status identification of the target vehicle before executing cooperative driving. The control unit identifies the security status of the target vehicle through communication with its onboard unit, and only proceeds with cooperative driving when the security status is confirmed as normal, thereby preventing safety risks before they occur
Solution Approach 2:
The patent introduces a security status identification mechanism as an intermediary between information sharing and cooperative driving execution. This intermediary layer verifies the security status of target vehicles, allowing the system to filter out potentially harmful interactions while maintaining beneficial cooperative driving opportunities
2Reliability
If the system identifies and responds to security status changes in real-time, then safety is improved, but system complexity increases due to additional monitoring and decision-making layers
Solution Approach 1:
The cooperative driving system dynamically adjusts its operation based on the security status of target vehicles. The control unit continuously monitors security status changes and adapts the cooperative driving execution accordingly - proceeding when status is normal and aborting when security issues are detected, creating a flexible and adaptive safety mechanism
Solution Approach 2:
The system implements a feedback mechanism where the control unit receives security status information from the target vehicle's onboard unit, processes this information, and adjusts cooperative driving execution based on the received feedback. This closed-loop approach ensures continuous safety verification without requiring overly complex predetermined rules
3Reliability
If the system abstains from cooperative driving when security status is uncertain, then safety is improved, but driving productivity decreases due to lost cooperative opportunities
Solution Approach 1:
The system changes the operational parameters of cooperative driving based on the security status parameter of the target vehicle. When security status is normal, full cooperative driving is executed; when security status indicates potential risks, the system modifies parameters to abstain from or abort cooperative driving, thereby dynamically optimizing the balance between safety and productivity

AI summary
There is provided a cooperative driving control method based on a vehicle security status. The cooperative driving method according to an embodiment includes: identifying a security status of a cooperative driving target vehicle; determining a cooperative driving strategy according to the identified security status; and controlling driving according to the determined cooperative driving strategy. Accordingly, cooperative driving may be performed or excluded based on a security status of a target vehicle, so that an accident may be prevented from being caused by cooperative driving with a problematic vehicle, and safety of a driver and an occupant may be guaranteed.
