Cooperative Driving Strategy Based on Neighbor 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 and responds to the security status of target vehicles by adjusting cooperative driving strategies, including changing cooperation classes or abstaining from cooperative driving, to ensure safety, using a communication unit to assess and control driving based on the security status of neighboring vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomous driving vehicles perform cooperative driving by sharing information with neighboring vehicles, then the ability to perform strategic tasks and optimize traffic flow is improved, but the risk of accidents and safety issues increases due to potential security vulnerabilities in 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 in advance, and only proceeds with cooperative driving when the security status meets predetermined safety criteria, preventing potential security-related accidents before they occur
Solution Approach 2:
The control unit acts as an intermediary that mediates between the desire for cooperative driving and safety concerns. It evaluates the security status of the target vehicle and makes the final determination on whether to permit cooperative driving, thus protecting the ego vehicle from potential security threats while still enabling cooperative driving when safe
2Productivity
If cooperative driving is performed in high-risk environments such as lane changes, overtaking, or intersection entry, then the efficiency and strategic task performance is improved, but the impact on driver and vehicle safety increases significantly
Solution Approach 1:
Before executing cooperative driving maneuvers in high-risk environments, the control unit performs preliminary identification of the target vehicle's security status. This preliminary check ensures that cooperative driving only occurs when the target vehicle presents no security threat, thereby maintaining driving efficiency while mitigating safety risks in critical situations
Solution Approach 2:
The system dynamically adjusts its cooperative driving behavior based on real-time security status assessment. When security status is favorable, cooperative driving proceeds to maintain efficiency; when security status deteriorates, the system aborts or avoids cooperative driving, thus dynamically balancing productivity and safety based on current conditions

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.
