Evasive Steering Support Free Space Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems face challenges in reliably detecting free space for evasive maneuvers, particularly at high speeds and low friction conditions, where false negative errors can lead to unsafe situations, and existing systems are not adequately designed to prevent unreasonable dangers from misinterpreting the environment.
Innovation Solution
A method and device for reliable free space detection using environment detection systems, which verify potential free spaces by combining data from sensors, electronic maps, and additional vehicle information to ensure accurate identification of traversable areas, reducing the likelihood of false negatives and activating interventions only when conditions are positively recognized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system restricts evasive maneuver activation to verified traffic situations, then false activations are reduced, but the system complexity increases
Solution Approach 1:
The patent segments the verification process into distinct functional modules: object detection, free space determination, roadway verification, and traversability assessment. This modular segmentation manages system complexity by organizing verification tasks into separate, manageable components rather than a monolithic complex system
Solution Approach 2:
The verification system uses multi-functional sensors and processing units that serve both primary detection functions and verification functions. The environment detection system not only detects objects but also verifies free space conditions, making the system more efficient without proportionally increasing complexity
2Reliability
If additional verification checks are performed before evasive maneuver activation, then functional safety is improved, but the response time increases
Solution Approach 1:
The system performs verification checks in parallel with the detection process rather than sequentially after detection. By preliminarily assessing free space conditions alongside object detection, the system maintains functional safety while minimizing additional response time
Solution Approach 2:
The verification process skips unnecessary checks when conditions are clearly met. If the environment detection system confidently identifies a valid free space with clear traversability indicators, the system rushes through the verification process to minimize response time while still ensuring functional safety

AI summary
The invention relates to a method for a driver assistance system for a vehicle. Objects in the vehicle surroundings are detected using data of a surroundings detection system, and a potential clear area is ascertained, wherein no objects and/or just objects over which the vehicle can pass have been reliably detected in said clear area. The potential clear area is verified by means of additional vehicle and/or surroundings information.
