Parking Assistance System False Positive Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking assistance systems often incorrectly identify situations as parking spaces, leading to potential accidents, especially in cases of overtaking vehicles, oncoming vehicles, traffic islands, and perpendicular parking spaces, due to misinterpretation of vehicle gaps and boundaries.
Innovation Solution
The method involves suppressing the output of parking spaces for a specified distance when certain situations are detected, such as overtaking or oncoming vehicles, pedestrian crossings, or multi-lane roads, and aborting the parking process or issuing a warning to the driver, using a combination of sensors like ultrasonic, radar, and optical sensors to accurately determine the presence of a parking space based on vehicle movement and distance data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking space detection system actively searches for parking spaces using sensors, then the system can identify available parking spaces, but it may incorrectly identify non-parking spaces (such as gaps between overtaking vehicles, oncoming vehicles, or traffic islands) as parking spaces
Solution Approach 1:
The system continuously monitors the environment during the parking maneuver and provides feedback to the control unit. When sensors detect objects or situations that indicate a false parking space identification (such as overtaking vehicles, oncoming vehicles, or traffic islands), the system adjusts its behavior by suppressing parking space output, aborting the parking process, or warning the driver, thereby resolving the contradiction between active detection and false positive reductions
Solution Approach 2:
The system performs preliminary detection and evaluation of potential parking spaces before initiating the parking maneuver. By using sensors to scan the environment and the control unit to evaluate whether detected gaps are genuine parking spaces or false positives (such as gaps between moving vehicles), the system prevents incorrect parking attempts before they occur, thus improving reliability while reducing harmful false positives
2Object-generated harmful factors
If the system suppresses parking space output for a specified distance when certain situations are detected, then false positive detections are reduced, but the system may miss genuine parking spaces in those areas
Solution Approach 1:
The system dynamically adjusts its detection and output behavior based on real-time environmental conditions. When sensors detect specific situations (such as overtaking vehicles, oncoming vehicles, or traffic islands), the control unit temporarily suppresses parking space output for a specified distance. This dynamic adjustment allows the system to reduce false positives in dangerous situations while maintaining sensitivity to genuine parking spaces when conditions are safe, thereby resolving the contradiction between reducing false positives and detecting genuine parking spaces

AI summary
The invention relates to a method for assisting a driver of a motor vehicle (5) in which while the vehicle is moving the surroundings to the side next to the motor vehicle (5) are sensed in order to detect a parking space (3, 11). When a parking space (3, 11) is detected, a trajectory (23) is determined along which the motor vehicle (5) can park in the parking space (3, 11). During the parking process, the surroundings of the motor vehicle (5) are monitored. When a predefined situation is detected, the outputting of the parking space is prohibited for a predefined distance, the parking process is aborted or a warning is output to the driver. The invention also relates to a device for carrying out the method.
