Parking Trajectory Detection for Automated Exit Strategy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems require drivers to manually input the type and direction of parking maneuvers, leading to potential errors and reduced acceptance due to non-intuitive operation.
Innovation Solution
A method that automatically detects and records the vehicle's trajectory during parking, subdivides it into approach and parking trajectories, determines the type of parking space, and stores this data for later use, allowing the system to select an appropriate exit strategy independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input methods (buttons, rotating elements, touch screen) are used to enter parking space type and direction, then the system can obtain necessary information, but the operation becomes non-intuitive and error-prone
Solution Approach 1:
The system automatically detects and records the vehicle's trajectory during parking maneuvers using sensors, eliminating the need for manual driver input. The control device independently determines the parking space type and direction by analyzing the recorded trajectory data, making the system self-sufficient and removing the error-prone manual input step entirely
Solution Approach 2:
The patent replaces manual mechanical input methods (buttons, rotating elements, touch screen interactions) with an automated sensor-based detection system. Sensors record the vehicle's trajectory, and a control device processes this data to automatically determine parking parameters, substituting physical manual operations with electronic detection and processing
2Reliability
If the system restricts assistance to only previously parked spaces (where information is already stored), then information accuracy is maintained, but system versatility and driver acceptance are reduced
Solution Approach 1:
The system performs preliminary detection and recording of the vehicle's trajectory during the parking maneuver itself. By capturing and storing trajectory data at the time of parking, the system prepares the necessary information in advance, making it available for future exit maneuvers without requiring pre-stored information about specific parking spaces
Solution Approach 2:
The system is designed to handle various parking scenarios (different space types, directions, and maneuvers) through a single universal trajectory detection and analysis mechanism. The control device can process trajectory data from any parking situation and automatically determine the appropriate parking space type and direction, making the system adaptable to all parking scenarios rather than requiring pre-programmed information for each case

AI summary
The invention relates to a method for determining a strategy for leaving a parking space and to a device for performing the process. The method consists of the following steps: a) detection of a trajectory (3, 6) that describes the movement of the vehicle (1) before and during the parking in a parking space (8, 15, 16), b) division of the trajectory (3, 6) into an approach trajectory (2), a parking trajectory (5) and, if applicable, additional partial trajectories, wherein the approach trajectory (2) describes the vehicle movement during the approach and the parking trajectory (5) describes the vehicle movement during the parking, c) determination of the type of parking space, d) storage of the parking space type and/or the trajectory (3, 6), e) selection of a strategy for leaving the parking space depending on the type of parking space detected.
