Parking Trajectory Adaptation for Accurate Repeated Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems for determining travel trajectories for parking maneuvers lack the ability to adapt and correct inaccuracies in recorded paths, leading to suboptimal positioning during repeated parking attempts, which can result in discomfort and inefficiency for users.
Innovation Solution
A device and method within a driver assistance system that records and adapts vehicle trajectories by using environmental data from sensors to adjust the path to align with target positions, allowing for precise and reliable automatic parking by storing and using adapted trajectories for repeated maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle uses a manually driven travel trajectory for automatic parking, then the parking maneuver can be repeated automatically, but the end position may deviate from the target position reducing accuracy
Solution Approach 1:
The system captures environmental data (images of parking space markings) during the parking maneuver, compares the actual end position with the target position, and uses this feedback to adapt and correct the travel trajectory for subsequent repetitions, ensuring accurate positioning while maintaining automation
Solution Approach 2:
The system adapts trajectory parameters (coordinates, orientation, speed) based on detected deviations from the target position, modifying the stored trajectory data to correct positioning errors while preserving the automated repetition capability
2Productivity
If the system records trajectory data for each parking maneuver, then the trajectory can be stored and reused, but deviations from target position accumulate and reduce reliability
Solution Approach 1:
The system continuously monitors positioning accuracy by comparing actual end positions with target positions using environmental sensor data, and automatically adjusts the trajectory parameters to compensate for deviations, maintaining reliability while enabling efficient repeated parking maneuvers
Solution Approach 2:
The system performs preliminary detection of parking space markings and target position before executing the parking maneuver, and pre-adapts the trajectory based on environmental data to prevent deviation accumulation from occurring in the first place

AI summary
An apparatus includes a device. The device is configured to determine a travel trajectory associated with repeated performance of a parking maneuver of a vehicle. The device is also configured to detect that a travel trajectory recorded associated with the parking maneuver includes an end position within a parking space which deviates from a target position. The device is also configured to determine a travel trajectory adapted with regard to the recorded travel trajectory associated with the parking maneuver so that the adapted travel trajectory includes an adapted target position which does not deviate from the target position. The device is also configured to use the adapted travel trajectory for repeated performance of the parking maneuver.
