Pull-in Parking System Automatic Steering Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking systems with both longitudinal and lateral guidance face challenges in minimizing dwell time at stopping points, leading to increased subjective and objective waiting times, especially during multi-point parking maneuvers, as they rely on driver actions and reactions.
Innovation Solution
A method that calculates a parking trajectory with multiple stopping points and detects their reach independently of driver actions, providing a signal for automatic steering control to initiate deflection, eliminating the need for driver-initiated gear changes and reducing reaction time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the system waits for driver-initiated gear change to detect stopping point, then the driver has control over the maneuver, but the dwell time at stopping point increases due to driver reaction time
Solution Approach 1:
The parking system detects the stopping point automatically using sensor data without requiring driver action or reaction. The system serves itself by monitoring its own state and environment, eliminating the need for driver intervention at stopping points.
Solution Approach 2:
The manual driver action of gear changing is replaced by an automated sensor-based detection system. The mechanical interaction between driver and vehicle controls is substituted with electronic sensing and automatic signal processing.
2Productivity
If the system uses driver actions to initiate deflection, then the driver remains engaged in the process, but the overall parking maneuver duration increases
Solution Approach 1:
The system performs preliminary detection of the stopping point using already-acquired sensor data before the driver can react. This advance detection enables the system to prepare and execute the deflection signal without waiting for driver action, thereby accelerating the overall process.
Solution Approach 2:
The system continuously monitors sensor data to detect when the stopping point is reached and provides immediate feedback by triggering the deflection signal. This closed-loop feedback mechanism ensures rapid response and minimizes delays in the parking maneuver.
3Loss of time
If the system requires driver recognition and action at stopping points, then the driver maintains awareness, but both objective and subjective waiting time increase
Solution Approach 1:
The system independently monitors its own position and detects stopping points using sensor data without requiring driver attention or recognition. The system takes care of itself by automatically determining when deflection should occur.
Solution Approach 2:
The sensor monitoring continues uninterrupted throughout the parking maneuver, ensuring that stopping points are detected immediately when reached. This continuous action eliminates gaps in detection that would otherwise require driver recognition and response.

AI summary
The invention relates to a method in a pull-in parking system for supporting pull-in parking, having a longitudinal guide and a transverse guide, and to such a pull-in parking system. A method according to the invention comprises the following steps: calculating a pull-in parking trajectory having at least one stopping point; detecting (306) that the calculated stopping point has been reached, independent of driver actions; and providing (308) a signal for changing direction for a steering controller as a reaction to the detection. Initiating 502 a change in direction thus takes place on a time axis 500 in the time period 504 before a point in time 506 at which the driver changes the gear, and independent thereof.
