Parking Assistance System Positioning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems often result in vehicles being positioned unfavorably in parking spaces, leading to wasted space or potential damage due to inadequate distance from adjacent vehicles, especially in tight spaces like garages or narrow parking lots, and lack efficient automatic or semi-automatic control for optimal positioning.
Innovation Solution
A method for controlling a parking assistance system that evaluates sensor data for obstacle distances and vehicle speed/steering position to automatically or semi-automatically adjust the vehicle's position, allowing for optimal placement within a parking space, including minimizing distance from obstacles and folding in exterior mirrors for improved maneuverability, with the capability for fully automatic or semi-automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver manually drives into a parking space, then the driver has control over the parking position, but the vehicle may end up in an unfavorable position wasting space or being too close to adjacent vehicles
Solution Approach 1:
The system enables the vehicle to park itself automatically by evaluating sensor data about obstacles and parking area boundaries, and autonomously determining the optimal parking position and trajectory without requiring manual driver intervention for positioning control
Solution Approach 2:
The system continuously evaluates sensor data during the parking maneuver to monitor the vehicle's position relative to obstacles and boundaries, and uses this feedback to dynamically adjust the trajectory and steering commands to achieve optimal parking positioning
2Productivity
If the vehicle is positioned closer to obstacles to maximize space utilization, then space efficiency improves, but the risk of damage from adjacent vehicles increases
Solution Approach 1:
The system continuously monitors the vehicle's distance to obstacles and adjacent vehicles using sensor data during and after parking, and can automatically adjust the parking position to maintain a safe minimum distance while still maximizing space utilization
Solution Approach 2:
The system evaluates obstacle positions and potential collision risks before finalizing the parking trajectory, and pre-calculates the optimal parking position that balances space utilization with safety margins from adjacent vehicles
3Manufacturing precision
If automatic parking control is implemented to achieve optimal positioning, then parking position precision improves, but the system complexity increases
Solution Approach 1:
The system uses existing standard sensors in vehicles (ultrasonic sensors, cameras, speed sensors, steering angle sensors) that serve multiple functions including obstacle detection, distance measurement, and trajectory evaluation, thereby achieving automatic parking control without adding significant system complexity
Solution Approach 2:
The system combines data from multiple existing sensors (ultrasonic distance sensors, cameras, speed sensors, steering angle sensors) into a unified evaluation process that simultaneously determines obstacle positions, parking area boundaries, and optimal parking trajectory

AI summary
The method involves evaluating sensor data, which is related to distance to an obstacle in a parking space, and speed and/or steering position data of a vehicle (1). A parking assistance system is controlled using the evaluated sensor data. Automatic or semi-automatic correction, which is produced by a driver of the vehicle, to a laterally offset parking position is performed, during automatic or semi-automatic detection of the parking space. An optimal parking position of the parking space lies outside a central parking position in the parking space.
