Vehicle Parking Positioning Using Adjacent Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking support systems fail to achieve an optimal parking position in wide parking spaces and struggle when a space is only delimited on one side by an obstacle, making it difficult to determine whether a vehicle should be parked centrally or off-center to accommodate another vehicle.
Innovation Solution
The method involves determining the parking position of adjacent vehicles in wide parking spaces using measuring devices and evaluation units, which account for the width and lateral distances of parked vehicles to guide the positioning of the vehicle to be parked, ensuring it aligns with the adjacent vehicles' positions, thereby facilitating an optimal parking arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the parking position is determined based only on the width of the parking space and central alignment, then the parking process is simple to control, but an optimal parking position is not achieved in very wide parking spaces
Solution Approach 1:
The system performs preliminary scanning of adjacent parking spaces to detect parked vehicles before determining the parking position. This advance detection allows the evaluation device to use the positions of adjacent parked vehicles as reference information, enabling optimal positioning in wide parking spaces while maintaining simple control through automated evaluation.
2Shape
If the vehicle is parked in the middle of a wide parking space, then the parking position is centrally aligned, but space is wasted that could accommodate a second vehicle
Solution Approach 1:
The system uses feedback from the measuring device that detects the positions of vehicles parked in adjacent parking spaces. This feedback information is processed by the evaluation device to determine the optimal transverse position, allowing the system to adjust the parking position to maximize space utilization while maintaining appropriate clearance from boundaries.
3Device complexity
If the parking position is determined without considering adjacent parked vehicles, then the determination process is simple, but the system cannot assist when a parking space is only delimited on one side by an obstacle
Solution Approach 1:
The measuring device serves multiple functions: it measures the width of the current parking space and simultaneously detects the positions of vehicles in adjacent parking spaces. This multi-functionality allows the system to handle various boundary conditions (two-sided delimitation, one-sided delimitation, open spaces) without increasing device complexity, as the same device provides all necessary measurement data.

Function Achieved in This Case
This approach allows for reliable and efficient parking in wide spaces by determining the mean lateral position of adjacent vehicles, enabling vehicles to be parked in a manner that leaves space for others, improving the overall parking process and ensuring easy access for occupants.
Implementation Method 1
WO 2009/078356 A1 discloses a system that emits electromagnetic waves at predetermined time intervals to scan a predetermined angular range around the own vehicle in the horizontal direction. When the reflected waves of the electromagnetic waves reflected from an object are received, the points on the object where the electromagnetic waves are reflected are detected based on the reception results of the reflected waves.

AI summary
The method involves determining a parking position (G) of a parked vehicle (11-15) in a neighboring parking lot (P) by a measuring unit (9). The determined parking position is considered by an evaluation unit by determining the parking position of a vehicle (1). An independent claim is also included for a device for supporting a parking procedure of a vehicle in a parking lot arranged transverse to a lane.
