Angle Parking Position Setter Using Marking Line Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems fail to ensure that vehicles are parked completely within the designated angle parking spaces, leading to potential obstacles for pedestrians and other vehicles.
Innovation Solution
A parking assistance device that determines the type of angle parking (back-in or nose-in) based on the angle between the vehicle and the marking lines, sets a parking position inside the space farther away from the vehicle, and automatically drives the vehicle into the determined position, avoiding obstacles by adjusting the drivable area based on the distance to other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle is parked by self-driving in the parking area detected from the camera image, then the parking maneuver is automated, but the front edge or rear edge of the vehicle may stick out from the parking area
Solution Approach 1:
The system performs preliminary detection of marking lines and calculation of the parking area before executing the self-driving parking maneuver. By pre-determining the parking position based on the detected marking lines and vehicle dimensions, the system ensures accurate positioning while maintaining automation throughout the parking process
Solution Approach 2:
The patent replaces manual parking operation with an automated control system that uses camera-based marking line detection, geometric calculation of parking area boundaries, and automated vehicle control. This substitution of mechanical/manual operations with automated systems achieves both high automation and precise parking positioning
2Productivity
If the vehicle is parked with the front edge or rear edge sticking out from the parking area, then the parking maneuver is completed, but the vehicle may become an obstacle to people walking in the lane or to another vehicle driving in the lane
Solution Approach 1:
The system continuously monitors the vehicle's position relative to the parking area boundaries during the parking maneuver and makes real-time adjustments. By providing feedback on the vehicle's actual position compared to the calculated parking area, the system ensures the vehicle is fully within the designated space, preventing it from becoming an obstacle while maintaining efficient parking completion

AI summary
A parking assistance device includes: a marking line detector that detects a plurality of marking lines delineating a parking area from an image taken by an imaging unit; a second determiner that determines whether or not the type of parking for parking a vehicle in a parkable area is angle parking, on the basis of the angle obtained between a parking baseline joining the endpoints on the vehicle side of the detected plurality of marking lines and the plurality of marking lines, or the angle obtained between the parking baseline and one marking line selected from among the plurality of marking lines; and a parking position setter that, in the case where the second determiner determines that the type of parking corresponds to angle parking, sets a parking position inside the parkable area in which to park the vehicle, on the basis of the parking baseline.
