Parking Guidance Device Using Obstacle Detection for Space Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking lot guidance systems fail to accurately inform drivers of the size of available parking sections, leading to potential misjudgments and inability to park in vacant spaces due to adjacent vehicles or obstacles.
Innovation Solution
A parking lot guidance device that calculates and transmits the size of a parking section based on the distance to adjacent obstacles, allowing for inter-vehicle communication to relay exit information to prioritize vehicles, ensuring drivers can grasp the actual size of available spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver is notified of the area of a vacant parking section with a display pattern according to an evaluation value, then the driver can identify convenient parking sections, but the driver cannot grasp the actual size of each parking section in advance
Solution Approach 1:
The system performs preliminary measurement of parking section sizes using obstacle detection devices before the vehicle arrives. The controller calculates the size of each parking section in advance by detecting obstacles (vehicles, walls, etc.) and stores this information. When the vehicle approaches, the notification device displays both the evaluation value and the actual measured size, allowing the driver to make an informed decision before arrival.
Solution Approach 2:
The patent replaces manual estimation or visual judgment of parking section size with an automated obstacle detection system. The controller uses detection data from sensors (ultrasonic, infrared, or camera-based) to automatically calculate and determine the actual size of parking sections, substituting mechanical/visual measurement with electronic sensing and computational analysis.
2Ease of operation
If the notification system provides evaluation values for vacant parking sections, then parking convenience is improved, but parking failure occurs when the actual space is insufficient
Solution Approach 1:
The system provides feedback to the driver by displaying both the evaluation value (indicating convenience) and the actual measured size of the parking section. This dual-information feedback allows the driver to assess whether the parking section is both convenient and sufficiently large for their vehicle, enabling informed decision-making and reducing parking failures.
3Device complexity
If the parking lot guidance device uses simple display patterns, then the system complexity is reduced, but the driver cannot intuitively determine parking feasibility
Solution Approach 1:
The notification device displays different types of information (evaluation value and actual size) in distinct visual formats or locations. The evaluation value may be shown with color coding or icons indicating convenience, while the actual size is displayed separately with numerical or visual representation of dimensions. This differentiated local presentation allows drivers to quickly grasp both aspects without confusion.

AI summary
A parking lot guidance device includes a processor. The processor is configured to cause a communication unit to transmit exit information to a vehicle with the highest priority among other vehicles that are transmission targets. The exit information includes information of a size of a parking section in which a host vehicle is parked, information of a position of the parking section in which the host vehicle is parked, and information of a start of exit of the host vehicle.
