Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic parking systems rely on driver interpretation of visual data from around-view monitoring systems, which do not assist in determining optimal parking areas or provide direct control for parking, making it difficult for inexperienced drivers to park vehicles efficiently.
Innovation Solution
An automatic parking system utilizing a smart key recognition processor, sensor units, and a controller that acquires and processes images from multiple cameras to recognize parking areas, calculate optimal parking paths, and control vehicle steering, acceleration, and braking to facilitate safe and efficient parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera-based around view monitoring system is used to display images around the vehicle, then the driver can see the surrounding environment, but the driver still has to manually determine parking conditions and cannot receive automated parking assistance
Solution Approach 1:
The patent introduces an intermediary system between the camera and the driver. The camera captures images which are then processed by a control unit that automatically identifies parking areas and generates control signals. This intermediary processing layer transforms raw visual information into automated parking decisions, resolving the contradiction between providing visual information and enabling automated assistance
Solution Approach 2:
The patent replaces the manual mechanical process of visual assessment and manual steering with an automated optical-mechanical system. The camera-based detection system substitutes the driver's visual judgment, and the automated control signals substitute manual steering operations, enabling the vehicle to park itself based on detected parking areas
2Device complexity
If the driver manually determines parking position using camera images, then the system structure remains simple, but inexperienced drivers cannot park efficiently and safely
Solution Approach 1:
The control unit performs preliminary analysis of camera images to identify suitable parking areas before the driver attempts parking. By pre-processing the visual information and determining parking feasibility, the system prepares the necessary data in advance, enabling efficient and safe parking decisions without requiring complex real-time processing during the actual parking maneuver
3Extent of automation
If automatic parking control is implemented using sensor data, then parking can be performed automatically, but the system cannot recognize optimal parking areas without image processing
Solution Approach 1:
The patent merges camera-based image processing with sensor-based detection systems. The camera provides visual information for identifying parking areas, while sensors provide precise positional and environmental data. By combining these different measurement modalities, the system achieves both automatic control capability and precise parking area recognition
Solution Approach 2:
The system implements feedback by continuously monitoring camera images and sensor data during the parking process. The control unit compares detected features with expected parking area characteristics and adjusts control signals accordingly. This feedback mechanism enables the automated system to accurately recognize and adapt to the actual parking environment

AI summary
There is provided an automatic parking system according to an exemplary embodiment of the present disclosure. The automatic parking system includes: a smart key recognition processor recognizing a smart key positioned in a first area; a sensor unit acquiring images around a subject vehicle if the smart key is recognized, and converting the acquired image into external images and synthesizing the images; a parking space recognizing sensor periodically receiving the external images and sequentially comparing the consecutive external images using an image recognition technology to recognize parking areas; and a controller calculating a moving path between a current position of the subject vehicle and an optimal parking area among the parking areas and controlling the subject vehicle based on the moving path, in which the parking space recognizing sensor may detect the parking areas in consideration of a length and a width of the subject vehicle.
