AVM-Based Parking Assistance Using Touch Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance systems using ultrasonic sensors struggle to accurately recognize parking spaces without obstacles, leading to potential incorrect parking or impossibility of parking in desired regions.
Innovation Solution
A parking assistance apparatus utilizing an Around View Monitoring (AVM) system, where users can set a target parking region by touching an AVM image on a touchscreen, with the system generating guide images and controlling the vehicle's steering based on user input to guide the parking path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasonic sensors are used to recognize parking spaces, then the system can detect obstacles, but it cannot accurately recognize parking spaces when no obstacles are present
Solution Approach 1:
The patent introduces AVM (Around View Monitoring) images as an intermediary visual representation between the ultrasonic sensors and the parking space recognition system. The AVM images provide a comprehensive visual field that allows the system to identify parking spaces even when no obstacles are detected by ultrasonic sensors, thereby resolving the contradiction between detection capability and adaptability to different parking scenarios
2Reliability
If the system requires obstacles to be present for parking recognition, then ultrasonic sensor detection is reliable, but parking cannot be performed in desired regions without obstacles
Solution Approach 1:
The patent makes the parking assistance system universal by integrating multiple detection methods: ultrasonic sensor detection for obstacle identification and AVM image analysis for parking space identification. This multi-functional approach allows the system to operate reliably whether obstacles are present or absent, enabling users to park in any desired region while maintaining detection reliability
3Device complexity
If conventional ultrasonic sensor systems are used, then the system structure is simple, but parking guidance accuracy is insufficient
Solution Approach 1:
The patent merges two previously separate systems: the ultrasonic sensor-based obstacle detection system and the AVM-based visual monitoring system. By combining these systems, the patent achieves both the simplicity of the original ultrasonic system and the high precision of image-based recognition, allowing accurate parking region identification without significantly increasing overall system complexity
