Parking Assist System for Optimal Space Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic parking assist systems fail to adequately inform drivers of parking space situations, leading to missed optimal parking spaces and decreased utility, especially when multiple spaces are found, and drivers may feel unfamiliar with the automatic parking process due to lack of information.
Innovation Solution
A parking assist apparatus and method that includes a parking space search unit, storage unit, output unit, and selection unit to identify, display, and allow drivers to select optimal parking spaces by generating and outputting parking space information, including width, length, direction, and object information, using sensors like cameras and ultrasonic sensors, and allowing in-vehicle communication for real-time data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional automatic parking assist system only sets the lastly found parking space as target, then the system operation is simple, but the optimal parking space may be missed and utility decreases
Solution Approach 1:
The system performs preliminary actions by searching for and storing multiple parking spaces before making a selection. The controller stores plurality of parking space information including position coordinates and dimensions, then presents these options to the driver before final selection, ensuring optimal spaces are not missed due to premature single-space selection
Solution Approach 2:
The system provides feedback to the driver by displaying detected parking space information through the output unit. The driver receives information about multiple available parking spaces and can provide feedback by selecting the desired space, creating a closed-loop system that prevents loss of optimal parking space information
2Productivity
If the system searches for another parking space during braking time, then continuous parking space detection is maintained, but the desired parking space may be replaced by a laterally found space
Solution Approach 1:
The system performs preliminary detection and storage of parking space information during the braking period before final selection. By storing multiple parking space candidates with their position and dimension data, the system preserves the driver's desired space information even while continuing to search for additional spaces
Solution Approach 2:
The system provides continuous feedback to the driver about detected parking spaces during braking. The output unit displays parking space information in real-time, allowing the driver to maintain awareness of the desired space while the system continues its search, preventing unintended replacement of the target space
3Device complexity
If parking space information is not provided to the driver, then the system structure is simple, but the driver feels unfamiliarity with the automatic parking process
Solution Approach 1:
The system provides feedback to the driver by displaying parking space information through the output unit. The detected parking spaces, their positions, and dimensions are presented to the driver, creating awareness and familiarity with the automatic parking process while maintaining relatively simple system architecture
Solution Approach 2:
The output unit serves as an intermediary between the detection system and the driver. It translates raw sensor data into comprehensible parking space information that the driver can understand and use for decision-making, enhancing familiarity without requiring complex direct interaction between sensors and driver
