Smart Parking Assist Distance Feedback for Manual Start Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart Parking Assist Systems (SPAS) face challenges in accurately guiding drivers to the automatic parking control start position and providing clear information on movement distances during manual operation periods, leading to difficulties in performing precise automatic parking control.
Innovation Solution
The system includes a parking space determining unit that uses sensors to set a parking space and an automatic parking control unit that calculates and displays progress and remaining distances to the set path, allowing drivers to manually navigate to the start position and ensuring accurate automatic parking control by providing intuitive distance information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver manually operates the vehicle to reach the automatic parking control start position, then the driver can reach the start position, but the vehicle frequently goes beyond the start position and it is difficult to perform accurate automatic parking control
Solution Approach 1:
The system provides real-time feedback to the driver by displaying the remaining distance to the automatic parking control start position through a notification unit. This feedback mechanism enables the driver to accurately judge when to stop manual operation, preventing the vehicle from going beyond the start position and ensuring precise automatic parking control can be performed.
2Loss of information
If the Smart Parking Assist System controls the vehicle movement from the parking space setting position to the automatic parking control start position, then the movement can be automated, but the system does not support this movement period and the driver does not know the required movement distance
Solution Approach 1:
The notification unit provides continuous feedback information about the remaining distance to the automatic parking control start position. This information feedback compensates for the lack of automated control during the manual movement phase, allowing the driver to understand the required movement distance and reach the start position accurately.
3Measurement precision
If the system provides detailed distance information during manual operation, then the driver can accurately reach the start position, but the system complexity increases
Solution Approach 1:
The system uses an existing notification unit within the Smart Parking Assist System to display distance information, leveraging existing system components rather than adding complex new hardware. This approach provides the necessary position accuracy while minimizing increases in overall system complexity.

AI summary
The present embodiments relate to a smart parking assist system and a control method thereof, and display the ratios of the progress distance and the remaining distance of the vehicle based on the distance by which the vehicle must move in the path set for each period in which automatic parking control is performed by a smart parking assist system, thereby allowing the driver to easily recognize the automatic parking control state of the vehicle and the distance by which the vehicle must move. Accordingly, the present embodiments may provide the driver with information on the automatic parking control state for each period of the automatic parking control, and may enable the driver to drive the vehicle to an accurate control position without exceeding the same in the period in which the vehicle is moved straight by the manual operation of the driver during the automatic parking control period.
