Parking Assist Controller Intention Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assist systems face difficulties in determining a driver's intention to park and selecting the appropriate parking mode, especially in tight spaces or when multiple vehicles are present, leading to increased search time and potential space occupation by other vehicles.
Innovation Solution
An apparatus and method that utilize a controller with a processor and memory to determine a driver's intention to park by analyzing vehicle and environmental information, setting a parking mode based on the vehicle's direction and gear position, and assisting in automatic parking using a head-on or reverse parking mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the driver manually selects a parking mode and the system searches for a parking space, then the parking control can be performed, but the searching time increases and other vehicles may occupy the target parking space
Solution Approach 1:
The system performs preliminary determination of driver's parking intention by analyzing vehicle state information (gear position, braking status, direction change rate) before initiating the parking search process. This preliminary action allows the system to prepare and execute parking maneuvers more quickly, reducing the time gap that allows other vehicles to occupy target spaces
2Productivity
If the system performs parking space search in tight spaces or areas with many vehicles, then a parking space can be found, but the searching time increases significantly
Solution Approach 1:
The system determines driver's parking intention in advance by monitoring vehicle state parameters (gear position, braking, direction changes) before the actual parking search begins. This preliminary determination allows the system to immediately initiate optimized search procedures when parking is intended, rather than waiting for manual input or performing exhaustive searches
Solution Approach 2:
The system uses multiple vehicle state parameters (gear position, braking status, direction change rate) to dynamically determine parking intention. By changing the parameters used for decision-making from simple manual selection to multi-parameter analysis, the system achieves faster and more accurate parking space acquisition
3Ease of operation
If the driver must select a parking mode in conventional systems, then the system can control parking, but the operation complexity increases and time is lost in selection
Solution Approach 1:
The system automatically determines the driver's parking intention by monitoring vehicle state information without requiring manual selection. The controller analyzes gear position, braking status, and direction change rate to autonomously decide when parking is intended, eliminating the need for drivers to manually select parking modes and significantly reducing operation time

AI summary
An apparatus and a method for parking assistance is provided that include a controller configured to determine an intention to park based on vehicle condition information and environmental information. In addition, the controller is configured to set a parking mode of a vehicle by analyzing the direction of the vehicle and a gear position, when the vehicle stops in an area in response to determining that the vehicle is to be parked. Furthermore, the controller is configured to assist the vehicle in automatic parking into a target parking lot based on the set parking mode.
