Automatic Parking Progress Feedback for User Input Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic parking systems lack user intuition regarding the time required for parking and unparking, and the progress of vehicle control, leading to degraded usability and convenience due to variable parking environments and potential incorrect or malicious user inputs.
Innovation Solution
The system includes a collecting device for environment and user input data, an automatic parking controller that calculates progress stages (wake-up request, control acquisition, execution request, control information generation, and vehicle control) and outputs this information through various devices like displays, audio, and haptic modules, allowing users to intuitively understand the parking process and preventing incorrect inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automatic parking system requires a preset time for user input to prevent incorrect or malicious inputs, then system security is improved, but the user cannot intuitively know the time required for parking, degrading usability
Solution Approach 1:
The system provides real-time feedback to the user through a display device, showing the current progress stage (first through fifth stages) and estimated time required for each stage. This feedback mechanism allows users to understand what the system is doing and how long it will take, maintaining security requirements while significantly improving usability and user confidence.
Solution Approach 2:
The automatic parking process is divided into five distinct stages: wake-up request determination, control right acquisition, execution request determination, control information generation, and vehicle behavior control. By segmenting the overall process into manageable stages with specific time estimates for each, the system makes the complex parking operation transparent and predictable for users.
2Device complexity
If the automatic parking system operates without providing progress information, then device complexity is reduced, but user convenience deteriorates as users cannot identify the progress of vehicle control
Solution Approach 1:
A display device serves as an intermediary between the automatic parking controller and the user. This intermediary translates complex controller operations into simple, understandable progress indicators showing which of the five stages is currently active, providing user convenience without adding complexity to the core parking control system.
3Ease of operation
If the system provides detailed progress information for each parking stage, then user convenience is improved, but information processing requirements increase
Solution Approach 1:
The progress information is segmented into five discrete, clearly-defined stages rather than providing continuous or overly detailed information. Each stage represents a specific milestone in the parking process, providing users with sufficient information to understand system status without generating excessive data processing requirements.

AI summary
An embodiment vehicle includes a collecting device for collecting environment information, a user input for automatic parking of the vehicle, an automatic parking controller for performing the automatic parking based on the environment information and the user input, and a behavior controller for controlling a behavior of the vehicle in response to control of the automatic parking controller. The automatic parking controller calculates a first progress corresponding to determination of whether the user input is a wake-up request, a second progress corresponding to acquisition of a control right for the behavior controller, a third progress corresponding to whether the user input is an execution request for the automatic parking, a fourth progress corresponding to generation of control information for the behavior controller, and a fifth progress corresponding to control of the vehicle's behavior.
