Adaptive Parking Guidance Markers for Driver Burden Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking guidance systems are not intuitive, have low usability, and fail to adapt to surrounding situations, often requiring drivers to park along a guidance line, which can be oppressive and lacks adaptive control options.
Innovation Solution
A parking guidance apparatus and method that recognizes empty parking spaces, sets a target parking space, calculates one-step and multi-step parking routes based on driver input, and displays distinct guidance markers to guide parking, using image acquisition, distance sensing, and steering angle feedback to provide adaptive guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guidance line is displayed to perform parking guidance, then parking guidance function is provided, but driver burden increases and usability decreases due to oppressive sensation
Solution Approach 1:
The parking route is divided into multiple segments with distinct markers indicating different phases (approach, turning, parking). This segmentation provides clearer directional guidance without overwhelming the driver with a single continuous line, reducing the oppressive sensation while maintaining guidance effectiveness.
Solution Approach 2:
Instead of showing a continuous guidance line that constrains the driver, the system displays discrete markers that indicate key positions and turning points. This inversion from continuous to discrete guidance reduces the feeling of being forced to follow a rigid path while still providing comprehensive guidance.
2Adaptability or versatility
If parking guidance is controlled by a determined formula, then guidance can be provided, but adaptive guidance depending on surrounding situation becomes impossible
Solution Approach 1:
The parking guidance system dynamically adjusts the route and markers based on real-time steering input from the driver. The system calculates both one-step and multi-step routes adaptively, allowing the guidance to evolve with the driver's actions and surrounding conditions rather than following a predetermined fixed path.
Solution Approach 2:
The system continuously monitors steering input and vehicle position, using this feedback to recalculate and update the parking route in real-time. This feedback mechanism enables adaptive guidance that responds to driver behavior and changing surrounding situations, transitioning from formula-based to situation-aware control.
3Adaptability or versatility
If only one parking route is provided, then guidance is simple, but driver cannot select optimal route based on preference or situation
Solution Approach 1:
The guidance system provides multiple parking route options (one-step and multi-step routes) simultaneously, allowing drivers to choose based on their preferences and situational constraints. This multi-functionality enables the system to serve different driving styles and parking scenarios without requiring separate systems.
Solution Approach 2:
The system dynamically generates and presents multiple route options based on real-time conditions and driver input. Rather than providing a single static route, the guidance adapts to show alternative paths, enabling drivers to select the most suitable option while the system maintains the capability to provide multiple functions.

AI summary
There are provided a parking guidance apparatus and method. The parking guidance apparatus is configured to recognize parking spaces in which a vehicle is to be parked within a parking lot, to set any one of the recognized parking spaces to a target parking space, to calculate a one-step parking route and a multi-step parking route depending on a steering input of a driver, to display guidance markers corresponding to the one-step parking route and the multi-step parking route so as to be distinguished from each other, and to guidance parking on the basis of the guidance markers.
