Virtual Parking Lines for Unmarked Lot Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking technologies struggle in parking lots without lines, as they rely on detected parking lines and may obstruct passage spaces, and cannot efficiently utilize available parking areas outside lines.
Innovation Solution
A parking assistance apparatus that generates virtual parking lines based on environmental information, such as vehicle patterns and movement directions, to identify allowable parking areas and guide vehicles to suitable spaces, ensuring safe passage and efficient parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image-based automatic parking function detects parking spaces based on parking lines, then parking space detection is straightforward, but it cannot work in parking lots without parking lines
Solution Approach 1:
The system creates virtual parking lines as digital copies of physical parking lines. When physical lines are present, the system detects and reproduces them as virtual lines that guide the parking assistance function. This allows the system to work with both marked and unmarked parking lots by generating appropriate virtual guidance structures.
Solution Approach 2:
The system changes the detection parameters based on the presence or absence of physical parking lines. When lines are detected, the system uses line-based detection parameters; when lines are absent, it switches to vehicle-based detection parameters that identify parking spaces by analyzing the positions and orientations of surrounding vehicles.
2Ease of operation
If driver manually sets target parking space through drag and touch interface, then parking space selection is flexible, but processing of setting separate target parking space causes inconvenience to driver
Solution Approach 1:
The system performs automatic parking space selection and vehicle guidance without requiring manual driver intervention. The parking assistance apparatus autonomously detects available parking spaces, determines the target parking position, and guides the vehicle through the parking maneuver, eliminating the time-consuming manual drag-and-touch interface operation.
Solution Approach 2:
The system pre-processes the parking lot environment to identify and evaluate multiple candidate parking spaces before the driver needs to select one. By preparing the parking space options in advance and automatically guiding the vehicle to the selected space, the system reduces the operational burden and time required from the driver.
3Ease of operation
If automatic parking function parks vehicle in target parking space set by driver, then parking space selection is straightforward, but parking lot is inefficiently used
Solution Approach 1:
The system provides feedback to the driver about the selected parking space and offers alternative options that would improve parking lot utilization. The parking assistance apparatus analyzes the parking lot layout and vehicle dimensions to suggest optimal parking positions that maximize space usage, and can automatically adjust the target parking space selection to achieve better overall utilization.
4Measurement precision
If image-based automatic parking function senses parking space based on other vehicles, then parking detection is enhanced, but driving corridor area is not considered and sufficient passage space for other vehicles may be obstructed
Solution Approach 1:
The system performs preliminary analysis of the parking lot layout to identify and protect driving corridor areas before selecting parking spaces. By预先 determining which areas are designated for vehicle passage and maintaining clear zones in these corridors, the system prevents the host vehicle from obstructing other vehicles while still achieving accurate parking space detection based on surrounding vehicle positions.

AI summary
A parking assistance apparatus can include a sensor for sensing environment information of a vehicle surrounding area, a display for displaying an image of the vehicle surrounding area; and a processor to determine a parking area within the vehicle surrounding area on which parking is allowable, generate virtual parking lines within the parking area, and control the display to display the virtual parking lines, receive an input selecting a candidate parking space within the virtual parking lines, set the selected candidate parking space as a target parking position, and control a vehicle to be driven to the target parking position.
