AVM Parking Guidance Inner-Side Line Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking guidance systems using around view monitors (AVM) face challenges in displaying guidance lines effectively due to limitations in the 360-degree view on the screen, making it difficult for drivers to intuitively determine the precision of alignment between guidance lines and parking section lines, especially during perpendicular and parallel parking.
Innovation Solution
A parking guidance method that uses an inner-side line instead of an outer-side line, displaying a parking reference region or line on the AVM screen, guiding the vehicle to align with the parking section line based on the inner trajectory of the vehicle's turning, and adjusting the steering wheel angles to facilitate precise parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an outer-side guidance line is displayed on the AVM screen, then the guidance line can be displayed, but the driver cannot intuitively determine the precision of alignment between the guidance line and parking section line
Solution Approach 1:
The patent switches from displaying an outer-side guidance line to displaying an inner-side guidance line. This inversion allows the guidance line to be properly displayed within the limited AVM screen view and enables the driver to intuitively determine alignment precision by comparing the inner-side line with the parking section line, resolving both the display limitation and the intuitive determination problem
2Area of stationary object
If the AVM screen displays 360 degrees around the vehicle, then surrounding information is covered, but the guidance line cannot be appropriately displayed due to view amount limitation
Solution Approach 1:
The patent inverts the guidance line position from outer-side to inner-side, allowing the guidance information to be displayed within the existing 360-degree AVM view without requiring additional screen real estate or complicating the display system architecture
3Reliability
If a guidance line is displayed parallel to the outer trajectory, then collision avoidance can be supported, but the driver cannot easily determine matching precision with parking section line
Solution Approach 1:
The patent inverts from using an outer trajectory-based guidance line to an inner trajectory-based guidance line. The inner-side line provides better visual correlation with the parking section line, enabling the driver to easily assess matching precision while still maintaining collision avoidance capability through the AVM system

AI summary
There is provided a parking guidance method for a vehicle, of displaying a guidance line for guidance of perpendicular, parallel parking in an AVM synthetic image to provide parking guidance. The method includes entering a parking support mode, displaying parking type information in the parking support mode to select a parking type, displaying a parking reference region or a parking reference line with regard to a parking target space in which the vehicle is to be parked depending on the parking type, displaying a parking alignment reference line when the vehicle travels at a relatively low speed and a steering angle thereof is changed by a threshold value or more, and guiding the vehicle to be aligned such that the parking alignment reference line coincides with a parking section line based on the parking reference region or the parking reference line.
