Vehicle Parking Display Control System with Segmented Guidance Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for vehicle parking assist technologies often overlap guide lines with parking lines, making it difficult for drivers to intuitively determine the positional relationship between the vehicle and the parking space, thereby complicating the parking process.
Innovation Solution
A display control system that acquires video data from a rear camera, recognizes parking lines, generates a center line and center limit lines based on the vehicle's width, and superimposes a vehicle moving line on the video data to provide a clear visual representation of the parking space and vehicle path, reducing overlap and enhancing intuitive vehicle handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide line is superimposed on a rearward video image to indicate the predicted path of backward motion, then the vehicle can be guided to a parking space, but the guide line may overlap with the parking line making it difficult for the driver to visually determine the parking line
Solution Approach 1:
The patent divides the guidance information into multiple segmented lines: center line (indicating parking space center), center limit lines (indicating boundaries), and vehicle moving line (indicating predicted path). This segmentation allows each line to serve a specific function and reduces confusion compared to using a single guide line that might overlap with parking lines.
Solution Approach 2:
The patent introduces center limit lines as intermediary elements that represent the boundaries of the parking space. These lines act as mediators between the parking space geometry and the vehicle position, providing clear reference points that help drivers understand the spatial relationship without directly overlapping with actual parking lines on the ground.
2Loss of information
If multiple lines (center line, center limit lines, vehicle moving line) are superimposed on video data, then the visual representation of parking space and vehicle path is clear, but the device complexity increases
Solution Approach 1:
The patent uses a single video imaging device to capture the rearward scene, and the same device's output is used for both displaying the actual parking lines (when visible) and superimposing multiple guidance lines. This multi-functional use of the video data reduces the need for additional sensors or complex hardware while achieving comprehensive guidance information.
Solution Approach 2:
The patent combines multiple guidance functions (center indication, boundary indication, path prediction) into a single superimposed video display. Rather than using separate devices for each function, all guidance information is merged into one composite visual presentation that the driver views through a single display interface, simplifying the overall system architecture.

AI summary
A display control device includes a video data acquisition unit (120) that acquires video data from a camera that captures a video in a moving direction of a vehicle, a parking line recognition unit (130) that recognizes a parking line being a line of a parking space from the video data, a center line generation unit (140) that generates a center line of the parking space from the recognized parking line, a vehicle moving line generation unit (110) that generates a vehicle moving line extending in the moving direction of the vehicle from a position corresponding to a center part along a width of the vehicle, a superimposed video generation unit (150) that generates superimposed data being video data where the center line and the vehicle moving line are superimposed on the video data, and a display control unit (160) that transmits the superimposed data to a display unit so as to display a video related to the superimposed data on the display unit.
