Parking Assist System with Overlay Trajectory Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems lack intuitiveness and effectiveness in guiding drivers to park vehicles safely, as they often rely on complex displays and insufficient visibility, leading to continued accidents despite the use of cameras and sensors.
Innovation Solution
A parking assist system that includes a camera unit, a display unit, and a processor unit generating and overlaying first and second parking guide lines, along with an estimated travel trajectory line based on steering angle information, to provide intuitive guidance for parking by overlaying these lines on the vehicle's front or rear view image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras and sensors are installed throughout the vehicle to improve visibility, then the coverage area increases, but the device complexity and cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single camera to perform multiple functions: capturing real-time images, generating trajectory lines, and providing parking guidance. The camera system is integrated with processing units that extract trajectory information and generate guidance lines, allowing one device to replace what would traditionally require multiple separate components (cameras, sensors, and processing units).
Solution Approach 2:
The patent merges the camera unit, trajectory extraction unit, and guidance line generation unit into an integrated parking assistance system. The camera captures images that are simultaneously processed for both real-time display and trajectory analysis, combining multiple functions into a unified system that reduces overall complexity while maintaining comprehensive coverage.
2Loss of information
If complex display devices are used to show parking information, then the information completeness improves, but the ease of operation and intuitiveness deteriorate
Solution Approach 1:
The patent segments parking guidance information into distinct visual elements: real-time camera images, trajectory lines showing vehicle path, and guidance lines indicating parking targets. These segmented elements are overlaid on the display, allowing drivers to quickly identify specific information (trajectory vs. target position) without being overwhelmed by a complex unified display.
Solution Approach 2:
The patent uses color differentiation to enhance intuitiveness, displaying trajectory lines and guidance lines in distinct colors on the screen. This allows drivers to immediately distinguish between different types of information (current path vs. target position) at a glance, improving ease of operation while maintaining complete information display.
3Ease of operation
If simple trajectory display is provided based on steering direction, then the ease of operation improves, but the measurement precision and accuracy of parking guidance deteriorate
Solution Approach 1:
The patent implements feedback by continuously capturing real-time images with the camera and dynamically updating the displayed trajectory lines based on actual vehicle movement and steering input. The system processes each frame to recalculate trajectory, providing continuous feedback to the driver about the actual vehicle path versus the intended parking target, thereby improving accuracy while maintaining ease of use through real-time visual feedback.

AI summary
Disclosed is a parking assist system including a camera unit for photographing front or rear view of a vehicle, and a display unit for displaying a front or rear view image of the vehicle photographed by the camera unit, the system characterized by: a processor unit generating a first and second parking guide line, one being perpendicular to the other, at an area which is apart from the vehicle by a predetermined distance, and generating an estimated travel trajectory line based on steering angle information obtained from a steering angle sensor of the vehicle; and an overlay unit for overlaying the photographed front or rear view image of the vehicle on the first and second parking guide lines and the estimated travel trajectory line.
