Parking Start Frame Guidance for Bird's Eye View Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assistance systems do not clearly indicate where a driver should start the parking operation to reach a target parking position without performing a steering maneuver, making it difficult for inexperienced drivers to park their vehicles effectively.
Innovation Solution
A parking assistance apparatus that uses multiple on-board cameras to create a bird's eye image, displaying a target parking frame and a parking start frame, which changes position and color based on the vehicle's steering angle, helping drivers recognize the optimal starting point for parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional parking assistance system displays only the current vehicle position and target parking position, then the system complexity is low, but the driver cannot clearly understand where to start the parking operation
Solution Approach 1:
The system calculates and displays the parking start position in advance before the driver begins the parking maneuver. This preliminary information provides the driver with clear guidance on where to start the parking operation, eliminating the information gap without requiring complex real-time control systems.
Solution Approach 2:
The system adds a new dimension of information by displaying not only the current and target positions but also the intermediate parking start position. This creates a multi-stage guidance system that breaks down the parking process into manageable segments, improving driver understanding without overwhelming complexity.
2Adaptability or versatility
If the parking start frame is fixed in position and appearance, then the display system is simple, but it cannot adapt to different steering angles and parking scenarios
Solution Approach 1:
The parking start frame is designed to be dynamic rather than static. It automatically updates its position and drawing mode based on the vehicle's current steering angle, allowing the display to adapt to different parking scenarios and steering inputs without requiring complex manual adjustments.
Solution Approach 2:
The system implements feedback by continuously monitoring the steering angle and using this information to adjust the parking start frame's position and appearance. This closed-loop approach ensures the display remains accurate and relevant to the driver's current actions, enhancing adaptability with moderate complexity.

AI summary
A target parking position serving as a parking target of a vehicle is set, and a parking start position from which the vehicle can start to reach the target parking position while maintaining a predetermined steering angle is set. Then, a vehicle mark V indicating a current position, a target parking frame F1 indicating the target parking position, and a parking start frame F2 indicating the parking start position are drawn on a bird's eye image of a periphery of the vehicle, and a display device 5 is allowed to display an image in which the vehicle mark V, the target parking frame F1 and the parking start frame F2 are drawn on the bird's eye image. At this time, the parking start frame F2 is drawn on the bird's eye image so that a drawing mode thereof can be changed in response to a current steering angle of the vehicle.
