Bird's-Eye Vehicle Environment Display for Target Position Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle environment display systems, particularly for parking assistance, often provide distorted representations of the vehicle's surroundings, making it difficult for drivers to accurately compare virtual renderings with the real environment, especially when maneuvering to a target position.
Innovation Solution
A method and system that overlays real-time camera-based environmental sensing data with additional information layers to create a highly intuitive and optically corresponding representation of the vehicle's surroundings, including target positions, non-drivable areas, and obstacles, using a combination of camera and sensor data to enhance visibility and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera is mounted on the vehicle to capture images of the environment, then the driver can see the environment behind and to the sides of the vehicle, but the driver's attention is drawn away from the road
Solution Approach 1:
The system creates a virtual copy of the physical environment by capturing images with cameras and rendering them as a simulated viewable environment displayed on the head-up display. This allows the driver to perceive rear and side environments without physically turning their head or body, thus maintaining attention on the road while gaining environmental awareness.
2Speed
If the vehicle moves forward, then the vehicle reaches the target position, but the viewed environment becomes outdated and does not reflect the current position
Solution Approach 1:
The system pre-calculates and prepares environmental data for future positions along the planned path. As the vehicle approaches predetermined positions, the corresponding pre-captured images are activated and displayed, ensuring the viewable environment is always current without requiring real-time capture at every moment.
Solution Approach 2:
The system dynamically switches between different sets of captured images based on the vehicle's current position and movement state. As the vehicle moves forward along the path, the display transitions from images captured at earlier positions to images captured at later positions, maintaining synchronization between the viewed environment and actual vehicle position.
3Measurement precision
If images are captured at multiple positions along the path, then the environment can be accurately represented, but the data storage and processing requirements increase
Solution Approach 1:
The path is divided into multiple predetermined positions, and environmental data is captured and stored separately for each position. This segmentation allows the system to load and display only the relevant segment of environmental data corresponding to the vehicle's current position, rather than managing all data simultaneously, thus reducing memory requirements while maintaining accuracy.

AI summary
The invention relates to a method for: displaying an environment (16) of a vehicle (10), the vehicle (10) having a camera-based environment detection system (14) for detecting the environment (16) of the vehicle (10); and moving the vehicle (10) to a target position (24) in the environment (16). The method comprises the steps: providing images of the environment (16) of the vehicle (10) using the camera-based environment detection system (14); generating a bird's eye view of an environment image (26) based on the images of the environment (16) of the vehicle (10) provided using the camera-based environment detection system (14); determining at least one target position (24) in the environment (16) of the vehicle (10); displaying the at least one target position (24) in a first superimposition plane which covers the environment (16) of the vehicle (10); and superimposing the first superimposition plane on the environment image (26). The invention also relates to a corresponding driving assistance system (10) designed to perform the above method.
