Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving aid display methods for motor vehicles, particularly during low-speed maneuvers like parking, are hindered by predetermined image arrangements and conflicting orientations between bird's eye views and larger-scale images, leading to user confusion.
Innovation Solution
A method that dynamically generates a 3D scene based on varying vehicle viewpoints, incorporating a 3D model and virtual screens representative of camera angles, allowing users to select or automatically determine the best view for real-time obstacle detection and environment understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If predetermined image arrangements are used on the dashboard screen, then the display structure is simple and easy to implement, but the user understanding of the vehicle environment is disturbed and parking maneuverability is hindered
Solution Approach 1:
The patent applies dynamics by making the display configuration adaptive rather than fixed. The system dynamically adjusts the bird's eye view and larger-scale image display based on vehicle speed, steering angle, and maneuvering state. This allows the display to optimize user understanding of the vehicle environment for different driving conditions while maintaining a relatively simple underlying display structure that can be controlled through software parameters.
Solution Approach 2:
The patent changes display parameters (such as image size, position, and orientation) based on vehicle operating conditions. By modifying these parameters dynamically according to speed, steering angle, and maneuvering state, the system improves user understanding without requiring a completely complex display architecture, thus resolving the contradiction between ease of operation and device complexity.
2Area of stationary object
If contradictory orientations of bird's eye view and larger-scale images are displayed simultaneously, then the screen utilization is maximized, but the correct understanding of the vehicle environment is disturbed
Solution Approach 1:
The patent applies local quality by providing different display orientations and configurations for different regions of the screen based on the specific maneuvering context. Instead of using a single fixed orientation for all images, the system adjusts the orientation and presentation of each image region according to its purpose and the current driving situation, thereby maintaining screen utilization while preventing environmental understanding confusion.
Solution Approach 2:
The system dynamically adjusts the orientation and positioning of different image regions on the screen based on vehicle state. During normal driving, one configuration is used; during parking maneuvers, another configuration is applied. This dynamic adaptation allows the screen to be fully utilized while ensuring that image orientations consistently support accurate environmental understanding for the current maneuver type.
3Adaptability or versatility
If multiple cameras with fixed viewpoints are used, then the system structure is simple, but the adaptability to different driving situations and obstacle detection is limited
Solution Approach 1:
The patent makes the camera viewpoint selection dynamic rather than fixed. The system automatically selects and switches between different camera viewpoints based on detected driving situations such as parking maneuvers, obstacle detection, and normal driving. This dynamic viewpoint selection provides high adaptability to different driving situations while maintaining a relatively simple fixed camera hardware structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The system performs self-service by automatically selecting appropriate camera viewpoints and display configurations based on its own sensor data without requiring manual user input. The control unit monitors vehicle state and autonomously adjusts the display system, providing adaptability to different driving situations while keeping the overall system structure simple and automated.
