Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle vision systems lack the ability for drivers to freely and intuitively control the virtual viewing position and angle, which limits their effectiveness in providing optimal views for various driving conditions and hazards.
Innovation Solution
A vehicle vision system that utilizes depth segmented 2D layer coulisses and gesture detection technology, allowing drivers to manually adjust the virtual viewpoint in real-time through a touch screen interface, enabling flexible control of the viewing angle and position using gestures and haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed virtual viewing position and angle are used in the vision system, then the system structure is simple, but the adaptability to different driving conditions and hazards is limited
Solution Approach 1:
The patent implements dynamic adjustability of the virtual viewing position and angle through a touch screen interface. The system transitions from a fixed viewing configuration to one where drivers can freely move the virtual camera position and orientation by touching and dragging specific regions on the display, allowing adaptation to various driving scenarios such as reversing, parking, and general maneuvering.
Solution Approach 2:
The touch screen serves as an intermediary between the driver and the vision system's virtual camera parameters. Through the touch interface, drivers can indirectly control the virtual viewing position and angle without complex manual adjustments or multiple physical controls, simplifying the interaction while enhancing adaptability.
2Adaptability or versatility
If pre-set viewing positions are provided, then the ease of operation is improved, but the ability to provide optimal views for various driving conditions is limited
Solution Approach 1:
The system enables drivers to self-adjust the virtual viewing parameters directly through intuitive touch gestures on the screen. By allowing drivers to freely drag and position the virtual camera view themselves, the system provides personalized optimal views for each driver's specific needs and driving conditions, enhancing both adaptability and ease of operation.
Solution Approach 2:
The touch screen provides immediate visual feedback as drivers interact with the virtual viewing controls. When drivers touch and drag the display to adjust the virtual camera position, the system实时更新 the displayed image accordingly, allowing drivers to intuitively understand the relationship between their gestures and the resulting view changes.
3Reliability
If manual adjustment of virtual viewpoint is allowed, then the detection of hazards is improved, but the device complexity increases
Solution Approach 1:
The touch screen interface serves multiple functions: it displays the composite image from multiple cameras, provides control for adjusting virtual viewing parameters, and delivers haptic feedback to confirm driver input. This multi-functionality allows the system to enhance hazard detection capability through manual viewpoint adjustment without adding separate complex control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances driver assistance by providing customizable and intuitive control over the virtual view, improving the detection and awareness of hazards and objects during driving maneuvers, such as reversing and parking.
Implementation Method 1
The control is responsive to a touch screen or a gesture interface or touch sensitive user input that detects a touch or approach of a driver's finger
Implementation Method 2
The touch screen may have actuators for applying a haptic feedback to the driver's touch inputs

AI summary
A vehicular vision system includes a plurality of cameras disposed at a vehicle and having respective exterior fields of view, and a display screen for displaying images derived from captured image data in a surround view format where captured image data is merged to provide a single composite display image from a virtual viewing position. A control includes a processor that processes image data captured by the cameras to detect an object present in the field of view of at least one of the cameras. During a driving maneuver of the vehicle, the display screen displays surround view video images and responsive to detection of the object, the display screen displays an enlarged view of the detected object.
