Solution Overview

Problem

Current vehicle monitoring systems fail to provide a clear and coherent view of entrance and loading areas, leading to misjudgments by drivers, which can result in accidents due to the lack of direct insight into these areas, as existing systems either show the interior or exterior but not both simultaneously without significant changes in scale and perspective.

Innovation Solution

The implementation of at least one interior camera and one exterior camera that capture partial areas of the vehicle interior and exterior, with image streams displayed on a common display device, transformed to maintain consistent scale and perspective, allowing the vehicle driver to recognize transitions between areas, and optionally enhanced with night-vision capabilities and 360-degree views, with a vehicle contour displayed to distinguish between interior and exterior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If mirrors or camera display systems are used to make entrance and loading areas visible, then the driver's insight into these areas is improved, but misjudgments occur due to unclear situations when passengers get on and off or when loading and unloading

Engineering Contradiction:
Improveinsight into entrance and loading areasVSAvoidassessment accuracy
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent segments the vehicle monitoring system into distinct functional zones: an interior area captured by interior cameras, an exterior area captured by exterior cameras, and a boundary area that shows the transition zone. The display device presents these segmented views in a coordinated manner that maintains spatial continuity, allowing the driver to clearly assess the situation at entrance and loading areas without confusion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides continuous visual feedback to the driver about the status of entrance and loading areas. The unified display shows real-time image streams from both interior and exterior cameras, enabling the driver to monitor passenger movement and loading operations continuously and make informed decisions about when it is safe to close doors or proceed with vehicle operations.

Inventive Principle:
Principle #23Feedback

2Area of stationary object

If multiple cameras are used to capture both interior and exterior areas, then the coverage is improved, but the device complexity increases

Engineering Contradiction:
Improvecoverage areaVSAvoidnumber of cameras and processing systems
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by using the same display device and evaluation device to process and present both interior and exterior camera feeds simultaneously. The system is designed to handle multiple image streams from different cameras and combine them into a single unified view, reducing the need for separate dedicated systems for interior and exterior monitoring and thereby reducing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Method, in a vehicle with an interior camera arrangement and an exterior camera arrangement, wherein at least one interior camera (13, 14, 28) and at least one exterior camera (11, 12, 15, 16, 17, 29) are provided for recording an image stream to depict the vehicle interior and the vehicle exterior, wherein the interior camera (13, 14, 28) captures at least a part of the vehicle interior and the exterior camera (11, 12, 15, 16, 17, 29) captures at least a part of the vehicle exterior.It is provided that the at least one interior camera (13, 14, 28) and the at least one exterior camera (11, 12, 15, 16, 17, 29) capture at least partial areas of the vehicle interior and the vehicle exterior and transmit these to a display device (19), wherein the partial areas are at least partially adjacent to one another, preferably adjacent to one another in such a way that the display by means of the display device (19) on at least one screen (18, 18', 31) is scaled and perspectively such that the display areas of the vehicle interior and the vehicle exterior are shown at least at the adjacent parts without any recognizable change in scale and perspective.
