Side-View Camera Display Layout for Faster Commercial Vehicle Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving assistance systems for commercial vehicles do not effectively provide an improved evaluation of driving situations, particularly due to challenging side view limitations and the need for increased driver attention, which can lead to safety and comfort issues during maneuvers like overtaking or reversing.
Innovation Solution
A driving assistance method and system that utilizes two side view cameras to capture images on opposite sides of a vehicle, with a display system within the cabin to simultaneously display these images on separate sections of a single screen, allowing the driver to evaluate both sides with minimal eye or head movement, and includes digital image processing to determine driving assistance conditions such as time to collision, safe or collision status, lane change status, event detection, and articulation angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple side view cameras are used to monitor both sides of the vehicle, then the coverage of the vehicle environment is improved, but the complexity of the display system increases
Solution Approach 1:
The patent combines images from multiple side view cameras (first side view camera and second side view camera) into a single display system with multiple display sections. This merging approach allows comprehensive coverage of both vehicle sides while maintaining a unified display interface, reducing the complexity that would arise from multiple separate display systems.
Solution Approach 2:
The display system is segmented into multiple display sections, where each section displays images from specific cameras. This segmentation allows the system to handle multiple camera inputs systematically, organizing the complex information into manageable sections that can be processed and displayed efficiently.
2Ease of operation
If side view images are displayed on separate display systems, then the information is organized by vehicle side, but the driver requires more eye movement to perceive both sides
Solution Approach 1:
The patent merges images from both vehicle sides into a single display system with multiple display sections. This allows the driver to view both side views in one location, eliminating the need to shift attention between separate display systems while maintaining clear organization of information by vehicle side through distinct display sections.
3Area of stationary object
If cameras are mounted to provide extensive side views for commercial vehicles, then the side view coverage is improved, but the driver's ability to quickly evaluate both sides increases difficulty
Solution Approach 1:
The patent transitions from a spatial distribution of display systems (separate displays for each side) to a dimensional reorganization within a single display system (multiple display sections in one location). This dimensional change allows comprehensive side view coverage to be presented in a consolidated format, making evaluation easier by reducing the physical distance the driver's gaze must travel.
