Autonomous Vehicle View Management for External Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of autonomous driving and parking systems face challenges in monitoring vehicle operations from outside the vehicle, as existing technologies do not provide a user-friendly method for real-time observation of autonomous driving or parking operations from external positions.
Innovation Solution
A system utilizing portable electronic devices wirelessly connected to the vehicle, with cameras installed at various positions, allows users to observe live videos of the vehicle's operations in real-time, featuring view-management algorithms that automatically select the most relevant camera views based on situational context, and provides additional information through video overlays.

Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are installed at different positions of the vehicle to capture comprehensive views, then the monitoring coverage is improved, but the device complexity and data processing load increase
Solution Approach 1:
The monitoring system is segmented into multiple independent camera units positioned at different locations on the vehicle (front, rear, side mirrors), each capturing specific zones. This segmentation allows comprehensive coverage while maintaining modular simplicity, where each camera unit can be independently selected and configured based on specific monitoring needs.
Solution Approach 2:
The system integrates multiple camera functions into a single unified platform that can capture live videos, record footage, transmit data wirelessly, and provide various viewing modes (live, recorded, selected). This multi-functional integration reduces overall system complexity by consolidating what would otherwise require separate systems for each function.
2Speed
If live videos from multiple cameras are transmitted to the portable device, then the real-time monitoring capability is improved, but the energy consumption and communication bandwidth increase
Solution Approach 1:
Instead of continuously transmitting all camera feeds at full resolution, the system transmits only selected or partially processed video streams based on monitoring priorities. The portable device can request specific views or receive reduced-resolution streams, consuming less energy and bandwidth while maintaining effective real-time monitoring capability.
Solution Approach 2:
The video transmission operates in periodic intervals rather than continuous streaming, with the system capturing and transmitting video frames at optimized intervals. This periodic transmission reduces energy consumption and communication bandwidth usage while maintaining the perception of real-time monitoring, as the intervals are short enough to provide timely updates.
3Ease of operation
If the user can select and view specific camera views on the portable device, then the ease of operation is improved, but the device complexity increases due to view-management requirements
Solution Approach 1:
The system provides automatic view selection and management features that operate without requiring complex user configuration. The portable device automatically receives and displays relevant video streams based on pre-configured preferences or current vehicle status, eliminating the need for users to manually manage complex view settings while maintaining ease of operation.
Solution Approach 2:
The system allows users to select from predefined view parameters (such as front view, rear view, side views) rather than requiring customization of complex camera settings. By changing only simple selection parameters rather than managing complex camera configurations, the system maintains ease of operation while reducing the effective complexity the user must deal with.
