Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack the ability to provide remote control functionality and ensure passenger safety when a third party is controlling the vehicle, especially with varying network conditions, which can affect data transmission and reception latency and bandwidth.
Innovation Solution
An electronic control unit within the vehicle that receives control commands from external user input units, measures communication service quality, selects appropriate cameras, and transmits images and control commands to vehicle devices, allowing remote control while managing speed and image resolution based on service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control functionality is implemented with high data transmission requirements, then control capability is improved, but network latency and bandwidth consumption increase
Solution Approach 1:
The system dynamically changes transmission parameters including image resolution, frame rate, and compression level based on network conditions. When network latency is high or bandwidth is limited, the electronic control unit reduces image quality parameters to maintain responsive remote control while adapting to network constraints
Solution Approach 2:
The system implements dynamic adaptation by continuously monitoring network status and adjusting control parameters in real-time. The electronic control unit modifies transmission frequency, data format, and image resolution dynamically based on current network conditions, transforming a static system into one that responds to changing environmental factors
2Measurement precision
If high resolution images are transmitted continuously, then monitoring quality is improved, but bandwidth consumption increases
Solution Approach 1:
The electronic control unit adjusts image transmission parameters including resolution, format, and compression ratio based on network bandwidth availability. When bandwidth is sufficient, high-resolution images are transmitted for superior monitoring quality. When bandwidth is limited, the system automatically reduces image parameters to maintain acceptable quality while conserving network resources
Solution Approach 2:
The system transmits only the necessary portion of visual information based on current needs. Instead of continuously transmitting full-resolution images from all cameras, the electronic control unit selectively transmits images from specific cameras at specific resolutions based on what is currently needed for monitoring, reducing overall data volume while maintaining effective surveillance
3Area of stationary object
If multiple cameras are activated simultaneously, then field of view coverage is improved, but power consumption increases
Solution Approach 1:
Instead of activating all cameras simultaneously, the electronic control unit activates only the subset of cameras necessary to achieve adequate monitoring coverage based on current vehicle context and network conditions. The system determines the minimum required camera set to maintain safety monitoring while conserving power
Solution Approach 2:
The system dynamically adjusts which cameras are active based on real-time conditions including vehicle speed, network bandwidth, and monitoring requirements. The electronic control unit can switch between different camera configurations, activating more cameras when coverage is critical and fewer cameras when power conservation is prioritized, creating a flexible adaptive monitoring system
