Vehicle Camera Signal Strength Feedback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in adjusting wireless vehicle cameras without convenient feedback on signal strength, leading to potential signal dropout during maneuvers, especially when infotainment systems do not provide a signal strength indicator.
Innovation Solution
A system that includes a vehicle with a first communication module connected to a wireless camera and a second communication module connected to a mobile device, which determines the signal strength and transmits a metric of transmission quality to the mobile device, providing feedback on camera placement and ensuring sufficient signal strength for video transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless camera is used to enable flexible placement, then adaptability is improved, but signal reliability deteriorates due to potential signal dropout during maneuvers
Solution Approach 1:
The system continuously monitors signal strength between the wireless camera and vehicle antenna, providing real-time feedback to the driver through visual indicators. This feedback mechanism allows the driver to adjust camera placement to maintain adequate signal strength, resolving the contradiction between placement flexibility and signal reliability.
2Measurement precision
If driver checks signal strength by entering vehicle cabin, then measurement precision is improved, but ease of operation deteriorates due to inconvenient repeated checks
Solution Approach 1:
The system uses an intermediary indicator mechanism that provides signal strength information externally visible to the driver. This intermediary allows accurate signal assessment without requiring the driver to enter the vehicle cabin, maintaining measurement precision while dramatically improving ease of operation.
3Ease of operation
If signal strength indicator is provided on infotainment system, then ease of operation is improved, but reliability deteriorates when infotainment system does not provide indicator
Solution Approach 1:
The system provides signal strength indicators before the driver attempts to use the camera during critical maneuvers. This preliminary feedback allows the driver to adjust camera placement in advance to ensure adequate signal strength, preventing signal dropout during important operations rather than reacting after problems occur.
Data Source
AI summary
Method and apparatus are disclosed for vehicle camera signal strength indicator. An example vehicle includes a first communication module, a second communication module, and a hardware module with a processor and memory. The first communication module communicatively couples to a wireless camera. The second communication module communicatively couples to a mobile device. The second communication module is different than the first communication module. The hardware module (i) determines a metric of transmission quality based on a signal strength from the wireless camera, and (ii) sends the metric of transmission quality to the mobile device to provide feedback regarding a placement of the wireless camera on the vehicle.
