Autonomous Communication Module for Vehicle Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in vehicles often require a bridge device for communication between a controller and another device, leading to potential delays due to non-permanent communication connections.
Innovation Solution
A communication module with a first and second communication interface, memory, and processing unit, which receives an instruction message, saves a reference inquiry and inquiry response instruction, and independently responds to corresponding inquiry messages without needing to forward inquiries to the first device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bridge device is used for communication between controller and second device, then communication capability is improved, but communication delay increases due to non-permanent connections
Solution Approach 1:
The bridge device stores inquiry response instructions in advance in its memory, associated with reference inquiries. When an inquiry is received, the bridge device directly transmits the corresponding stored response instruction to the controller without needing to forward the inquiry first and wait for a response. This preliminary storage of response instructions eliminates the waiting time and reduces communication delay while maintaining reliable communication capability.
2Measurement precision
If inquiry messages are forwarded to first device for response, then communication accuracy is improved, but communication speed deteriorates
Solution Approach 1:
The bridge device pre-stores inquiry response instructions in its memory, associated with reference inquiries. When an inquiry message is received, the bridge device directly transmits the corresponding stored response instruction to the controller, eliminating the need to forward the inquiry and wait for a response. This approach maintains communication accuracy by ensuring the correct response is transmitted while significantly improving communication speed by removing the round-trip delay.
Solution Approach 2:
The bridge device creates and stores copies of inquiry response instructions in its memory, associated with reference inquiries. Instead of forwarding the original inquiry and waiting for a response, the bridge device uses these pre-stored copies to directly transmit the appropriate response instruction to the controller. This copying mechanism ensures accurate response transmission while eliminating communication delays.
3Reliability
If bridge device stores and processes communication data, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The bridge device stores inquiry response instructions in advance in its memory, associated with reference inquiries. This preliminary action allows the bridge device to directly transmit the corresponding stored response instruction when an inquiry is received, without needing to forward the inquiry and wait for a response. This approach improves communication reliability by ensuring the correct response is transmitted while keeping the device complexity relatively low, as the bridge device only needs to store and retrieve pre-prepared response instructions rather than implementing complex communication protocols.
