Vehicle Controller Switching Between RF and Infrared Fueling Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle controller technologies face challenges in selecting the most appropriate communication method between vehicles equipped with both first and second communication devices and energy supply devices, which are either equipped with both types of communication devices or only the second communication device, leading to inefficiencies in energy supply and communication during hydrogen or natural gas filling.
Innovation Solution
The vehicle controller prioritizes energy supply through the first communication device over the second, attempting communication via the first device initially and switching to the second if no response is received, with periodic checks to adapt communication methods based on the energy supply device's capabilities, ensuring bidirectional communication is used when available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle controller always uses the first communication device for energy supply communication, then communication reliability is improved, but compatibility with energy supply devices equipped with only the second communication device deteriorates
Solution Approach 1:
The vehicle controller dynamically selects the communication device based on the energy supply device's capabilities. When the first communication device is available and responsive, it is used for bidirectional communication. When only the second communication device is available or the first device does not respond, the controller automatically switches to the second device, ensuring compatibility while maintaining optimal communication performance.
2Productivity
If the vehicle controller attempts communication with the first communication device before the second, then communication efficiency is improved, but communication time delay increases when the first device is unavailable
Solution Approach 1:
The vehicle controller performs a preliminary communication attempt with the first communication device before initiating energy supply. This preliminary action allows the system to identify available communication methods in advance, ensuring that the most efficient communication channel is used without causing time delays during the actual energy supply process.
3Adaptability or versatility
If the vehicle controller supports multiple communication methods, then adaptability to different energy supply devices is improved, but device complexity increases
Solution Approach 1:
The vehicle controller is designed with multi-functionality to support both first and second communication devices. This universal design allows the same controller to adapt to different energy supply device configurations without requiring separate specialized controllers, thereby managing complexity while maintaining high adaptability.

AI summary
The vehicle controller is programmed to make a communication attempt from the first communication device to an energy supply device when the energy supply device supplies energy to the energy storage device from an external energy supply device; supply energy with communication between the first communication device and the energy supply device when a response is received from the energy supply device to the communication attempt; and supply energy with communication between the second communication device and the energy supply device when no response is received from the energy supply device to the communication attempt.
