Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of vehicle electrical systems in transportation means, with numerous control devices and switches, leads to increased energy consumption, reduced ranges, and communication problems due to unclear architecture and lack of knowledge among developers, making troubleshooting difficult.
Innovation Solution
A method for communication between control devices in transportation means, where a first control device sends a request to a second device that does not react, and an external instance automatically adapts a data set to reestablish communication by influencing the second device's behavior, using a self-learning algorithm to supply energy and reestablish communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of control devices is increased to handle various functions, then the functional capability is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The system segments control devices into active and inactive states, with a segmentation controller managing the division of functional responsibilities. This allows the system to maintain high adaptability while reducing the effective complexity by organizing numerous control devices into manageable segments that can be activated or deactivated as needed.
Solution Approach 2:
The segmentation controller serves multiple functions: it manages active control devices, activates inactive ones, handles communication routing, and adapts data sets. This multi-functionality reduces the need for separate specialized components, thereby improving functional capability without proportionally increasing device complexity.
2Speed
If all control devices are kept in active communication status, then the communication responsiveness is improved, but the energy consumption increases
Solution Approach 1:
The system dynamically adjusts the active/inactive status of control devices based on current operational needs. The segmentation controller can activate or deactivate control devices in real-time, allowing the system to maintain fast communication responsiveness for active devices while conserving energy by keeping less critical devices inactive until needed.
Solution Approach 2:
The segmentation controller automatically manages the activation and deactivation of control devices based on system state and communication requirements, without requiring manual intervention. This self-service mechanism ensures energy efficiency while maintaining communication responsiveness by autonomously optimizing which devices remain active.
3Loss of energy
If control devices are deactivated to save energy, then the energy consumption is reduced, but the communication reliability deteriorates
Solution Approach 1:
The segmentation controller maintains a registry of inactive control devices and their capabilities in advance. When communication is needed, the controller can quickly activate appropriate inactive devices based on pre-stored information, ensuring communication reliability is restored promptly while having minimized energy consumption during inactive periods.
Solution Approach 2:
The system implements feedback mechanisms where the segmentation controller monitors communication needs and system state, then adjusts the active/inactive status of control devices accordingly. This feedback loop ensures that devices are activated in response to actual communication requirements, maintaining reliability while optimizing energy consumption by keeping devices inactive when not needed.
4Ease of repair
If the architecture is made more detailed to improve system clarity, then the troubleshooting capability is improved, but the device complexity increases
Solution Approach 1:
The segmentation controller acts as an intermediary that provides a simplified view of the complex control device architecture. It manages the detailed configuration and state of numerous control devices while presenting a unified interface for troubleshooting and control, thereby improving troubleshooting capability without requiring end users to directly interact with the full complexity of the underlying architecture.
Data Source
AI summary
Methods, systems, and apparatuses are provided for communication between electronic control devices for a transportation vehicle. A request is sent by a first electronic control device to a second electronic control device. The second electronic control device is determined to not react to the request in response. A data set assigned to the second electronic control device is automatically adapted. The data set is automatically written on an instance located outside the second electronic control device. The data set is applied in the instance to initiate a reaction of the second electronic control device to the request.
