Dynamic Bus System Configuration for Automotive Communication Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive bus systems have a static communication configuration that cannot adapt to new information or changes in communication requirements, limiting their ability to handle dynamic communication needs without significant investment or software updates.
Innovation Solution
A bus system and method that enable dynamic communication by incorporating devices and protocols allowing for the use of reserved identifiers or time windows for new messages, enabling communication of unknown information without altering existing static communications software, and optimizing priority and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static bus system configuration is used, then the system is simple and reliable, but it cannot adapt to new communication requirements or unknown information after the vehicle is introduced to the market
Solution Approach 1:
The patent implements a dynamic configuration mechanism that allows the bus system to adapt to new communication requirements after deployment. The configuration data is no longer fixed at manufacturing time but can be dynamically updated and modified in the field, enabling the system to respond to changing communication needs without hardware changes or complex reconfiguration procedures.
Solution Approach 2:
The patent changes the parameter of configuration from static to dynamic, allowing communication parameters such as message identifiers, routing information, and communication protocols to be modified after the system is introduced to the market. This enables adaptation to new requirements while maintaining the underlying static bus infrastructure.
2Adaptability or versatility
If the communication configuration is modified after the vehicle is introduced to the market, then adaptability improves, but software updates and reconfiguration are required which increases complexity and cost
Solution Approach 1:
The patent prepares the bus system in advance with the capability to dynamically update configuration data. The infrastructure for handling configuration changes is built into the system beforehand, including mechanisms for receiving, validating, and applying configuration updates without requiring full software reconfiguration or system shutdowns.
Solution Approach 2:
The bus system automatically handles configuration updates without requiring manual intervention or complex reconfiguration procedures. The system can self-update its communication parameters, routing tables, and protocol configurations based on received configuration data, reducing the need for manual software updates and simplifying the adaptation process.
3Productivity
If reserved identifiers or time windows are used for dynamic communication, then new messages can be transmitted without altering existing static communications software, but resource allocation becomes more complex
Solution Approach 1:
The patent segments the communication resources into reserved identifiers and time windows that are allocated for dynamic communication. These reserved resources are separated from the static communication configuration, allowing new messages to be transmitted using pre-allocated identifiers and time slots without modifying the existing static communications software or disrupting ongoing communications.
Solution Approach 2:
The patent adds a temporal dimension to resource allocation by introducing time windows for dynamic communication. In addition to reserved identifiers, specific time slots are allocated for transmitting new messages, creating a two-dimensional resource allocation scheme (identifier + time window) that enables dynamic communication without conflicting with static configuration.

AI summary
A bus system, a subscriber station, and a method for configuring a static bus system for a dynamic communication are provided. The bus system has at least two subscriber stations, a communications link for connecting the subscriber stations to each other, and at least one device for the dynamic communication between the subscriber stations of the bus system; the subscriber stations and the communications link are developed for the static communication, which is directed to messages to be transmitted on the bus system that are known when the bus system is made available and are configured according to specified transmitters and receivers, and the dynamic communication is directed to messages to be transmitted on the bus system that have become known only after the subscriber stations and the communications link have been made available and are configured according to specified transmitters and receivers.
