Automotive Data Replication for Error-Free Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods in automobiles are inadequate for ensuring reliable and error-free data integrity, particularly due to the lack of dynamic packet switching and the inefficiency of redundant data replication, which often results in corrupted replacement data.
Innovation Solution
A system arrangement that replicates and redundantly transmits data early in the processing chain, using a physical application device and a cell multiplexing device to package data into cells with forward error corrections, ensuring that substitute data can be used if the primary data is faulty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted redundantly in conventional systems, then replacement data is available, but the replacement data may be corrupted and technical effort increases
Solution Approach 1:
The patent applies preliminary action by performing data replication at the application device before transmission, creating multiple identical data streams that are then distributed through different physical paths. This early replication ensures that valid replacement data is already available at the receiving end without requiring complex post-transmission error handling
Solution Approach 2:
The patent segments the data transmission system into distinct functional components: the application device that replicates data, the physical layer that transports it, and the receiving device that verifies and selects valid data. This segmentation allows each component to be optimized independently, reducing overall system complexity
2Adaptability or versatility
If packet-switched transmission is used, then dynamic routing is possible, but latency requirements are not met and technical effort increases
Solution Approach 1:
The patent extracts the dynamic routing function from the transmission medium itself and implements it at the application layer through data replication. Instead of dynamically switching packets during transmission, the system creates multiple static paths in advance, eliminating the need for mid-transmission routing decisions and reducing latency
Solution Approach 2:
The patent inverts the conventional approach by moving the adaptability function from the network layer (dynamic packet switching) to the application layer (data replication). This inversion allows the physical transmission layer to remain simple and fast while the application layer provides the necessary flexibility through redundant data streams
3Reliability
If redundant data replication is performed, then replacement data is available, but network load increases without added value
Solution Approach 1:
The patent applies local quality by making the data replication transparent and localized to the application device. The redundant data streams are created locally and transmitted through existing physical infrastructure without requiring additional network resources or increasing overall network load

AI summary
The present invention is directed to a system arrangement which generates substitute data which can be used if transmitted data is negatively verified, i.e. if it is identified as being faulty. According to the invention, data is replicated and transmitted redundantly at a particularly suitable location and is coded accordingly. In the special combination of features, various security mechanisms are integrated and synergistically linked in such a way that particularly secure data transmission in the automobile is guaranteed. The present invention specifically addresses the security requirements and hardware conditions in the, which is not the case, for example, with packet-switched communication. The coding makes it possible for the receiver to detect that there may be an error regarding the data integrity or that data was transmitted incorrectly or not at all.If this is detected, the redundantly transmitted data can be accessed at the receiver end, and the data transmission is not impaired overall. The present invention is further directed to a correspondingly configured method that enables the system arrangement to be provided or operated. Furthermore, a computer program product is proposed, with control commands that execute the method or provide or operate the system arrangement.
