==IN-VEHICLE COMMUNICATION SYSTEM, DATA STRUCTURE OF REPROGRAMMING POLICY METADATA, AND DATA STRUCTURE OF DOWNLOAD METADATA - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18389895 titled 'IN-VEHICLE COMMUNICATION SYSTEM, DATA STRUCTURE OF REPROGRAMMING POLICY METADATA, AND DATA STRUCTURE OF DOWNLOAD METADATA

==Simplified Explanation==

The abstract describes an in-vehicle communication system that allows for the transmission of update data from a center device to a target device installed in a vehicle, via a master device. The center device sends reprogramming policy metadata to the master device, which then requests download metadata and updates the target device accordingly.

* Center device transmits update data to target device
* Master device receives update data as a distribution package and transfers it to the target device
* Target device writes the update data into storage
* Center device sends reprogramming policy metadata to master device
* Master device requests download metadata from center device
* Master device interprets download metadata, acquires necessary data, and updates target device

== Potential Applications ==
The technology described in the patent application could be used in various industries such as automotive, transportation, and communication systems.

== Problems Solved ==
This technology solves the problem of efficiently updating electronic control units installed in vehicles without the need for manual intervention.

== Benefits ==
The benefits of this technology include faster and more reliable updates to vehicle systems, reducing downtime and improving overall performance.

== Potential Commercial Applications ==
The technology could be commercially applied in the automotive industry for updating vehicle software, as well as in other industries that require remote data transfer and control.

== Possible Prior Art ==
One possible prior art could be similar systems used in the automotive industry for updating software in vehicles remotely.

=== What is the specific technology used for data transfer in this system? ===

The specific technology used for data transfer in this system is not explicitly mentioned in the abstract. However, it can be inferred that the system likely utilizes wireless communication protocols or wired connections to transfer data between the center device, master device, and target device.

=== How does this technology ensure data security during the update process? ===

The abstract does not provide specific details on how data security is ensured during the update process. However, it can be assumed that the system may incorporate encryption protocols, authentication mechanisms, and secure data transfer protocols to protect the update data from unauthorized access or tampering.


==Original Abstract Submitted==

An in-vehicle communication system includes a center device that transmits update data to a target device as an electronic control unit installed in a vehicle, a master device that is installed in the vehicle, receives the update data as a distribution package, and transfers the update data to the target device, and the target device that writes the update data transferred from the master device into a storage portion. The center device transmits reprogramming policy metadata to the master device. The master device requests the center device for download metadata. The master device interprets the download metadata, acquires necessary data, and perform data update control of the target device.
