UPDATING SYSTEM, ELECTRONIC CONTROL UNIT, UPDATING MANAGEMENT DEVICE, AND UPDATING MANAGEMENT METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18603093 titled 'UPDATING SYSTEM, ELECTRONIC CONTROL UNIT, UPDATING MANAGEMENT DEVICE, AND UPDATING MANAGEMENT METHOD

The abstract describes an updating system that involves electronic control units and an updating management device. The management device requests updates from the control units, stores update results, and triggers control using the updated programs.

  • Electronic control units update programs and store results
  • Control units have first and second storage regions
  • Updated programs stored in second region
  • Control units notify management device of update results
  • Control units start predetermined control using updated program
  • System ensures completion of program updates in control units

Potential Applications: - Industrial automation systems - Automotive control units - Smart home devices - Medical equipment control

Problems Solved: - Ensures all control units are updated with the latest programs - Streamlines the updating process for multiple units - Reduces the risk of outdated programs causing malfunctions

Benefits: - Improved system performance - Enhanced security through up-to-date programs - Simplified management of program updates

Commercial Applications: Title: "Efficient Updating System for Electronic Control Units" This technology can be applied in various industries such as manufacturing, automotive, healthcare, and smart home sectors. It can streamline the updating process for control units, ensuring optimal performance and reducing the risk of system malfunctions.

Questions about Updating System for Electronic Control Units:

1. How does the system ensure the completion of program updates in all electronic control units? The system ensures completion by storing update results and triggering control using the updated programs.

2. What are the potential risks of not updating the programs in electronic control units? Not updating the programs can lead to system malfunctions, security vulnerabilities, and performance issues.


Original Abstract Submitted

An updating system includes a plurality of electronic control units and an updating management device. The updating management device is configured to request that the electronic control units respectively update programs and store update results of the programs transmitted from the electronic control units. The electronic control unit has a first storage region and a second storage region, and is configured to store an updated program in the second storage region and notify the updating management device of the update results according to a request from the updating management device, and is configured to start a predetermined control using the updated program stored in the second storage region when the update results stored in the updating management device indicate that the updating of the programs in the electronic control units is completed.
