CENTER, CONTROL METHOD, AND NON-TRANSITORY STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18322900 titled 'CENTER, CONTROL METHOD, AND NON-TRANSITORY STORAGE MEDIUM

Simplified Explanation

The abstract describes a center that communicates with an OTA master to control software updates for a vehicle's electronic control unit (ECU).

  • The center has processors that determine if permission frames are available when a software update request is received from the OTA master.
  • If permission frames are available, the center allocates one to the OTA master and allows the update process to proceed.
  • The processors also determine if multiplex frames are available when a transmission request for the update package is received.
  • If multiplex frames are available, the center allocates one to the OTA master and controls the transmission of the update package.


Original Abstract Submitted

A center that is configured to communicate with an Over-The-Air (OTA) master that controls software update for an electronic control unit mounted on a vehicle is provided. The center includes one or more processors configured to determine availability of permission frames when an inquiry for software update is received from the OTA master and update data for the electronic control unit exists, and, when at least one of the permission frames is available, allocate the permission frame available among the permission frames to the OTA master and permit update processing. The one or more processors are configured to determine availability of a multiplex frame when a transmission request for the distribution package is received from the OTA master, and, when at least one of the multiplex frames is available, allocate a multiplex frame available among the multiplex frames to the OTA master and control transmission of the distribution package.
