Collecting Big Data from Automotive ECUs beyond the CAN Bandwidth for Fault Visualization

Algorithm 3

Algorithm of the transfer agent.

Input:

   RP - Data request packet from data collector

    - Operation cycle of system main task

    - The time required for sending one CAN message

    - The size of data that can be stored in one CAN message

   OCC - CAN bus occupancy of the existing operation

Output:

   CIP - Cascading information packet to data collector

   DP - Data transfer packet to data collector
