First onboard ecu, program, information processing method, and onboard system

A program for causing a computer that is communicably connected to an onboard apparatus mounted in a vehicle and a second onboard ECU that outputs information regarding control of the onboard apparatus, to perform processing for:

• sequentially obtaining a plurality of pieces of information regarding control of the onboard apparatus that are output from the second onboard ECU;
• buffering, in a predetermined storage region, the sequentially obtained pieces of information;
• and
• performing processing related to driving of the onboard apparatus based on the information buffered in the predetermined storage region,
• wherein the plurality of pieces of information buffered in the predetermined storage region include information to be used later than information that is used at the present point in time.

An onboard system that includes a first onboard ECU that is directly connected to an onboard apparatus and a second onboard ECU that is communicably connected to the first onboard ECU,

• wherein the second onboard ECU generates a plurality of control signals for controlling the onboard apparatus based on predetermined curve information for control, and
• sequentially outputs the generated control signals to the first onboard ECU,
• the first onboard ECU sequentially obtains the control signals output from the second onboard ECU,
• buffers, in a predetermined storage region, the sequentially obtained control signals,
• generates a drive signal for driving the onboard apparatus based on information buffered in the predetermined storage region, and
• sequentially outputs the generated drive signals to the onboard apparatus, and
• the plurality of control signals buffered in the predetermined storage region include a control signal to be used later than a control signal that is used at the present point in time.
