Patent ID: 7386714

Claim:
An electronic control unit comprising: a plurality of processing units, including a first processing unit and at least one second processing unit, wherein the first processing unit reads out a correction value from a storage unit and transmits the correction value to the second processing unit, and the first processing unit and the second processing unit correct input and output signals based on the correction value, wherein the first processing unit and the second processing unit respectively include a communication unit that performs reception and transmission of the correction value, wherein each of the communication units includes a buffer-for-startup that is used at a time of startup of a corresponding processing unit and stores the correction value at the time of the startup; and a buffer-for-normal processing that is used after the startup of the processing units and stores the correction value after the startup, wherein the correction value transmitted from the buffer-for-startup of the first processing unit to the buffer-for-startup of the second processing unit is a correction value at the time of startup of the first and second processing units.
