Abstract

An ECU is provided with a microcomputer for performing arithmetic operation for controlling a control target by executing a program stored in a ROM and for performing the process to transmit the control data calculated by means of the arithmetic operation to a communication target. The program comprises independent program modules, that is, a program (application unit) for performing the arithmetic operation, a program (communication conversion unit) for extracting the control data to be transmitted from among the control data calculated by the application unit and for performing the process to convert the extracted control data to the communication data string corresponding to the communication protocol of the communication target, and a program (communication driver unit) for performing the process to transmit the data string according to the communication protocol.
