摘要

PROBLEM TO BE SOLVED: To provide a multiplexing control device capable of avoiding the inconsistency of control arithmetic results among control devices resulting from the use of a plurality of control logics.SOLUTION: A plurality of control units provided in a multiplexing control device is configured to execute a plurality of arithmetic elements constituting a non-periodic shortest logic in an execution order in idle time in which an interrupt control logic shorter in operation period than the non-periodic shortest logic out of a signal use logic and a signal generation logic is not executed, and to execute the signal use logic while referring to a signal obtained by executing the signal generation logic, and configured to exchange execution information of the operation elements of the non-periodic shortest logic at a synchronous point per operation cycle of the interrupt control logic and to identify a preceding control unit completed with the execution of most operation elements so that each control unit preferentially executes the non-periodic shortest logic until completion of the execution of the operation elements for which the preceding control unit is completed with execution at the synchronous point.SELECTED DRAWING: Figure 5
