PURPOSE:To control end update a control subject device in a short application time of a CPU by controlling the control subject device in a short control period with the large load of the device and in a long control period with the small load of the device respectively. CONSTITUTION:A load measuring device 12 measures the load state value of a control subject device 10, and a control period deciding device 14 decides the small control period value with a large load state and the large control period value with a small load state respectively in accordance with the load state value measured by the device 12. Then a controller 13 controls the device 10 based on the control period value decided by the device 14. Therefore it is not so much required to control the device 10 with a sparse load of the device 10. Thus the controller 13 controls the device 10 in a long period. |
