POWER SUPPLY OF CONTROLLER CONTROL PART

摘要

PURPOSE:To avoid waste of power at a main power supply part by a method wherein a DC-DC regulator for obtaining controlling power required at a controller control part by using driving power to be supplied to an engine control part from a main power supply part as an input, is established to the controller part. CONSTITUTION:An engine control part 1 and a controller control part 13 are independently constructed. An outer interface connecter 13-1 to be connected to an outer host machine 3 is provided at one end of the controller control part 13. An IC card connector 13-2 to be connected to a control IC of the engine control part 11 and an engine interface connector 13-3 for supplying driving power from a main power supply part 10 to a DC-DC regulator 14 are provided at the other end thereof, and the controller control part can be simply exchanged. The controller control part 13 forms controlling power to be used in the controller control part 13 with the DC.-DC regulator 14 by using driving power to be obtained via the engine connector 13-3 of the engine control part 11 as an input.
