PROBLEM TO BE SOLVED: To provide an engine speed control device capable of suitably suppressing a revolution fluctuation of an engine in a transition period of switching a compressor to be driven/stopped without causing over-response to feedback control of an engine speed during idling operation.SOLUTION: An electronic control unit 25 performs ISC feedback on the basis of pre-FB AC control torque as a calculation value for the load torque of a compressor 24, while performing feedback correction of engine torque equivalent to AC load torque in a transition period of switching the compressor 24 to be driven/stopped, on the basis of a future AC control torque as a value for feedback corrected pre-FB AC control torque according to a deviation of the engine speed from an ISC target speed, and latest AC control torque. |
