とを特徴とする補機類の駆動制御装置。 The auxiliary air flow rate is controlled by controlling the opening degree of an idle control valve installed in a passage that bypasses the intake throttle valve under predetermined idle operating conditions, and the engine rotation speed detected by the rotation speed detection means is controlled. The engine is equipped with an idle rotation speed feedback control means for controlling the engine speed so that the engine speed approaches the target rotation speed, and the O
In a drive control device for auxiliary machinery, the target rotation speed is set to a higher value during N control than when OFF,
A rate-of-change detection means detects a rate of change in the engine speed, and after the auxiliary equipment ON/OFF switching signal is output, the auxiliary equipment is detected after the detected rate of change in the engine speed exceeds a predetermined value. 1. A drive control device for auxiliary machinery, comprising a switching delay means for switching ON and OFF of the auxiliary machinery.
