To provide an ISC control device and a vehicular ejector system capable of suitably restraining a variation in an idle speed of an internal combustion engine, even if an ejector is made to function or the function is stopped.
An ECU 40A is used together with the ejector system 100A comprising an ejector 30 for controlling the idle speed of the internal combustion engine 50 by controlling an electric throttle 13 for adjusting an intake flow rate supplied to the internal combustion engine 50 and generating negative pressure larger than negative pressure tried to be take out of an intake manifold 14, VSV1A for making the ejector 30 function or stopping the function, and the ECU 40A controlling the VSV1A; and has an ISC control quantity correcting means for correcting an ISC control quantity for controlling the electric throttle 13 in ISC by an ejector correction quantity corresponding to the intake flow rate of increasing-decreasing in response to an operation state of the VSV1A.
