摘要：
A control apparatus for a negative pressure generating apparatus includes an ejector that generates a negative pressure whose magnitude is larger than that of a negative pressure to be taken from an intake passage in an intake system for an internal combustion engine provided in a vehicle; a state change device that makes the ejector function or stop functioning; and a predetermined value change device that changes a predetermined value according to an operating state of the vehicle, when the state change device makes the ejector function based on a result of a comparison between the negative pressure to be taken from the intake passage and the predetermined value.
