Abstract
In a hydraulic control device switchable between a first state in which a first oil is supplied from a first pump to a hydraulic operation part via a bypass valve and a second state in which the first oil supplied from the first pump is pressurized by using the second pump and the pressurized first oil is supplied, as a second oil, to the hydraulic operation part, when the second pump is stopped in the second state, control that gradually decreases a target rotation speed of the second pump is performed, and rates at which the target rotation speed of the second pump decreases differ in a case where the second pump is stopped in an operation-allowed region and in a case where the second pump is stopped when the second pump is determined as in an operation-disallowed region.
