Abstract
The present invention is configured such that: in a stopped state of an electric oil pump (M/O/P), control of the electric oil pump (M/O/P) is started such that, when a driver has the intention of demanding drive force, a discharge pressure takes on a target hydraulic pressure (P) determined in accordance with the demanded drive force from the driver; and a pressure regulation target value of a line pressure regulation valve () is set to a value that is higher than or equal to the target hydraulic pressure (P). Thus, it is possible to provide a vehicular hydraulic control device capable of suppressing hunting in line pressure (PL) when the line pressure (PL) is regulated so as to take on the target hydraulic pressure (P).
