US 10,309,528 B2 · Vehicular hydraulic control device and vehicular hydraulic control method

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 (PTh) determined in accordance with the demanded drive force from the driver; and a pressure regulation target value of a line pressure regulation valve (101) is set to a value that is higher than or equal to the target hydraulic pressure (PTh). 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 (PTh).

Dependent claims

A vehicular hydraulic control device comprising:

a hydraulic pressure source;
a line pressure regulation valve configured to regulate a discharge pressure outputted from the hydraulic pressure source;
and
a hydraulic pressure controller configured to perform a first operation in response to an indication of driver's request for driving force when the hydraulic pressure source is at rest, wherein the first operation includes:
starting to control the hydraulic pressure source in a manner to conform the discharge pressure to a target hydraulic pressure, wherein the target hydraulic pressure is determined in accordance with a driver-requested driving force;
and
setting a pressure regulation target value of the line pressure regulation valve greater than or equal to the target hydraulic pressure.
