Title:
HYDRAULIC CONTROL DEVICE AND HYDRAULIC CONTROL METHOD FOR AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2020/054263
Kind Code:
A1
Abstract:
The present invention comprises an engine (1) and an assist motor (10) as power sources. An engine control module (9) comprises a torque assist control unit (9a) that controls the assist motor via a plurality of types of switching patterns having different torque assist levels. A CVT control unit (8) comprises a torque assist coordination control unit (8a) that, when a torque assist request is inputted from the torque assist control unit (9a), performs control that increases commanded hydraulic pressure so as to increase the hydraulic pressure of a hydraulically operated member. When performing control that increases the commanded hydraulic pressure, the torque assist coordination control unit (8a) sets a uniform commanded hydraulic pressure level regardless of the type of switching pattern.
