Patent number: 8690720Abstract: A hydraulic control device for an automatic transmission capable of adjusting the amount of lubricating oil in accordance with a load on a torque converter is provided. A main regulator valve regulates hydraulic oil from an oil pressure source on the basis of a stator reaction force of the torque converter to generate a line pressure for operating engagement of a frictional engagement element. A line pressure switching section switches the line pressure to a low line pressure in a region in which a higher line pressure is not required in response to a driving state of a vehicle, and switches the line pressure to a high line pressure when a target value of an engagement hydraulic oil pressure exceeds a predetermined pressure. A lubricating regulator valve is provided in a lubricating oil passage connected from the main regulator valve to regulate a hydraulic pressure in the lubricating oil passage to a given pressure in response to a driving state of the vehicle.Type: GrantFiled: June 18, 2010Date of Patent: April 8, 2014Assignee: Honda Motor Co., Ltd.Inventors: Hiroshi Takei, Yoshimichi Tsubata, Koichi Fushimi, Kazuaki Watanabe
