Patent number: 11577605Abstract: An all-wheel-drive electric vehicle includes one or more front electric motors, one or more rear electric motors, an accelerator sensor, a vehicle speed sensor, and a control unit. The one or more front electric motors are configured to directly drive front wheels. The one or more rear electric motors are configured to directly drive rear wheels. The accelerator sensor is configured to determine an operation amount of an accelerator. The vehicle speed sensor is configured to determine vehicle speed. The control unit is configured to control drive of the one or more front and rear electric motors based on the operation amount of the accelerator and the vehicle speed.Type: GrantFiled: June 22, 2022Date of Patent: February 14, 2023Assignee: SUBARU CORPORATIONInventors: Hiroaki Shiokawa, Chihiro Oguro

Patent number: 10724630Abstract: In a control apparatus for an automatic transmission, in a drive train, a driving source and the automatic transmission having a plurality of gear-shift stages including the gear-shift stages at each of which a one way clutch is engaged during a drive are equipped, a gear-shift line correction by such coast correction lines as to provide such gear-shift line shapes projecting toward a lower vehicle speed side in a small accelerator opening area is added to up-shift lines of the gear-shift stages at each of which the one way clutch participates from among the gear-shift lines after the correction by vehicle speed correction lines.Type: GrantFiled: February 9, 2016Date of Patent: July 28, 2020Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Shunsuke Ogasawara, Hiroaki Shiokawa, Yuichiro Matsunaga

Patent number: 10641386Abstract: In an automatic transmission control device of the invention configured to start an increase in engagement pressure of a start-up engagement element, when a determination threshold value for determining that a turbine rotational speed has reduced is reached or exceeded, the determination threshold value when a selection operation from a non-traveling range to a traveling range is made before a prescribed period of time from starting of an engine has elapsed, is increased and set greater than the determination threshold value when the selection operation is made after the prescribed period of time has elapsed. Accordingly, a reduction in the turbine rotational speed can be accurately determined, and thus it is possible to suppress torque fluctuations, occurring owing to engagement of a second brake, which is the start-up engagement element.Type: GrantFiled: October 21, 2016Date of Patent: May 5, 2020Assignee: JATCO LTDInventors: Ryosuke Fujii, Hiroaki Shiokawa
