Patent number: 10040456Abstract: A multi-speed automatic transmission having a control circuit for managing a hill climb event is provided. The control circuit may detect the hill climb event, such as by identifying when an upshift from a climb gear to an upshift gear would cause deceleration on a hill. The control circuit may also respond to the hill climb event based on desired performance characteristics, including fuel economy, speed, acceleration, and other performance characteristics. In one embodiment, the control circuit responds to the hill climb event by cycling the multi-speed automatic transmission between the climb gear and the upshift gear.Type: GrantFiled: November 18, 2016Date of Patent: August 7, 2018Assignee: Allison Transmission, Inc.Inventors: Stephen T. West, John A. Byerly, Jared S. Shattuck

Patent number: 9964162Abstract: A device, system, and method for controlling transmission torque to provide hill ascent and/or descent assistance to a vehicle includes applying a clutch hold pressure to one or more clutches of a transmission to lock an output shaft of the transmission to resist roll-back of the vehicle. The clutch hold pressure is applied based on one or more of a transmission output speed signal, an engine throttle signal, and a vehicle brake signal.Type: GrantFiled: March 15, 2013Date of Patent: May 8, 2018Assignee: Allison Transmission, Inc.Inventors: Jared S. Shattuck, Jeffrey E. Shultz, Peter G. York

Patent number: 9383010Abstract: The present invention provides a method of selecting and implementing a shift schedule for a transmission in a vehicle that includes an output speed sensor and a controller. The method includes measuring output speed with the output speed sensor and comparing the measured output speed to an output speed threshold. The controller receives throttle percentage and compares the throttle percentage to a throttle threshold. The method also includes calculating output acceleration and transmission gear ratio with the controller. The shift schedule is selected based on the measured output speed, calculated output acceleration, calculated transmission gear ratio, and throttle percentage.Type: GrantFiled: January 8, 2014Date of Patent: July 5, 2016Assignee: Allison Transmission, Inc.Inventors: Jeffrey E. Shultz, Jared S. Shattuck

Patent number: 9365201Abstract: A device, system, and method for controlling transmission torque to provide hill ascent and/or descent assistance to a vehicle includes applying a clutch hold pressure to one or more clutches of a transmission to lock an output shaft of the transmission to resist roll-back of the vehicle. The clutch hold pressure is determined as a function of the tractive effort of the vehicle and is applied based on one or more of a transmission output speed signal, an engine throttle signal, and a vehicle brake signal.Type: GrantFiled: March 15, 2013Date of Patent: June 14, 2016Assignee: Allison Transmission, Inc.Inventors: Jared S.

Patent number: 8151778Abstract: An intake manifold is disclosed. The intake manifold includes a first chamber in fluid communication with a PCV line and disposed generally upstream of a second chamber. The chambers are designed to provide a long flow path for the moisture laden PCV gas and to help reduce the introduction of moisture or fluids into the second chamber. This helps to prevent the ingestion of moisture or fluids by the combustion chambers of engine. An optional fluid blocker can also be used to trap fluids and help prevent those fluids from entering a cylinder port.Type: GrantFiled: October 28, 2010Date of Patent: April 10, 2012Assignee: Honda Motor Co., Ltd.Inventors: Joel K. Lewis, Marcos J. DeLeon, Jared S. Shattuck, Yuichiro Tanabe, Takeshi Aoki
