Patent number: 7949442Abstract: A method and system for boosting a torque output of a drive train comprises an engine speed detector for detecting an engine speed of an engine having a baseline torque versus engine speed curve. A data processor determines if the detected engine speed is within a first range of engine speeds, if the detected engine speed is within the first range, the electric motor is activated to rotate substantially synchronously with the engine speed within the first range in an electric propulsion mode in accordance with a supplemental torque versus engine speed curve. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a lower engine speed point and a higher engine speed point.Type: GrantFiled: February 7, 2007Date of Patent: May 24, 2011Assignee: Deere & CompanyInventors: Alan David Sheidler, Brian Joseph Gilmore, Mark Charles DePoorter, Peter Finamore, Duane Herbert Ziegler, Joseph Albert Teijido

Patent number: 7801653Abstract: A method and system for boosting a torque output of a drive train comprises a torque sensor for detecting an engine torque of an engine having a baseline torque versus engine speed curve. A data processor determines if the detected engine torque is within a first torque range, if the detected engine torque is within the first range, the electric motor is activated to rotate substantially synchronously with a corresponding engine speed associated with the detected engine torque in accordance with a supplemental torque versus engine speed curve. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a first lower speed point and a first higher speed point.Type: GrantFiled: February 7, 2007Date of Patent: September 21, 2010Assignee: Deere & CompanyInventors: Alan David Sheidler, Brian Joseph Gilmore, Mark Charles DePoorter, Peter Finamore, Duane Herbert Ziegler, Joseph Albert Teijido

Patent number: 7446426Abstract: An engine speed detector detects an engine speed of an engine having a baseline torque versus engine speed curve. A torque sensor detects an engine torque of the engine. A data processor determines if the detected engine speed is within a first speed range and if the detected engine torque is within a first torque range. A motor controller activates an electric motor to rotate substantially synchronously with a corresponding engine speed associated with the detected engine torque in an electric propulsion mode in accordance with a supplemental torque versus engine speed curve if the detected engine speed is within the first speed range and if the detected engine torque is within the first torque range. The supplemental torque versus engine speed curve intercepts the baseline torque versus engine speed curve at a lower speed point and a higher speed point.Type: GrantFiled: August 31, 2007Date of Patent: November 4, 2008Assignee: Deere & CompanyInventors: Alan David Sheidler, Brian Joseph Gilmore, Mark Charles DePoorter, Peter Finamore, Duane Herbert Ziegler, Joseph Albert Teijido

Patent number: 6632136Abstract: A remote adjustment mechanism for the louvered cleaning elements of a combine harvester has a linearly movable output member directly fastened to the adjusting bar of each element. The actuator is driven by an electric motor. Calibration and feedback of the louver opening is provided by a pair of non-contact sensors sealed in the actuator housing. A first sensor sends a signal to a microprocessor controller when the output member is in a home position corresponding to a known louver opening. The second sensor sends a signal to the microprocessor that is responsive to movement of the output member. By tracking the movement of the output member from the home position, the current position of the output member is known from which the louver opening is determined based on the louver geometry.Type: GrantFiled: June 5, 2001Date of Patent: October 14, 2003Assignee: Deere & CompanyInventors: Mark David Anderson, Jon Leo Burns, Martin Kenneth Bush, Heather Irene Chervenka, Jeff Arthur Nelson, Jack Richard Seyller, Duane Herbert Ziegler
