Method And System For Controlling A Driving Direction Of An Electric Drive Machine

View page
US Patent:
20110022276, Jan 27, 2011
Filed:
Jul 27, 2009
Appl. No.:
12/509836
Inventors:
Srikar Thaduvayi - Peoria IL, US
William J. Tate - Dunlap IL, US
Michael D. Staub - Metamora IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
G06F 19/00
B60T 8/172
US Classification:
701 48, 701 36
Abstract:
The disclosure describes, in one aspect, a method for changing a direction of a machine that is moving in a first direction. The method includes the step of receiving a signal indicative of an intention to change the direction of the machine to a second direction. The method also includes the step of determining whether a signal indicative of a speed of the machine is greater than a threshold based at least in part on an electric motor parameter. Finally, the method includes the step of applying a braking torque to at least one travel mechanism of the machine in response to a signal indicative of an accelerator pedal position until the speed reaches the threshold.

Systems And Methods For Engine Load Management For Electric Drive Vehicles

US Patent:
20130006456, Jan 3, 2013
Filed:
Jun 29, 2011
Appl. No.:
13/171506
Inventors:
Srikar THADUVAYI - Dunlap IL, US
Phillip James Houtz - West Lafayette IN, US
Jeffrey Alan Brand - Chillicothe IL, US
Alexander Cameron Crosman - Dunlap IL, US
International Classification:
B60W 20/00
US Classification:
701 22, 180 65245, 180 65265, 903902
Abstract:
A method for load management for an electric drive machine comprises receiving a fuel signal indicative of a volume of fuel provided to an engine associated with the electric drive machine, receiving an engine speed signal indicative of a rotational speed of an output shaft of the engine, and receiving a boost pressure signal indicative of a pressure of air at an intake manifold of the engine. The method further includes determining a torque adjustment factor based on the fuel signal and the boost pressure signal, and determining a torque capability of the engine based on the fuel signal and the engine speed signal An engine torque limit is determined based on the torque capability and the torque adjustment factor A first motor torque command signal is determined for a first electric drive motor of the electric drive machine based at least in part on the engine torque limit.

Controlling Retarding Torque In An Electric Drive System

US Patent:
20130162182, Jun 27, 2013
Filed:
Dec 21, 2012
Appl. No.:
13/723288
Inventors:
Brett M. Nee - Metamora IL, US
Joshua M. Williams - Peoria IL, US
Benjamin P. Gottemoller - Princeville IL, US
Srikar Thaduvayi - Peoria IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
H02P 15/00
US Classification:
318380
Abstract:
The disclosure describes, in one aspect, a system for a machine having an electric drive configuration. The system includes an electric motor associated with at least one wheel and adapted to provide retarding torque to the wheel, and a controller configured to determine a power measurement of a retarding grid and control the retarding torque to the at least one wheel during retarding as a function of the power measurement.

Vector Currents Controller For Salient Pole Synchronous Machine

View page
US Patent:
20160276962, Sep 22, 2016
Filed:
Mar 18, 2015
Appl. No.:
14/661791
Inventors:
- Peoria IL, US
Ernesto Inoa - Dunlap IL, US
Baojun Si - Dunlap IL, US
Srikar Thaduvayi - Peoria IL, US
William J. Tate - Dunlap IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
H02P 6/00
H02P 6/04
H02P 6/08
Abstract:
A control system for an alternating current (AC) machine having a rotor and a stator is disclosed. The control system may include a direct current (DC) link providing a variable DC link voltage; an inverter module operatively coupled between the DC link and the AC machine, and a controller in communication with the inverter module. The inverter module may include a plurality of gates in selective communication with each phase of the stator. The controller may be configured to receive a signal indicative of the variable DC link voltage, receive a signal indicative of a rotational speed of the rotor, receive a torque command, and generate a direct-axis current command and a quadrature-axis current command using the variable DC link voltage, the rotational speed, and the torque command as inputs into a three-dimensional lookup table preprogrammed into a memory associated with the controller.

US Patent:
20150134163, May 14, 2015
Filed:
Nov 13, 2013
Appl. No.:
14/078672
Inventors:
- Peoria IL, US
Srikar Thaduvayi - Peoria IL, US
Karl Schneider - Decatur IL, US
Michael A. McKeever - Canton IL, US
Joseph E. Roth - West Lafayette IN, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60W 20/00
B60K 11/06
H02P 9/00
US Classification:
701 22
Abstract:
An electric drive control system for a machine is provided. The electric drive control system includes a sensor and a drivetrain control module operatively coupled to the sensor. The sensor is configured to determine one or more operational parameters associated with the machine. The drivetrain control module is further operatively coupled to a power source controller associated with a power source and a generator controller associated with a generator. The drivetrain control module is configured to determine a desired operating mode of the machine and selectively regulate one or parameters associated with the power source based on a predefined dataset corresponding to the desired operating mode of the machine. The drivetrain control module is further configured to selectively adjust an amount of power produced by the generator based on the predefined dataset corresponding to the desired operating mode of the machine.
