US Patent:

8585543, Nov 19, 2013

Filed:

Nov 1, 2012

Appl. No.:

13/666250

Inventors:

Adam Nackers - East Peoria IL, US
Steven Ott - Washington IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

F16H 61/662

US Classification:

477 43

Abstract:

A system and method of controlling the speed of a machine having a continuously variable transmission (CVT) operatively coupled to a power source. A plurality of selectable virtual gear ratios can be associated with the CVT. The machine may include an operator input device that may generate a operator input signal indicative of a desired adjustment in the ground speed. The operator input signal may be converted to a CVT speed command and to a power source speed command that are communicated to the CVT and the power source, respectively. The CVT adjusts the machine speed in accordance with the CVT speed command, while the power source adjusts its speed in accordance with the power source speed command, so that operation of the power source is substantially independent of operator of the CVT.

International Classification:

E02F 9/20
E02F 9/26
G05D 1/00
H04W 12/06

Abstract:

In one aspect, a method for shared access of a machine for operator training, the machine including a traction device and an implement, includes receiving an authorization from an access device to share access to the machine, and entering a shared control state based on at least the authorization received from the access device. The method also includes receiving commands from a remote operation device during the shared control state and operating at least one of the traction device or the implement of the machine based on at least the commands from the remote operation device while an operator is present in the machine.

International Classification:

B60W 10/101

US Classification:

701 54, 477 37, 477 43

Abstract:

A machine may include a continuously variable transmission (CVT) operatively coupled to a power source. A virtual gear ratio may be selected from a plurality of virtual gear ratios associated with the CVT. A power source speed may be locked between a minimum power source limit and a maximum power source limit that are associated with the selected virtual gear ratio. If the virtual gear ratio is changed, a controller including one or more control maps may compare the power source speed as locked to the minimum power source limit and the maximum power source limit as they relate to the newly selected virtual gear ratio. If power source speed is outside the minimum or maximum power source limits, the method may limit the power source speed. In some embodiments, the minimum and/or maximum power source limits may vary with respect to the plurality of virtual gear ratios.
