Embodiment Construction

[0019]The following describes one or more example embodiments of the disclosed system and method, as shown in the accompanying figures of the drawings described briefly above. Various modifications to the example embodiments may be contemplated by one of skill in the art.

[0020]As used herein, unless otherwise limited or modified, lists with elements that are separated by conjunctive terms (e.g., “and”) and that are also preceded by the phrase “one or more of” or “at least one of” indicate configurations or arrangements that potentially include individual elements of the list, or any combination thereof. For example, “at least one of A, B, and C” or “one or more of A, B, and C” indicates the possibilities of only A, only B, only C, or any combination of two or more of A, B, and C (e.g., A and B; B and C; A and C; or A, B, and C).

[0021]As used herein, the term module refers to any hardware, software, firmware, electronic control component, processing logic, and / or processor device, in...

Abstract

A mechanical creeper mode selection system for a transmission of a work vehicle is provided, in which the transmission includes one or more range modes having one or more range mode shift mechanisms each driven by an electrohydraulic circuit. The system includes a creeper mode selection lever movable by an operator to select a creeper gear range. The system also includes a sensor that observes a position of the creeper mode selection lever and generates sensor signals based thereon. The system includes a controller that processes the sensor data to determine a movement of the creeper mode selection lever and outputs one or more control signals to the electrohydraulic circuit to position the one or more range mode shift mechanisms in a range neutral mode based on the movement of the creeper mode selection lever.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S)[0001]Not applicable.STATEMENT OF FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.FIELD OF THE DISCLOSURE[0003]This disclosure relates to a work vehicle and the selection of a creeper mode of a transmission of the work vehicle.BACKGROUND OF THE DISCLOSURE[0004]In the agricultural industry, various work vehicle, such as tractors, can be used with various work implements to cultivate a field. Generally, the work vehicle comprises an engine coupled to a transmission, which transfers power generated by the engine to one or more driven wheels of the work vehicle, thereby controlling a speed of the work vehicle. In certain instances, however, a low gear range associated with the transmission may not be able to provide the work vehicle with a desired low speed. For example, during a tillage or planting operation, it may be desirable to operate the tractor in an ultra low speed, such that the tractor moves slowly or “creeps” along the...
