APPARATUS AND METHOD FOR INCHING USING A CONTINUOUSLY VARIABLE TRANSMISSION
First Claim
1. An agricultural vehicle, comprising:
- an engine;
a continuously variable transmission operably connected to the engine;
a processor operably connected to the continuously variable transmission;
an inching controller operably connected to the processor; and
a speed controller operably connected to the processor;
wherein the speed controller is configured to send a first signal to the processor, and the processor is configured to control the transmission to operate the vehicle at a first speed based on the first signal,wherein the inching controller is configured to send a second signal to the processor, and the processor is configured to control the transmission to move the agricultural vehicle in a forward or reverse direction, depending on the second signal, andwherein the processor is configured such that if the first speed based on the first signal is zero, the second signal will trigger the processor to control the transmission to move the agricultural vehicle in the forward or reverse direction a predetermined first distance.

Abstract
An agricultural vehicle and method of operating the same, where the agricultural vehicle has an engine, a continuously variable transmission, a processor, an inching controller, and a speed controller. The speed controller sends a first signal to the processor, and the processor controls the transmission to operate the vehicle at a first speed based on the first signal. The inching controller sends a second signal to the processor, and the processor controls the transmission to move the agricultural vehicle in a forward or reverse direction, depending on the second signal. If the first speed based on the first signal is zero, the second signal triggers the processor to control the transmission to move the agricultural vehicle in the forward or reverse direction a predetermined first distance. The control of the vehicle to be at zero speed or to be in a particular position is effectuated by a position control mechanism.

23. An agricultural vehicle, comprising:
-
an engine; a continuously variable transmission operably connected to the engine; a processor operably connected to the continuously variable transmission; and a device for measuring the position of the vehicle operably connected to the processor; wherein the processor is configured to; determine a position setpoint; determine a current position of the vehicle based on information received from the device for measuring the position of the vehicle; compare the position setpoint and the current position of the vehicle to obtain a position setpoint error indicative of the difference between the position setpoint and the current position of the vehicle; and control the transmission to move the vehicle from the current position towards the position setpoint to reduce the position setpoint error. - View Dependent Claims (24, 25, 26, 27, 28)
