Abstract

A system comprising a work machine ECU configured to communicate with a vehicle, a vehicle ECU configured to communicate with a work machine, the vehicle ECU configured to control operation of the vehicle at in a first mode, the first mode being determined by a first signal transmitted from the work machine ECU to the vehicle ECU, the vehicle ECU configured to operate the vehicle in a second mode, the second mode being determined by a second signal transmitted from the work machine ECU to the vehicle ECU, and an actuator configured to send a command to the vehicle ECU to operate the vehicle in a third mode, the third mode being determined by a third signal transmitted from the work machine ECU to the vehicle ECU.

First claim

The invention claimed is:

1 . A system for controlling operation of a vehicle, the vehicle configured to operate in combination with a work machine and the work machine configured to perform a work function, the system comprising:
a work machine electronic control unit configured to communicate with the vehicle and to control performance of a work function of the work machine, wherein the work machine is a baler; a vehicle electronic control unit configured to communicate with the work machine and to control operation of the vehicle; wherein the vehicle electronic control unit is configured to control operation of the vehicle in a first mode, the first mode being determined by a first signal transmitted from the work machine electronic control unit to the vehicle electronic control unit, wherein the vehicle moves at a normal operating speed in the first mode, and operating the vehicle in the first mode allows the work machine to perform a primary work function that comprises collecting material along a windrow; the vehicle electronic control unit is further configured to operate the vehicle in a second mode, the second mode being determined by a second signal transmitted from the work machine electronic control unit to the vehicle electronic control unit, wherein the vehicle operates at standstill in the second mode, and operating the vehicle in the second mode allows the work machine to perform a secondary work function that comprises at least one of wrapping a bale of collected material or releasing a bale of collected material; the vehicle electronic control unit is further configured to operate the vehicle in a third mode, the third mode being determined by a third signal transmitted from the work machine electronic control unit to the vehicle electronic control unit, wherein the vehicle returns from operating at standstill in the second mode to a normal operating speed in the third mode, and operating the vehicle in the third mode allows the work machine to resume performance of the primary work function or a work function different from the secondary work function; wherein the third signal is transmitted by the work machine electronic control unit to the vehicle electronic control unit based upon a determination of an implement status information made by the work machine corresponding to completion of performance of the secondary work function by the work machine; wherein the determination of the implement status information is made by a sensor included by the work machine, and the system further comprises an actuator configured to send a command to the vehicle electronic control unit to operate the vehicle in the third mode, the command being sent when the pedal is pushed by a user to an extent in a range between 1% to 25% of acceleration or for a time within a range of 0.025s to 1s.

2 . The system according to claim 1 , wherein the first signal and second signal are sent from the work machine electronic control unit to the vehicle electronic control unit based upon further determinations made by the work machine corresponding to performance of a work function by the work machine.

3 . The system according to claim 2 , wherein the further determinations made by the work machine are made by a sensor included by the work machine.

4 . The system according to claim 3 , wherein the further determinations made by the sensor are sent to the work machine electronic control unit.

5 . The system according to claim 1 , wherein the second mode includes the vehicle moving at a speed within a range of speeds between 0.00 km/h and 0.50 km/h.

6 . The system according to claim 1 , wherein a speed of operation of the vehicle in the first mode is greater than a speed of operation of the vehicle in the second mode.

7 . The system according to claim 1 , wherein a speed of operation of the vehicle in the third mode is greater than a speed of operation of the vehicle in the second mode.

8 . The system according to claim 1 , wherein the third signal is prompted to be transmitted from the work machine electronic control unit to the vehicle electronic control unit based upon a measurement related to one or more specific feature and/or function of the vehicle.

9 . The system according to claim 8 , wherein the one or more specific feature and/or function of the vehicle are among: speed of the vehicle, oil pressure of the vehicle, hitch position of the vehicle, and power take-off rpm of the vehicle.

10 . The system of claim 8 , wherein the one or more specific feature and/or function of the vehicle is at least one of oil pressure of the vehicle or hitch position of the vehicle.

11 . A method for controlling a vehicle, the vehicle configured to operate in combination with a work machine and the work machine configured to perform a work function, the method comprising:
communicating a first signal from the work machine to the vehicle, wherein the work machine is a baler; operating the vehicle in a first mode, the first mode being determined by the first signal transmitted from the work machine to the vehicle, wherein the vehicle moves at a normal operating speed in the first mode, and operating the vehicle in the first mode allows the work machine to perform a primary work function that comprises collecting material along a windrow; communicating a second signal from the work machine to the vehicle; operating the vehicle in a second mode, the second mode being determined by the second signal transmitted from the work machine to the vehicle, wherein the vehicle operates at standstill in the second mode, and operating the vehicle in the second mode allows the work machine to perform a secondary work function that comprises at least one of wrapping a bale of collected material or releasing a bale of collected material; communicating a third signal from the work machine to the vehicle; and executing a command to operate the vehicle in a third mode, the third mode being determined by the third signal transmitted from the work machine to the vehicle, wherein the vehicle returns from operating at standstill in the second mode to a normal operating speed in the third mode, and operating the vehicle in the third mode allows the work machine to resume performance of the primary work function or a work function different from the secondary work function; wherein communicating the third signal is based upon a determination of an implement status information made by the work machine corresponding to completion of performance of the secondary work function by the work machine; wherein the determination of the implement status information is made by a sensor included by the work machine; and wherein the command is sent by using a pedal actuator when the pedal actuator is pushed by a user to an extent in a range between 1% to 25% of acceleration or for a time within a range of 0.025s to 1s.

12 . The method according to claim 11 , wherein communicating the third signal includes prompting a request to operate the vehicle in the third mode to be sent to the vehicle.

13 . The method according to claim 12 , wherein operating the vehicle in the first mode includes operating the vehicle at a speed greater than a speed of operation of the vehicle in the second mode.

14 . The method according to claim 12 , wherein operating the vehicle in the third mode includes operating the vehicle at a speed greater than a speed of operation of the vehicle in the second mode.

15 . The method of claim 12 , wherein communicating the third signal from the work machine electronic control unit to the vehicle electronic control unit is prompted based
