Abstract

A path of travel used by an autopilot operation system for auto-guidance of a mobile machine is defined, transparently to a human operator, in response to the human operator engaging and disengaging operation of an implement coupled with the mobile machine. The auto-guidance of the mobile machine is activated, transparently to the human operator, in response to the human operator engaging the implement a second time.

Claims (54)

1. A method of transparently achieving auto-guidance of a mobile machine, the method comprising:

in response to a human operator engaging operation of an implement coupled with the mobile machine, setting a first point;

in response to the human operator disengaging operation of the implement:

setting a second point; and

defining a first path of travel between the first point and the second point used by an autopilot operation system for auto-guidance of the mobile machine transparently to the human operator;

in response to the human operator engaging operation of the implement a second time, offering, to the human operator, activation of the auto-guidance of the mobile machine transparently to the human operator, wherein activation of the auto-guidance causes the autopilot operation system to determine a second path of travel that is offset at a fixed distance substantially parallel to the first path of travel; and

in response to receiving an acceptance of the offering, activating the auto-guidance, wherein activating the auto-guidance causes movement of the mobile machine along the second path;

wherein defining of the first path of travel and activating of the auto-guidance are performed by one or more hardware processors of the autopilot operation system.

2. The method as recited by claim 1 , wherein the method further comprises:

automatically rejecting the offering if acceptance of the offering is not received with a threshold of time.

3. The method as recited by claim 1 , wherein:

engaging operation of the implement further comprises receiving a first switch input that is a first actuating of a single switch; and

disengaging operation of the implement further comprises receiving a second switch input that is a second actuating of the single switch.

4. The method as recited by claim 1 , wherein:

engaging operation of the implement further comprises receiving a first switch input when a first switch is actuated; and

disengaging operation of the implement further comprises receiving a second switch input when a second switch is actuated.

5. A non-transitory computer readable storage medium having computer readable instructions stored thereon for causing a computer system to perform a method of implementing auto-guidance of a mobile machine, the method comprising:

in response to a human operator engaging operation of an implement coupled with the mobile machine, setting a first point;

in response to the human operator disengaging operation of the implement:

setting a first point; and

defining a first path of travel between the first point and the second point used by an autopilot operation system for auto-guidance of the mobile machine transparently to the human operator;

in response to the human operator engaging operation of the implement a second time, offering activation of the auto-guidance of the mobile machine transparently to the human operator, wherein activation of the auto-guidance causes the autopilot operation system to determine a second path of travel that is offset at a fixed distance substantially parallel to the first path of travel; and

in response to receiving an acceptance of the offering, activating the auto-guidance, wherein activating the auto-guidance causes movement of the mobile machine along the second path.

6. The non-transitory computer readable storage medium as recited by claim 5 , wherein the method further comprises:

automatically rejecting the offering if acceptance of the offering is not received with a threshold of time.

7. The non-transitory computer readable storage medium as recited by claim 5 , wherein:

engaging operation of the implement further comprises receiving a first switch input when a single switch is actuated; and

disengaging operation of the implement further comprises receiving a second switch input when the single switch is actuated a second time.

8. The non-transitory computer readable storage medium as recited by claim 7 , wherein:

engaging operation of the implement further comprises receiving a first switch input when a first switch is actuated; and

disengaging operation of the implement further comprises receiving a second switch input when a second switch is actuated.

9. An autopilot operation system of a mobile machine that provides auto-guidance of the mobile machine based on an implement coupled with the mobile machine, wherein the autopilot operation system comprises:

hardware that includes a memory and a processor;

an auto-guidance system that provides the auto-guidance of the mobile machine; and

logic implemented by the hardware that causes the auto-guidance system to perform operations including:

in response to a human operator engaging operation of an implement coupled with the mobile machine, setting a first point;

in response to the human operator disengaging operation of the implement;

setting a first point; and

defining a first path of travel between the first point and the second point for auto-guidance of the mobile machine transparently to the human operator; and

in response to the human operator engaging operation of the implement a second time, offering activation of the auto-guidance of the mobile machine transparently to the human operator, wherein activation of the auto-guidance causes determining a second path of travel that is offset at a fixed distance substantially parallel to the first path of travel;

in response to receiving an acceptance of the offering, activating the auto-guidance, wherein activating the auto-guidance causes movement of the mobile machine along the second path.

10. The autopilot operation system of claim 9 , wherein the operations further include:

automatically rejecting the offer to activate the auto-guidance if acceptance of the offer is not received with a threshold of time.

11. The autopilot operation system of claim 9 , further comprising:

at least one switch that generates signals to engage and disengage the auto-guidance, wherein the switch is coupled directly with the auto-guidance system.

12. The autopilot operation system of claim 9 , further comprising:

at least one switch that generates signals to engage and disengage the auto-guidance; and

a signal-to-can-message-translation-logic, implemented by the hardware, that translates signals from the at least one switch into Controller Area Network (CAN) messages that are delivered to the auto-guidance system over a CAN bus of the mobile machine.

13. The autopilot operation system of claim 9 , further comprising:

at least one visual indicator of a status of the auto-guidance system that performs the auto-guidance of the mobile machine.

14. The autopilot operation system of claim 9 , further comprising:

at least one audio indicator of a status of the auto-guidance system that performs the auto-guidance of the mobile machine.

15. The autopilot operation system of claim 9 , further comprising:

a retroactively mounted monitor implement operation switch that provides a signal indicating a status of the operation.
