Abstract

A method for implementing and canceling an automatic operation of a body of a machine includes receiving a selection of an automatic setting according to a first operation of a hoist mode actuator, determining an activation state of the automatic setting, causing an automatic operation of an engine of the machine to adjust an idle level of the engine and an automatic operation of a hoist system to move the body in a first direction to a first position. The method includes canceling the automatic operation of the engine and the automatic operation of the hoist system and controlling the idle level of the engine according to operations of a throttle, the hoist system to move the body according to the idle level of the engine and respective directions of the second operation the hoist mode actuator and subsequent operations of the hoist mode actuator.

First claim

We claim:

1. A method for implementing and canceling an automatic operation of a body of a machine, the method comprising:
receiving, via one or more processors, a selection of an automatic setting,
the automatic setting corresponding to a first operation of a hoist mode actuator of the machine;

determining, via the one or more processors, an activation state of the automatic setting;
causing, via the one or more processors, an automatic operation of an engine of the machine to adjust an idle level of the engine to a first idle level based on determining that the automatic setting is activated;
causing, via the one or more processors, an automatic operation of a hoist system of the body to move the body in a first direction to a first position based on a force associated with the first idle level of the engine and a direction of the first operation of the hoist mode actuator based on determining that the automatic setting is activated;
canceling, via the one or more processors, the automatic operation of the engine based on a second operation of the hoist mode actuator and controlling the idle level of the engine according to operations of a throttle of the machine; and
canceling, via the one or more processors, the automatic operation of the hoist system based on the second operation of the hoist mode actuator and controlling the hoist system to move the body according to the idle level of the engine and respective directions of the second operation the hoist mode actuator and subsequent operations of the hoist mode actuator.

2. The method of claim 1 ,
wherein the automatic operation of the engine includes:
determining, via the one or more processors, whether a current position of the body is within a predetermined range of the first position, and
causing an adjustment of the idle level of the engine from the first idle level to a second idle level.

3. The method of claim 2 ,
wherein the automatic operation of the hoist system includes moving the body based on a force associated with the second idle level of the engine for a range of movement between the current position and the first position, and
wherein the first idle level is greater than the second idle level.

4. The method of claim 1 ,
wherein the automatic operation of the hoist system includes:
detecting, via one or more sensors, a position of the body,
receiving, via the one or more processors, the position of the body from the one or more sensors, and
determining, via the one or more processors, whether the position of the body is equal to the first position and operating the hoist system to hold the body in the first position.

5. The method of claim 1 , further comprising:
detecting, via one or more sensors, a direction of movement of the body during the automatic operation of the hoist system;
determining, via the one or more processors, the direction of movement of the body does not correspond to the first operation of the hoist mode actuator; and
canceling the automatic operation of the engine and the automatic operation of the hoist system.

6. The method of claim 1 , further comprising causing a brake system of the machine to actuate brake devices to apply braking forces to respective wheels of the machine based on the first operation of the hoist mode actuator, prior to the automatic operation of the engine.

7. The method of claim 6 , further comprising:
cancelling, via the one or more processors, an automatic operation of the brake system based on an operation of a manual brake actuator and an operation of an automatic brake actuator; and
causing, via the one or more processors, the automatic operation of the engine and the automatic operation of the hoist system to continue.

8. The method of claim 7 , further comprising causing, via the one or more processors, an automatic operation of a transmission to adjust to a neutral transmission range based on the first operation of the hoist mode actuator, prior to the automatic operation of the engine.

9. The method of claim 8 , further comprising:
determining, via the one or more processors, an adjustment of the transmission based on the automatic operation of the transmission does not correspond to the first operation of the hoist mode actuator;
canceling, via the one or more processors, the automatic operation of each of the transmission, the brake system, the engine, and the hoist system; and
controlling:
the transmission to adjust a transmission range of the transmission based on operatons of a transmission range actuator,
the brake devices of the brake system based on operations of the manual brake actuator,
the idle level of the engine based on operations of the throttle of the machine, and
the hoist system to move the body based on the idle level of the engine and respective directions of operations of the hoist mode actuator.

10. A method for implementing and canceling an automatic operation of a body of a machine, the method comprising:
receiving, via one or more processors, a selection of an automatic setting,
the automatic setting corresponding to a first operation of a hoist mode actuator of the machine;

determining, via the one or more processors, an activation state of the automatic setting;
causing, via the one or more processors, an automatic operation of an engine of the machine to adjust an idle level of the engine to a first idle level based on determining the automatic setting is activated;
causing, via the one or more processors, an automatic operation of a hoist system of the body to move the body in a first direction to a first position based on a force associated with the first idle level of the engine and a direction of the first operation of the hoist mode actuator based on determining that the automatic setting is activated;
canceling, via the one or more processors, the automatic operation of the engine based on an operation of a throttle of the machine and controlling the idle level of the engine based on the operation throttle and subsequent operations of the throttle; and
causing, via the one or more processors, the hoist system to continue to a movement of the body based on the automatic operation of the hoist system.

11. The method of claim 10 ,
wherein the automatic operation of the engine includes:
determining, via the one or more processors, whether a current position of the body is within a predetermined range of the first position, and
causing an adjustment of the idle level of the engine from the first idle level to a second idle level.

12. The method of claim 11 , wherein the automatic operation of the hoist system includes moving the body based on a force associated with the second idle level of the engine for a range of movement between the current position and the first position, and
wherein the first idle level is greater than the second idle level.

13. The method of claim 10 , further comprising:
detecting, via one or more sensors, a direction of movement of the body during the automatic operation of the hoist system of the body;
determining, via the one or more processors, that the direction of movement of the body does not correspond to the first operation of the hoist mode actuator; and
canceling the automatic operation of the engine and the automatic operation of the hoist system.

14. The method of claim 10 , further comprising causing, via the one or more processors, a brake system of the machine to actuate brake devices to apply braking forces to respective wheels of the machine based on the first operation of the hoist mode actuator, prior to the automatic operation of the engine.
