MACHINE CONTROL SYSTEM AND METHOD
First Claim
1. A control system for a machine, comprising:
- a processor configured to communicate with;
a power source, anda transmission assembly;
the processor being configured to;
determine whether the power source is in a potential stall condition based at least in part on an actual speed of the power source and a requested speed of the power source, andif the power source is in the potential stall condition, request that fuel be supplied to the power source although the fuel is not currently required by the power source, in anticipation of an increase in load on the machine.

Abstract
A control system for a machine may include a processor configured to communicate with a power source. The processor may also be configured to communicate with a transmission assembly. The processor may be configured to determine whether the power source is in a potential stall condition based at least in part on an actual speed of the power source and a requested speed of the power source. If the power source is in the potential stall condition, the processor may be configured to request that fuel be supplied to the power source although the fuel is not currently required by the power source, in anticipation of an increase in load on the machine.

1. A control system for a machine, comprising:
-
a processor configured to communicate with; a power source, and a transmission assembly; the processor being configured to; determine whether the power source is in a potential stall condition based at least in part on an actual speed of the power source and a requested speed of the power source, and if the power source is in the potential stall condition, request that fuel be supplied to the power source although the fuel is not currently required by the power source, in anticipation of an increase in load on the machine. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A method for controlling a machine including a power source and a transmission assembly, the method comprising:
-
determining whether the power source is in a potential stall condition based on an actual speed of the power source and a requested speed of the power source; if the power source is in a potential stall condition, determining whether a requested transmission assembly torque is increasing; and informing the power source that a load is coming based at least in part on the requested transmission assembly torque to prepare the power source for the oncoming load, in anticipation of the oncoming load. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A machine comprising:
-
a power source; a governor configured to control power source fueling based on an actual speed of the power source and a requested speed of the power source; a transmission assembly operatively coupled to the power source; and a control system operatively coupled to the power source and the transmission assembly, the control system being configured to; determine whether the power source is in a potential stall condition due to a response of the governor to a difference between the actual power source speed and the requested power source speed, and request that fuel be supplied to the power source to remedy the potential stall condition in anticipation of an increase in load on the machine. - View Dependent Claims (16, 17, 18, 19, 20)
