EXCAVATION SYSTEM PROVIDING AUTOMATED STALL CORRECTION

摘要

An excavation system is disclosed for a machine having a work tool. The excavation system may have first and second actuators configured to move the work tool in first and second directions, at least a first valve configured to regulate fluid flow through the first actuator, and at least a second valve configured to regulate fluid flow through the second actuator. The excavation system may also have at least one sensor to generate a first signal indicative of a performance of the first actuator, and a controller in communication with the at least a first valve, the at least a second valve, and the at least one sensor. The controller may be configured to make a first determination that the first actuator is experiencing a stall condition based on the first signal, and to selectively command neutralization of the powertrain and movement of the second actuator based on the first determination.

1. An excavation system for a machine having a work tool, a traction device, and a powertrain configured to power the work tool and the traction device, the excavation system comprising:
a first actuator configured to move the work tool in a first direction; at least a first valve configured to regulate fluid flow through the first actuator; at least one sensor configured to generate a first signal indicative of a performance of the first actuator; a second actuator configured to move the work tool in a second direction; at least a second valve configured to regulate fluid flow through the second actuator; and a controller in communication with the at least a first valve, the at least one sensor, the at least a second valve, and the powertrain, the controller being configured to:
make a first determination that the first actuator is experiencing a stall condition based on the first signal; andselectively command neutralization of the powertrain and movement of the second actuator based on the first determination.
