System for automated excavation control based on productivity
First Claim
1. A control system for a mobile excavation machine, comprising:
- a ground engaging work tool;
a sensor configured to sense a parameter indicative of a current travel speed of the mobile excavation machine and to generate a speed signal in response thereto; and
a controller in communication with the ground engaging work tool and the sensor, the controller being configured to;
receive an operator input indicative of a desired autonomous dig function;
increase the travel speed to a maximum amount and engage the ground engaging tool with a work surface in response to the operator input;
receive the speed signal from the sensor;
determine an amount of material currently being moved by the work tool;
calculate a current productivity value associated with removal of the material based on the speed signal and the determined amount of material currently being moved; and
control the ground engaging work tool to vary the amount of material currently being moved in response to the current productivity value.

Abstract
A control system for a mobile excavation machine is disclosed. The control system may have a ground engaging work tool, a sensor, and a controller. The sensor may be configured to sense a parameter indicative of a current travel speed of the mobile excavation machine and generate a speed signal in response thereto. The controller may be in communication with the ground engaging work tool and the sensor, and configured to receive the signal. The controller may also be configured to determine an amount of material currently being moved by the work tool and calculate a current productivity value associated with removal of the material based on the speed signal and the determined amount of material currently being moved. The controller may be further configured to control the ground engaging work tool to vary the amount of material currently being moved in response to the current productivity value.

17. A mobile excavation machine, comprising:
-
a power source configured to generate a power output; a traction device configured to receive the power output and propel the mobile excavation machine; a ground engaging work tool driven by the power source to move into and out of a work surface; a sensor configured to sense a parameter indicative of a travel speed of the mobile excavation machine and to generate a signal in response thereto; a load sensor configured to sense a parameter indicative of a current amount of material being excavated; and a controller in communication with the ground engaging work tool, the speed sensor, and the load sensor, the controller being configured to; receive an operator input indicative of a desired autonomous dig function; increase the travel speed to a maximum amount and engage the ground engaging tool with a work surface in response to the operator input; calculate a current productivity value associated with removal of the material based on the speed signal and the load signal; and control the ground engaging work tool to vary the amount of material currently being moved in response to the current productivity value. - View Dependent Claims (18, 20)
