Control system and method for capturing partial bucket loads in automated loading cycle
First Claim
1. A method of loading material with a machine comprising the steps of:
- moving a bucket of the machine into a pile of material;
capturing a full bucket load of the material at least in part by tilting the bucket in the pile, and removing the fully loaded bucket from the pile at a first tilt angle;
determining on a processor a bucket tilt parameter for the bucket which corresponds with a predetermined partial bucket load;
moving the bucket into the pile again; and
capturing a partial bucket load at least in part by controllably tilting the bucket in the pile according to the determined bucket tilt parameter, and removing the partially loaded bucket from the pile at a partial tilt angle less than the first tilt angle.

Abstract
An automated bucket loading control method includes determining a bucket tilt parameter for a bucket of the machine which corresponds with a partial bucket load, and capturing a partial bucket load by controllably tilting the bucket in a pile of material according to the determined bucket tilt parameter. A control system includes a sensor configured to monitor a bucket tilt parameter and output a bucket tilt signal, and further includes an electronic payload controller coupled with the sensor which is configured to output bucket tilting control commands. The electronic payload controller is further configured to determine a value for the bucket tilt parameter that corresponds with a target partial bucket load and output corresponding bucket tilting control commands during moving a bucket of the machine in a material pile to capture a partial bucket load.
