Commodity metering system for work vehicle and calibration method for same

A work vehicle comprising:

• a metering system that includes a metering element configured to meter a commodity through the metering system;
• a sensor system;
• and
• a control system with at least one processor, the control system configured to:
• perform a first calibration routine in which the metering element operates at a first speed, and a second calibration routine in which the metering element operates at a second speed;
• receive a first measurement and a second measurement from the sensor system, the first measurement related to a first amount of a commodity metered out by the metering element during the first calibration routine, and the second measurement related to a second amount of the commodity metered out by the metering element during the second calibration routine;
• generate first data correlating the first measurement to the first speed, and second data correlating the second measurement to the second speed;
• determine a calibration factor for operating the metering element based on the first data and the second data;
• generate a control command for the metering element according to the calibration factor;
• and
• operate the metering element according to the control command.

A method of calibrating a metering system for a work vehicle, the method comprising:

• performing, by a control system having at least one processor, multiple calibration routines in which a metering element operates at multiple speeds;
• receiving, by the control system, multiple measurements related to multiple amounts of a commodity metered out by the metering element during the multiple calibration routines;
• generating, by the control system, multiple data sets correlating the multiple measurements;
• determining, by the control system, a calibration factor for operating the metering element based on the multiple data sets;
• generating, by the control system, a control command for the metering element according to the calibration factor;
• and
• operating, by the control system, the metering element according to the control command.
