Abstract
A yaw rate is sensed on a towing vehicle that is towing an air seeder. The sensed yaw rate is used to predict a future yaw rate on a planting implement of the air seeder. An application rate of material is varied across the application implement based upon the predicted yaw rate across the implement.
Claims20
An agricultural system, comprising:
- a towing vehicle;
- an agricultural machine, coupled to the towing vehicle, including an application tool that applies material to a field at work points distributed along a transverse axis of the application tool;
- an instantaneous yaw rate detector detecting an instantaneous yaw rate of the towing vehicle;
- a tool yaw rate prediction system predicting, based on the instantaneous yaw rate detected on the towing vehicle, a plurality of different yaw rate values, each predicted yaw rate value of the plurality of different predicted yaw rate values corresponding to each work point of a set of the work points distributed along the transverse axis of the application tool;
- and
- a meter controller generating a control signal to control a meter that controls a rate at which the material is provided to the work points based on the plurality of different predicted yaw rate values.

A computer system, comprising:
- at least one processor;
- and
- a data store storing computer executable instructions which, when executed by the at least one processor, causes the at least one processor to perform steps to control an agricultural machine, comprising:
- receiving an instantaneous yaw rate of the towing vehicle, the towing vehicle towing an application tool that applies material to a field at work points distributed along a transverse axis of the application tool;
- predicting, based on the instantaneous yaw rate detected on the towing vehicle, a plurality of different yaw rate values, each predicted yaw rate value of the plurality of different predicted yaw rate values corresponding to each work point of a set of the work points distributed along the transverse axis of the application tool;
- and
- generating a control signal to control a meter that controls a rate at which the material is provided to the work points based on the plurality of different predicted yaw rate values.
