Abstract
A control system for an agricultural implement includes an electric pump fluidly coupled to a fluid cylinder and configured to control a fluid pressure within the fluid cylinder. The fluid cylinder is configured to apply a force to a ground-engaging tool of the agricultural implement. The electric pump is disposed on the agricultural implement.
Claims20
A control system for an agricultural implement, comprising:
- a first electric pump fluidly coupled to a first fluid cylinder, wherein the first electric pump is disposed on the agricultural implement, and the first fluid cylinder is configured to apply a force to a first ground-engaging tool of the agricultural implement;
- a second electric pump fluidly coupled to a second fluid cylinder, wherein the second electric pump is disposed on the agricultural implement, and the second fluid cylinder is configured to apply a force to a second ground-engaging tool of the agricultural implement;
- and
- a controller communicatively coupled to the electric pump, wherein the controller comprises a memory and a processor, and the controller is configured to:
- determine a first target fluid pressure inside the first fluid cylinder based on a first target force of the first fluid cylinder;
- determine a second target fluid pressure inside the second fluid cylinder based on a second target force of the second fluid cylinder;
- control the first electric pump to adjust a first fluid pressure inside the first fluid cylinder such that a first difference between the first fluid pressure and the first target fluid pressure is less than a first threshold;
- and
- control the second electric pump to adjust a second fluid pressure inside the second fluid cylinder such that a second difference between the second fluid pressure and the second target fluid pressure is less than a second threshold.

A control system for an agricultural implement, comprising:
- a plurality of electric pumps fluidly coupled to a plurality of fluid cylinders via a plurality of valve assemblies, wherein the plurality of electric pumps and the plurality of valve assemblies are disposed on the agricultural implement, and each fluid cylinder of the plurality of fluid cylinders is configured to apply a force to a respective ground-engaging tool of the agricultural implement;
- and
- a controller communicatively coupled to the plurality of electric pumps and the plurality of valve assemblies, wherein the controller comprises a memory and a processor, and the controller is configured to:
- determine a respective target fluid pressure for each fluid cylinder of the plurality of fluid cylinders based on a respective target force of the fluid cylinder;
- and
- control the plurality of electric pumps, the plurality of valve assemblies, or a combination thereof, such that a respective difference between the respective target fluid pressure and a respective fluid pressure in each fluid cylinder is less than a respective threshold value.
3 more elements
A method for manufacturing an agricultural implement, comprising:
- selecting a number of electric pumps based on a number of fluid cylinders on the agricultural implement;
- disposing the electric pumps on the agricultural implement;
- fluidly coupling each electric pump of the electric pumps to one or more fluid cylinders of the fluid cylinders on the agricultural implement;
- and
- communicatively coupling a controller to the electric pumps, wherein the controller is configured to:
- determine a respective target fluid pressure for each fluid cylinder of the fluid cylinders based on a respective target force of respective fluid cylinder to apply to a respective ground-engaging tool of the agricultural implement;
- and
- control each of the electric pumps independently such that a respective difference between the respective target fluid pressure and a respective fluid pressure in each fluid cylinder of the fluid cylinder is less than a respective threshold value.
