Abstract
Automated operation methods and systems are provided for power machines. One system includes an electronic processor configured to determine, based on the operational data, a current lift position associated with a power machine. The electronic processor may also be configured to determine, based on the current lift position, a target tilt position associated with a work element of the power machine and control an electric tilt actuator based on the target tilt position.
Claims19
A system for controlling an electric power machine, the system comprising:
- one or more electronic processors in electrical communication with an electric tilt actuator and an electric lift actuator that manipulate a workgroup of the electric power machine and configured to:
- receive operational data for the electric power machine;
- determine, based on the operational data, a current lift position of the electric lift actuator;
- determine, based on the current lift position, a target tilt position for the electric tilt actuator;
- and
- control the electric tilt actuator based on the target tilt position.
A method for controlling an electric power machine, the method comprising, with one or more electronic processors:
- receiving operational data for the electric power machine;
- determining, based on the operational data, a current lift position of a lift arm assembly of the electric power machine;
- determining, based on the current lift position, a target tilt position of a tilt assembly of the electric power machine, the tilt assembly including an electric tilt actuator that is configured to adjust a tilt position of the tilt assembly;
- and
- controlling the electric tilt actuator, based on the target tilt position, to adjust a current tilt position of the tilt assembly.
An electric power machine, the electric power machine comprising:
- a power machine frame;
- a plurality of electric actuators supported by the power machine frame, wherein the plurality of electric actuators includes an electric lift actuator and an electric tilt actuator;
- a lift arm structure that includes:
- a lift arm coupled to the power machine frame and configured to be moved relative to the power machine frame by the electric lift actuator;
- and
- a work element supported by the lift arm and configured to be moved relative to the lift arm by the electric tilt actuator;
- an electric power source configured to power the plurality of electric actuators;
- and
- one or more electronic processors in communication with the plurality of electric actuators, the one or more electronic processors configured to, during operation of the electric power machine in a work element leveling mode:
- monitor a current lift position of the electric lift actuator;
- determine, based on the current lift position, a target tilt position for the electric tilt actuator;
- control the electric tilt actuator based on the target tilt position;
- and
- responsive to a change in the current lift position:
- determine, based on the change in the current lift position, an adjusted target tilt position for the electric tilt actuator;
- and
- control the electric tilt actuator based on the adjusted target tilt position.
