Abstract
A control device for a power machine can be configured to select a power management mode from a plurality of power management modes. Each of the plurality of power management modes can define one or more operational parameters for routing of power from the electrical power source to the plurality of electrical actuators. The control device can be configured to, based on selecting the power management mode, control routing of power from the electrical power source to the plurality of electrical actuators according to the one or more operational parameters of the selected power management mode.
Claims26
A power machine comprising:
- a main frame;
- a lift arm coupled to the main frame;
- a work element supported by the lift arm;
- a plurality of electrical actuators coupled to the main frame;
- an electrical power source configured to power the plurality of electrical actuators;
- and
- a control device in communication with the plurality of electrical actuators, the control device being configured to:
- select a power management mode from a plurality of power management modes, each of the plurality of power management modes defining one or more operational parameters for routing of power from the electrical power source to the plurality of electrical actuators;
- and
- based on selecting the power management mode, control routing of power from the electrical power source to the plurality of electrical actuators according to the one or more operational parameters of the selected power management mode.
A method of operating a power machine, the method comprising:
- receiving, at an electronic control device, an input parameter corresponding to one or more of:
- an operator input that identifies a requested power management mode, or a sensed operational condition of the power machine;
- using the electronic control device, selecting a power management mode from a plurality of power management modes, based on the input parameter;
- and
- using the electronic control device, automatically controlling routing of power from an electrical power source of the power machine to one or more electrical actuators of the power machine based on the selected power management mode;
- wherein, for a given command input, different power management modes of the plurality of power management modes correspond to different respective routings of power to the one or more electrical actuators.
A method of operating a power machine, the method comprising:
- providing, with a control device, one or more electronic control signals to one or more electrical actuators to cause an orientation of an implement of the power machine to automatically fluctuate over a plurality of cycles, with each cycle of the plurality of cycles including, respectively, a first movement of the implement in a first direction away from a reference position and a second movement of the implement in a second direction away from the reference position;
- wherein providing the one or more electronic control signals is based on one or more of:
- an operator input that initiates the fluctuation over the plurality of cycles but does not directly command the first and second movements of the plurality of cycles;
- or
- detecting, with the control device, an operational condition of the power machine and determining characteristics of the plurality of cycles based on the operational condition.
