  • Systems and methods for controlling engine speed
    Patent number: 12162362
    Abstract: A power machine can include an engine control module configured to determine a target operational speed of the power machine and control the engine based on the target operational speed. A drive controller can be configured to control operation of a hydraulic drive pump or other work element to decrease engine speed toward a target stabilization speed that is lower than the target operational speed.

  • MODULATING OPERATOR INPUT FOR WORK ELEMENT ACTUATOR OPERATION
    Publication number: 20220374011
    Abstract: A control system for controlling movement of a work element of a power machine can include a control device, and an operator input device in communication with the control device. The control device can be configured to receive, from the operator input device, a signal for controlling an actuator of the work element. The signal can be filtered, using a digital notch filter, to generate a filtered signal, and an actuator of the work element can be controlled based on the filtered signal.
