CARRIER AND BACKHOE CONTROL SYSTEM AND METHOD

摘要

A power machine (100) includes a carrier comprising a supporting frame (104), an operator compartment (112) and a joystick controller (200) disposed in the operator compartment and configured to generate movement signals in response to operator movement of the joystick controller. An attachment (132) is detachably coupled to the power machine. A carrier control unit (124) is disposed on the carrier and is configured to receive the movement signals from the joystick controller. An attachment control unit (128) is disposed on the attachment and is configured to control movement of the attachment. A network (417) is coupled to the carrier control unit and to the attachment control unit and is configured to carry instructions from the carrier control unit to the attachment control unit. A state selection input (308) is disposed in the operator compartment to select one of at least two operational states including a carrier state and an attachment state. In the carrier state, the carrier control unit is configured to control operation of the carrier in response to operator movement of the joystick controller. In the attachment state, the attachment control unit is configured to control operation of the attachment in response to operator movement of the joystick controller.
