Claims24
A method for controlling movement of a work vehicle (1) that includes an equipment assembly (11) for handling objects or material, said method comprising:
- determining a state of the equipment assembly (11);
- controlling at least one operating parameter of a driveline (13) of the vehicle in dependence upon the determined equipment assembly state;
- selecting a first gear mode of at least two different predefined gear modes in dependence on the determined equipment assembly state;
- and
- controlling the at least one driveline operating parameter in dependence on the selected gear mode.
A device for moving a work vehicle (1) that includes a driveline (13) and equipment assembly (1) for handling objects or material, wherein the device comprises determination means (27,28) for determining a state of the equipment assembly (11) and a control unit (26,29) for controlling at least one operating parameter of the driveline in dependence upon the determined equipment assembly state and wherein one operating parameter is formed by lock-up in a torque converter (16) in the driveline (13).
A device for moving a work vehicle (1) that includes a driveline (13) and an equipment assembly (11) for handling objects or material, said device comprises:
- determination means (27,28) for determining a state of the equipment assembly (11) and a control unit (26,29) for controlling at least one operating parameter of the driveline depending on the determined equipment assembly state and wherein at least two different gear modes are predefined and wherein said control unit is configured to select a first gear mode depending on the determined equipment assembly state and to control said driveline operating parameter in accordance with the selected gear mode.
A method for controlling movements of a work vehicle (1) including an equipment assembly (11) for handling objects or material, said method comprising:
- determining a state of said equipment assembly (11) and controlling at least one operating parameter of a driveline (13) of the vehicle in dependence on the determined equipment assembly state and one operating parameter is formed by lock-up of a torque converter (16) in the driveline (13).
