Abstract
A method for controlling a power source (1, 10) of a forestry machine, wherein the power source utilizes directly or indirectly one or more work devices and/or handling devices (3, 4, 7, 8) positioned in the forestry machine and is controlled by a control unit (2). When the control unit in the forestry machine gives one or more work or handling devices a control command starting a change operation, it is transmitted substantially simultaneously to the power source. When arriving at the power source, one or more control commands requiring a power change of the power source affect control parameters of the power source, predicting the future load of the power source.
Claims11
A method for controlling a power source of a forestry machine, in which the power source utilizes directly or indirectly at least one of a work device and a handling device positioned in the forestry machine, said method comprising:
- using a controller to control said at least one of said work device and said handling device;
- the controller giving a control command affecting a state of a function to said at least one of said work device and said handling device;
- transmitting said control command to the power source as a secondary control command, said secondary control command providing an operational change in the power source;
- and
- executing the operational change before operation of said at least one of said work device and said handling device so in such a way that the secondary control command at least momentarily affects at least one control parameter of the power source, predicting a future load of the power source.
