Title: CONTROL SYSTEM, WORK MACHINE, AND CONTROL METHOD
Abstract:
A control system is provided with: a first hydraulic pump and a second hydraulic pump; a flow channel connecting the first hydraulic pump and the second hydraulic pump; an opening/closing device provided in the flow channel to open and close the flow channel; a control device for controlling the opening/closing device to switch between a split flow state in which the flow channel is closed and a connected state in which the flow channel is open; a first actuator to which working fluid discharged from the first hydraulic pump is supplied in the split flow state; and a second actuator to which working fluid discharged from the second hydraulic pump is supplied in the split flow state. The control device controls the opening/closing device so that in the connected state, even if either the first actuator or the second actuator is put in a driving state, the connected state is maintained.
