Abstract
A control system includes: a first hydraulic pump and a second hydraulic pump; a passage connecting the first hydraulic pump and the second hydraulic pump with each other; an opening/closing device provided in the passage and configured to open and close the passage; a control device configured to control the opening/closing device to switch between a split-flow state in which the passage is closed and a connected state in which the passage is open; a first actuator to which hydraulic fluid discharged from the first hydraulic pump is supplied in the split-flow state; and a second actuator to which hydraulic fluid discharged from the second hydraulic pump is supplied in the split-flow state. In the connected state, the control device controls the opening/closing device so that the connected state is maintained even when either one of the first actuator and the second actuator is brought into a driven state.
