Abstract
A power system including: a power unit, a supply pump for feeding liquid oil for lubricating the power unit; a supply flow path for guiding, to the power unit, the oil fed from the supply pump; a return pump for returning the oil having flowed through the power unit; a return flow path for guiding, to the return pump, the oil having flowed through the power unit; a circulation flow path for guiding, to the supply pump, the oil returned by the return pump; a bypass flow path connecting the supply flow path and the return flow path; and an on-off valve for opening and closing the bypass flow path.
Claims11
A power system comprising:
- a power unit;
- a supply pump configured to feed oil in a liquid form for lubricating the power unit;
- a supply flow path configured to guide, to the power unit, the oil fed from the supply pump;
- a return pump configured to return the oil having flowed through the power unit;
- a return flow path configured to guide, to the return pump, the oil having flowed through the power unit;
- a circulation flow path configured to guide, to the supply pump, the oil returned by the return pump;
- a bypass flow path connecting the supply flow path and the return flow path;
- and
- an on-off valve configured to open and close the bypass flow path.
A method of controlling a power system, wherein the power system comprises:
- a power unit;
- a supply pump configured to feed oil in a liquid form, for lubricating the power unit;
- a supply flow path configured to guide, to the power unit, the oil fed from the supply pump;
- a return pump configured to return the oil having flowed through the power unit;
- a return flow path configured to guide, to the return pump, the oil having flowed through the power unit;
- a circulation flow path configured to guide, to the supply pump, the oil returned by the return pump;
- a bypass flow path connecting the supply flow path and the circulation flow path;
- an on-off valve configured to open and close the bypass flow path;
- a motor configured to drive the supply pump and the return pump;
- and
- a controller comprising one or more processors that execute computer-executable instructions stored in a memory,
- the method comprising:
- causing, by the one or more processors executing computer-executable instructions, the controller to control the motor to set torque of the motor to predetermined target torque in a state where the on-off valve is opened.
