    摘要： A mobility hub is composed of a plurality of layers and serves as a terminal of a ground mobility and an air mobility. The mobility hub includes: a ground layer provided with an entrance of the ground mobility; a port layer provided with a taking-off and landing site of the air mobility; and a middle layer provided between the ground layer and the port layer. The middle layer has the ground mobility elevating in a space with the ground layer, is provided with a plurality of connection slots to which the ground mobility is connected, and provides an activity space through the ground mobility if the ground mobility is coupled to the connection slot.

    摘要： An electric oil pump control method for operating a transmission of a hybrid vehicle which is driven by a first motor, a second motor, and an engine is provided. The method includes determining a number of revolutions of a low-pressure pump of an electric oil pump based on lubrication flow amount of the first motor, lubrication flow amount of the second motor, cooling flow amount of the first motor, and cooling flow amount of the second motor and determining a number of revolutions of a high-pressure pump of the electric oil pump based on control flow amount of a clutch of the transmission and lubrication flow amount of a rotation driver included in the transmission. A maximum value is determined of the determined number of revolutions of the low-pressure pump and the determined number of revolutions of the high-pressure pump as a number of revolutions of the electric oil pump.

    摘要： A method of checking an abnormality in oil pressure of a transmission control unit (TCU) may include determining whether an oil pressure signal transmitted from the TCU to an electric oil pump (EOP) device is normal, transmitting a specific oil pressure value to the EOP device, the specific oil pressure value being set for determining whether the oil pressure signal transmitted from the TCU is normal, determining whether an oil pressure corresponding to the specific oil pressure value is sensed at the EOP device, determining whether a decrease range of the oil pressure sensed at the EOP device belongs within a predetermined range when compared to the specific oil pressure value, and determining whether to perform abnormality control over a transmission by operating the EOP device at set minimum revolutions per minute when the decrease range of the oil pressure sensed at the EOP device is beyond the predetermined range.
