The fluid pump includes a rotor rotated by the rotating shaft, and a case. The case includes a discharge port configured to allow a fluid to be discharged therethrough, and the discharge port is provided on an inner peripheral surface of an insertion hole through which the rotating shaft is inserted. The rotating shaft includes an attachment portion fittable to a shaft hole, and an internal flow path configured to allow the fluid to flow therethrough. A supply groove is provided on an outer peripheral surface of the rotating shaft, and the supply groove communicates with the internal flow path. The fluid pump is attached to the attachment portion of the rotating shaft such that positions of the discharge port and the supply groove in an axial direction of the rotating shaft overlap each other.

摘要： A control method and apparatus may be applied to an electric drive system. The electric drive system includes an oil pump, a motor, a reducer, and a housing, the motor and the reducer are disposed in the housing, lubricating oil is stored in the housing, and the oil pump is configured to pump the lubricating oil. The method includes: obtaining a first rotational speed of the motor, a second rotational speed of the oil pump, and a temperature of the lubricating oil in the housing; and controlling a rotational speed of the oil pump to be a third rotational speed based on the first rotational speed, the second rotational speed, and the temperature. In this way, the rotational speed of the oil pump can be adjusted to change liquid levels of the lubricating oil in a cavity and oil pump power at different rotational speeds of the oil pump.

摘要： Since the oil pump and the oil cooler are provided in the rear cover and the cooling oil passages for guiding the oil to the respective electric motors MG are integrated in the rear cover, the cooling oil passages do not pass through other case members other than the rear cover. As a consequence, it is possible to shorten the cooling oil passage through which the oil is guided to the respective electric motors MG.
