Problems solved by technology

[0005] However, when the vehicle is being driven, the torque for supplying hydraulic pressure is too large for an oil pump driven only by electricity, so an electric motor with a large capacity is required, and its installation and design layout accompanying the electric motor and manufacturing cost up is unfavorable
[0006] Also, when the vehicle is driven under extreme conditions, the electric motor consumes too much power

Abstract

A hybrid oil pump system may include a motor connected to an oil pump and supplying torque, an engine disposed to supply torque to the oil pump, and a first one-way clutch disposed in a line through which the torque from the engine may be supplied to the oil pump, and selectively supplying the torque from the engine to the oil pump in accordance with a difference in RPM between the engine and the motor.

Description

technical field [0001] In general, the present invention relates to a hybrid oil pump system, and more particularly, to a hybrid oil pump system and a control method of the hybrid oil pump system, the system during operation by using an electric oil pump instead of a mechanical oil pump. Improves fuel efficiency and improves durability by minimizing engine mechanical friction. Background technique [0002] Vehicles are equipped with various hydraulic devices (such as automatic transmissions) that are operated by hydraulic pressure, and the hydraulic devices generally supply hydraulic pressure through a mechanical oil pump directly connected to the crankshaft of the engine. [0003] A vehicle that needs to travel with the engine stopped, such as a hybrid vehicle, is equipped with an electric oil pump separate from the mechanical oil pump. That is, when the mechanical oil pump is stopped as the engine is stopped, the hydraulic pressure is kept supplied by the electric oil pum...
