An apparatus for controlling an electric oil pump (EOP) includes a controller calculating first revolutions per minute (RPM), second RPM and third RPM, the first RPM being EOP RPM required for control of a brake in a transmission, the second RPM being EOP RPM required for cooling of a plurality of motors, and the third RPM being EOP RPM required for lubrication of the plurality of motors, the controller comparing the second RPM with the third RPM and driving the EOP at an RPM obtained by adding the first RPM to the greater of the second RPM and the third RPM.

Apparatus and method for controlling electric oil pump

A method for controlling a motor includes detecting output signals output from three phases of a hall sensor, determining a failure of the hall sensor depending on the output signals, diagnosing which of the three phases of the hall sensor is out of order based on the output signals if it is determined that the hall sensor detections deviate from a predicted order, and outputting a virtual signal for the phase which is determined as a failure among the three phases of the hall sensor to a motor controller.

Method for controlling a motor

A method for diagnosing abrasion of an electric oil pump rotor includes sensing a driving duty of an oil pump control unit, and determining whether the sensed driving duty of the oil pump control unit is below a set reference value, wherein as a result of the determining, when the driving duty of the oil pump control unit is below the set reference value, it is determined that the electric oil pump rotor is in a worn out state.

Method for diagnosing abrasion of electric oil pump rotor

A system and method of controlling an automotive electric oil pump are provided. The method of controlling an oil pump can minimize power consumption of a vehicle and improve the fuel efficiency accordingly by learning the performance of the electric oil pump and operating the electric oil pump based on performance.

Control method for oil pump

An oil pump control apparatus of a hybrid vehicle is provided that controls an oil pump according to a demand of an output torque and oil temperature. In particular, hydraulic line pressure is controlled by operating an oil pump at maximum power if a starting demand for a hybrid vehicle is detected. Viscosity is calculated as well to correspond to an oil temperature in an engine stop mode and a rotation speed of the oil pump is controlled at a low power. Additionally, viscosity is also calculated according to a variation of a line pressure in a driving mode and the rotation speed of the electric oil pump is controlled in either a low power, a middle power, and a high power state as well.
