Abstract (en)

[origin: EP3480463A1] An electric oil pump device (10) includes an electric oil pump (10) driven by a motor (11) and a microcomputer (30) that adjusts a control parameter (Kp, Ki, Kd) of feedback control related to a motor current value (Im) or a motor rotation speed (N) based on an oil temperature (Te) estimated based on a relationship between at least one of a hydraulic pressure, the motor current value, or a torque of the electric oil pump (10) and at least one of an oil discharge amount or the motor rotation speed of the electric oil pump.
