摘要:
A permanent-magnet type rotating electrical machine, including a rotor including a plurality of magnetic poles arranged at an equal interval, and a stator including a plurality of teeth and a plurality of armature windings. A high frequency voltage different in frequency and amplitude from voltages for generating a torque is applied to the armature windings. A magnetic pole position of the rotor is estimated by using a current trajectory of a measured high frequency current. When dq transform is applied to the measured high frequency current, a current trajectory forms an ellipse on d and q axes. Angular variation ranges of a major axis of the ellipse with respect to a load current and a rotor position are set so as to acquire a predetermined position estimation resolution.

A vehicle electro-hydraulic power steering unit includes: a steering mechanism steering a steering wheel in a steering direction; an electro-hydraulic pump; a piston mechanism assisting the steering mechanism in a steering direction; a hydraulic circuit causing an assist force to be generated in response to the steering of the steering mechanism; and a control unit controlling a motor based on an output signal from a vehicle speed sensor, a torque sensor, and a steering angle sensor. In this power steering unit, driving the motor is started when a steering torque exceeds a set torque threshold, and the torque threshold to be set is changed depending on operating conditions. Thus, a vehicle electro-hydraulic power steering unit improved in fuel consumption is obtained.
