摘要: To accurately extract a pulsating component generated due to a cogging torque or a torque ripple to reduce a pulsation, the pulsating component is extracted using a bandpass filter having a variable time constant, and the time constant is set according to a frequency of cogging torque or torque ripple to be extracted. Further, a reference angle for a rotation angle of a motor is preset according to a generation harmonic order of the cogging torque or torque ripple, and the time constant of the bandpass filter is set from a time period required for the motor to rotate by the reference angle.

摘要: An automatic steering apparatus that can suppress steering wheel vibration and that can also smooth angular control. In the automatic steering apparatus, a motor that steers steered wheels is controlled by a control unit. Information from an angle sensor that generates a signal that corresponds to a steering angle of the steered wheels is sent to the control unit. The control unit corrects a target steering angle of the steered wheels such that angular acceleration of the target steering angle is less than or equal to a limiting value. The control unit controls the motor such that the steering angle of the steered wheels tracks the corrected target steering angle based on the information from the angle sensor.

摘要: In the control of an electric power steering apparatus, where so-called lead steering control is performed in which a steering wheel angle signal is output through a lead filter to correct reaction delay of a driver and a vehicle, a delay in control response occurs due to feedback of a road surface reaction force torque. When road surface reaction force torque is fed back to the steering wheel, it is added through a low-pass filter having a time constant equal to a reaction delay time constant of a driver. A sum signal is output through a lead filter to a second motor for controlling a steering shaft.
