Abstract: A sheet post-processing apparatus includes a first conveying member, a processing tray, a first processing unit, a reference plate, an alignment member, a home-position detection unit, a drive unit, and a control portion. The alignment member has a shaft joined to a drive unit to rotate, and one or more alignment paddles protruding in a radial direction of the shaft. The control portion calculates a contact assumed interval in which the trailing end of the sheets may make contact with the alignment paddle and an interference timing at which the alignment paddle interferes with a carry-in path of the sheets. If the interference timing falls within the contact assumed interval, the control portion temporarily changes the rotation speed of the alignment member from a reference speed to shift the phase of the alignment paddle so that the interfere timing falls outside the contact assumed interval.

Abstract: The actuator control device includes an assist control circuit for calculating a first assist component and an automatic steering control circuit for calculating a second assist component. The automatic steering control circuit is allowed to calculate the second assist component while a steering torque is less than a first threshold value. The automatic steering control circuit calculates the second assist component by performing PID control that uses an integral term obtained on the basis of an angle deviation. When the steering torque is less than the first threshold value but not less than a second threshold value, the automatic steering control circuit limits the integral term in such a manner that it is harder for the integral term to increase while the steering torque is not less than the second threshold value than while the steering torque is less than the second threshold value.

Abstract: An electric power steering apparatus includes a motor for applying assist torque to a vehicle steering mechanism and a controller, which controls driving of the motor to cause the assist torque to follow an assist command value. The controller calculates a basic assist command value based on steering torque applied to the steering mechanism and corrects the basic assist command value using a correction value, thereby setting the assist command value. If the steering torque has an absolute value greater than a threshold value when the vehicle is in a straight-line traveling state, the controller sets the correction value such that the absolute value of the steering torque is reduced. If the steering torque has an absolute value less than the threshold value when the vehicle is in a straight-line traveling state, the controller sets the correction value such that the absolute value of the assist command value is reduced.

Abstract: An electric power steering apparatus is provided which can suppress the difference in steering feel between before and after it is allowed to compute an absolute steering angle and which can improve the steering feel. A basic assist control unit sets a basic assist current value. An assist gain setting unit sets assist gain. The assist gain is fixed to a lower limit value less than one before it is allowed to compute the absolute steering angle, and is gradually increased from the lower limit value to one and is then fixed to one after it is allowed to compute the absolute steering angle. An assist gain multiplication unit corrects the basic assist current value by multiplying the basic assist current value by the assist gain.
