摘要： A steering-angle control apparatus controls a steering mechanism based on a state command value, which is input in each predetermined period. An interpolation unit interpolates between a previous value and a current value of the input state command value to compute a state interpolation value in an interpolation period, which is shorter than the predetermined period. An interpolation-value determination unit determines whether the state interpolation value is an abnormal value. A control unit controls the steering mechanism based on the state interpolation value computed by the interpolation unit when the interpolation-value determination unit determines that the state interpolation value is not an abnormal value, and controls the steering mechanism based on the current value of the state command value when the interpolation-value determination unit determines that the state interpolation value is an abnormal value.

摘要： An assist control unit calculates an assist torque command based on a steering torque. A steering angle control unit calculates a steering angle control torque command so that a steering angle determined according to an output of a motor follows a target steering angle commanded from a lane keeping support device. A vibration application control unit calculates a lane departure warning control torque command to apply vibration to an assist torque when a lane departure warning activation request is notified. A motor drive control unit controls a drive of the motor based on an addition value of the assist torque command, the steering angle control torque command, and the lane departure warning control torque command. The steering angle control unit includes a vibration removal filter configured to remove vibration frequency components of the lane departure warning device in calculations on a steering angle signal loop for steering angle control.

摘要： A servo controller calculates a base assist command, which is a basic command value of the assist torque, so that the steering torque follows a target steering torque. An estimated load torque calculation section calculates an estimated load torque. A target steering torque calculation section calculates a target steering torque using a map that defines a relationship between the estimated load torque and the target steering torque. The estimated load torque calculation section calculates the estimated load torque based on the steering torque or the target steering torque and an estimated load calculation assist command corresponding to a calculation result of only a proportional integral control calculation among the control calculations in the servo controller.
