STEERING CONTROL DEVICE

摘要

This steering control device is provided with: a current command value (1) calculating unit (11) for calculating a current command value (1) based on vehicle speed and steering torque; a current command value (2) calculating unit (14) for calculating a current command (2) based on the differential value of the filtered steering torque; and a current drive unit (10) for driving a motor (5) such that the total of the current command value (1) and the current command value (2) matches the value of a current flowing through the motor (5). When a first crossover frequency is defined as being the crossover frequency of open-loop control characteristics of the steering control device in the case where the differential value of the non-filtered steering torque is used to calculate the current command value (2), the notch frequency of a notch filter that performs the filtering is set larger than the mechanical resonance frequency of the steering control device and lower than the first crossover frequency.
