<p>The invention provides a steering control device and a steering speed detection method and aims to obtain a steering speed free from an offset error. The steering control device comprises a steering speed calculation part (12) used for obtaining a first steering speed based on detection values of a current form a current sensor (9) and a voltage from a voltage sensor (10), calculating a modified value of the first steering speed based on a detection value of a steering angle, modifying the first steering speed by the utilization of the modified value and outputting the modified first steering speed as a steering speed; a first steering auxiliary torque calculation part (15) used for obtaining a first steering auxiliary torque for enabling a steering system to return to a central position based on the steering speed; a second steering auxiliary torque calculation part (17) used for obtaining a second steering auxiliary torque for assisting the steering of a driver based on a steering torque of the driver from a torque sensor (5); and a current driver (19) used for driving a motor based on the first and the second auxiliary torques.</p> |
