Abstract
A control device includes a current command value calculation unit configured to calculate a first current command value causing an actuator to generate steering assist torque, a correction value calculation unit configured to, when an absolute value of steering angle is greater than or equal to a threshold value, calculate a correction value for suppressing increase in an absolute value of the steering angle by correcting the steering assist torque, a correction unit configured to calculate a second current command value obtained by correcting the first current command value by the correction value, and a driving unit configured to drive the actuator, based on the second current command value. The correction value calculation unit calculates the correction value, based on first torque, the first torque changing nonlinearly with respect to steering angular velocity.
