Abstract: An electric steering control device controls a steering characteristic by outputting an assist torque using a motor, and the assist torque corresponds to a detection value of a steering torque which is applied to a steering shaft. The electric steering control device includes a steering target value generation unit generating a target value of the steering torque based on a state amount estimated from the target value of the steering torque and the assist torque, a command value generation unit generating a command value for controlling the motor to reduce a deviation between the target value of the steering torque and the detection value of the steering torque to a level lower than a predetermined threshold, and a motor drive unit driving the motor based on the command value.
