Abstract
A steering control device is provided, which comprises a motor driving circuit for driving a motor and a microprocessor for supplying an applied voltage signal, which is found based on a motor current detection value detected by a motor current detecting unit, a motor voltage detection value detected by a motor voltage detecting unit, a steering torque detected by a torque sensor and a vehicle speed detected by a vehicle speed sensor, to the motor driving circuit such that the motor driving circuit increases or decreases the motor current according to an average value of motor current detection values over a time period and increases or decreases the motor current by detecting that a steering is in the vicinity of a maximum steering angle based on the detected steering torque.
