摘要： A control unit for an electric power steering apparatus can obtain continuous, stable and comfortable feeling of steering, for improved steering, based on a provision of a continuous hysteresis characteristic using a low-cost structure on software. For this purpose, the control unit for an electric power steering apparatus controls a motor for giving steering assist force to a steering mechanism based on a current control value calculated from a steering assist command value calculated based on the steering torque generated in the steering shaft, and a current value of the motor. The control unit includes an assist calculating unit that differentiates a signal of the steering torque, adds the differentiated value to the steering assist command value, and continuously changes the differential gain according to the steering torque and the size of the vehicle speed.
