Steuereinheit für elektrische Servolenkung

Provides a control unit for an electric power steering apparatus with improved steering performance by recognizing a turn and a return of a steering wheel in a steering wheel return control, and by employing information on a steering angular velocity in calculating a current. This control unit 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. A steering wheel return controller for applying a steering wheel return control signal to the steering assist command value is provided, thereby to execute the steering wheel return control only when the steering wheel returns.
