摘要： It is an object of the present invention to provide a control unit for an electric power steering apparatus for accurately detecting an abnormality of a steering angle sensor without forming the steering angle sensor as a double system or using an expensive position detection sensor. The object is achieved by calculating a relative steering angle by using inexpensive position detection sensors disposed at a motor of the electric power steering apparatus to output binary values and comparing a change amount of an absolute steering angle detected by the steering angle sensor and a change amount of the calculated relative steering angle with each other to thereby detect the abnormality of the steering angle sensor.

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.

摘要： 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.
