    摘要： An electric steering apparatus includes a posture adjusting mechanism having a motor for adjusting tilt and/or telescopic position of a steering mechanism, a speed command unit for outputting a speed command for position adjustment, a motor control unit having a feed-forward control module into which a speed command outputted from the speed command unit is inputted for controlling the motor, and a disturbance load estimation unit for estimating a disturbance load from a deviation between a load torque based on speed information of the electric motor and a command torque based on the speed command. One of the disturbance load estimation value and a command values which is equivalent to the disturbance load estimation value is positively fed back to an output side of the feed-forward control module. A transfer function of the feed-forward control module is set to a transfer function with which a target speed is obtained.

    摘要： In order to solve a problem that a motor generates a noise so as to deteriorate an environment in a vehicle if a field weakening control is executed to the motor of a electric power steering apparatus, in the case that a vehicle speed is high, the same field weakening control as the conventional one is applied to the motor because a noise generated due to a friction between a tire and a road surface and a wind noise of a vehicle body are large, and in the case that the vehicle speed is low, the field weakening control is weakly applied in comparison with the conventional one because the noise generated by the motor is felt relatively largely. Accordingly, the field weakening control can be executed in response to the vehicle speed in such a manner as to make the motor noise smaller.

    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.
