DEVICE AND METHOD FOR ADJUSTING ELECTRIC POWER STEERING DEVICE.

摘要

A device for adjusting an electric power steering device comprises: a steering mechanism for converting input torque into a steering force and transmitting the steering force to wheels; a torque sensor for outputting a torque detection signal according to input torque; an electric motor for applying steering assisting torque according to the torque detection signal outputted by the torque sensor; a sensor circuit by which the output characteristics of the torque sensor is changed; an actuator for applying input torque to the steering mechanism; a steering force measurer for operating the electric motor through the torque sensor according to input torque and measuring the steering force outputted by the steering mechanism; and a sensor output adjuster for adjusting, according to the amount of the deviation calculated on the basis of the difference between a preset ideal value and the steering force measured by the steering force measurer, the output characteristics of the sensor circuit so as to bring the steering force close to the ideal value.
