摘要： A variable transmission ratio steering apparatus for a vehicle is configured with an input shaft coupled to a steering wheel of the vehicle, a sensor for sensing a rotation angle of the input shaft, an output shaft operatively linked to steerable road wheels of the vehicle, an actuator having an electric motor which is configured to vary a transmission ratio between a rotation angle of the output shaft and the rotation angle of the input shaft, and a controller. More specifically, the controller includes a desired rotation angle calculation unit, a difference calculation unit, and a difference limitation unit, whereby a rotation angle of a rotor of the electric motor is limited. With such a configuration, a rotation speed of the rotor of the electric motor can be limited by limiting the rotation angle of the rotor, and consequently, audible operation noises arising from the electric motor can be minimized.

摘要： A fault detection unit detects a fault occurred in a detecting device which detects a rotational angle of a rotor with respect to a stator from sine and cosine wave signals having amplitudes modulated in a sinusoidal wave shape in a cycle of rotation of the rotor. The unit produces a judging value from the signals, judges occurrence of a fault from the value placed out of a normal range, and judges the device to be in a tentative fault state when the judgment is continued. After this judgment, when the rotational angle is changed over its entire range while the value is placed within the normal range, the unit judges the device to have returned to a normal state. In contrast, when the judgment is still continued, the unit judges the device to be in a determinate fault state and decides the occurrence of the fault.
