    摘要: A steering apparatus for vehicle comprises a steering shaft including a first portion connected to a steering member and a second portion connected to steerable wheels; a transmission ratio variable mechanism capable of varying a transmission ratio as a ratio of a steered angle of the steerable wheels to a steering angle of the steering member; and a reaction-force compensation motor for compensating a steering reaction force of the steering member caused by the operation of the transmission ratio variable mechanism. The transmission ratio variable mechanism includes a differential mechanism for differentially rotatably interconnecting the first and second portions; and a differential-mechanism motor for driving the differential mechanism. Both an axis of a rotary shaft of the differential-mechanism motor and an axis of a rotary shaft of the reaction-force compensation motor are aligned with an axis of the steering shaft.

    摘要: A steering shaft is composed of an upper shaft, a lower shaft, an input shaft, and an output shaft. The upper shaft, the lower shaft, and the input shaft can rotate together, and the input shaft and the output shaft are relatively rotatably coupled to each other via a torsion bar. The rotational position of a rotor coupled to the output shaft is calculated based on the detected rotational position of the lower shaft and a steering torque detected based on the amount of relative rotational displacement of the input shaft and the output shaft. Thus, it is not necessary to include a rotor rotational position detecting unit for detecting the rotational position of the rotor within the electric motor, which reduces the size of the electric motor.
