摘要： A drive plate includes a disk-shaped plate portion; and a tooth-shaped portion formed at an outer peripheral end of the plate portion. The plate portion and the tooth-shaped portion are integrally shaped from a single steel plate material. The plate portion and the tooth-shaped portion include a carburized layer provided over an entire surface layer of the plate portion and the tooth-shaped portion, the carburized layer having a carbon concentration higher than that of a center portion of the plate portion and the tooth-shaped portion in a thickness direction. The carburized layer of the plate portion is higher in hardness than the center portion of the plate portion in the thickness direction. The carburized layer of the tooth-shaped portion has been subjected to a quenching process, and is further higher in hardness than the carburized layer of the plate portion.

摘要： A control unit estimates reverse transfer torque transferred from tires to a steering wheel and calculates an assist gain based on the reverse transfer torque. The control unit calculates basic assist torque demand by multiplying torsion torque detected by a torque sensor by the assist gain. The control unit further calculates assist torque command by adding compensation for stabilization. Since the assist gain is determined based on the reverse transfer torque, actual assist torque is generated in accordance with the force transferred from the road surface. Thus, a driver can operate the steering wheel while feeling the force from the road surface.
摘要翻译：控制单元估计从轮胎转向方向盘的反转传递扭矩，并根据反转传递转矩计算辅助增益。控制单元通过将由扭矩传感器检测出的扭转扭矩乘以辅助增益来计算基本辅助扭矩需求。控制单元通过增加补偿补偿来进一步计算辅助转矩指令。由于辅助增益是基于反向传递转矩确定的，所以根据从路面传递的力产生实际辅助转矩。因此，驾驶员可以在感觉到来自路面的力的同时操作方向盘。

摘要： In a steering system, a generator generates a first commanded value for assist torque, and a converter converts a second commanded value for the assist torque to a commanded current value. A current controller controls a drive current for driving a motor for generating the assist torque. A characteristic limiter is functionally interposed between a commanded-value generator and a converter, and limits, to a preset characteristic range, a characteristic of a functional downstream of the converter in the steering system. The functional downstream of the converter in the steering system includes a steering mechanism including the motor. The commanded-value generator inputs, to the characteristic limiter, the first commanded value. The characteristic limiter determines the second commanded current value for the assist torque based on the characteristic of the functional downstream and the first commanded value.
