Title:
電動パワーステアリングシステム
Document Type and Number:
Japanese Patent JP4807422
Kind Code:
B2
Abstract:
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.
