Problems solved by technology

However, Patent Document 3 only calculates the power assist correction amount based on the product of the output value of the steering torque sensor and the output value of the steering rotation speed sensor.
That is, since the steering feeling felt by the user is not determined, and the assist control is performed based on it, there is a problem that the user's discomfort cannot be completely suppressed as in Patent Documents 1 and 2.

Abstract

A sensitivity identifying device has an operating object device configured to operate when an operation member is moved according to a force applied by a user, an assist force applying device for applying an assist force to movement of the operation member, an operation force parameter detecting device for detecting a value of an operation force parameter, an operation response parameter detecting device for detecting a value of an operation response parameter, a sensitivity identifying information storage section for storing sensitivity identifying information associating a sensitivity index, with a combination of the value of the operation force parameter and the operation response parameter, and a sensitivity determining unit for specifying the sensitivity index based on the combination of the value of the operation force parameter and the operation response parameter, and the sensitivity identifying information, and outputting the sensitivity index.

Description

technical field [0001] The present invention relates to an operating system, such as an electric power steering system, which has an operation object device and a power assist attachment device, wherein the operation object device acts in response to a force applied from a user, an operation member moves, and the power assist attachment device acts on the above operation member Apply boost. Background technique [0002] Power steering systems have continued to grow in popularity. Power steering uses oil pressure to assist the rotation of the steering wheel to steer the car. With this power steering system, the driver can steer with less effort. [0003] In response to this, recently, an electric power steering system called EPS (Electric Power Steering) has become widespread. Steering is changing from hydraulic power steering to EPS. Compared with the hydraulic power steering system, EPS has the following advantages. [0004] (1) The components are light and the fuel co...
