Problems solved by technology

[0005] However, since a torque sensor has broken down, the stability of the torque signal output by the torque sensor (for measuring the driver's steering torque) cannot be guaranteed, and thus, the power steering may be erroneously controlled, or the power steering may not be completed. control, such that it can lead to serious traffic accidents
[0006] Despite these problems, the power steering control method in the prior art suddenly stops providing a steering assist force when the torque sensor has failed, thus causing a sense of difference in the power steering and failing to provide the driver with sufficient time. to face failure
Further, when the torque sensor has failed, the power steering control method in the prior art only stops providing steering assist force, and cannot provide a method for continuously providing steering assist force

Embodiment Construction

[0025] A power steering control method and a power steering control device will be disclosed below.

[0026] Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing components of the present invention, terms such as first, second, A, B, (a), (b) and the like may be used. These terms are only for distinguishing a structural element from other structural elements, and attributes, order, sequence, etc. of a corresponding structural element should not be limited by the terms. It should be noted that when it is described in the specification that one component is "connected", "coupled" and "engaged" with another component, although it is stated that the first component may be directly "connected", "coupled" and "engaged" with the second component , a third component may also be "connected", "coupled" and "engaged" between the first component and the second component.

Abstract

The present invention relates to a method and apparatus for controlling electric power steering. In particular, the present invention provides a power steering control method that includes: a breakdown detection step of detecting whether a torque sensor has broken down; an information reception step of receiving steering angle information and vehicle speed information in the case in which the torque sensor has broken down; a compensation target value calculation step of calculating a self-aligning torque, and a damping force, an inertial force, and a frictional force of an electric power steering apparatus by using one or more of the steering angle information and the vehicle speed information; and a current control step of calculating a steering assist force based on the compensation target value and controlling the supply of a motor control current that corresponds to the steering assist force, and an apparatus for the same.

Description

technical field [0001] The invention relates to a control method and a control device for electric power steering. More particularly, the present invention relates to a power steering control method and a power steering control device capable of continuously providing power even when a torque sensor has failed by using a motor in an electric power steering control device. One steering assist. Background technique [0002] The electric power steering control method refers to a power steering control method that uses a steering assist force generator (eg, a motor) to assist a driver's steering force. For example, the electric power steering control method refers to a system that measures a driver's steering torque, calculates a steering assist force corresponding to the steering torque, and to provide the steering assist force. [0003] Such an electric power steering control method helps the driver use less force to complete the steering operation, and provides different s...
