METHOD AND APPARATUS FOR ESTIMATION OF AUTOMOTIVE CLUTCH TORQUE

摘要

The present invention relates to a method and a device for the estimation of torque of an automotive clutch, and more specifically, to a method and a device for the estimation of torque of an automotive clutch, wherein the torque of an automotive clutch is estimated by using only a measurement signal capable of being obtained from an existing vehicle without using a torque sensor or other additional sensors. According to the present invention, the torque of an automotive clutch is estimated by using only a measurement signal capable of being obtained from an existing vehicle without using a torque sensor or other additional sensors. In other words, a torque predictor is firstly designed using measured values from a speed sensor and the integral of their difference and then is designed using an engine torque value as additional information, thereby improving the accuracy of the estimation outcome value of the torque of an automotive clutch.
