METHOD FOR DETERMINING THE TORQUE AND/OR ANGULAR SPEED OF A ROTATING SHAFT AND A DEVICE FOR CARRYING OUT SAME

摘要

A method allowing the reliable and accurate calculation of the torque of a shaft using two phonic wheels and a sensor, the method including correlating the signal resulting from a rotation or one sixth of a rotation with the signal resulting from the subsequent rotation or one sixth of a rotation. The length of time between two passages of teeth is calculated by interpolating the cross-correlation function using least squares interpolation.
