    Abstract: A method of estimating a torque of a transmission clutch may include adjusting an error, deducing an estimated engine angular speed and deducing an estimated clutch torque. The error may be adjusted by deducing an engine transient torque based on an engine angular speed measured using a sensor, an engine static torque deduced using a data map and a load torque depending on a driving load. The estimated engine angular speed may be deduced based on the engine static torque and the engine transient torque. The estimated clutch torque may be deduced by summing an integration value and an error compensation value. The integration value and the error compensation value may be deduced based on a difference between the estimated engine angular speed and the measured engine angular speed.

    Abstract: A bearing comprises a Bragg grated optical fiber to measure one or more parameters of the bearing. The optical fiber is coupled to the bearing in such a way that at least a part of the optical fiber that comprises Bragg grating is curved. The grating which is curved is adapted to the curvature in such a way that the frequency response is well defined and not spread out. This is achieved by arranging the gratings such that even though the fiber is curved the gratings appear to be substantially parallel instead of being influenced by the curvature.
