Indirect determination of the torque acting on a rotating component, e.g. for use in automotive applications, by measurement of another parameter, e.g. force, at two or more operating points and plotting a resultant interpolation

摘要

Method for determining the torque acting on a rotating component using at least a sensor for measuring at least a torque-dependent measurement value. According to the method, the measurement value is measured at, at least two, selected operating points (BP1, BP2). The, at least two, measurement values are determined and used, by interpolation, to form a operating curve (A) representing the torque (M). The torque at a particular point is determined using the operating curve. An independent claim is made for a device for measuring the torque acting on a rotating component, e.g. using a force sensor operating of a Cardan shaft. The force is measured at at least two well defined points where it can be related to a torque.
