Abstract
A method is provided for the determination of a torque which is transmitted along a torque transmission path which extends at least along a shaft of a motor vehicle. A rotary position signal is produced by a first speed of rotation sensor at a first section of the transmission path and a rotary position signal is produced by a second speed of rotation sensor at a second section of the transmission path. At a point in time at which a known torque is transmitted along the transmission path, a first rotary position signal relationship is determined with reference to the instantaneously generated rotary position signals, the rotary position signal relationship serving as an offset value. At a later point in time, a second rotary position signal relationship is determined with reference to the instantaneously generated rotary position signals. The transmitted torque is calculated on the basis of the offset value and of the second determined rotary position signal relationship.
