Patent ID: 7559259

Claim:
A method for the determination of a torque which is transmitted along a torque transmission path which extends along at least a shaft of a motor vehicle, comprising: producing a rotary position signal by means of a first speed of rotation sensor at a first section of the transmission path and by means of at least one second speed of rotation sensor at a second section of the transmission path, wherein 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 generated rotary position signals, said rotary position signal relationship serving as an offset value; and at a later point in time, a second rotary position signal relationship is determined with reference to the generated rotary position signals, with the torque transmitted being calculated on the basis of at least the offset value and of the second determined rotary position signal relationship, wherein a respective rotary position signal relationship is determined for a plurality of points in time with reference to the respective generated rotary position signals, with a play value of the transmission path being determined in that a maximum difference is determined between the rotary position signal relationships determined for the plurality of points in time and in that the transmitted torque is calculated on the basis of at least the offset value of the second determined rotary position signal relationship and of the play value.
