Abstract
Torque can be detected in a transmission by using at least one vibration sensor to detect at least one vibration signal which is associated with a tooth engagement frequency of intermeshing transmission toothings, and the phase shift of which is dependent on at least one tooth engagement duration of the intermeshing transmission toothings. The tooth engagement duration is torque-dependent as a result of toothing deformations. A torque acting on the transmission is determined from the phase shift of the detected vibration signal and/or of the at least one tooth engagement duration.
