A method for determining a secure regeneration torque of an electric machine

A method for determining a safe Rekuperationsmoments an electric machine (EM) in a hybrid powertrain (HY) of a vehicle, the hybrid drive train (HY) at least comprising a drive member (VM), an electric machine (EM), a storage element (B) a control unit (e) and a transmission (G), wherein the drive member (VM), the electric machine (EM), the memory element (B), the transmission (G) and the control unit (e) are connected in signal communication with each other, and a gear ratio of the transmission (G) is determined redundantly by a first calculation method and a second method of calculation, being different from the first calculation method and the second method of calculation, characterized in that a to Share recovery torque is reduced when in an adjustment of the transmission ratio (1) first calculation method with the ratio (2) of the second calculation method, an F Ehler signal is detected.
