  "text": "Option 2 describes the determination of the torque loss by a combination of measurements and linear interpolation. Measurements shall be performed for the torque independent losses of the transmission and for one load point of the torque dependent losses (maximum input torque). Based on the torque losses at no load and at maximum input torque, the torque losses for the input torques in between shall be calculated with the torque loss coefficient fTlimo .\nThe torque loss Tl,in on the input shaft of the transmission shall be calculated by\nTl,in (nin , Tin , gear) = Tl,in,min_loss + fTlimo * Tin + T l,in,min_el + fel_corr * Tin\nThe torque loss coefficient based on the linear model fTlimo shall be calculated by\nfTlimo=Tl,maxT−Tl,in,min_lossTin,maxTwhere:\nTl,in Torque loss related to input shaft [Nm]\nTl,in,min_loss Drag torque loss at transmission input, measured with free rotating output shaft from testing without load [Nm]\nnin Speed at the input shaft [rpm]\nfTlimo Torque loss coefficient based on linear model [-]\nTin Torque at the input shaft [Nm]\nTin,maxT Maximum tested torque at the input shaft (normally 100 % input torque, refer to 3.2.5.2. and 3.4.4.)
