Abstract
A method for determining the output speed (N_AB) of a manual transmission of a motor vehicle. The output speed (N_AB) is calculated during a period of a shifting operation in which the current gear is disengaged and the new gear has yet to be engaged. The calculated output speed (N_AB) is used for controlling adjustment of the speed of the transmission input shaft (N_EG) to the speed of the transmission output shaft, or the calculated output speed (N_AB), is used for checking the plausibility of a value of the output speed (N_AB) as determined by the sensors.
