Abstract
The present invention discloses a method for controlling an electric machine, having an encoder wheel which has a multiplicity of teeth and at least one reference marking, having the steps: detecting the dynamics of the electric machine, detecting the positions of the teeth on the encoder wheel in relation to the at least one reference marking if the electric machine exhibits low dynamics, calculating a rotational speed of the electric machine on the basis of at least the detected positions, and controlling the electric machine on the basis of at least the calculated rotational speed. Furthermore, the present invention discloses a drivetrain and a vehicle.
