Example embodiments relate to a method and a control unit, wherein a drive system having an electric machine and having an internal combustion engine with at least a first cylinder and a crankshaft is provided. A fuel feed to at least the first cylinder of the internal combustion engine is deactivated, wherein the electric machine is coupled fixedly in terms of torque to the internal combustion engine. The electric machine is actuated such that the crankshaft of the internal combustion engine rotates at a predefined rotational speed, wherein a first cylinder segment time duration, which is assigned to the first cylinder, is detected. A corrective value is determined in a manner dependent on the first cylinder segment time duration.
