Abstract
A method for operating a drive train () of a vehicle includes, in order to check the plausibility of an adapted charge pressure value, changing an actuating pressure of a starting component () corresponding to an adapted charge pressure value by an offset and ascertaining a resultant change in a torque of an electric machine (). When the change in the torque of the electric machine () and the offset of the actuating pressure correspond to each other within defined limits, a plausible adapted charge pressure value is inferred. When the change in the torque of the electric machine () and the offset of the actuating pressure do not correspond to each other within the defined limits, an implausible adapted charge pressure value is inferred.
