Method and apparatus are disclosed for vehicle calibration based upon performance product detection. An example vehicle includes a receiver to receive a wireless signal from a transducer of an performance product that includes characteristics of the performance product. The example vehicle also includes a product controller to authenticate the performance product based upon the wireless signal and send, upon authentication, a calibration instruction that includes the characteristics. The example vehicle also includes an electronic control unit to receive the calibration instruction and adjust a calibration to a target setting based upon the characteristics.

A method for operating a drive train (1) of a vehicle includes, in order to check the plausibility of an adapted charge pressure value, changing an actuating pressure of a starting component (7) corresponding to an adapted charge pressure value by an offset and ascertaining a resultant change in a torque of an electric machine (3). When the change in the torque of the electric machine (3) 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 (3) 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.

A method for evaluating a transmission device using various characteristic values, wherein said characteristic values can be determined by means of variable or constant parameters.
