A method for operating a receiving unit of a communication network to recognize an erroneous transfer of useful data. The method includes: temporally consecutively receiving a multitude of data packets sent using the sending unit, each of the data packets encompassing useful data including an adapted value of a variable; the adapted values having been ascertained using the sending unit of the communication network, based on a received value of the variable and an adaptation value ascertained using an adaptation rule; and the adaptation values for values of the variable which are temporally consecutively received using the sending unit being different; and recognizing an erroneous transfer of the adapted values of the variable encompassed by the useful data using the receiving unit when the values of the variable, encompassed by a predefined number of temporally consecutively received data packets, differ by less than a predefinable or predefined threshold value.

Method for operating units of a communication network

A method for determining a value of a brake pressure modulated by a pneumatic channel of a braking value encoder having at least one electrical channel, in a braking device of a vehicle, including: (a) a first characteristic curve, in which the dependence of the signals, modulated by the at least one electrical sensor, on the degree of activation of the braking value encoder is represented, is determined and stored; (b) a second characteristic curve, in which the dependence of the brake pressure values, modulated by the channel, on the electrical signals detected by the sensor is represented, is determined and stored; and (c) the brake pressure value corresponding to a specific braking request as a result of activation of the encoder is determined based on the first and second characteristic curves.
