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

The present invention relates to a method () for actuating an electric machine () in the motor starting mode by means of a power electronic system (), in particular for application in a motor vehicle, wherein the power electronic system () has a multiplicity of controllable power switches which are designed to supply the electric machine () with electric current (l_s), wherein a total amount of energy () which is required to reach a predefined rotational speed (n_crit) and a time period (t) for reaching the predefined rotational speed (n_crit) is estimated (), wherein a setpoint torque (M) for starting the electric machine () is determined () on the basis of the estimated total amount of energy () and the estimated time (t), and wherein the power electronic system () is actuated () in accordance with the setpoint torque (M).
