The invention relates to a control circuit () for a waste heat recovery system () for a heat engine (). The waste heat recovery system () comprises at least one evaporator () for converting waste heat from the exhaust gas () generated by the heat engine () into a working medium (), at least one expansion machine () which can be driven by the working medium (), at least one condenser () for condensing the working medium () expanded in the expansion machine () into the liquid state (), and at least one conveying device () for increasing the pressure of the condensed working medium () and conveying same into the evaporator (). The control circuit () influences at least one control variable which controls the energy transmission from the exhaust gas () to the working medium () and/or the energy transmission from the working medium () to the expansion machine (). The control circuit () is designed to regulate the specific enthalpy hand/or the temperature Tof the working medium () entering the expansion machine () to a target value h, T, wherein the target value h, Tdepends on the pressure pof the working medium () entering the expansion machine (). The invention also relates to a waste heat recovery system () for an internal combustion engine of a vehicle () in the form of a heat engine () comprising the control circuit () and to a corresponding computer program.

Control circuit for waste heat recovery systems

The invention relates to a method for generating a control variable trajectory for an actuator so as to influence an input variable of a system, wherein a set point is supplied to the output variable of the system of a trajectory planning procedure, which from the set point generates a trajectory of constrained input values for a filter integrator chain and a trajectory of flat desired states, wherein the trajectory of constrained input values and the trajectory of flat desired states are supplied to a flatness-based feedforward control procedure that generates therefrom the control variable trajectory for the actuator, wherein in the trajectory planning procedure so as to generate the trajectory of constrained input values at least one constraint is applied in dependence upon the trajectory of flat desired states.

A method for parameterizing a functional software of a vehicle, including: receiving information about a vehicle state, transmitting the information about the vehicle state via a communication interface addressed to a remote processing unit outside the vehicle, and receiving, at the local processing unit in the vehicle, information about at least one parameter for influencing the vehicle behavior, which was transmitted by the remote processing unit outside the vehicle, via the communication interface.

A method for operating a supercharging device for an internal combustion engine, the supercharging device being supported as an exhaust gas-driven supercharging device by an electric motor-driven supercharger drive or being operated exclusively by the electric motor-driven supercharger drive, the electric motor-driven supercharger drive being operated as a function of a setpoint actuating torque, the setpoint actuating torque being determined as a function of a pilot control torque from a pilot control unit and a control actuating torque from a rotational speed control unit.

A method for ascertaining the rotor temperature of a permanent-magnet synchronous machine (), in which a first estimate (T) for the rotor temperature is ascertained as a function of a remanent flux density of permanent magnets contained in a rotor of the synchronous machine (). A second estimate (T) for the rotor temperature is ascertained via a Kalman filter containing a thermal model of the synchronous machine (), the first estimate (T) for the rotor temperature being supplied at least intermittently to the Kalman filter.
