摘要： A control system for a motor vehicle, for outputting a controlled variable, with the aid of which a directly controlled variable of a motor vehicle is adjustable via suitable control operations, in order to adapt the directly controlled variable to a reference variable of the control system. The control system includes a controller, which is configured to output a first output variable on the basis of the directly controlled variable of the motor vehicle, and on the basis of the reference variable of the control system. The control system further includes a predictive model, which may be trained to output a second output variable that reflects a deviation of a driving behavior of a driver of the motor vehicle from the first output variable of the controller. The controlled variable of the control system encompasses an addition of the first output variable and the second output variable.

摘要： A method is for producing, for a hydraulic machine having an actuator, a setpoint-value trajectory satisfying predefined limitations in order to influence an output variable of the hydraulic machine. A trajectory of unlimited setpoint values is fed to a trajectory planning function, which produces the setpoint-value trajectory from the trajectory of unlimited setpoint values. In the trajectory planning function, the trajectory of unlimited setpoint values is differentiated at least twice in order to obtain a trajectory of unlimited setpoint values that is differentiated n times. In the trajectory planning function, at least one limitation is applied to the differentiated trajectory of unlimited setpoint values in order to obtain a differentiated trajectory of limited setpoint values. The differentiated trajectory of limited setpoint values is fed to a filter integrator chain in order to obtain the setpoint-value trajectory.

摘要： The invention relates to a control circuit (27) for a waste heat recovery system (2) for a heat engine (36). The waste heat recovery system (2) comprises at least one evaporator (21) for converting waste heat from the exhaust gas (31, 31a) generated by the heat engine (36) into a working medium (23), at least one expansion machine (24) which can be driven by the working medium (23), at least one condenser (25) for condensing the working medium (23a) expanded in the expansion machine (24) into the liquid state (23b), and at least one conveying device (26) for increasing the pressure of the condensed working medium (23b) and conveying same into the evaporator (21). The control circuit (27) influences at least one control variable which controls the energy transmission from the exhaust gas (31, 31a) to the working medium (23b) and/or the energy transmission from the working medium (23c) to the expansion machine (24). The control circuit (27) is designed to regulate the specific enthalpy hW and/or the temperature TW of the working medium (23c) entering the expansion machine (24) to a target value hW,S, TW,S, wherein the target value hW,S, TW,S depends on the pressure pW of the working medium (23c) entering the expansion machine (24). The invention also relates to a waste heat recovery system (2) for an internal combustion engine of a vehicle (3) in the form of a heat engine (36) comprising the control circuit (27) and to a corresponding computer program.
