1. A processor unit (3) for model predictive control, MPC, of a motor vehicle (1) that includes a cooling pump (28), operable with different pump operating values (Q1, Q2, Q3) of at least one operating parameter (30), wherein:
the processor unit (3) configured for executing an MPC algorithm (13) for model predictive control of the motor vehicle (1), the MPC algorithm (13) comprising a longitudinal dynamic model (14) of the motor vehicle (1) and a cost function (15) to be minimized, the cost function (15) comprising a plurality of terms, including a first term representing an output of the cooling pump (28); and
the processor unit (3) is configured for, by executing the MPC algorithm (13), ascertaining a speed trajectory of the motor vehicle (1) situated within a prediction horizon as a function of the longitudinal dynamic model (14), and
simultaneously ascertaining a pump operating value trajectory situated within the prediction horizon such that the first term of the cost function (15) is minimized,
controlling a drive train of the motor vehicle (1) based on the speed trajectory of the motor vehicle (1), and
controlling a pump of the motor vehicle (1) based on the pump operating value trajectory.
