Abstract: Model-based predictive control (MPC) of a motor vehicle involves an MPC algorithm, which comprises a high level solver module to calculate a high level longitudinal trajectory for an upcoming route segment, according to which the motor vehicle is to travel within a route-based high level prediction horizon. The high level longitudinal trajectory is sent to a tracker solver module in the MPC algorithm as an input value, which calculates a tracker longitudinal trajectory on the basis of the high level longitudinal trajectory, according to which the motor vehicle is to travel within the time-based tracker prediction horizon, wherein the tracker prediction horizon is shorter than the high level prediction horizon, such that the tracker prediction horizon only covers a portion of the high level prediction horizon.

Abstract: A hydraulic actuating device for actuating a shifting element of a transmission includes a hydraulic cylinder with a piston rod and a piston chamber, wherein the piston rod can be brought into a mechanical operative connection with the shifting element, and a hydraulic pump which is connected via a hydraulic line to the piston chamber, in order for it to be possible for hydraulic fluid to be fed to the piston chamber and thus to initiate an adjusting movement of the piston rod. The actuating device is characterized by a shut-off device, via which the hydraulic fluid can be locked in the piston chamber, in order thus to fix the position of the piston rod.
