A processor unit () for model-based predictive control of a vehicle () taking into account an arrival time factor is configured to calculate a trajectory for the vehicle () based at least in part on at least one arrival time factor, with the trajectory including an entire route () to a specified destination () at which the vehicle () is to arrive, and with the at least one arrival time factor influencing an arrival time of the vehicle () at the specified destination (). Additionally, the processor unit () is configured to optimize a section of the trajectory for the vehicle () for a sliding prediction horizon by executing a model-based predictive control (MPC) algorithm (), where the MPC algorithm () includes a longitudinal dynamic model () of a drive train () of the vehicle () and a cost function () to be minimized.

Model-based predictive control of a vehicle taking into account a time of arrival factor

A device () for determining a discrete representation () of a road section ahead of a vehicle () includes an input interface () for receiving sensor data () of a sensor () with information about the road section ahead of the vehicle, a setting unit () for ascertaining a control distance at which a property of the road section ahead of the vehicle that is relevant for an open-loop control of the vehicle changes based on the sensor data and for setting a support point in a discrete representation of the road section corresponding to the control distance. The setting unit is configured for setting a lower predefined second number (n) of support points based on a predefined first number (n) of support points. The device also includes an output interface () for outputting the lower predefined second number of support points to an optimizer () in order to determine a profile of at least one control parameter for the open-loop control of an open-loop system, a vehicle function based on the second number (n) of support points.
