Further should be under "at least one Parameter "in particular a predetermined parameter and / or a predetermined parameter set be understood, the parameter set preferably of several Parameters is formed. The and / or the parameters can in this case of a parameter for a type of drive, such as in a hybrid drive, a Parameters for a performance limit for the different drive types, one parameter for one Nominal charge state for an energy storage device, such as an automotive traction battery and / or a vehicle electrical system battery, a parameter for a permissible Operating area for charging an energy storage device, a parameter for a transmission shift program, a parameter for a transmission target ratio, a parameter for a control value for further, drive-independent Components, such as for an air conditioner, a pump, a fan, etc., be formed. Due to the inventive design can advantageously be an efficient use of energy and / or a fuel in the operation of the drive unit or an efficient Energy management along the route, in particular the expected Driving route to be reached. Preferably, this can be an energy consumption and / or a fuel consumption advantageous to a profile, in particular a speed profile and / or a pitch profile and / or other, the expert appears reasonable profiles, the expected Driving route to be adjusted.
Vorzugsweise weist die Steuervorrichtung eine Einheit zu einem Erfassen einer Fahrtroute, insbesondere einer voraussichtlichen Fahrtroute, auf, wie beispielsweise eine Navigationseinheit.Preferably the control device has a unit for detecting a Travel route, in particular a probable route, on how for example, a navigation unit.
Vorzugsweise weist das Fahrzeugsystem eine Antriebseinheit auf, die zumindest teilweise von einer Hybridantriebseinheit gebildet ist.

It can be here particularly advantageous several, especially different types drive units, such as an internal combustion engine, an electric motor, etc., in terms of efficient utilization and / or low total energy consumption.
Des Weiteren wird vorgeschlagen, dass die Betriebssteuereinheit einen Fahrsituationsparameter ermittelt, der den zumindest einen Parameter festlegt. Hierbei soll unter einem „Fahrsituationsparameter” insbesondere ein Parameter verstanden werden, der eine Fahrsituation, insbesondere eine generelle Fahrsituation, und/oder insbesondere eine allgemeine Kategorie für eine Fahrsituation für die aktuelle und/oder besonders vorteilhaft für die voraussichtliche Fahrtroute festlegt, wie beispielsweise eine Stadtfahrt, eine Überlandfahrt, eine Autobahnfahrt, eine Nachtfahrt usw.
