A method and a device for specifying an operating strategy profile for the operation of a motor vehicle, and a method and a central database device for specifying a global geo-referenced operating strategy profile with regard to a driving route are provided. The following steps are executed: transmitting driving route data that characterize a scheduled driving route for an upcoming journey of the vehicle to a central database device; receiving operating strategy data from the central database device, which data characterize a proposed geo-referenced global operating strategy profile defined with respect to the driving route for the operation of the vehicle during its journey on the driving route; sensor-based acquisition of operating data that characterize an operating status and/or a driving situation of the vehicle during its journey on the driving route, and determining a local operating strategy profile for the operation of the vehicle during its continued journey on the driving route on the basis of the acquired operating data; specification of an operating strategy profile to be applied for the operation of the vehicle on the basis of the global operating strategy profile and the local operating strategy profile; and application of the specified operating strategy profile for the operation of the vehicle on the driving route.

Method and devices for specifying an operating strategy profile

A control unit for operating a motor vehicle includes a basic module and a function module, which is constructed in a secured run-time environment. The control unit includes predefined first and second interfaces, which each couple the basic module and the function module. The basic module is designed for determining one or more function input quantities, depending on at least one operating quantity, and for providing the function input quantities at the first interface. The basic module is further designed for determining control variables of the actuators, depending on one or more output quantities, which are provided at the second interface. The function module is designed for determining the one or more output quantities, depending on the function input quantities provided t the first interface and a predefined quantity of rules, which output quantities characterize an operating strategy from a quantity of predefined operating strategies, and for providing the output quantities at the second interface.
