Abstract
A method for operating a vehicle includes: specifying a time-related target power demand for the vehicle to an internal combustion engine; and switching in an additional powering device in addition to the internal combustion engine when a time-related actual power demand of the vehicle on the internal combustion engine deviates from the time-related target power demand. The present invention makes it possible to operate the internal combustion engine in a diagnosis mode largely independently of the specific driving situation.

13. A method for operating a vehicle, comprising:
-
specifying a time-related target power demand for the vehicle to an internal combustion engine powering the vehicle, the time-related target power demand being dependent on a vehicle diagnosis to be carried out on the internal combustion engine; switching in an additional powering device for the vehicle in addition to the internal combustion engine when a time-related actual power demand of the vehicle on the internal combustion engine deviates from the time-related target power demand; estimating the time-related actual power demand of the internal combustion engine on a route to be driven with the vehicle; scheduling the vehicle diagnosis to be carried out based on a probability that a difference between the time-related actual power demand and the time-related target power demand can be compensated for by switching in the additional powering device in addition to the internal combustion engine; and prohibiting vehicle diagnosis when the probability falls below a predetermined threshold value. - View Dependent Claims (14, 15, 16, 17)

18. A control apparatus for operating a vehicle, comprising:
a control unit including a processor configured to perform the following; specifying a time-related target power demand for the vehicle to an internal combustion engine powering the vehicle, the time-related target power demand being dependent on a vehicle diagnosis to be carried out on the internal combustion engine; switching in an additional powering device for the vehicle in addition to the internal combustion engine when a time-related actual power demand of the vehicle on the internal combustion engine deviates from the time-related target power demand; estimating the time-related actual power demand of the internal combustion engine on a route to be driven with the vehicle; scheduling the vehicle diagnosis to be carried out based on a probability that a difference between the time-related actual power demand and the time-related target power demand can be compensated for by switching in the additional powering device in addition to the internal combustion engine; and prohibiting vehicle diagnosis when the probability falls below a predetermined threshold value.

19. A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for operating a vehicle, the method comprising:
-
specifying a time-related target power demand for the vehicle to an internal combustion engine powering the vehicle, the time-related target power demand being dependent on a vehicle diagnosis to be carried out on the internal combustion engine; switching in an additional powering device for the vehicle in addition to the internal combustion engine when a time-related actual power demand of the vehicle on the internal combustion engine deviates from the time-related target power demand; estimating the time-related actual power demand of the internal combustion engine on a route to be driven with the vehicle; scheduling the vehicle diagnosis to be carried out based on a probability that a difference between the time-related actual power demand and the time-related target power demand can be compensated for by switching in the additional powering device in addition to the internal combustion engine; and prohibiting vehicle diagnosis when the probability falls below a predetermined threshold value.
