Claim of US Patent No. 9,321,454

1. 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.
