1. A method for supporting at least one of an attentiveness or a driving readiness of a driver during an automated driving operation of a vehicle, the method comprising:
computing a failure probability value using a probability signal and a read-in map information signal and an environmental condition signal, the failure probability value representing a failure probability of a driver assistance system for carrying out an automated driving operation, the map information signal representing a road topography or confidence topography on a travel route that is traveled by the vehicle, and the environmental condition signal representing a weather condition in surroundings of the vehicle, wherein the probability signal represents an error probability or failure probability of at least one vehicle sensor of the driver assistance system;
determining a comparison parameter in response to the computed failure probability value, the comparison parameter representing a result of a comparison of an extent of a driving requirement on the traveled travel route of the vehicle to a degree of an instantaneous attentiveness of the driver;
providing an advance warning signal in response to the determined comparison parameter, the advance warning signal representing an advance warning for actively taking over a vehicle guidance by the driver of the vehicle; and
checking a driving behavior of the driver in response to the provided advance warning signal, using an attentiveness signal, at least one of the automated driving operation being switched off or a controlled transfer of the driving task to the driver being prompted when the driver ignores the advance warning for actively taking over a vehicle guidance.
