1. A method for automated driving in a vehicle, in which a driving system carries out one or more driving functions in automated fashion, the method comprising:
- operating the vehicle in an automated fashion using an automated driving function;
while the vehicle operates using the automated driving function, prompting a driver by the driving system;
after the prompting, ascertaining, by the driving system, a takeover time span based on an actuation of a device communicating with the vehicle by the driver, wherein the device is a mobile device that communicates with the vehicle wirelessly or via a connecting cable; and
only after expiration of the takeover time, terminating, by the driving system, the automated driving function;
wherein for ascertaining the takeover time span, different actuations of the device by the driver are assigned different actuation weighting factors, the actuation weighting factor assigned to the actuation of the device being taken into account in ascertaining the takeover time span.
