Method for classifying a non-driving activity of a driver with regard to interruptibility of the non-driving activity in the event of a request to take over the driving task during automated and/or highly automated driving, wherein the method has the following steps of: reading in a detection signal and a first position signal from a vehicle occupant monitoring device of a vehicle, wherein the detection signal represents a detected object which serves a non-driving activity of the driver, and wherein the first position signal represents a first position of the detected object; receiving a take-over request signal, wherein the take-over request signal represents a request for the driver to take over the driving task; in response to the receiving step, ascertaining a second position of the detected object using a second position signal, wherein the second position signal represents a final position of the object and defines an area of interest before the driver takes over the driving task and interrupts the non-driving activity, and wherein the non-driving activity of the driver is classified using the positions (225, 230) of the object and/or determined viewing and/or head directions of the driver in the area of interest; and after the ascertaining step, determining a level of interruptibility with regard to interruptibility of the non-driving activity, wherein the level of interruptibility is determined using a mathematical model, wherein the level of interruptibility represents a degree of visual and/or cognitive appropriation of the driver by the non-driving activity, characterized in that a step of calculating a probability of the driver being distracted by the classified non-driving activity is provided, wherein the probability is calculated using a previous probability based on the determined level of interruptibility of the non-driving activity before the driver took over the driving task and an analysis of the viewing and/or head direction of the driver after the driver has taken over the driving task. reading in a detection signal and a first position signal from a vehicle occupant monitoring device of a vehicle, wherein the detection signal represents a detected object which serves a non-driving activity of the driver, and wherein the first position signal represents a first position of the detected object; receiving a take-over request signal, wherein the take-over request signal represents a request for the driver to take over the driving task; in response to the receiving step, ascertaining a second position of the detected object using a second position signal, wherein the second position signal represents a final position of the object and defines an area of interest before the driver takes over the driving task and interrupts the non-driving activity, and wherein the non-driving activity of the driver is classified using the positions (225, 230) of the object and/or determined viewing and/or head directions of the driver in the area of interest; and after the ascertaining step, determining a level of interruptibility with regard to interruptibility of the non-driving activity, wherein the level of interruptibility is determined using a mathematical model, wherein the level of interruptibility represents a degree of visual and/or cognitive appropriation of the driver by the non-driving activity, characterized in that a step of calculating a probability of the driver being distracted by the classified non-driving activity is provided, wherein the probability is calculated using a previous probability based on the determined level of interruptibility of the non-driving activity before the driver took over the driving task and an analysis of the viewing and/or head direction of the driver after the driver has taken over the driving task.
