Claim:
1. A method for monitoring a driver of a vehicle, the method comprising the acts of: receiving a state of the driver; receiving one or more objects of a real environment model of the vehicle; generating one or more objects of an envisioned environment model of the driver based on the one or more objects of the real environment model of the vehicle and the state of the driver, wherein, if the state of the driver indicates that at least one sense of the driver sensed a particular object of the real environment model, the particular object of the real environment model is added to the envisioned environment model; updating the one or more objects of the envisioned environment model based on the state of the driver, wherein the one or more objects of the envisioned environment model are updated by a physics engine if the state of the driver indicates that the driver is prevented from sensing the one or more objects of the real environment model; computing a deviation factor between the particular object of the real environment model and the corresponding object of the envisioned environment model; calculating a situation awareness factor based on the deviation factor for the particular object of the real environment model and the corresponding object of the envisioned environment model; and calculating a take-over ability time based on a function of the situation awareness factor.
