1. A method to operate a motor vehicle using a driver assistance system, comprising:
- defining, for at least one driver assistance system function, at least one criterion relating to a vehicle environment to adapt the driver assistance system function, wherein the at least one driver assistance system function includes a traffic jam assistance function, a highway assistance function, an ACC stop-and-go function, an active high beam assistance function, and a hands-off driving assistance function;
detecting features of the vehicle environment;
estimating a probability of occurrence of at least one criterion responsive to a combination of the features;
adapting the driver assistance system function based on the probability of occurrence of the at least one criterion, wherein the driver assistance system function is further configured to control the hands-off driving assistance function to be unavailable for one of a specified time and specified distance in response to the probability of occurrence of the at least one criterion; and
indicating to a driver a warning signal that informs the driver of an end of availability of the hands-off driving function, and modifying a time between the warning signal and a further warning signal based on the estimated probability.

Abstract
A method is disclosed to operate a motor vehicle using a driver assistance system. The driver assistance system includes, for at least one driver assistance system function, at least one criterion relating to a vehicle environment. The at least one criterion is defined for an adaptation of the driver assistance system function, a number of features of the environment of the vehicle are detected, a probability of the occurrence of at least one criterion is estimated on the basis of a combination of the detected features, and the driver assistance system function is adapted on the basis of the estimated probability.

11. A device that adapts at least one driver assistance system function of a motor vehicle comprising:
-
a control unit configured to, according to defined criteria relating to a vehicle environment for at least one driver assistance system function from a driver assistance system and in response to detected environment features of the vehicle environment, adapt the driver assistance system based on an estimate of an occurrence probability of criteria from a combination of the environment features, indicate to a driver a warning signal that informs the driver of an end of availability of a hands-off driving assistance function, and modify a time between the warning signal and a further warning signal based on the estimated probability; wherein the at least one driver assistance system function includes a traffic jam assistance function, a highway assistance function, an ACC stop-and-go function, an active high beam assistance function, and the hands-off driving assistance function; and wherein the driver assistance system function is further configured to control the hands-off driving assistance function to be unavailable for one of a specified time and specified distance in response to the occurrence probability of criteria. - View Dependent Claims (12, 13, 14)

15. A vehicle comprising:
-
a driver assistance system that controls a vehicle trajectory, the driver assistance system having at least one driver assistance system function, the at least one driver assistance system function including a traffic jam assistance function, a highway assistance function, an ACC stop-and-go function, an active high beam assistance function, and a hands-off driving assistance function; a plurality of sensors configured to detect features of a vehicle environment; and a control unit configured to, in response to defined criteria relating to the vehicle environment, for the driver assistance system and detected features of the vehicle environment, adapt the driver assistance system based on an estimate of an occurrence probability of criteria from a combination of the detected environment features to control the vehicle along the trajectory, indicate to a driver a warning signal that informs the driver of an end of availability of the hands-off driving function, and modify a time between the warning signal and a further warning signal based on the estimate of the occurrence probability; wherein the driver assistance system function is further configured to control the hands-off driving assistance function to be unavailable for one of a specified time and specified distance in response to the occurrence probability of criteria. - View Dependent Claims (16, 17)
