Method for operating a driver assistance device of a motor vehicle , having the method steps: a) sensing a surrounding area of the motor vehicle by means of a surroundings sensor apparatus of the driver assistance device ; b) providing surroundings information which represents the sensed surroundings , to a computer apparatus of the driver assistance device ; c) identifying one or more possible driving manoeuvres for the motor vehicle on the basis of the surroundings information by means of the computer apparatus , wherein the identified driving manoeuvre or manoeuvres is/are selected from a group of driving manoeuvres which comprises a lane-given manoeuvre and/or an overtaking manoeuvre and/or a lane-changing manoeuvre and/or an avoidance manoeuvre; d) sensing a behaviour of a driver of the motor vehicle by means of a vehicle-internal sensor apparatus ; e) providing behaviour information which represents the behaviour of the driver , to the computer apparatus ; f) detecting whether one of the identified driving manoeuvres is a driving manoeuvre which is intended by the driver , on the basis of the provided behaviour information, by means of the computer apparatus ; characterized in that if an identified driving manoeuvre is an intended driving manoeuvre : g) calculating a setpoint trajectory of the motor vehicle for the intended driving manoeuvre by means of the computer apparatus ; h) registering a steering input of the driver and checking whether the steering input has to be boosted or attenuated in order to guide the motor vehicle along the setpoint trajectory ; i) boosting or attenuating the steering input in accordance with a result of the checking process, wherein for a calculated setpoint trajectory the registration according to method step h) and the boosting or attenuation according to method step i) are carried out continuously. a) sensing a surrounding area of the motor vehicle by means of a surroundings sensor apparatus of the driver assistance device ; b) providing surroundings information which represents the sensed surroundings , to a computer apparatus of the driver assistance device ; c) identifying one or more possible driving manoeuvres for the motor vehicle on the basis of the surroundings information by means of the computer apparatus , wherein the identified driving manoeuvre or manoeuvres is/are selected from a group of driving manoeuvres which comprises a lane-given manoeuvre and/or an overtaking manoeuvre and/or a lane-changing manoeuvre and/or an avoidance manoeuvre; d) sensing a behaviour of a driver of the motor vehicle by means of a vehicle-internal sensor apparatus ; e) providing behaviour information which represents the behaviour of the driver , to the computer apparatus ; f) detecting whether one of the identified driving manoeuvres is a driving manoeuvre which is intended by the driver , on the basis of the provided behaviour information, by means of the computer apparatus ; g) calculating a setpoint trajectory of the motor vehicle for the intended driving manoeuvre by means of the computer apparatus ; h) registering a steering input of the driver and checking whether the steering input has to be boosted or attenuated in order to guide the motor vehicle along the setpoint trajectory ; i) boosting or attenuating the steering input in accordance with a result of the checking process, wherein for a calculated setpoint trajectory the registration according to method step h) and the boosting or attenuation according to method step i) are carried out continuously. <EOS>
