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 (8a, 8b, 8c) for the motor vehicle on the basis of the surroundings information by means of the computer apparatus, wherein the identified driving manoeuvre or manoeuvres (8a, 8b, 8c) 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 (8a, 8b, 8c) 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 (8a, 8b, 8c) 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 (8a, 8b, 8c) for the motor vehicle on the basis of the surroundings information by means of the computer apparatus, wherein the identified driving manoeuvre or manoeuvres (8a, 8b, 8c) 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 (8a, 8b, 8c) 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.
