A method for influencing at least one driver assistance system of a motor vehicle , comprising the steps of: • receiving at least one signal value representing at least one attention characteristic of at least one motor vehicle occupant from at least one sensor ; • ascertaining , based on the signal value, at least one attention state of the motor vehicle occupant ; • determining whether the attention state of the motor vehicle occupant corresponds to a first attention state; and • in response to determining that the attention state corresponds to the first attention state, influencing the driver assistance system in a first manner, characterized in that at least one sensor is provided in the form of a time-of-flight (TOF) sensor , which is designed as a camera and has its own lighting unit in order to actively illuminate the region in front of the camera, and an additional lighting unit , which is designed to be separate from the at least one sensor or the detection element of the at least one sensor and is arranged at a distance therefrom, is provided for improved illumination of the depth region, and rotations of the body and head are identified and evaluated by a corresponding distance measurement of the TOF sensor , wherein the illumination of different regions in the interior of the motor vehicle being carried out such that the illumination is adapted to the state of the motor vehicle occupant . • receiving at least one signal value representing at least one attention characteristic of at least one motor vehicle occupant from at least one sensor ; • ascertaining , based on the signal value, at least one attention state of the motor vehicle occupant ; • determining whether the attention state of the motor vehicle occupant corresponds to a first attention state; and • in response to determining that the attention state corresponds to the first attention state, influencing the driver assistance system in a first manner, characterized in that at least one sensor is provided in the form of a time-of-flight (TOF) sensor , which is designed as a camera and has its own lighting unit in order to actively illuminate the region in front of the camera, and an additional lighting unit , which is designed to be separate from the at least one sensor or the detection element of the at least one sensor and is arranged at a distance therefrom, is provided for improved illumination of the depth region, and rotations of the body and head are identified and evaluated by a corresponding distance measurement of the TOF sensor , wherein the illumination of different regions in the interior of the motor vehicle being carried out such that the illumination is adapted to the state of the motor vehicle occupant . at least one sensor is provided in the form of a time-of-flight (TOF) sensor , which is designed as a camera and has its own lighting unit in order to actively illuminate the region in front of the camera, and an additional lighting unit , which is designed to be separate from the at least one sensor or the detection element of the at least one sensor and is arranged at a distance therefrom, is provided for improved illumination of the depth region, and rotations of the body and head are identified and evaluated by a corresponding distance measurement of the TOF sensor , wherein the illumination of different regions in the interior of the motor vehicle being carried out such that the illumination is adapted to the state of the motor vehicle occupant . <EOS>
