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 (3, 7, 107); • 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 (3, 7, 107) is provided in the form of a time-of-flight 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 (3, 7, 107) or the detection element of the at least one sensor (3, 7, 107) 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 (3, 7, 107); • 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 (3, 7, 107) is provided in the form of a time-of-flight 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 (3, 7, 107) or the detection element of the at least one sensor (3, 7, 107) 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 (3, 7, 107) is provided in the form of a time-of-flight 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 (3, 7, 107) or the detection element of the at least one sensor (3, 7, 107) 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.
