Abstract: A driver assistance system is provided for a motor vehicle, which has a first ascertainment device, the first ascertainment device implemented to ascertain at least one parameter that characterizes a possible fatigue of a current driver of the motor vehicle. In addition, the driver assistance system has a second ascertainment device, which is implemented to ascertain a degree of fatigue of the driver based on the at least one ascertained parameter. In addition, the driver assistance system has an opening device, which is implemented to at least partially open at least one window of the motor vehicle if the ascertained degree of fatigue of the driver exceeds a first predetermined threshold value.

Abstract: A method is provided for assessing the attentiveness of the driver of motor vehicle traveling in a lane including, but not limited to detecting the position of the motor vehicle on the lane transverse to the direction of travel, determining the extent of fluctuations of the position, and assessing the attentiveness as insufficient if within an observation period at least one first significant period is detected in which the extent of fluctuations of the position falls below a first low limiting value and a second significant period is detected in which the extent of the fluctuations exceeds a second high limiting value.

Abstract: A method is provided for operating a motor vehicle traveling on a roadway. The method includes, but is not limited to determining data of the roadway in the area, which includes determining a number n of lanes. If it is determined that n?2, it is determined whether a lane in which the vehicle is located with data of an optical camera of the motor vehicle. In addition, it is determined whether a second motor vehicle is traveling in the lane, in which the motor vehicle is located, in a direction of travel opposite a first direction of travel with a determination apparatus of the motor vehicle. If a second motor vehicle is determined, a warning message and/or automatic actuation is generated from an apparatus of the motor vehicle (e.g, a braking apparatus, a drive apparatus, or a steering apparatus).

Abstract: An output device with an output unit for issuing a warning notice is provided. The output device comprises a seat occupancy sensor which is connected with a control device for activating the output unit and which is designed, in case a safety belt on a rear seat comprising a foldable back rest has not been applied, to activate the output unit via the control device. The output device comprises a switch or button which is designed to block activation of the output unit by the control device, if the back rest is not in a sitting position.

Abstract: A method is provided for operating a motor vehicle. The method includes, but is not limited to determining whether the roadway in the area of the motor vehicle forms an approach to another roadway. If it is determined that the roadway forms an approach to another roadway, a first lane of the roadway in which the motor vehicle is located is determined with data of an optical camera of the motor vehicle. In addition, a direction of travel along in the first lane is determined and determined whether the motor vehicle is traveling in the direction opposite the direction of travel. If it is determined that the motor vehicle is traveling in the direction opposite the direction of travel, a first warning message is output and/or at least one apparatus (e.g., braking apparatus, a drive apparatus, and a steering apparatus) is actuated.

Abstract: A method is provided for the provision of information of a traffic sign. The method includes, but is not limited to sensing of a traffic sign by means of a determination device of a first vehicle takes place. The determination device includes, but is not limited to at least one optical camera. In addition, determination of information of the traffic sign by means of the determination device takes place. In addition, transmission of the determined information of the traffic sign to at least one second vehicle takes place.

Abstract: A method is provided for the adaption of a driving behavior of a vehicle with a change of driver. For this, driver-specific driving parameters, which characterize a driving style of a driver, of several vehicle drivers are stored as virtual driver profiles in the vehicle or in a drivers' control center. In addition, various methods are stored driver-specifically in the vehicle or in a drivers' control center, which respectively modify a reaction of the vehicle to driving parameters of a driver to the effect that a manner of driving, taking into account the limits of the vehicle, is ensured in traffic. During the driving of the vehicle, a first of the methods is then used and a comparison of stored virtual driver profiles with actually detected driver-specific driving parameters is carried out.
