A method for operating a driver assistance system for motor vehicles, which each include multiple wheels in contact with a roadway, at least one of the motor vehicles ascertaining at least one instantaneous friction coefficient between at least one of the wheels and the roadway with the aid of at least one friction coefficient model, and at least one driver assistance unit of the respective motor vehicle being set or calibrated as a function of the ascertained friction coefficient. It is provided that the ascertained friction coefficient is transmitted to a central database, and that the database provides the ascertained friction coefficient to the other motor vehicles.

A method for operating a driver assistance system of a motor vehicle, which includes multiple wheels in contact with a roadway, the driver assistance system including at least one unit which includes a friction coefficient model and at least one sensor, which provides an input signal for the friction coefficient model, a friction coefficient between at least one of the wheels and the roadway being ascertained with the aid of the friction coefficient model, and the driver assistance system being set or calibrated as a function of the ascertained friction coefficient. Friction coefficients are ascertained with the aid of multiple of the units that ascertained friction coefficients are compared to one another, at least one valid friction coefficient of the friction coefficients is determined with the aid of the comparison, and the driver assistance system is set or calibrated as a function of the valid friction coefficient.

In a method for ascertaining a degree of attentiveness of a vehicle driver during travel with his vehicle, e.g., a motor vehicle, using a sensor of the vehicle, a direction of vision of the vehicle driver toward a region of a surrounding environment visible to the driver is recognized, and the region visible to the vehicle driver is assigned a probability distribution through which, on the basis of the recognized direction of vision of the vehicle driver, a degree of attentiveness of the vehicle driver is ascertained.

Method for ascertaining a degree of awareness of a vehicle operator

A method for operating a motor vehicle that has at least one driving engine which is operatively connected to at least one drive wheel and is controlled as a function of an accelerator-pedal position in order to generate a drive torque, an engine drag-torque control being carried out to avoid skidding of the drive wheel when the accelerator pedal is moved in the direction of a neutral position. It is provided that a maximum permissible engine drag torque is specified to the engine drag-torque control as a function of a currently effective coefficient of friction of the road surface which is determined as a function of a present position of the motor vehicle.

A method for warning other road users in response to a vehicle traveling in a wrong direction, the method including advance detection, setting-up, detection, and provision. In the step of advance detection, a potential of a possible instance of wrong-way travel of the vehicle is detected in advance. In the step of setting-up, a communication path to at least one road user endangered by the instance of wrong-way travel is set up, if the wrong-way travel potential is greater than an advance warning value. In the step of detection, the instance of wrong-way travel of the vehicle is detected. In the step of provision, an information item about the instance of wrong-way travel is provided for the endangered road user via the communication path set up, when the possible instance of wrong-way travel is detected as an actual instance of wrong-way travel.

A method for supplementing a piece of object information assigned to an object situated in surroundings of a vehicle includes: reading in a piece of sensor information; evaluating the sensor information; and expanding the object information. In the step of reading in, the piece of sensor information represents a response of a driver of the vehicle to an object situated in a viewing direction of the driver. In the step of evaluating, the sensor information is evaluated to obtain a piece of detection information representing whether the driver has detected the object. In the step of expanding, the object information is expanded with the piece of detection information.

A method for predicting an instant at which a predefined fatigue degree is expected to be reached in a vehicle system for fatigue detection, includes: (i) detecting the fatigue characteristic by continuously ascertaining the current fatigue degree of the vehicle operator; (ii) ascertaining a change in the fatigue degree over time within a predefinable time interval of the fatigue characteristic, and/or supplying an empirically determined change in fatigue degree over time; and (iii) ascertaining the instant at which a predefined fatigue degree is expected to be reached, based on the ascertained and/or supplied change in the fatigue degree.

A method to warn of a vehicle moving in the wrong direction of travel, wherein in a provision step, a third-party warning message is provided for other road users when at least one wrong-way-driver signal signals wrong-way travel of the wrongly moving vehicle sensed using a wrong-way-driver sensing method, and in an output step, a self-warning message is output for a driver of the vehicle moving in the wrong direction of travel when the wrong-way-driver signal signals the sensed wrong-way travel and at least one further wrong-way-driver signal signals the wrong-way travel of the wrongly moving vehicle sensed using a further wrong-way-driver sensing method, the further wrong-way-driver sensing method differing from the wrong-way-driver sensing method.
