The present disclosure relates to a method for determining the fatigue of a driver of a motor vehicle, wherein the fatigue is determined while taking into account the steering behavior of the driver, characterized in that the method includes the following steps: determination of a hysteresis of the steering system or the fatigue detection system, and taking into account the detected hysteresis in the determination of the fatigue of the driver. Furthermore, the disclosure relates to a device that is set up to execute the method.

Method for determining the fatigue of a driver and appropriate device

A method for detecting drowsiness of a driver for a driver assistance system of a vehicle includes reading in at least a first indicator signal that represents a first drowsiness parameter of the driver determined by a first drowsiness-detection device of the vehicle, and a second indicator signal that represents a second drowsiness parameter of the driver determined by a second drowsiness-detection device of the vehicle, and optionally a third indicator signal that represents a third drowsiness parameter of the driver determined by a third drowsiness-detection device of the vehicle; ascertaining validities of the indicator signals; and determining a drowsiness signal that represents the detected drowsiness of the driver utilizing the indicator signals and the validities.

Method and control unit for detecting drowsiness of a driver for a driver assistance system for a vehicle

A method for stopping an internal combustion engine, in which an air flow supplied via an air metering device, in particular a throttle valve of the internal combustion engine, is reduced after a stopping request has been ascertained, an undershoot point in time is ascertained, at which an ascertained speed of the internal combustion engine falls below a pre-definable speed threshold value, after the undershoot point in time, the air flow supplied via the air metering device of the internal combustion engine is increased again, the predefinable speed threshold value being selected in such a way that an intake cylinder no longer enters a compression stroke after the increase of the supplied air flow until the internal combustion engine is at a standstill, a degree of opening of the air metering device to increase the supplied air flow being selected as a function of a coasting speed of the internal combustion engine.
