Abstract: The switched state of a pressure switch in a tank ventilation system of a motor vehicle is used for testing the function of the tank ventilation system, the pressure switch being in a low-pressure position if the pressure in the tank ventilation system is lower than a predefined pressure limit while being in a high-pressure position if that is not the case. A defective pressure switch can result in wrong assessments. Disclosed is a method for testing the function of the pressure switch, the method encompassing the following steps: a switched state of the pressure switch is detected; a measure is carried out that increases the pressure in the tank ventilation system above the pressure limit if the pressure switch is in the low-pressure position; a defect of the pressure switch is identified if the pressure switch remains in the low-pressure position after carrying out the measure.

Abstract: A safety system for vehicle occupants having a device for determining the position of the vehicle occupant. A status monitor to which the output signals of sensors are conveyed is provided for determining the position of the vehicle occupant, the sensors detecting the acceleration of the vehicle and the weight of the vehicle occupant. A method for controlling a safety system.

Abstract: In a method for activating occupant protection means as a function of at least one input quantity derived from at least one acceleration sensor, characteristic curves are calculated for the input quantities deceleration, forward displacement and/or speed reduction, which characteristic curves define at least one area in a quadrant of a coordinate system, which determines the deployment behavior of the occupant protection means.
