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.

Safety system

In a system having a control unit for triggering a restraint system for vehicles, and having a status acquisition device, such as a seat occupation device, from which a data record describing the presence or the non-presence of the condition is transmitted to the control device, upon a defined stimulation signal from the control unit to the status acquisition device the latter transmits a second data record to the control unit, which corresponds to the type characteristics and the type data. Thereby, type data are able to be recorded even in the case of a status acquisition device installed in an obstructed way in a motor vehicle.

An apparatus for protecting a vehicle occupant that triggers a restraint means as a function of the vehicle occupant's motion in the context of an accident. The motion is predicted in that by using an occupant detection system and an impact sensor system, a height of the center of mass of the vehicle occupant and a force action on the vehicle occupant are determined, and the motion of the vehicle occupant is thereby predicted.

A method and a system in the classification of objects occupying a seat, in particular for the reliable control of the triggering of restraint systems in motor vehicles. Utilized are the dynamics of a person seated on the seat, based on the acceleration forces acting on the person. Using the variables of these forces and the force exerted on the seat cushion of the seat by the mass of the person and its change, there is a determination, as a redundant variable, the mass, the location of the center mass and other physical variables and these are used for the reliable classification.

A device for classifying persons or objects, in particular for occupant classification in a motor vehicle, includes an arrangement for acquiring characteristic data on the person to be classified or the object to the classified; at least one algorithm for extracting features from the instantaneously acquired characteristic data; at least one filter for determining the classification of the person or the object from the instantaneously extracted features, taking into account the time progression of the features extracted for the person to be classified or the object to be classified; and a first counter for initiating the resetting of the filter when the algorithm, during the first time interval specified by the first counter, has exclusively provided features for the non-presence of a person or an object, so that the resetting behavior of the algorithm, or the filter downstream from the algorithm, may be decoupled from the output of the determined classification in a simple manner. A holding member is connected downstream from the filter to forward the classification determined by the filter, and a second counter is provided to initiate the resetting of the holding member if the algorithm, even after the second time interval specified by the second counter has elapsed, has provided only features for the non-presence of a person or an object.

Device for classifying persons or objects

A method for occupant classification in a vehicle is used to extract a plurality of features from a seat profile and to assign a weight estimate to each of these features. The occupant weight and a measure of quality are determined from the different weight estimates. The measure of quality determines whether the occupant weight continues to be used as the occupant classification. The weight estimation for the feature in question is carried out via a stored function. The occupant classification can be used for a restraint system. The ischial tuberosity distance and/or the seat profile size can be used as the features.

A distance sensor having a sensor for a motor vehicle in which an arrangement is provided by which gnment angles and trajectory curvatures can be compensated for during travel not only on a straight road but also along curves. In a sensor mounted displaced from the center line of the vehicle, an angle (alpha_sensor) is measured which cuts the projected center line of the motor vehicle at the target object, a vehicle driving ahead. By the additional use of a yaw rate sensor, curve curvatures of the road are also compensated for, so that angle and distance measurement can also be made along curves.
