摘要:
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 method and a device are for evaluating sensor signals from a seat mat in a vehicle seat, the signals functioning to characterize the sensors in the seat mat as active and inactive. In this manner, a linear evaluation method is performed to make possible a weight classification of passengers situated on the vehicle seat. For this purpose, a seat profile is generated using the active and inactive sensors.
摘要:
A method for adjusting the sensor cells of a seat mat to a mechanical stress caused by the installation of the seat mat in a vehicle seat, a diagnostic tester being connected to a control unit at the seat mat, and the diagnostic tester reads out the sensor values of the seat mat and compares them to setpoint values, in order then to transmit back correcting values to the control unit, which the control unit uses in further operation for calibrating the sensor values.
摘要:
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.

In a method for deactivating a safety function in a motor vehicle after being activated, the safety function may be deactivated by the driver only after a dead time has elapsed.
摘要:
A safety system for a vehicle having at least one safety device, which records and/or ascertains and evaluates one or a plurality of variable(s) regarding driving dynamics to activate at least one protection device. In response to user-dependent inputs, a parameterization device specifies settings and/or applications and/or parameters for the safety device in order to influence the trigger behavior of the at least one protection device.
摘要:
A method for plausibilizing sensor signals of a vehicle system, the sensor signals being monitored with regard to compliance with one plausibility criterion or a plurality of plausibility criteria with the aid of a plausibilization algorithm. The function of the vehicle system is able to be maintained even in critical driving situations, in particular following a collision, if the driving status of the vehicle is monitored with regard to a collision and the plausibilization algorithm is modified if a collision was detected.
摘要:
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 device for classifying the seat occupancy in a motor vehicle by which the accuracy in the detection of child seats may be increased is provided. The seats of the motor vehicle are each equipped with a safety belt, a belt buckle for the safety belt and a belt-buckle switch. The device includes at least one belt-force sensor for at least one safety belt. According to the present invention, the belt-force sensor and the belt-buckle switch assigned to the respective safety belt are interconnected in such a way that the output signals of the belt-force sensor and the belt-buckle switch are combined into one belt-buckle output signal.
