摘要:
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.

In the case of an electronic apparatus (1), a protective circuit (10) for positive and negative voltage spikes is provided, which circuit includes two diodes (12, 13). The first diode (12), polarized in the forward direction, is arranged in the positive branch of the voltage supply. The second diode (13), polarized in the reverse direction, is connected, on the one hand, to the cathode connection of the first diode (12) and, on the other hand, to the ground connection.

A control unit in a vehicle is provided in which power is supplied via a converter that provides an electrical isolation. For the data exchange with external components and other components in the control unit that are not electrically isolated, the component isolated by this electrical isolation is additionally connected to a coupling element that likewise provides an electrical isolation.

In an electronic device, in particular a piece of safety equipment for vehicle occupants, a switching element (13) which characterizes the operational position of an insertable seat belt is connected in parallel with a firing element (10, 11). The switching element (13) has a break contact which is broken when the seat belt is activated correctly.

Proposed is a method for programming and/or testing for the correct functioning of an electronic circuit, and a corresponding device, which is used to efficiently program and test electronic circuits combined on a wafer, prior to their separation. For this purpose, a bus allowing the individual electronic circuits to be sequentially tested is positioned on the wafer. Each electronic circuit is assigned an address for the bus, using a hardware code. The address is deactivated after completion of the functionality and testing method.
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.
摘要:
A method for measuring the resistance of a load, preferably the firing pellet of an airbag, that is connected on the secondary side of a rotary transformer, in which the resistance measurement is largely unaffected by the magnetic coupling between the windings of the transformer. According to this method, the capacitor is partially discharged twice in succession. During the first partial discharge, the capacitor is discharged continuously, and during the second partial discharge, the capacitor is discharged in steps. After the two partial discharges, the residual charge voltages at the capacitor are measured and the difference between the two charge voltages is obtained. This difference is an indication of the resistance of the load connected on the secondary side of the transformer.
摘要:
A method for triggering at least one passenger protection means. The method includes a step of reading in a control signal which contains a command for carrying out an activation of the passenger protection means. Furthermore, method includes a step of releasing an activation of the passenger protection means as a response to the read-in control signal. Furthermore, the method includes a step of evaluating the control signal for the identification of the command for carrying out the activation of the passenger protection means and activating the passenger protection means as a response to an identified command for carrying out the activation of the passenger protection means to trigger the passenger protection means.
