20090219149 | Method and device for crash type identification for a vehicle - A method for crash type identification for a vehicle in which sensor data from the left vehicle side and from the right vehicle side are recorded and analyzed via at least two sensor units, as well as an associated device for crash type identification for a vehicle. The sensor data, recorded after an impact, are gated, at least one first gating of the recorded sensor data being checked for fulfillment of a stability criterion and, after meeting the stability criterion, at least one second gating of the recorded sensor data is compared with a predefined threshold value, a first criterion for an asymmetrical impact flag signal being recognized when the second gating of the recorded sensor data exceeds the predefined threshold value and/or falls short of the predefined threshold value. | 09-03-2009 |
20100231401 | CONTROL DEVICE AND METHOD FOR TRIGGERING PASSENGER PROTECTION DEVICES - A method and a control device for triggering passenger protection devices are provided, the passenger protection devices being triggered as a function of a first acceleration signal and/or a driving dynamics signal.

20110218710 | METHOD AND CONTROL DEVICE FOR TRIGGERING PASSENGER PROTECTION MEANS FOR A VEHICLE - In a method for triggering a passenger protection arrangement for a vehicle, a crash type is detected with the aid of at least one structure-borne noise signal, and the triggering takes place as a function of the crash type. For the crash type recognition, the structure-borne noise signal is evaluated in a predefined time period with regard to a change in amplitude. | 09-08-2011 |
20120265406 | METHOD AND CONTROL UNIT FOR DETECTING A SAFETY-CRITICAL IMPACT OF AN OBJECT ON A VEHICLE - A method for detecting a safety-critical impact of an object on a vehicle is described. The method has a first step of obtaining a starting signal for starting a time measurement, to establish the start of a subsequent predetermined time span. In addition, the method has a step of receiving a signal representing a yaw acceleration of the vehicle, the signal being received during the predetermined time span. Finally, the method has a step of detecting the safety-critical impact of the object on the vehicle detecting the safety-critical impact of an object on the vehicle when the signal within the predetermined time span has a value that is outside a threshold value range or when the signal after the predetermined time span has a value derived from the signal that is outside of a threshold value range. | 10-18-2012 |
20120310485 | METHOD AND CONTROL UNIT FOR ASCERTAINING A TYPE OF COLLISION OF A VEHICLE - A method for ascertaining a type of collision of a vehicle includes: receiving acceleration information items, via a reception interface, representing the accelerations of the vehicle in a vehicle longitudinal direction and a vehicle transverse direction; determining a first resultant acceleration information item from a first and a second acceleration information item; determining a second resultant acceleration information item from a third and a fourth acceleration information item; combining the first and second resultant acceleration information items to obtain at least one evaluation information item; and determining the collision type based on the at least one evaluation information item. | 12-06-2012 |
20130090814 | METHOD AND DEVICE FOR THE DETERMINATION OF AT LEAST ONE TRIGGERING PARAMETER OF PERSONAL PROTECTION MEANS OF A VEHICLE - A method to determine at least one triggering parameter of personal protection device of a vehicle using pattern signal curves of a possible signal of a sensor for a physical variable. The pattern signal curves replicating a curve over time of the physical variable upon impact of an object on the vehicle at a different location on the vehicle and/or upon impact of the object on the vehicle at a different angle. A sensor signal is read which represents the physical variable measured by a sensor. Values of a curve over time of the sensor signal are compared to values of the at least two pattern signal curves, that pattern signal curve being selected which, in at least one time segment of the pattern signal curve or one scaled form of the pattern signal curve has a lower deviation from the curve over time of the sensor signal. | 04-11-2013 |
20150224951 | Method and device for triggering at least one passenger protection means of a vehicle - A method for triggering a passenger protection unit of a vehicle includes: reading in a first and a second sensor signal value of a first sensor, which is situated at a first location in the vehicle; reading in a third and a fourth sensor signal value of a second sensor, which is situated at a second location in the vehicle which is different from the first location; and activating the passenger protection unit using the first, second, third and fourth sensor signal values. The first and third sensor signal values represent a physical variable detected in a first sensor direction, and the second and fourth sensor signal values represent a second physical value detected in a second sensor direction which is different from the first sensor direction. | 08-13-2015 |
20150314744 | METHOD AND DEVICE FOR ACTIVATING A PEDESTRIAN PROTECTION MEANS FOR A VEHICLE, AND RESTRAINT SYSTEM FOR A VEHICLE - A method is provided for activating a pedestrian protection system of a vehicle. The method includes a step of carrying out a first threshold value comparison, in the first threshold value comparison at least one signal feature of a first sensor signal being compared to an adaptation threshold value, a step of determining a threshold value adaptation value based on a result of the first threshold value comparison, and a step of carrying out a second threshold value comparison. In the second threshold value comparison, at least one signal feature of a second sensor signal is compared to a triggering threshold value, which is adapted using the threshold value adaptation value, for triggering the pedestrian protection system. | 11-05-2015 |
