| 20110071733 | DEVICE FOR DETECTING THE CHARACTERISTICS OF AN IMPACT INTO A MOTOR VEHICLE - A device for the detection of the characteristics of an impact into a motor vehicle includes at least one signal generating unit for generating a defined acoustic impulse sequence depending on the speed of the impact, particularly a structure-borne acoustic impulse sequence due to a deformation of a chassis component of the motor vehicle. The acoustic impulse sequence is generated by way of a mechanical activation of the signal generating device caused by the deformation. A sensor system is disposed to detect the defined acoustic impulse sequence. An analysis unit analyses the signals supplied by the sensor system such that information can be supplied on the characteristics of the impact. | 03-24-2011 |
