Patent ID: 7856880

Claim:
A vehicle sensor ( 4 ) for detecting impact sound, the sensor comprising: a measured-value sensor ( 4 . 1 ) for detecting the impact sound; and multiple individual, separate measured-value sensing elements ( 4 . 1 .x), each of which is coupled to a vehicle structure ( 5 ) in such a way that impact sound waves are transmitted by the vehicle structure ( 5 ) to the measured-value sensing elements ( 4 . 1 .x), wherein the measured-value sensing elements ( 4 . 1 .x) are coupled to the vehicle structure ( 5 ) by an elastic ( 7 . 1 ) or a visco-elastic ( 7 . 2 ) coupling layer for transmitting the impact sound waves wherein a matrix is arranged between the measured-value sensing elements ( 4 . 1 .x) and the vehicle structure ( 5 ), the matrix having recesses between the measured-value sensing elements ( 4 . 1 .x) and the vehicle structure ( 5 ), and the visco-elastic coupling layer ( 7 . 2 ) is embodied in form of fillings ( 7 . 2 . 3 ) of the recesses.
