Beschreibung
Zusammenfassung:	A method of early recognition of damage in a motor vehicle transmission which comprises at least one acceleration sensor, with which mechanical vibrations in the motor vehicle transmission are detected and converted into an electrical signal. The electrical signal is then digitalized and thereafter carrying our a comparison with a comparison parameter. The mechanical vibrations are detected at defined operating points of the motor vehicle transmission and, from the digitalized electrical signal acceleration amplitudes, are determined over a time interval. A count is taken of conditions in which the acceleration amplitudes exceed the comparison parameter and, with reference to the number of such conditions, a calculated probability of damage in the motor vehicle transmission is determined. A motor vehicle transmission whose damage can be determined by the method, and a computer program product for carrying out the individual process steps are also proposed.
