Abstract

A method for processing sensor data which are transmitted by at least one asynchronous sensor at a transfer rate into a buffer memory, the sensor data being read from the buffer memory at a predefined sampling rate, and a mean value being computed from a predefined number of read sensor data. The transfer rate to sampling rate ratio is selected in such a way that the number of sensor data averaged within a sampling period is n or (n+1), the mean values of the read sensor data being computed using a fixed synchronized phase shift with respect to the sampling rate, which is determined in averaging (n+1) sensor data, n being a natural number greater than or equal to two.
