Abstract
A method for synchronizing sensor data of a sensor system with the host time base of a host system, based on the clock ratio of the sensor time base to the host time base. To ascertain the clock ratio for at least two communication events, a time stamp acquisition is performed for each event, in which a sensor time stamp and a host time stamp is recorded. The communication events for ascertaining the clock ratio relate to a specific quantity of data. The ratio is ascertained/updated repeatedly; the duration of the individual communication events for the time stamp acquisition are measured; and by comparing each measured duration to a comparison value, possible irregularities in the communication event are detected. The host time stamp of a time stamp acquisition is corrected/replaced by a calculated host time stamp based on the measured irregularities. Also described is a related device for the method.
