Summary:A method for recording event data in a vehicle. Vehicle data are continuously received from at least one vehicle system and written as event data into data frames having a predefined size. The individual data frames are stored in at least one volatile memory. The stored data frames are managed and kept available in the at least one volatile memory until the event data stored in the individual data frames are older than a predefined maximum pre-event point in time, or are persistently stored in at least one nonvolatile memory in response to a recognized predefined event. Multiple partitions having a predefined size are provided, one of the partitions being determined, as a function of at least one write criterion, as the present write partition into which the received pieces of reference information of the individual data frames are written.
