METHOD AND DEVICE FOR RECORDING EVENT DATA IN A VEHICLE: abstract simplified (18024580)

• This abstract for appeared for patent application number 18024580 Titled 'METHOD AND DEVICE FOR RECORDING EVENT DATA IN A VEHICLE'

Simplified Explanation

This abstract describes a method for recording event data in a vehicle. The method involves continuously receiving vehicle data from at least one vehicle system and writing it as event data in data frames of a specific size. These data frames are stored in a volatile memory. The stored data frames are managed and kept in the volatile memory until they become older than a predetermined maximum pre-event point in time. Alternatively, they can be stored persistently in a non-volatile memory if a specific event is recognized. The method also involves dividing the received reference information of the data frames into partitions of a specific size, and writing them in any time sequence. Subsequences of the written reference information in the partitions are randomly sorted and marked.

Original Abstract Submitted

A method for recording event data in a vehicle. Vehicle data are received continuously from at least one vehicle system and are written as event data in data frames of a predetermined 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 predetermined maximum pre-event point in time, or are stored persistently in at least one non-volatile memory in reaction to a recognized predetermined event. At least one partition of a predetermined size is provided, into which the received reference information of the individual data frames is written in any time sequence. Temporally randomly-sorted subsequences of the written reference information of the individual data frames in the at least one partition are ascertained and marked.
