An example method for data parameter reasonability analysis includes receiving a source data file including a plurality of data frames having formats that are unknown, and a data frame includes a data word layout having data words concatenated together and the data words are representative of outputs from a plurality of sensors, comparing the sensor data to compatible parameter values for a type of sensor mapped to the location of the sensor data in the data word layout as for available data frame formats, generating a difference map illustrating one or more data words having sensor data incompatible with the type of sensor mapped to the location of the sensor data in the data word layout, assigning a data frame format to the plurality of data frames, determining reasonableness of the sensor data in the source data file, and providing a report as to reasonability of the sensor data.

An on-board recording system for a vehicle is disclosed. The on-board recording system is configured to monitor data for errors. The on-board recording system includes one or more processors and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the processors, causes the on-board recording system to receive as input a data sequence including a plurality of frames. The frames are received and recorded by the on-board recorder at a corresponding assigned time offset and include a corresponding assigned message. The on-board recording system is further caused to determine a missing assigned message that has not been received at the corresponding assigned time offset. In response to determining the missing assigned message, the on-board recording system calculates a total length of time based on a number of missing assigned messages stored in the memory.

A system and method for processing source data, which includes a translation processor configured on a server to translate a stream of source data received at the server into a stream of formatted data types based on one or more of parameter definitions for the source data and new parameter information for the source data having an unknown data type. The source data can be received at the server from multiple sources and the data format may not be consistent from one source to another. An analytics processor on the server can be configured to operate on the out-of-tolerance data type to perform one or more of trend data analytics, associated data analytics and preventative action analytics.
