ASAM MDF

Measurement Data Format (ASAM Standard)MDF (The process of recording data from internal ECU memory and external sensors.Measurement Data Format) is a binary Is a description about how information is encoded and structured and given a specific syntax for storage in a computer file.file format to store recorded or calculated data for post-The process of recording data from internal ECU memory and external sensors.measurement processing, off-line evaluation or long-term storage. The format has become a de-facto A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'.standard for The process of recording data from internal ECU memory and external sensors.measurement & The process of ECU parameter tuning. Tests with ECU hardware and software in the loop are carried out. ECU internal variables and external sensor data is recorded and analyzed. The values of internal ECU parameters are determined as a result of this process.calibration systems (Measurement and CalibrationMC-systems), but is also used in many other application areas.

As a compact binary format, ASAM Measurement Data Format (ASAM Standard)MDF offers efficient and high performance storage of huge amounts of The process of recording data from internal ECU memory and external sensors.measurement data. Measurement Data Format (ASAM Standard)MDF is organized in loosely coupled binary blocks for flexible and high performance writing and reading. Fast index-based access to each sample can be achieved by loss-free re-organization (i.e. sorting) of the data. Distributed data blocks even make it possible to directly write sorted Measurement Data Format (ASAM Standard)MDF files. The Is a description about how information is encoded and structured and given a specific syntax for storage in a computer file.file format allows storage of raw The process of recording data from internal ECU memory and external sensors.measurement values and corresponding conversion formulas; therefore raw data can still be interpreted correctly and evaluated by post-processing tools.

Since it became an ASAM A public specification, which has been developed by experts in a defined consensus-driven development process and was released by officials that represent a significant share of the industry for which it is targeted, giving the specification the necessary legitimacy to be called a 'Standard'.standard, Measurement Data Format (ASAM Standard)MDF has been developed in close alignment with other ASAM standards such as Measurement, Calibration and DiagnosticsMCD-2 Measurement and CalibrationMC (ASAP2) or Open Data Services (ASAM Standard)ODS. Consequently, ASAM Measurement Data Format (ASAM Standard)MDF supports special data types and information particularly required in the automotive area, e.g. structures and arrays (curves/maps), bus events and synchronized video data.

In addition to the plain The process of recording data from internal ECU memory and external sensors.measurement data and all necessary meta information for its interpretation, Measurement Data Format (ASAM Standard)MDF can also store descriptive and customizable supplementary data within the same file. ASAM Measurement Data Format (ASAM Standard)MDF offers flexible extensibility via generic Extensible Markup Language (W3C Standard)XML fragments and a range of new features like custom signal grouping, events or attachments.
