ASAM Calibration Data Format (ASAM Standard)CDF defines the data description format for storing the ECU parameter values and the associated meta data. The ECU parameter values adapt the control algorithms in automotive ECUs to achieve required or optimal control results. The values of parameters are typically determined through an iterative 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 process.
ECU parameter values are developed over time from different tests, for different software versions of the ECU and for different hardware versions of the controlled system. Variations in the hardware configuration of the controlled system may require variants of the parameter values. Engineers and their management need all of this information and additional quality information about parameters to be able to decide on further development steps.
ASAM Calibration Data Format (ASAM Standard)CDF provides a Is a description about how information is encoded and structured and given a specific syntax for storage in a computer file.file format that defines and stores this information in a machine-readable format. Specifically, ASAM Calibration Data Format (ASAM Standard)CDF allows the storing of A real number.scalar values, strings, arrays, curves, maps, structures and arrays of supported data types. The description contains quality and process-related meta information for each parameter value. The 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 supports typical 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 process steps from their default state to production-readiness. Values are stored in their physical format together with a unit, which allows the Calibration Data Format (ASAM Standard)CDF file to be directly read and understood by engineers.

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 data management tools (CDM tools). The format allows easy import and export, comparison and merge of data from various sources. ASAM Calibration Data Format (ASAM Standard)CDF is a complementary 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 to ASAM Measurement, Calibration and DiagnosticsMCD-2 Measurement and CalibrationMC and ASAM Model Data Exchange Format (ASAM Standard)MDX, which describe the properties of the parameters. ASAM Calibration Data Format (ASAM Standard)CDF is used in parallel to ASAM Measurement Data Format (ASAM Standard)MDF, which stores measured values. Provided that the 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 tool chain is compliant to these standards, data exchanges are seamless, do not require format-conversions and are independent from specific tool vendors.
ASAM Calibration Data Format (ASAM Standard)CDF files uses Extensible Markup Language (W3C Standard)XML, which can be easily validated, edited, imported and exported by 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 tools and Extensible Markup Language (W3C Standard)XML-editors. The format is technology- and vendor-independent. Due to its completeness, versatility and maturity, the 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 is widely used and supported by virtually all major Measurement and CalibrationMC-systems on the market today.
