ASAM MCD-3 MC

One of the major tasks of ECU development is 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 and test of control strategies, i.e. tuning of parameters and the recording of internal variables during the runtime of the ECU. These tasks can be done via various busses, bus protocols or proprietary plug-on devices between the ECU and 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 system. Those interfaces are technology-dependent and vendor-specific. In order to provide uniform access to an ECU, 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 typically have an Measurement and CalibrationMC-server that other tools can use to connect to an ECU without having to deal with different interface technologies. The main objective of the ASAM Measurement, Calibration and DiagnosticsMCD-3 Measurement and CalibrationMC 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 to specify the functions of an Measurement and CalibrationMC-server and to provide a remote control interface for client applications to the Measurement and CalibrationMC-server via an object-oriented Application Programming InterfaceAPI. The functions of an Measurement and CalibrationMC-server are primarily to provide The process of recording data from internal ECU memory and external sensors.measurement and 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 services to clients. 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 allows that any client application, such as test automation systems or automated 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, can connect via the Measurement and CalibrationMC-server to an ECU and carry out typical The process of recording data from internal ECU memory and external sensors.measurement and 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 tasks. Several client applications can be connected to one Measurement and CalibrationMC-server and have access to one ECU in parallel. 

To be able to access data on an ECU, the Measurement and CalibrationMC-server reads an ASAM MCD-2 MC LanguageA2L data description file (according to ASAM Measurement, Calibration and DiagnosticsMCD-2 Measurement and CalibrationMC), which contains a description of available 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 parameters (CHARACTERISTICS) and The process of recording data from internal ECU memory and external sensors.measurement variables (MEASUREMENTS).  The Measurement and CalibrationMC-server then makes services available to access this data. Methods for read- and write-access to 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 parameters of various types such as scalars, arrays, strings and look-up tables can be used. The process of recording data from internal ECU memory and external sensors.Measurement access methods are available via Collector, Watcher and Recorder services. The Collector acquires the values of The process of recording data from internal ECU memory and external sensors.measurement variables or 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 parameters with a common rate over a defined period of time (continuous data acquisition) and sends the data to the client applications at the same time. The Recorder is used to manage high bandwidth measurements, when synchronous data transfer to the client is not possible. The Recorder stores the data locally and makes it available to clients at a later time. A Watcher is a service which continuously monitors The process of recording data from internal ECU memory and external sensors.measurement variables or 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 parameters and triggers events if a predefined condition is met. Multiple Watchers can be defined to monitor multiple objects at the same time. The Watcher may be used to start and stop Collectors or Recorders.

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 used for 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 and The process of recording data from internal ECU memory and external sensors.measurement purposes in development, testing and production of ECUs. ASAM Measurement, Calibration and DiagnosticsMCD-3 Measurement and CalibrationMC currently coexists with the older ASAM ASAP3 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, which is dependent on specific interfaces (RS232, Ethernet) and is still widely used. The ASAM Measurement, Calibration and DiagnosticsMCD-3 Measurement and CalibrationMC Application Programming InterfaceAPI is specified in an object-oriented but technology-independent Unified Modeling Language (ISO Standard)UML model and mapped to Distributed Component Object Model (Microsoft Public Specification)DCOM. This configuration allows easily addition of new programming language mappings to 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 without having to change the core of 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.
