A device and a method for reading out adaptation values of self-adapting functions from a motor vehicle control unit to an external readout unit are provided. The device consists of a motor vehicle control unit, an external readout unit, and a communication interface between the external readout unit and the motor vehicle control unit, the motor vehicle control unit including a nonvolatile memory for storing adapted parameters or parameter sets of the self-adapting functions. The motor vehicle control unit additionally includes a receiver for receiving at least one test value set transmitted by the external readout unit, a calculation unit for calculating at least one adaptation value as a function of the test value set and the adapted parameters or parameter sets, and a transmitter for transmitting the at least one calculated adaptation value to the external readout unit.

The present disclosure describes methods, systems, and computer program products for providing multi-level user interface theming. One computer-implemented method includes instantiating a shadow system and database schema for a new version software application in a shared database, the shadow system database schema containing aliases pointing to tables instantiated in a production database schema, instantiating a bridge database schema containing aliases pointing to each database table within the production database schema, preparing a bridge sub-system connected to the bridge database schema aliases, replicating database tables within the production database schema, for use by the bridge sub-system and adjusting the original database tables for structure and content consistent with the new version software application, deploying an upgrade sub-system and tools to complete adjustment of structure and content of the original database tables, and connecting an instantiated instance of the new version software application to adjusted database tables.

A system and method for database migration is provided. In an example embodiment, the database migration technique may include execution modules having a first connection to a source database and a second connection to a target database, and orchestration modules adapted to identify first and second subsets of statements from a single storage table, wherein the first and second subsets of statements are executed by the execution modules during an uptime period of the source database.
摘要:
A process control system for controlling at least one process actuator includes a first process model for driving at least one process actuator in such a manner that at least one process desired manipulating variable is generated for driving at least one process actuator; a second process model, which generates a process actual variable from at least one process actual manipulating variable of the at least one process actuator; and another process element for generating a comparison process actual variable. The first process model can be mapped by inverting the second process model, and a process actual variable difference, which is formed from a process actual variable and a comparison process actual variable, is fed via a control unit to the first and second process models. The process element is designed as a third process model with higher reproduction precision and includes at least one non-invertible process component.

A method for model-based determination of the total fresh air mass flowing into the cylinder combustion chamber of an internal combustion engine during an intake phase is described. The method includes, steps of ascertaining a first partial air mass on the basis of a first load partial model, the first load partial model having a linear behavior, ascertaining a second partial air mass on the basis of a second load partial model, the second load partial model having a nonlinear behavior, and determining the total air mass by adding together the previously ascertained partial air masses.

A control device for controlling an internal combustion engine with a variably controlled valve stroke and with a butterfly valve in an air intake tract is provided. The control device is equipped with devices with which the even running of the internal combustion engine is monitored and through which the butterfly valve is actuated in the closing direction when a defined uneven running threshold value has been exceeded and when the valve stroke is smaller than a specified threshold until the value drops below the uneven running threshold value again.
