FB MS 3.0 Detailed description of function The control unit model of the Motronic is made up of the following main parts: EG SY MSF AS KO

Input variables: Processing and diagnosis of the sensor signals, derivation of further variables System variables: Initializations, calculation cycles etc. Engine control functions: Contain the functional groups to calculate the setting variables, e.g. torque coordination, injection, ignition, idle control etc. Output signals: Conversion of the setting variables into hardware-dependent setting signals Communication: Representation of the interfaces to the fault code memory management, customer service, driver, application etc.

The structure of the SG functions has been revised. The aim is a modular and more comprehensible structure. Checking and data flows are separated to a great extent. Data and checking flows are represented by different lines. Transfer of the data on the upper structure levels is performed by vectors.

Grundblöcke (allgemeines): - Bei Blöcken mit der Kennzeichnung "NOV" am Ausgang wird der Zustandswert des Blockes (Integratorinhalt, Flag, RAM-Zelle, etc.) im Dauer-RAM gespeichert (ansonsten im flüchtigen RAM). Im übrigen verhalten sich die Blöcke wie ihre Pendants ohne "NOV". - Die Haupteingangs- und Hauptausgangswerte ("in" und "out") weisen im Block-Icon kein Symbol auf; sie sind mit 0.0 (float) bzw.

Zustand: Innerhalb eines Zustandsautomaten ist jeweils genau ein Zustand aktiv, d.h. die zu diesem Zustand (Ellipse) gehörenden Aktionen werden ausgeführt. Der Name des Zustandes ist innerhalb der Ellipse dargestellt. Der Übergang von einem Zustand zum anderen erfolgt, wenn die Übergangsbedingung erfüllt ist. Dabei werden diesem Übergang zugeordnete Aktionen ausgeführt. Die Bedingung, die erfült sein muß, damit ein Übergang stattfindet, steht neben dem jeweiligen Pfeil; ggf. steht nur ein logischer Name für die Bedingung und die ausfürliche Beschreibung ist dem nachfolgenden Text zu entnehmen. Bevorzugt wird die Bedingung mit der niedrigsten Nummer. Für jeden Zustandsautomaten ist festgelegt, welcher Zustand beim Start des Automaten angenommen werden soll (S) und welcher Zustand bei erfüllter RESET-Bedingung (R).

ASCETSDB 1.23 ASCET-SD descripton of block library FDEF ASCETSDB 1.23 Function definition Graphical presentation of basic elements Basic elements are presented in the diagram as rectangular blocks. Communication between basic elements is displayed by connecting lines. The interfaces between basic elements are the pins at the block edges. Each block has return pin that outputs the result from the block. In addition to this, there are argument pins that provide the inputs into the block as well as method pins that are used for those methods without input arguments and without return values. The methods call up functions in the block.

Methods Arguments Return value ---------------------------------------------------------------------m1: out Float m2: compute in, inmx, inmn m3: reset -

The example given above shows a block with 3 methods: - The method m1 "out" has one return value The method "out" is called up by the request for the return value from the subsequent block outy, that is in the tenth position in the computing sequence in the 100-ms computing frame. - The method m2 "compute" has three arguments (in, inmn, inmx) yet no return value. The method "compute" is called up at the fifth position in the computing sequence in the 10-ms computing frame. - The method m3 "reset" has neither arguments nor a return value. This is therefore represented by the "method pin". If B_reset is true, then the method "reset" is called up first (1/) in the computing sequence.

Receive message are input variables of the function that are made available from another function. Send/Receive variables are output variables of the function that are used both within as well as outside of the function. Send messages are output variables of the function and are available for the other functions. Local variables are only made available and used within the function.

In the case of group characteristics and group maps, several characteristics and maps pick up the same datapoint distributions. To this end, the current datapoint from the datapoint distribution, e.g. SNM07LRNM, is first computed from the dependent parameter e.g. nmot. The computation of the output value for the group characteristic or map then follows using this current datapoint.
