Arbiter_Limiter_Chrysler_MDD

Module –

High-Level Description

This module arbitrates between the HaLF, DST, and PA features to produce the input and output torque overlay signals. It also provides an output showing which features are enabled.

Variable Data Dictionary

For details on module input / output variable, refer to the Data Dictionary for the application. Input / output variable names are listed here for reference.

Module Internal Variables

This section identifies the name, range and resolutions for module specific data created by this module. If there are no range restrictions on the variable, the term “FULL” is placed into the table for legal range.

User defined typedef definition/declaration

This section documents any user types uniquely used for the module.

Constant Data Dictionary

Calibration Constants

This section lists the calibrations used by the module. For details on calibration constants, refer to the Data Dictionary for the application.

Program(fixed) Constants

Embedded Constants

All embedded constants whose values are provided in Eng units will be evaluated to the equivalent counts by using the FPM_InitFixedPoint_m() macro within the #define statement.

Local

Global

This section lists the global constants used by the module. For details on global constants, refer to the Data Dictionary for the application.
