Software Module Implementation
Sub-Module Functions
Initialization Functions
AssiSumLimInit1
INIT: AssiSumLimInit1
Design Rationale
Design follows implemenetation in FDD.
Module Outputs
Refer ‘AssiSumLimInit1’ block in FDD
Module Internal
None
PERIODIC FUNCTIONS
Per: AssiSumLimPer1
Design Rationale
Design follows implementation in FDD.
Store Module Inputs to Local copies
Refer to FDD
(Processing of function)………
Refer to FDD (Block ‘AssiSumLmtPer1’)
Store Local copy of outputs into Module Outputs
Refer to FDD
Interrupt Functions
None
Server runnables
SetManTqCmd
| Function Name | SetManTqCmd_Oper | Type | Min | Max | |
| Arguments Passed | VehSpd_Kph_T_f32 | float32 | 0.0F | 511.0F | |
| ManTqCmd | float32 | -8.8 | 8.8 | ||
| ManTqCmdEna | boolean | FALSE | TRUE | ||
| Return Value | ManTqCmdRtn_Uls_T_enum | Std_ReturnType | 0 | 1 | |
Design Rationale
Argument names should have _arg added to end of names for ManTqCmd and ManTqCmdEna.
Store Module Inputs to Local copies
None
(Processing of function)………
Refer ‘SetManTqCmd’ block in FDD
Store Local copy of outputs into Module Outputs
None
Local Function/Macro Definitions
None
GLObAL Function/Macro Definitions
None
Tranisition FUNCTIONS
None
Known Limitations With Design
.
Tustin Filter does not have a library block in design or code (could be added to component after CR EA4#6619 is completed).
SetNtcSts.CallLocation should include AssiSumLimInit1 in DataDict.m (see CR EA4#12283).
Range for MotVelFilLp is incorrect and could cause overflow. Should be max of 1350, not 62500. This will be addressed in future design with CR EA4#12743.
