EffShift Parameters

The following EffShift parameters are read from the file
“Declaration/EffShiftParameters.vtcu” if this file exists.
(A sample file is provided in the VECTO archive)
All parameters are optional, if a parameter is not provided the default value
(see table below) is used


Parameter name
Value
Explanations


Rating_current_gear
0.97
Defines the minimum fuel efficiency advantage in a candidate gear to trigger a gear shift (i.e. 3% of a value of 0.97) - applies only for AMT transmissions


Rating_current_gear_APT
0.97
Defines the minimum fuel efficiency advantage in a candidate gear to trigger a gear shift (i.e. 3% of a value of 0.97) - applies only for APT transmissions


RatioEarly(Up/Down)shiftFC
24
In gears with a higher total drivetrain ratio (axle plus gearbox) than this parameter, “Efficiency shifts” are disabled, i.e. the shifts are only triggered by the shift lines. Rationale: Gear shift in this gears are primarily triggered by pow er demand.


AllowedGearRangeFC
2
Defines the gear range for candidate gears for “Efficiency Shifts”(+/-) - applies only fot APT transmissions


AllowedGearRangeFCAPT
1
Defines the gear range for candidate gears for “Efficiency Shifts”(+/-) - applies only fot APT transmissions with ≤ 6 gears Allowed


GearRangeFCAPTSkipGear
2
Defines the gear range for candidate gears for “Efficiency Shifts”(+/-) - applies only fot APT transmissions with more than 6 gears


AccelerationFactorNP98h
0.5
Defines the reduction of driver target acceleration in the engine speed range betw een nT98h and nP98h


ATLookAheadTime
0.8
Defines look ahead time for rating of fuel consumption for AT transmissions.


Declaration Missions

The missions simulated in declaration mode folder “DeclarationMissions” if this folder
exists.
A folder with all declaration missions is provided in the VECTO archive

LongHaul is the current candidate cycle #31
Previous LongHaul cycle is provided as LongHaul_old
Both LongHaul candidate cycles #13 and #31 are provided as well


Cycles are only read once on application start

Handling of exempted vehicles

Axle configuration and sleeper cab are optional input parameters for exempted
vehicles (XML schema 1.0 and 2.2.1).

OEMs are recommended to provide these parameters for exempted vehicles.
If the axle configuration is provided as input parameter, the MRF contains the vehicle
group.
The sleeper cab input parameter is also part of the MRF if provided as input.


Input parameters MaxNetPower1/2 are optional input parameters for all exempted vehicles.

If provided in the input these parameters are part of the MRF for all exempted vehicle
types
It is recommended that those parameters are used to specify the rated power also for
PEV (pure electric vehicles)
