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

New input parameters


The new input fields (see table below) are optional in this version. When this release candidate
will be an official version manufacturers MAY certify their new vehicles using the new input
parameters. As from 1 st July 2019 the new input fields will become mandatory. Further details are
provided in the timetable on the next page.


Default values when the new input parameters are not provided:
Input parameters vehicle - Table 1 Annex III


Field
Default value


VehicleCategory
No default value but input 'rigid truck' will be converted automatically into 'rigid lorry'


ZeroEmissionVehicle
'No'


NgTankSystem
'Compressed' (only applicable to gas vehicles)


SleeperCab
'Yes'


Input parameters ADAS - Pt. 8 Annex III


Field
Default value


EngineStartStop
'No'

'No'


EcoRollWithEngineStop
'No'


PredictiveCruiseControl
'No'


Currently only the fuel type NG PI for the engine certification is allowed by 2017/2400. For LNG
vehicles, therefore, the engine fuel type has to be set to NG PI and at the vehicle level
NgTankSystem has to be set to liquefied. For CNG the same engine fuel type is used but
NgTankSystem has to be set to compressed.

Bugfixes:

[VECTO-602] - Error in simulation without airdrag component
[VECTO-589] - Scheme .xml error


VTP Simulation Mode

Verification Test Procedure (VTP) Simulation Mode
Similar to Pwheel mode, different cycle format (see user manual)
Requires:

Vehicle in declaration mode (XML)
Measured driving cycle
Parameters for engine-fan model


VECTO calculates the gear based on the wheel speed and engine speed (and
vehicle parameters) and ignores the gear provided in the driving cycle
Fuel consumption interpolation is done using the engine speed from the cycle
and calculated power demand (to avoid wrong engine speeds due to wrong gear
selection)
Simulation uses all auxiliaries except engine fan

Engine fan is modeled separately, power demand depends on fan speed (see user manual)


Auxiliary power selected according to segment table, BUT power demand
depends on vehicle speed

v < 50 km/h: Urban
50 <= v < 70 km/h: Rural
v >70 km/h: Long haul


Gear and fuel consumption in the driving cycle are optional for now, may be used
in future versions

Notes for using Vecto 3.x with AAUX


The AdvancedAuxiliaries module requires the number of activations
for pneumatic consumers (brakes, doors, kneeling) and the
(estimated) total cycle time. This can be configured in the .APAC-file
(actuations file). For standard bus/coach cycles (i.e., the cycle file
contains “bus” and “heavy_urban” or “suburban” or “interurban” or
“urban”; or the cycle contains “coach” (case insensitive)) the
actuations file already contains the number of activations and the
cycle time. For other cycles the filename without extension is used
to lookup the activations in the .APAC file (case sensitive)


Vecto 3 uses an average auxiliaries load (determined by the AAUX
module depending on the settings) for the simulation. The AAUX module
computes the fuel consumption in parallel to VectoCore and accounts for
smart consumers (e.g., alternator, pneumatics, …).


Output:

The .vmod file contains both, the fuel consumption calculated by VectoCore
(per simulation interval) and AAUX (accumulated and per simulation interval).
Columns in .vmod file:

AA_TotalCycleFC_Grams [g]: accumulated fuel consumption as computed by the AAUX model,
considering smart consumers
FC-Map [g/h]: fuel consumption as computed by VectoCore interpolating in the FC-Map,
using an average base load of auxiliaries
FC-AUXc [g/h]: fuel consumption corrected due to engine stop/start
(currently not applicable)
FC-WHTCc [g/h]: WHTC-corrected fuel consumption (not applicable in engineering mode)
FC-AAUX [g/h]: fuel consumption per simulation interval, derived from
AA_TotalCycleFC_Grams
FC-Final [g/h]: final fuel consumption value with all (applicable) corrections applied
(stop/start, WHTC, smart auxiliaries)


Output .vsum

Columns in .vsum file:

FC-Map: total fuel consumption as computed by VectoCore interpolating in the FC-Map,
using an average base load of auxiliaries
FC-AUXc: total fuel consumption corrected due to engine stop/start
(currently not applicable)
FC-WHTCc: WHTC-corrected fuel consumption (not applicable in engineering mode)
FC-AAUX: fuel consumption per simulation interval, derived from AA_TotalCycleFC_Grams
FC-Final: final fuel consumption value with all (applicable) corrections applied
(stop/start, WHTC, smart auxiliaries)

Various bugfixes


Pwheel (SiCo) Mode

Function as already available in Vecto 2.2 also added in Vecto 3.0.2

For details see user manual: Simulation Models / Pwheel Input (SiCo)


Measured Speed Mode

Functionality already available in Vecto 2.2 added in Vecto 3.0.2

Driving cycle not defined by target speed but by actual speed. No driver
model in the simulation.
Gear and engine speed can be specified in the driving cycle.
In this case the Vecto gear-shift model is overruled.

For details see user manual: Calculation Modes / Engineering Mode / Measured Speed


.vmod File Update

In Vecto 3.0.2 the structure of the modal data output has been
revised and re-structured. Basicaly for every powertrain component
the .vmod file contains the power at the input shaft and the
individual power losses for every component. For the engine the
power, torque and engine speed at the output shaft is given along
with the internal power and torque used for computing the fuel
consumption.
For details see the user manual: Input and Output / Modal Results

Update Notes > Release Notes
Segment Table header


VECTO 2.0

Updated CSV file format. Now only one header with units included.
Changed input file comment symbol form "c" to "#".
Replaced old Demo/Default Data with "Demo Vehicles"
Updated User Manual
Declaration Mode
Updated GUI including Charts
New internal Graph for VMOD files (replaces GRAPHi)
Shift polygons can be set separately for each gear
Removed rated power (not used anymore)
Removed rated engine speed form engine file. Now calculated form vfld file.


VECTO 1.4.RC8

Bugfix: Eco Roll didn't go into motoring operation when Overspeed-Limit was reached (could cause higher FC than Overspeed Mode)
Minor update in demo data (12t motoring curve)


VECTO 1.4.RC7

Bugfix: Error in road gradient resulted in altitude error
Speed reduction in smaller steps to get closer to full load curve (before speed was sometimes reduced too much and caused problem with gear shifting)
Updates in demo data


VECTO 1.4.RC6

Bugfix in torque converter calculation


VECTO 1.4.RC5

Bugfix: Gears using torque converter and transmission loss maps may cause invalid "out of engine operation range" errors
Null values for FzISO will abort calculation
Exact road gradient calculation (sin(arctan(grad)mg) instead of gradmg) and road gradient influence on roll resistance (cos(arctan(grad)mg instead of m*g)
Torque converter update: rpms over rated speed are not allowed.
Fixed Wheels inertia in Demo Data


VECTO 1.4.RC4

Bugfix: FC interpolation failed when load points matched map points exactly.
Bugfix: Invalid "FC= -10000!" errors when outside of FC-Map
Bugfix: Vehicle stand-still at end of cycle was ignored (distance-based cycles only)
FC extrapolation will not abort calculation. Invalid FC values are marked in output as "ERROR".
No abortion if transmission output and input torque have different signs (In>0, Out<0). (Caused "Transmission Loss Map invalid" error messages)
Eco-Roll revised. New rules:

Engages if Pwheel < 0
Disengages if Underspeed is reached.


Look-Ahead Coasting now uses real coasting also if road gradient > 0 which means the coasting deceleration can be so high that no braking is necessary. In this case the braking phase will be omitted and the total deceleration time can be shorter than expected by the given target coasting deceleration.
"Minimum (actual) speed" instead of "Min. Target Speed" for Eco-Roll, Overspeed and Look Ahead Coasting
Major update in Gearbox/Toque Converter:

Torque converter can be defined in multiple gears
Same gear numbers in output as in GBX file, i.e. first gear with TC is not "TC" or "0.5" but simply "1"
"Minimum time between two gear shifts" now also limits torque converter shifts
Unlimited number of gears and new gear list in GUI without fixed gear number
Improved gear shift model for torque converter
Driving Cycle Preprocessing and Gear Shift Model now use approximated efficiency values based in the transmission loss maps. Reduces calculation time significantly with little to no impact on fuel consumption.


Full load and drag curves (.vfld) can be defined for each gear separately.
Bugfix: Distance Correction didn't work right with Look Ahead Coasting. Now distance error is acceptable but at the cost of partly interrupted coasting phases. Should be revised in future updates.
Engine Only Mode: Engine motoring points can be defined explicitly in load cycle with ""
When speed is under 5km/h and engine in motoring operating then gearbox shifts to Neutral
Load-dependent rolling resistance coefficient
Start-Stop activation delay time can be defined in job file
File signing features added:

After each calculation a signature file (.vsig) is created which includes signatures for all input and result files. The file itself is also signed.
Signature files can be verified or manually created under "Tools" > "Sign or Verify Files"


Changes in header and new parameters in modal results (.vmod):

engine speed => n
torque => Tq_eng
Pe => Pe_eng
New: Tq_clutch = torque at clutch (before clutch, engine-side)
New: Tq_full = full load torque
New: Tq_drag = drag torque
Removed: Pe_norm, n_norm


Changes in summary results (.vsum)

total altitude change instead of average gradient
Auxiliary energy consumption for each auxiliary


Removed: Pe_norm, n_norm
Same job file list for BATCH and STANDARD (Job file list does not change when switching mode)
Updated some error messages (units)
Driving Cycle stop times corrected (No more zero stop times).
