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)*m*g) instead of grad*m*g) and road
gradient influence on roll resistance (cos(arctan(grad)*m*g 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 "<DRAG>"
- 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).

step were averaged to speed values > 0.
