Changelog
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)*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).
