VECTO x.x (current source)

TODO

• Traction interruption: No engine rev down - hold rpm until new gear engaged (Allison)

VECTO 2.2

• Bugfix: Error in Declaration Mode Pneumatic System aux power calculation ([kW] were interpreted as [W])
• Bugfix: Error in Declaration Mode Electric System aux power calculation
• Moved gear-specific Full Load Curves to Gearbox File
• Combined Drag Coefficient * Cross Sectional Area in one input parameter
• Updated .vgbx file format (Added gear-specific Full Load Curves)
• Updated .veng file format (Removed gear-specific Full Load Curves)
• Updated .vveh file format (Combined Drag Coefficient * Cross Sectional Area in one parameter)
• Updated Generic Vehicles (new file formats)
• Removed WHTC Correction Factor Calculation. Now in external tool, VECTO-Engine.
• Test Options are now only available in Engineering Mode
• Gearbox Editor now shows generic and user-defined shift polygons (if available)
• Various small updates in GUI
• Added 'Create JIRA Issue' dialog

VECTO 2.1.4

• Bugfixes in start gear and (A)MT shift model
• Updated Coach .vcdv file for higher speeds to avoid extrapolation
• Renamed output "FC" to "FC-Map" for better clarification
• Same header for g/h and g/km output
• Reduced minimum turbine speed for 1C-to-2C AT up-shift condition from 900 to 700rpm.
• Updated cross wind correction parameters to current White Book values

VECTO 2.1.3

• PwheelPos output in VSUM file.
• Implemented new Cd*A(v) method
• Bugfix in TC model
• Bugfix: Unit error in Cd(v) methods caused incorrect Delta-Cd value being used

VECTO 2.1.2

• Improved TC iteration for higher precision
• Extended possible TC speed ratio

VECTO 2.1.1

• Bugfix: Incorrect torque calculation in AT/TC model caused early up-shifts
• Updated C-to-C shift strategy with acc_min rule (see V2.1)

VECTO 2.1

• Limit engine rpm in torque converter operation acc. > acc_min
• Shift up (C-to-L, L-to-L) if acc. > acc_min and next-gear-rpm > threshold
• C-to-C up-shift condition based on N80h engine speed (instead of N95h)
• Pwheel-Input (SiCo Mode)
• FC [g/h] is always saved in output (in addition to [g/km]), not only in Engine Only mode
• Updated DEV options for AT update
• "DEV" tab is now "Test"
• GUI: Corrected air density unit in GUI
• Bugfix: Format error in .vmod header

VECTO 2.0.4-beta4_Test (Test Release)

• Transmission loss extrapolation Errors are now Warnings in Engineering Mode.
• Bugfix: Error in TC Iteration caused crash
• Bugfix: Minimizing Graph window caused crash
• Fixed error in cycle conversion
• Errors if full load curve is too "short"

VECTO 2.0.4-beta3

• Bugfix: VECTO didn't check if the full load curve covers the speed range up to nhi. Now it will abort if the full load curve is "too short"
• Update in Torque Convert model: Allowed engine speed range up to n95h (before: Pmax-speed)
• Bugfix: Rare crashes caused by gear shift model
• Bugfix: Error in engine inertia power calculation
• Torque Converter losses in modal results
• Implemented speed profile cleaning for very small values. (Caused shifting back to first gear when decelerating.)
• DEV Option for advanced CSV format output (units line, additional info)
