cosin/ip

1. fix: curve color palette selection
2. fix: occasional issue with file labelling in GUI

12. font selection for PNG export added in GUI
13. plot defining macros implemented

FTire/core

1. fix: effective out-of-plane bending stiffness (and thus mainly cornering stiffness) for a second inflation pressure, if defined, for small tires might have been larger than defined
2. fix: occasionally too small sidewall text size in animation window
3. fix: tire surface coloring for air flow and pressure distribution
4. n_tire_states data item added to interface numerics GUI
5. specification of slip and cornering stiffness as basic properties for tires without tread pattern definition made more accurate

FTire/fit

1. fix: occasional issue with Fx plots in FTire/fit

FTire/HILAC

1. added Support for SimWB 2021.2 and 2022.1

cosin/road

1. fix: center-line load-time low-pass filter evaluation
2. maximum road length of stochastic roads in animation increased to 2 km
3. road animation model accelerated for RGR with center-line roads
4. writing of RGU files made thread-safe
5. center-line projection in RGR road evaluation made more robust, avoiding unnecessary restarts and subsequent RT overruns
6. made center-line projection work fast and accurate even for distances to center-line up to 50 m
7. new option shclorig (’shift center-line into origin‘) in RGR header to let center-line start in global origin and along x-axis, evaluated at load-time​​

cosin/tools for tires

1. fix: camber thrust computation and output in FTire characteristics plots and fingerprint
2. too large Fz values in PAC2002 export mitigated
3. new agricultural demo tire
4. new button in analyze pane: ‚K&C restrictions‘ for convenient and fast display of K&C stability limits for VI-CarRealTime, CarMaker, CarSim etc.
5. final values of slip angle sweeps and camber thrust computations made selectable in configurable fingerprints
6. additional demo tires provided
7. rolling speed made selectable in PAC2002 export

cosin/tools for roads

1. fix: fast RGR header editing in case of RGR with center-line and if last option carries a numeric value
2. improved user info when loading huge CRG files
3. new info added to single location evaluation, telling if location is inside road data domain
4. zc0 and filtc data items added to ‘modify’ tab
5. proper dealing of ds=.. and closed options added to ‚modify‘ function
6. new functionality: fast comparison of two RGR files
7. additional output of center-line numerical properties in ‘inspect/center-line’ function
8. new features in center-line inspection:
   • display of curvilinear equidistant stations
   • more detailed quality measures

cosin/tools for Matlab

1. increased size of animation window if called from FTire blockset
