VI-grade releases v19.0 product suite

VI-grade today announced the release of v19.0 of its software product suite. The release includes major product features and several usability enhancements in the following products: VI-CarRealTime and VI-Driver (real-time software); VI-DriveSim (driving simulation solutions); and VI-Automotive, VI-Motorcycle, VI-Aircraft (vertical products).

Selected new features of VI-CarRealTime v19.0 include:

1. Investigation Mode:

• Automatic model variant response module
• Allows to easily execute a given plan of experiments

        – Define model parameters values and range
        – Select events or scenario to be tested
        – Define the metric to be monitored

• Automatically generate the related reports

2. Model improvements:

        – New engine mount layout options (bushings on body chassis, torque rods)

• Vehicle chassis flexibility with body-on-frame architecture
• New demo vehicles

        – SUV crossover
        – Pick-up truck

• Improved driveline modelling options, to specify e.g. gear shifting maps or specific inertias.
• Design time scaling factors for suspension elements (dampers, springs, bumpers…)

 3. Tire Models

• CDTire RealTime

        – Available for handling maneuvers

• FTire 2019-1

       – acc & /hil versions integration
       – Improved computational efficiency

• TameTire 5.1
• MF-Tyre/MF-Swift 7.3
• MegaRide

       – AdheRide/ThermoRide models integration
       – Realtime capable version available

 4. Adams Car Interface: new properties export added

• Frequency bushing
• Rack & pinion (Pfeffer model)
• Suspension auxiliary longitudinal dynamics identification

5. Vehicle Performance modules

• VI-SpeedGen can optionally consider the suspension travel while predicting the limit speed profile computation
• (For motorsport applications): Aerodynamic balance and electric motors regeneration state can be parametrized on the on-track position

6. Miscellaneous

• VI-CarRealTime solver now able to produce additional output signals:

        – Roll center height for all full vehicle simulations
        – ABS & TCS activity

• Possibility to configure multiple solver plugins
• Scriptable (python) custom post-processing
• VI-CarRealTime SDK now includes an executable able to perform simulations with forced “Save&Restore” operation

Selected new features of VI-DriveSim v19.0 include:

• VI-DriveSim environment opened to 3rd party vehicle solvers

       – Protocol documentation
       – Template for Matlab/Simulink

• Input File management

       – VI-CarRealTime model input files can be used for different experiments:
       – Override road data file
       – Redefine vehicle initial position/orientation

• Possible to inherit the lap sensor directly from the road file (explicit reference to a drd file still supported for special cases)

7. Steering feedback

• Support of angle tracking control mode in addition to the regular torque tracking mode

8. Body Feedback

• Active belts systems with independent left/right actuators now supported by the graphical interface

“I’m very impressed with the new DOE expansion (Investigation Mode) of VI-CarRealTime v19. For us it will be one of the most significant updates VI-CarRealTime has introduced over the past releases” – said one of the customers participating to the VI-CarRealTime v19 beta program.

The new releases, developed on top of Adams2018, are available on the completely revamped VI-grade download area at the link: https://www.vi-grade.com/en/reserved_area/software_download.
