TameTire powered by Michelin
Additional functions and applications with CarMaker
IPG has integrated TameTire into the IPG CarMaker vehicle dynamics simulation in order to model the interaction of the vehicle/tire system and to realistically simulate the complex control loop of driver, vehicle and road.
The integration with CarMaker has expanded the functions and applications of TameTire even further. CarMaker’s tire standstill model, for instance, extends the working range. The GUI-based test automation enables extensive track test catalogues to be run and offers tools for parameter studies. Inflation pressure tolerances and tread stiffness values in combination with vehicle parameters can be automatically investigated over night.
With CarMaker, the virtual driver (IPGDriver) for realistic simulations of complex closed-loop maneuvers is able to systematically modify and manipulate tire inflation pressures or temperatures during the test run. Practically directly from the cockpit, systematic adjustments of operating parameters or a defined pressure loss to test tire pressure monitoring systems (TPMS) are implemented in the test run. A status observer can query all TameTire parameters with millisecond-accuracy to ensure event-based testing. Last but not least, the loss power model from CarMaker delivers the corresponding performance summary based on rolling resistance, lateral and longitudinal slip, self-alignment and deformation of the tire for the purpose of performing energy analyses.
