Model validation

Application of the following procedure to validate

  • ur model:
  • 1. Verify that the TameTire testing procedure can be

applied successfully on a third party machine

  • 2. On vehicle testing:

Steady state Braking

Braking tests with a trailer

Braking tests performed on Michelin’s test trailer on a 245 / 35 R 20 Pilot Alpin 4 The braking force Fx is controlled until the desired maximum slip ratio (~50%) is reached To increase the clarity of the following graphs a Pacejka fit is performed on the experimental data

Michelin’s vision for TameTire

Our answer for Tire Modeling: TameTire

  • Employed internally by Michelin for Tire Development

For passenger cars and racing tires

  • Used outside Michelin

Vehicle dynamics simulations Virtual chassis design and set-up, virtual development loops HIL and Driving simulators (driver in the loop)

  • Key advantages

Thermal & real time abilities Representing real tire physics Competitive Tools for TameTire model feeding are available

  • Virtual Scaling Factors
  • Real Tire characterization process is robust
  • Representative tire database available

Michelin’s vision for TameTire

TameTire is opened towards our customers

  • Our Strategy = being able to support a wide deployment
  • Efficient Customer Support

Powered by the IPG + Michelin partnership

  • Customer Oriented Model

Integration of customer needs for future developments Measurement process for tire characterization successfully tested on external machine (NTRC)

Continuous Improvement & Progress Strategy

  • A living model, periodically updated
  • Merging multiple tire performances models

XY-Forces and Torques, steady-state and transient Rolling Resistance TPMS (Rolling Radius, evtl. Eigenmodes in the future…)

  • New features added regularly (e.g. v3.0 recently released)
  • Continuously enhanced performances

precision, calculation time…
