Full Vehicle Characterization

The characterization of a complete vehicle is possible thanks to the contribution of different teams of experts that master specific technical aspects and related testing activities. The activities carried out include:

  • Suspension kinematics and compliance
  • Full vehicle centre of gravity and inertia measurement
  • Ride and handling, including steering assistance maps
  • Powertrain and brake system performance mapping
  • Components measurement: damper, springs

Tyre modelling

  • IDIADA characterizes and builds tyre models using world-class facilities and tools such as test trailers, rolling drums and static force measurement benches.
  • All vehicles include MF-Tyre models generated by IDIADA or trusted partners that are refined during the correlation with complete vehicle models.
  • Cosin Ftire models and CD Tires are optional.

Model correlation

All IDIADA models are validated in three steps:

  • Off-line correlation of kinematics and compliance.
  • Off-line correlation of ride and handling through systematic comparison of simulation data and objective measurement data
  • Subjective sign-off by expert drivers based on a back-to-back comparison using IDIADA DiM 250 driving simulator and real vehicle driving on IDIADA’s test tracks and open roads. 
  • > 100 full

    vehicle test cases

  • > 30 system and

    component test cases

  • >90% correlation level
