VI-MotionCueing

The innovative motion cueing strategy from VI-grade suitable with any motion platform architecture

VI-MotionCueing, developed in collaboration with the University of Padova (Italy), is based on an innovative algorithm which, given vehicle translational accelerations and rotational velocities, converts them into admissible movements of  the driver’s seat, for any motion platform architecture.

VI-MotionCueing is based on Model Predictive Control (MPC), a methodology that allows implementing a mathematical model of the vestibular motion perception and of the platform structure.

Tuning of VI-MotionCueing can be performed by modifying a set of parameters to achieve a satisfactory trade-off between best perception and the respect of the working area. 

Among them, it is possible to separately tune each direction of motion, the length of prediction horizon, the range of dynamics within which the algorithm operates.

Compared to the so-called “classical” approach, the usage of MPC allows to limit the platform motion without affecting the driver perception. Moreover, the typical shortcomings of the “classical approach”, among which the generation of opposite sign acceleration (motion inversion) and  the necessity of empirical tuning, are overcome.

Further advantages are:

  • Improved consistency between real vehicle dynamics and platform movements;
  • Possibility to take into account the hard constraints of the platform (displacements, velocities, acceleration);
  • Possibility to perform efficient prepositioning

Applications

  • Realistic motion platform movements (on all types of motion platforms)
  • Algorithm based on model predictive control that minimizes motion sickness
  • Better driver experience

Benefits

  • Effectively handles limits of the working space
  • Possibility of anticipating platform positioning based on vehicle dynamics prediction
  • Overcomes the problem of motion inversion
  • Respects the physics of the vehicle chassis motion without introducing empirical filters
  • Reduces motion sickness
