The identification of a T-CVT (Toroidal Continuously Variable Transmission) is dealt with. The model describing the T-CVT system is a model with exogenous time-varying parameters and, in order to facilitate the parameter estimation, the complete T-CVT model is split into two sub-models. The parameters of the first sub-model are estimated with the PMF (Poisson Moment Functionals) method around several operating points, while the parameter of the second sub-model, reduced to a pure integrator, is estimated with the LIF (Linear Integral Filter) method. These two methods belong to the continuous-time system identification methods. The complete T-CVT model accuracy is finally verified with experiments carried out with a test-bed and an actual vehicle.
