The paper presents an investigation into the effect of Half-Toroidal CVU dynamics on the transient behaviour of a completed powertrain under the 80% throttle condition. Description of the derivation of model of the H-T CVU as well as that of a complete powertrain is provided. Simulations were carried out to gain a good understanding of the transient behaviour of the powertrain as well as its components. For simplicity, a piecewise curved gear ratio map is assumed in the simulation. The obtained results show that significant transient exist in complete powertrain during a hard vehicle acceleration. The presented simplified H-T CVU model describes its effect to the dynamics of a completed powertrain effectively. © Institute of Materials Engineering Australasia Ltd 2005.
