Continuously variable transmissions have made notable progress, especially in the automotive industry, in recent years. In this work we study the performance of a mid passenger car provided with an original Power Split CVT (PS-CVT) system. The main advantage of the proposed solution is to improve the efficiency of the CVT by means of a power flow without recirculation using two separate phases of operation. By means of a simulation model we evaluate the vehicle's fuel consumption with the hypothesis to consider the value of transmission ratio speed that minimises the specific fuel consumption. Furthermore the PS-CVT performance is compared with that of traditional CVT.

Abstract
Continuously variable transmissions have made notable progress, especially in the automotive industry, in recent years. In this work we study the performance of a mid passenger car provided with an original Power Split CVT (PS-CVT) system. The main advantage of the proposed solution is to improve the efficiency of the CVT by means of a power flow without recirculation using two separate phases of operation. By means of a simulation model we evaluate the vehicle's fuel consumption with the hypothesis to consider the value of transmission ratio speed that minimises the specific fuel consumption. Furthermore the PS-CVT performance is compared with that of traditional CVT.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
