HEV : increase the efficiency of gasoline vehicles
Toyota Prius: one of the first industrialized HEVs
In Prius: a planetary gear provides speed coupling
The planetary gear: increasing car’s overall cost and weight
In this paper: Prius 2004 is simulated with Transmotor in place of planetary gear and generator

Topology of Transmotor Based HEV
The Engine power through Transmotor transfers to differential and combined with traction motor, provides the vehicle traction force.

Single mode: only traction motor Hybrid mode: motor and ICE◦ When vehicle reaches a specific speed◦ When battery’s SOC comes down to a specific percent◦ When demanded power is higher than a specific kWh
A complete drive cycle◦ Start◦ Accelerate◦ Cruise◦ Brake
