Abstract

In this paper, the powertrain efficiency is analyzed for the input split type hybrid electric vehicle. For considering the powertrain loss, the power loss models of planetary gear and motor are applied. And, the mathematic equations of powertrain speed and torque are found by using the lever analogy. With the above models and equations, the powertrain efficiency is analyzed for the 0 to 180 km/h vehicle velocity range. From the analysis results, it is found that the transmission efficiency with the power loss of planetary gear is smaller maximum 2.1% than the transmission efficiency without the power loss of planetary gear.
