Abstract
This paper deals with the virtual prototyping and performance analysis of an electric vehicle powertrain using testbench and ADAMS software. The powertrain in this paper is proposed for use in an electric vehicle and especially adopts the function of an infinitely variable transmission (IVT). The IVT can realize not only a continuously variable transmission (CVT) function but also the forward, reverse, and neutral states of the vehicle speed without a clutch and/or brake. In this paper, a novel powertrain configuration is designed using an epicyclic gear set which can realize the IVT function by controlling the angular velocity of its one element. The virtual prototyping using ADAMS software is described in order to analyze the power performance of the proposed electric vehicle. And the dynamic behaviors of the electric vehicle are simulated and investigated with various driving conditions focused on the power performances. The simulation results are verified with the experiments of the testbench.
