Design and research on engine emulation system of HEV power train hardware-in-the-loop simulation platform

Abstract

Adopting test bench to do research on HEV is efficient at low costs, but in traditional test bench, the real engine is used to do lots of experiments, which produces a lot of tail gas, and the use of an engine is limited while safe ty is not high. This paper designs an engine emulation system based on the Electric Variable Transmission (EVT) simulation platform for the HEV power train. The high controllability motor is used instead of the real engine to provide power according to characteristics of the engine…
