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 safety 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. An engine simulation model is built in Simulink, including engine dynamic torque model, engine fuel & efficiency model, engine control system model and input control model. To verify the designed system, engine emulation experiments are performed finally, which show that this engine emulation system can emulate the engine, including dynamical torque characteristic and fuel & efficiency. Therefore, this paper provides a new method to the research of test bench of vehicle.
