Research of the hybrid power train dynamic test system

Abstract

Based on the technology of conventional engine dynamic test system, using high dynamic AC frequency conversion dynamometer, developing of the simulators of road load, vehicle inertia, driver etc., a heavy duty hybrid power train dynamic test stand is developed. The stand can supply a near real road environment for hybrid power train of the vehicle. The R&D of different coupling structure of hybrid power train can be executed in the test system. All kinds of vehicle performance tests including power performance tests, energy economy tests, special hybrid function tests etc. can be implemented in it. The developed hybrid power train dynamic test system is a useful tool for developing the key technology of hybrid electric bus. © 2010 WEVA.
