Research on New Electric Hybrid Powertrain with Two Speed Ratios

Abstract

In order to provide a new power train for electric hybrid vehicles that is simple in structure and lower in cost with higher fuel efficiency. A new power train for electric hybrid vehicle was designed with only one motor, one engine and a two speed ratio gear box. It has six different operation modes and can meet the vehicle driving requirements，and can provide pure electric drive, independent engine drive and hybrid drive with two speed ratios.
