Deep hybrid automobile driving device

Abstract

The invention relates to a deep hybrid automobile driving device, which is based on an electrical variable automatic transmission (EV-AT) double-rotor motor coupled power transmission system, and comprises a double-rotor motor system, a conventional small engine, a battery, a battery management system, a vehicle controller, a synchronous shifting mechanism, a tortional vibration damper and the like. According to the different layout modes and different driving modes of the double-rotor motor, vehicle layout falls into three types: a front transverse double-rotor motor front drive type, a front longitudinal double-rotor motor rear drive type and a front longitudinal double-rotor motor four-wheel drive type. Correspondingly, the vehicle adopts different loading schemes and related technical combination schemes.

Description

A deep hybrid electric vehicle driving device technical field The invention relates to a deep hybrid vehicle drive device, which belongs to the field of electric vehicles. Background technique Hybrid and electric vehicles are an important direction for the development of new energy vehicles. Electric vehicles are known as the future development trend with zero emissions, low noise, and diversification of electric energy sources. However, due to the limitation of driving range, it is difficult to Realize industrialization, while hybrid electric vehicles are remanufactured on the basis of traditional internal combustion engine vehicles, retaining the original vehicle engine, adding electric drive systems such as battery motors, and optimizing the operating conditions of the engine through vehicle optimization control, so as to achieve good performance. Fuel economy and emissions. Among hybrid electric vehicles, deep hybrid electric vehicles have the highest fuel-saving rate...
