Abstract

An electronic stepless speed regulating system for a hybrid power automobile based on a compound type switched reluctance motor comprises an engine, a clutch, the compound type switched reluctance motor, an electric power module, a battery pack, a wheel driving system, a control unit and the like. According to the electronic stepless speed regulating system disclosed by the invention, the compound type switched reluctance motor is used as a power allocation device and no mechanical devices, such as a planetary gear, an electric brush and a slip ring or a permanent magnet material are used, so that the electronic stepless speed regulating system has the advantages of low loss, simple structure and high reliability. The electronic stepless speed regulating system can realize the operation of multiple modes by adopting one motor, and thus the utilization rate of the space is high; and in addition, two power circulating paths which can be independently controlled are arranged, so that the flexibility and the redundancy are greatly improved. According to the electronic stepless speed regulating system disclosed by the invention, the engine can be enabled to be always positioned in a high-efficiency operation zone and the efficiency of an entire automobile is effectively increased.

Description

technical field [0001] The invention belongs to the field of automobile power, and relates to an input power distribution type hybrid electric vehicle speed regulating device. Background technique [0002] In recent years, with the deterioration of the global environment and the increasing shortage of fossil fuels, the traditional automobile industry is facing a severe test. Therefore, research and development of energy-saving and environment-friendly new energy vehicles has become one of the hotspots of strategic industries all over the world and domestic and foreign experts and scholars. As a kind of new energy vehicles, hybrid vehicles stand out with their remarkable advantages of high fuel economy, low exhaust emissions and long cruising range, and have been developed rapidly. [0003] One of the key technologies to effectively realize the basic functions of hybrid electric vehicles is to develop a high-performance electronically continuously variable transmission (E-CV...
