Abstract

The invention discloses an electronic stepless speed regulating system for a hybrid electric vehicle. The electronic stepless speed regulating system comprises an engine, a clutch, a composite magnetic flux switching permanent magnet motor, an electric power module, a battery pack, a main reducer, vehicle wheels and a control unit. According to the electronic stepless speed regulating system disclosed by the invention, as the composite magnetic flux switching permanent magnet motor is adopted as a power distribution device, and a mechanical device such as a planetary gear, a sliding ring, a carbon electric brush and the like does not exist, so that loss consumption is low, and the structure is simple; multiple-mode running can be realized by adopting only one motor, so that the space is saved, and the comfortable degree is increased; and the engine works in a high-efficiency running region all the time, thus effectively improving the whole vehicle efficiency.

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 oil resources, the traditional automobile industry is facing a severe test. Therefore, the research and development of energy-saving and environmentally friendly new energy vehicles has become one of the strategic industries of governments around the world and one of the hot spots that experts and scholars at home and abroad pay attention to. As a category of new energy vehicles, hybrid vehicles stand out for their remarkable advantages of high fuel economy, low exhaust emissions, and long cruising range, and have been rapidly developed. [0003] One of the key technologies to effectively realize the basic functions of hybrid electric vehicles is to develop a high-performance ...
