Hybrid electric vehicle system switching control method based on dual-rotor motor dynamic coupler

Abstract

The invention discloses a hybrid power vehicle system based on a dual-rotor motor power coupler and a working mode switching control method of the hybrid power vehicle system. The hybrid power vehicle system comprises an engine system, a power driving system, a dual-rotor motor power coupler control system and an ABS. System control is in seven working modes which are respectively the stop power generation mode, the pure electric running mode, the charging running mode, the engine running high-speed running mode, the hybrid power diving mode, the back-up running mode and the braking energy recovery mode. Transmission efficiency can be improved, the optimum control over engine fuel economy can be achieved, braking energy can be recovered through the dual-rotor motor power coupler, the energy-saving effect is also achieved, and running stability of a vehicle can be achieved in the working mode switching process.

Description

technical field [0001] The invention belongs to the field of vehicle power transmission control, and in particular relates to a hybrid vehicle switching control method based on a dual-rotor motor power coupler. Background technique [0002] In recent years, with the ups and downs of international crude oil prices, the changing international political situation, energy problems and environmental pollution have become increasingly serious, energy conservation, emission reduction, and low-carbon economy have become one of the important measures to achieve sustainable development of the national economy and society. While maintaining the driving performance of traditional vehicles, hybrid vehicles have significant advantages such as high efficiency, energy saving, low noise, and low emissions. It has become one of the effective ways to solve the problems of environmental pollution and energy shortage caused by traditional vehicles. [0003] The concept of the dual-rotor motor dy...
