Abstract

The invention discloses a parallel hybrid electric vehicle (PHEV) mode switching coordination control system based on interference compensation and a control method thereof. The control system comprises a driving module, a control module and a disturbance observer, and is simple and efficient, and close in logic. According to the control method, engine and motor torque errors, clutch friction torque errors, uncertainty of a system dynamics model, system modeling errors, elastic constants and damping coefficients of all parts and other factors are considered comprehensively, and the mode switching control system and the control method thereof based on the interference compensation are designed for the mode switching process, the interference observer is simplified to a low pass filter for interference compensation, and the control method is high in precision, simple and efficient, and is more suitable for promotion.

Description

technical field [0001] The invention belongs to the technical field of dynamic coordinated control of hybrid electric vehicles, in particular to a coordinated control technology for preventing power interruption or torque fluctuation during mode switching of hybrid electric vehicles, in particular to a coordinated control system and control method for PHEV mode switching based on interference compensation . Background technique [0002] As we all know, in recent years, resource and environmental problems have become increasingly serious, and the country's fuel consumption regulations and emission standards for passenger vehicles have also continued to tighten. In particular, many countries around the world have recently clarified the timetable for banning the sale of fuel vehicles, and traditional vehicles have been strongly impacted. . Hybrid vehicles not only inherit the power of traditional fuel vehicles, but also increase the cleanliness and environmental protection of ...
