Abstract

The invention provides a control framework and device for a hybrid electric vehicle. Through control over universal gears, an engine and the torque, in various possible gear and torque distribution combinations, the engine is made to work at the working condition point of the lowest fuel consumption rate in real time as much as possible. Through reasonable design of module functions, the calling relationship among modules and the data flow direction among the modules, the control reliability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a control method and device for a hybrid electric vehicle. Background technique [0002] With the rapid development of human society, environmental pollution and energy crisis have become two major problems that increasingly plague human existence. In recent years, the new energy vehicle industry has become a key development area of ​​the world's automotive industry. New energy vehicles represented by electric vehicles and hybrid vehicles can reduce fuel consumption and exhaust emissions, which is of great significance to the sustainable development of the human environment. [0003] The hybrid electric vehicle control method is the core part of the hybrid electric vehicle vehicle control, including the specific modules and functions in the control process, the mutual calling relationship between the modules, and the data flow between the modules, etc. The metho...
