Problems solved by technology

When the engine is used as an auxiliary power to intervene in power output, since the moment of inertia of the engine is much greater than that of the motor, frequent engine intervention will cause a great impact on the vehicle, which greatly reduces the driving comfort of hybrid vehicles.

Abstract

The invention provides a control method of hybrid power vehicle power distribution. The control method comprises the following steps: detecting a battery charge state and requirement torque parameters of a hybrid power vehicle, and changing power distribution modes of the hybrid power vehicle by a finished automobile comprehensive controller of the hybrid power vehicle among a pure power-driven mode, a hybrid power mode and a pure engine mode according to the parameters, wherein the hybrid power mode comprises a form a motor to an engine mode and a motor auxiliary mode, and in the motor auxiliary mode, an engine of the hybrid power vehicle is a main power source and a motor of the hybrid power vehicle is an auxiliary power source. According to the control method, in the motor auxiliary mode, the engine is controlled to be the main power source and the motor is controlled to be the auxiliary power source, so impacts on vehicles caused by the auxiliary power source frequently entering power input are weakened effectively, and driving comfort of the hybrid power vehicle is optimized.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, in particular to a control method for power distribution of hybrid electric vehicles. Background technique [0002] With the rapid development of the global economy, energy and environmental issues have become increasingly prominent, saving energy and protecting the environment has become a major challenge faced by all countries in the world. Low-carbon economic policies around the world have promoted the development of new energy vehicles. The technological progress, industrialization and application of new energy vehicles will drive the development of upstream and downstream industries and bring fundamental changes to human transportation and travel. As a new energy vehicle technology that can effectively reduce vehicle energy consumption—hybrid vehicle technology has become one of the focuses of governments, enterprises and scientific research institutions around the world.
