Abstract

The invention provides a parallel hybrid power-driven system and belongs to the technical field of automobiles. The parallel hybrid power-driven system solves the problems of complicated integral structure and unreasonable layout of the conventional parallel hybrid power-driven system. The parallel hybrid power-driven system comprises an engine, a storage battery and a motor capable of converting electric energy into mechanical energy, wherein the power output end of the motor is connected with an automobile axle; the motor is mechanically connected with the engine and can be driven by the engine; the engine is connected with an engine controller capable of controlling the engine to work; the engine is also electrically connected with a motor controller which is connected to the storage battery and can control the motor to work; the motor controller can make the motor in the state of converting the mechanical energy into the electric energy and charges the storage battery; and the motor can independently drive the automobile axle to work or drive the automobile axle to work together with the engine in the state of converting the electric energy into the mechanical energy under the control of the motor controller. The parallel hybrid power-driven system has the advantages of reasonable layout, low energy consumption, energy conservation, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to automobile power systems, in particular to a parallel hybrid drive system. Background technique [0002] With the increasing demand for environmental protection and the increasing shortage of non-renewable resources such as petroleum, many car manufacturers are paying more and more attention to the research and development of energy-saving and emission-reducing models, and various hybrid vehicles are gradually coming out. Under the background of the existing technology, the four-wheel drive hybrid electric vehicle can meet the needs of energy and environmental protection to the greatest extent, so it has more market prospects. The configurations of hybrid electric vehicle power systems developed at present include series, parallel and hybrid. [0003] For the parallel hybrid system, people have carried out long-term exploration and put forward various improvement schemes. For ...
