Abstract

The invention discloses a mixed power system which implements mixed connection power distribution by adopting an electric system. The invention is provided with two power systems; namely, a front cabin constitutes a parallel connection mixed power system by adopting an engine and an ISG motor; meanwhile, a rear wheel is additionally provided with an electric wheel formed by two hubs, which can carry out electric power-assistance. The power system has a plurality of operation modes and can switch among all operation modes under the control of the vehicle control unit according to different power requirements. By adopting the power system structure, the vehicle has good power performance and the reliability of the power system is greatly improved. Furthermore, the integrated vehicle generation of electricity and the hub motor driving of the invention can be carried out at the same time with more flexible working modes of the power system, and the engine can work at the optimized workingpoint for a long time.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a hybrid power system that uses an electrical system to realize hybrid power distribution. Background technique [0002] Hybrid electric vehicle is a technology that has emerged in recent years. It can achieve the goals of saving fuel, reducing emissions, and environmental protection. The power system of hybrid electric vehicles is generally divided into series, parallel and hybrid. Among them, there are many researches on series and parallel, and the technology is becoming more and more mature. Parallel hybrid power system is a structure with great development prospects. Generally, the power is compounded through mechanical devices. For example, the traditional parallel hybrid power system uses planetary gears as power distribution components. The system is characterized by simultaneous power generation and The function of electric drive, and realize the distribution of...
