Drive system of a hybrid electric vehicle

Abstract

The invention discloses a drive system for a hybrid power vehicle. The drive system for the hybrid power vehicle is characterized in that the drive system is an integrated electric control unit which acquires the operation information of an accelerator pedal and an electronic gear shifting device respectively and controls an engine to drive the front wheels of the vehicle to operate; meanwhile, the integrated electric control unit controls a transverse flux permanent magnet motor to drive the rear wheels of the vehicle to operate through a power supply management system. Because of the adoption of the structure, the drive system for the hybrid power vehicle has the advantages that 1, the structure of a front-mounted drive system is greatly simplified, and the light-weight design of the hybrid power vehicle is realized; 2, the power output of the overall vehicle is adjusted in real time according to different vehicle situations, and the endurance is high; 3, the production cost of the hybrid power vehicle is controlled effectively; 4, the conventional front-wheel drive vehicle can be improved, and the drive system for the hybrid power vehicle is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the field of design and manufacture of electric vehicles, in particular to a driving system of a hybrid electric vehicle. Background technique [0002] As the number of cars increases year by year, the air pollution intensifies and the shortage of oil resources accelerates, seriously affecting the living environment and sustainable development of human society. After more than 100 years of development, traditional internal combustion engine vehicles have been quite mature in terms of power, economy, safety and comfort, but they are restricted by technical bottlenecks in energy issues and emissions, and have been difficult to meet the increasingly stringent environmental protection requirements. Regulations and people's needs for energy conservation and environmental protection. [0003] Pure electric vehicles have no exhaust emissions, low noise, and get rid of dependence on oil. They are ideal clean energy vehicles. However,...

Problems solved by technology

However, due to the limitations of current battery technology, the specific energy of the power battery is low, the mileage of a single charge is short, the power performance is not good, and the space occupied by the battery is large, heavy, expensive, and the corresponding charging facilities It is not perfect, so it is difficult to achieve large-scale industrialization of pure electric vehicles in a short period of time, and further technological breakthroughs are needed

In existing hybrid vehicles, the installed fuel engine retains the starter motor, and the transmission requires a reverse power steering mechanism, which has a complex structure and increases the difficulty of control
