Background technology
Continuous intensification along with global energy crisis; The harm aggravation of the exhaustion day by day of oil resources and atmospheric contamination, global warning; It is the main direction of following automotive technology development with reducing discharging that national governments and automobile enterprise generally recognize energy-conservation, and the development mixed power electric car is the feasible way that solves these two technical barriers at present.Mixed power electric car is divided series, parallel, the three kinds of forms of series-parallel connection of mainly containing by driving system structure at present.The series hybrid type of drive has the fixable advantage of engine working point, but energy process multiple conversions, overall efficiency is lower; Energy need not multiple conversions in the parallel connection combination drive mode, but engine working point changes with the variation of operating mode, and emission performance difference and control are complicated than tandem; Series parallel type combination drive mode has been taken into account the characteristics of above-mentioned dual mode, but complex structure, the difficult arrangement of each parts, the control difficulty is big, and cost can be in any more.
In recent years, Urbanization in China is accelerated day by day, and what be accompanied by is the Rapid Expansion of urban size and the rapid expanding of urban population, and urban mass-transit system faces unprecedented opportunity to develop.The present city bus recoverable amount of China has nearly 500,000 more than; But present most vehicle all is to be the day bus of power with the combustion engine; The non-constant discharging of the performance driving economy of conventional truck in the city is high, mainly is the influence that receives city terrain environment and operating condition particularity.China has formulated the research and development of enterprise that a lot of relevant policy supports preferential, that encourage are correlated with, all kinds of new-energy automobiles that scientific research institutions comprise various hybrid power passenger cars for this reason, has obtained some gratifying achievements.But on the whole, the hybrid power passenger car system is at fuel saving ratio at present, and aspects such as emission performance reach people's expectation value far away.
At present; The domestic hybrid power passenger car drive system that puts into effect mainly contains two kinds of structures, is respectively to be the drive system (like Fig. 1) of representative and to be the drive system (like Fig. 2) of representative with U.S. Eaton with China Fujian Fugong HEV Technologies Development Co., Ltd..Among Fig. 1; Driving engine (1) links to each other with self-acting clutch (3) driving disc spacing pressing; Self-acting clutch (3) is connected with drive motor (4); Drive motor (4) links to each other with drive axle (5), and driving engine (1) is connected with electrical generator (2) through belt, and electrokinetic cell (8) links to each other with drive motor (4) with electrical generator (2) respectively through electric machine controller (7).The key distinction of Fig. 2 and Fig. 1: the integrated starter-generator (2) among Fig. 2 has replaced the electrical generator among Fig. 1 (2); Increased automatic transmission with hydraulic torque converter (10) among Fig. 2; Driving engine among Fig. 2 (1) is coaxial linking to each other with integrated starter-generator (2); And among Fig. 1, driving engine (1) is to be connected with electrical generator (2) through belt.
Mainly there is following problem in two kinds of structures:
1, electrical generator (2) is to link to each other with driving engine (1) through belt among Fig. 1, and driving efficiency is low, and horsepower output is little.System needs bigger base ratio to turn round to increase, and do not have high range overdrive gear simultaneously with the raising speed of a motor vehicle, so maximum speed is lower.
2, among Fig. 2, added Automatic Transmission (10), complex structure, the control difficulty is big, and reliability, stability are difficult to guarantee.
3, two kinds of structures all can't be charged to electrokinetic cell (7) with external power grid.
Therefore be necessary existing systems is improved.
Summary of the invention
