Description
Technical field
The present invention relates to automobile technical fields, more particularly to a kind of automobile hybrid power coupled system and hybrid power control
Method, apparatus processed.
Background technique
Existing dynamical system includes engine (internal combustion engine) and a biography being made of speed changer, differential mechanism and transmission shaft
Dynamic system.Its effect is driving power needed for providing driving wheel to vehicle.Internal combustion engine has certain speed and torque range,
And reach optimal working condition in the range of wherein very little, at this moment or oil consumption is minimum or noxious emission is minimum, or
Two is all right.However, actual road conditions are ever-changing, in the speed for not only showing driving wheel, while it being also manifested by driving wheel institute
It is required that torque.Therefore, realize that revolving speed and the torque of internal combustion engine are optimal, i.e. power optimum state, with driving wheel dynamic regime it
It matches, is the top priority of speed changer.
Speed changer currently on the market mainly has step change transmission and stepless transmission two major classes.Step change transmission segments again
It is manually and automatically two kinds.They are arranged by the different engagement of gear train or planetary gear train limited discrete to provide mostly
Output input speed ratio.The adjusting of wheel speed is driven then to realize by the velocity variations of internal combustion engine between two adjacent speed ratios.It is stepless
Speed changer, either mechanically, one electric-type of fluid pressure type or machine, unlimited can be provided in certain speed range continuously may be used
The speed ratio of selection, in theory, the velocity variations of driving wheel can be completed completely by speed changer.In this way, internal combustion engine can use up
Possible work is in optimized range of speeds.Stepless transmission is compared with step change transmission simultaneously, has speed regulation steadily, can be sufficiently
Many advantages, such as using internal combustion engine maximum power, therefore, stepless transmission are always pair of various countries' engineers research for many years
As.

When with accumulator, such as battery, when capacitor etc. is used in combination, the speed changer but also as energy conditioner, complete to speed and
Torque it is separately adjustable.
Motor parallel system has two parallel independent power transmission chains.One is made of traditional mechanical transmission, another
Item is made of one battery system of motor.Mechanical transmission is responsible for completing the adjusting to speed, and one battery system of motor is then completed
Adjusting to power or torque.For the potential for giving full play to whole system, mechanical transmission is also needed using stepless gearing method.
The advantages of serial hybrid system, is that structure is simple, flexible layout.But whole power pass through generator and motor,
Therefore the power requirement of motor is high, and volume is big, weight weight.Simultaneously as energy transport is by one electricity of machine twice, an electric machine
Conversion, the efficiency of whole system is lower.In parallel hybrid system, only partial power is by electric system, therefore, to electricity
The power requirement of machine is relatively low, total system it is high-efficient.However, this system needs two sets of independent subsystems, cost is high；On
Hybrid power system is stated by reasonably controlling associated power source, although pure electric vehicle and combination drive operating mode can be realized,
