And reach best working condition in the range of very little wherein, at this moment or oil consumption is minimum or noxious emission is minimum, or
Two is all right.However, practical road conditions are ever-changing, not only show in the speed of driving wheel, while being also manifested by driving wheel institute
It is required that torque.Therefore, realize that rotating 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 contiuously variable 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 discrete to provide limited mostly

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, whole system it is less efficient.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 efficient.However, this system needs two sets of independent subsystems, cost high；On
Hybrid power system is stated by reasonably controlling associated power source, although the operating modes such as pure electric vehicle, combination drive can be realized,
The system shafting is more, complicated, requires the space layout of motor and drive mechanism high, exploitation and design cost height.
