Technical field
The invention belongs to field of hybrid electric vehicles, it is related to DRIVEN BY AIR CONDITIONING COMPRESSOR device, more particularly to a kind of air-conditioning pressure
DRIVEN BY AIR CONDITIONING COMPRESSOR device of the contracting mechanomotive force from power assembly.
Background technology
Hybrid vehicle at least has two kinds of power sources, including engine and auxiliary power source.Engine is that mixing is dynamic
The main offer source of power Automobile drive power.Auxiliary power source can be for providing starting power for engine, and it is mixed that can also aid in
Close power vehicle provide driving force or by the kinetic energy of the power of engine or hybrid vehicle be converted into it is another be easy to storage
Energy.Under normal circumstances, engine is usually internal combustion engine, and auxiliary power source is motor or hydraulic motor.
With band driving starter-generator (Belt-driven Starter Generator, abbreviation BSG) or integrated actuating
The hybrid electric vehicle of generator (Integrated Starter Generator, abbreviation ISG), BSG/ISG starts with starting
The function of machine.The torque capacity of BSG/ISG motor determines by the torque request of starting engine, the highest of BSG/ISG motors
Rotating speed is determined by engine peak speed.
The only automobile of engine, compressor of air conditioner is driven by the power of engine.Exist in hybrid vehicle
The mode of operation that engine is shut down, the compressor of air conditioner decoupled that worked with engine is needed by extra power drive.Conventional side
Formula is independent motor and compressor of air conditioner is integrated into electric air-conditioning compressor, but needs a set of electric motor system, cost compared with
It is high.
Patent CN201310315498.6 proposes a kind of DRIVEN BY AIR CONDITIONING COMPRESSOR device for mixed power electric car：
