Description
Technical field
The present invention relates to a kind of series connection of pneumoelectric series-parallel hybrid electric system to turn control method for parallel.
Background technology
It is existing pneumoelectric series-parallel hybrid electric system as shown in Figure 1, as seen from the figure, the system includes coaxially arranged hair
Motivation 1, ISG motors 3 and main motor 5, wherein, ISG motors 3 are connected with engine output shaft by torsion vibration absorber 2, and
It is connected between ISG motors 3 and main motor 5 by clutch 4, main motor is directly connected to drive axle driving vehicle.According to from
The working condition of clutch 4, the system can be divided into series model and paralleling model, and series model refers to that clutch is in separation shape
State, main motor are unique driving parts；Paralleling model refers to that clutch combines, and engine or main motor are driving parts.
Series connection, which turns paralleling model, at present following two control modes：(1) control of engine speed, ISG direct torques：If
Engine is not shut down, and engine is controlled using rotating speed, and rotating speed of target is main motor speed, and ISG motors use direct torque, target
Moment of torsion is 0Nm；If engine has been shut down, ISG motors are successful by engine start using direct torque, and then engine, which uses, turns
Speed control, rotating speed of target is main motor speed, and ISG motors use direct torque, target torque 0Nm.Due to gas engine
Response is slower, and the factors such as speed governing shakiness be present causes series connection to turn paralleling model conversion slowly.(2) ISG rotating speeds are controlled, and engine is adopted
With Throttle Opening Control and it is 0 throttle：If engine is not shut down, ISG is controlled using rotating speed, and rotating speed of target is main motor speed, is started
Machine is using Throttle Opening Control and is 0 throttle；If engine has been shut down, ISG motors are first successful by engine start using direct torque,
Then ISG is controlled using rotating speed, and rotating speed of target is main motor speed, and engine is using Throttle Opening Control and is 0 throttle.This controlling party
The shortcomings that formula is：When engine has load (such as air compressor of air conditioner works) or higher main motor rotating speed, ISG is limited by itself
Power limit causes speed governing slower；The response full-vehicle control instruction of clutch combination rear engine participates in driving, because gas machine is oily from 0
Door arrives target throttle low-response, and driver feels that vehicle has power interruption.
Exist slowly, after patten transformation in power from the foregoing, it will be observed that the control mode of series connection turn parallel connection now has patten transformation
The problems such as disconnected.
The content of the invention
It is an object of the invention to provide a kind of series connection of pneumoelectric series-parallel hybrid electric system to turn control method for parallel, to solve
Patten transformation existing for existing control mode is slow, the problem of power interruption be present after patten transformation.
In order to realize the above object the technical solution adopted in the present invention is：A kind of pneumoelectric series-parallel hybrid electric system
Series connection turns control method for parallel, comprises the following steps：
(1) when vehicle meets to enter condition in parallel, judge whether engine has completed machine, if not completing, ISG motors
Controlled using rotating speed, rotating speed of target is main motor speed；
(2) when engine speed reaches the rotating speed n1 of setting, supplied to engine；
(3) when engine speed reaches the rotating speed n2 of setting, engine ignition；
(4) when engine speed reaches the rotating speed n3 of setting, engine has completed machine, and now ISG is controlled using rotating speed,
Main motor rotating speed is followed, and engine uses Throttle Opening Control, and given throttle value；
(5) when engine and main motor speed discrepancy are less than setting speed difference, clutch combines, and vehicle enters and gang mould
Formula, engine participate in driving.
The rotating speed n1 set is 200rpm.
The rotating speed n2 set is 400rpm.
The rotating speed n3 set is 550rpm.
The setting speed difference of engine and main motor is 50rpm.
The outstanding feature that pneumoelectric series-parallel hybrid electric system series connection of the present invention turns control method for parallel is that series connection turns parallel connection
During pattern, ISG motors are controlled using rotating speed, follow the rotating speed of main motor, and engine is Throttle Opening Control and given suitable oil
Gate value, speed governing responds quickly, and enters in paralleling model rear engine response ratio speed regulation process and controlled and throttle using engine
Rear hybrid power system power failure-free will be combined in clutch soon for 0 mode by being worth.
Brief description of the drawings
Fig. 1 is existing series-parallel hybrid electric system structure chart；
Fig. 2 turns paralleling model control flow chart for present invention series connection.
Embodiment
Below in conjunction with the accompanying drawings and the present invention is described further specific embodiment.
As shown in Fig. 2 pneumoelectric series-parallel hybrid electric system series connection of the present invention turns control method for parallel and comprised the following steps：
(1) when vehicle meets to enter condition in parallel, judge whether engine has completed machine, if engine has been completed
Machine, now ISG controlled using rotating speed, follow main motor rotating speed, engine control be Throttle Opening Control, and given suitable throttle
Value；If not completing, ISG motors are controlled using rotating speed, and rotating speed of target is main motor speed；
(2) when engine speed reaches the rotating speed n1 of setting, control magnetic valve supplies to engine；
(3) when engine speed reaches the rotating speed n2 of setting, engine ignition；
(4) when engine speed reaches the rotating speed n3 of setting, engine has completed machine, and now ISG is controlled using rotating speed,
Main motor rotating speed is followed, and engine uses Throttle Opening Control, and give suitable throttle value；
(5) when engine and main motor speed discrepancy are less than setting speed difference, clutch combines, and vehicle enters and gang mould
Formula, engine participate in driving.
Each setting speed value of engine is as follows in the present embodiment：The rotating speed n1 set is 200rpm, the rotating speed n2 of setting
For 400rpm, the rotating speed n3 set is 550rpm；The setting speed difference of engine and main motor is 50rpm.
Above example is only used for helping the core concept for understanding the present invention, it is impossible to the present invention is limited with this, for ability
The technical staff in domain, every thought according to the present invention, the present invention is modified or equivalent substitution, in embodiment
And any change done in application, it should be included in the scope of the protection.
