Description
Technical field
The present invention relates to the vehicles for having internal combustion engine and rotating electric machine.
Background technique
In the past, have motor and generator as engine and rotating electric machine hybrid vehicle (HEV,
In (Hybrid Electric Vehicle), for the purpose of improving fuel efficiency and/or driving performance, it is known that having makes to start
The transmitting of rotary force between machine and generator disconnects or the clutch (patent document 1) of connection.In the vehicle, do not needing
In the case where power generation, above-mentioned clutch is set as the disconnected load to mitigate engine and generator, hereby it is achieved that fuel is imitated
The raising of rate, the raising of driving performance.
However, in the vehicle for driving wheel by rotating electric machine as hybrid vehicle, when increasing to rotation
Application voltage Vd that rotating motor applies and when increasing speed, as the rotation speed of rotating electric machine rises, rotating electric machine can
The torque of output is in the trend being gradually reduced.This is because the rotation speed along with rotating electric machine rises, in the electric rotating
The inside of machine generates the induced voltage Vr relative to application voltage Vd in opposite direction.As a result, relative to voltage Vd, rotation is applied
The state that the electrical current of rotating motor becomes the electric current for being restricted to be determined by Vd-Vr is produced as speed increases by rotating electric machine
Raw driving force is gradually reduced.
Following countermeasure is usually carried out in HEV as the countermeasure for increasing associated driving force decline with the speed is mitigated:
When the driving force generated by rotating electric machine increases along with speed and begun to decline, so-called weak magnetic is carried out to the rotating electric machine
Control eliminates induced voltage Vr to mitigate driving force decline.
For example, being typically used as IPM (the Interior Permanent Magnet Motor: interior of rotating electric machine in HEV
Set formula magneto) in motor, weak magnetic control, which is flowed by attached electric current Id in stator coil, to be carried out.That is, fixed
In subcoil other than flowing and having the driving current Iq for making to generate with the rotating excitation field of the magnetic field orthotropic of rotor magnet, also flow
There is an extra current Id for generating magnetic field on the direction parallel with the magnetic line of force of rotor magnet, as a result, above-mentioned rotating excitation field
Rotary phase offset of the phase relative to rotor reduces above-mentioned induced voltage Vr.In addition, relative to using extra current Id's
Weak magnetic control will drive rotating electric machine merely with the driving current Iq for generating above-mentioned orthogonal rotating excitation field without using Id
Control is known as orthogonal control.
In other words, weak magnetic control is by allowing to inhibit to increase together with speed with extra current Id associated power consumption
Motor generation driving force decline.Even if however, carry out weak magnetic control, induced voltage Vr also with speed increase and after
Continuous to rise, although power consumption increases and generates driving force and do not increase, the efficiency of the rotating electric machine as motor is gradually reduced.
As a result, in HEV, in the medium high speed area that the weak magnetic carried out for rotating electric machine controls, consumption electricity
The increase of power becomes significantly with the increase of speed, meanwhile, the generation driving force from rotating electric machine continues to decline, and works as decline
When the driving force of the bottom line to needed for maintaining speed, become limit speed (that is, the max speed that can be reached).
Fig. 4 is the driving force to wheel transmitting driving force shown in the previous HEV that engine is used as to generation driving force
The figure of an example of the structure of transmission mechanism.Previous vehicle 400 shown in Fig. 4 have engine 402, the 1st rotating electric machine 404 with
And the 2nd rotating electric machine 406.Diagram thick line in Fig. 4 is shown schematically in engine 402, the rotation of the 1st rotating electric machine the 404, the 2nd
The rotary force transmission path of the mutual transmitting rotary force (rotation torque) of rotating motor 406 and wheel 408.The rotary force passes
Path is passed for example to be made of rotary shaft, gear etc. (not shown).
The mutually transmitting rotation between engine 402 and/or wheel 408 and the 1st rotating electric machine 404 of 1st branch unit 410
Power.In addition, the 2nd branch unit 414 mutually passes between the 1st branch unit 410 and/or wheel 408 and the 2nd rotating electric machine 406
Pass rotary force.
Wheel 408 is in the state of will be used as the switching device 412 of clutch to be set as disconnected, by passing through battery 430
And the 2nd rotating electric machine 406 driving acted.Engine 402 is for making the 1st rotating electric machine 404 carry out power generation movement, the 1st rotation
Motor 404 is rotated with engine 402 together always, is charged to battery 430.In addition, when slowing down etc. and dress will be switched
Setting 412 and being set as disconnected simultaneously stops engine 402, as a result, by by the of the external force torque drive from wheel 408
2 rotating electric machines 406 charge to battery 430.
In said structure, the maximum driving force for driving the 2nd rotating electric machine 406 of wheel 408 that can generate is for example such as Fig. 5
It is shown to change like that with vehicle velocity V one.Here, horizontal axis shows vehicle velocity V, and the longitudinal axis shows driving force P.In addition, the line of diagram solid line
500 schematically show the maximum driving force that the 2nd rotating electric machine 406 can be realized under each speed.
In the example shown, vehicle velocity V th0 is the vehicle for starting to generate the induced voltage Vr that cannot be ignored in the 2nd rotating electric machine 406
Speed.It is specified value Vth0 velocity band below in vehicle velocity V, induced voltage Vr is small to the degree that can be ignored, the 2nd rotating electric machine
406 are driven by orthogonal control, can generate the driving force until Pomax.
On the other hand, in the region that vehicle velocity V is more than specified value Vth0, continuing for the 2nd rotating electric machine 406
In the case where orthogonal control, the maximum value for generating driving force sharply declines along line 502 shown in diagram single dotted broken line.Therefore,
In the speed for being more than Vth0, weak magnetic control is carried out to the 2nd rotating electric machine 406.As a result, the 2nd rotating electric machine 406 can be defeated
Maximum driving force out changes along line 500, and driving force mitigates relative to the decline degree of speed.
Then, when the maximum driving force for the 2nd rotating electric machine 406 that vehicle velocity V further increases and changes along line 500 reaches
When the driving force Poth of the bottom line to needed for maintaining speed, speed reaches the limit values (that is, the maximum speed that can be reached)
Vomax。
In above-mentioned previous vehicle, the induced voltage Vr that is generated in the 2nd rotating electric machine 406 with vehicle velocity V increasing
Add and increase, due to the electric current Id controlled for weak magnetic increase and cause consume electric power increase.That is, vehicle velocity V is bigger, to driving
The consumption electric power that the generation of power does not contribute directly more increases, and fuel efficiency runs down.
In addition, depending on the situation, with only using the engine of capacity identical as engine 402 as power source and
The vehicle of non-so-called HEV is compared, can be by only driving wheel 408 and the maximum speed that reaches by the 2nd rotating electric machine 406
Vomax can become lesser value.
On the other hand, including comprising above-mentioned patent document 1, do not find teaching for the document of the following countermeasure of HEV: should
Countermeasure be used to mitigate because of weak magnetic as described above control caused by with the increase for increasing associated consumption electric power of speed and/or mention
The maximum speed that height can reach.
