DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power transmission rotating electric machine and a moving power transmission device using the same, and more particularly to a device for electromagnetically transmitting power obtained from a prime mover to a load drive shaft.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. Hei 8-251710 proposes a power transmission rotating electric machine that electromagnetically transmits power obtained from a prime mover to a load drive shaft. This power transmission rotating electric machine has a first rotor connected to an output shaft of a prime mover, and
It has a second rotor connected to the drive shaft (load drive shaft) of the vehicle, and constitutes one rotating electric machine by both rotors. In this configuration, the relative rotational speed of the motor is controlled to transmit torque reaction forces to each other.

When the power transmission rotating electric machine is operated, for example, as a generator, a torque is directly transmitted from the first rotor to the second rotor. Therefore, a series type in which the motor is driven by the generator driven by the prime mover. There is an advantage that transmission efficiency is superior to that of a hybrid vehicle.

[0004]

However, in the power transmitting rotary electric machine disclosed in the above publication, it is necessary to supply an armature current to the rotor via a brush or a slip ring, which is a problem in terms of brush life and reliability. Was a weak point from.
The present invention has been made in view of the above problems, and realizes a power transmission rotary electric machine of a multiple rotor type rotary electric machine without using a rotary power supply mechanism such as a brush or a slip ring, and a vehicle power transmission device using the same. It is intended to be.

[0005]

According to the first aspect of the present invention, the first rotor is electromagnetically coupled to both the first stator and the second rotor so that energy can be transferred. Particularly in this configuration, the first rotor has a coil to which an induced voltage induced from the first stator and the second rotor is applied in series,
Thus, the transfer of the energy between the first stator and the first rotor is controlled through the electromagnetic coupling between the two rotors. That is, a current for electromagnetic coupling between the two rotors is supplied from the first stator to the first rotor through the electromagnetic coupling between the first stator and the first rotor. For example, a rotating magnetic field formed by the first stator causes an induced current in the first rotor, and the induced current causes a rotating magnetic field around the second rotor.

With this configuration, it is not necessary to supply current to the rotors despite the fact that the output of the prime mover can be transmitted electromagnetically directly between the two rotors, so that a rotary power supply mechanism such as a brush or a slip ring is omitted. It is possible to realize a power transmission rotating electric machine that is excellent in reliability and high-speed rotation without brush wear or the like. Further, when power is supplied to the first rotor through the rotary power supply mechanism as in the related art, the number of coil turns of the first rotor increases because current reduction is effective for various reasons. Although this configuration is complicated, this configuration does not have this problem.
The coil formation and coil insulation of the first rotor can be facilitated.

According to the second aspect of the present invention, since the second rotor has a permanent magnet structure, there is no need to supply power to the second rotor for electromagnetic coupling between the two rotors, and the electromagnetic force between the two rotors is eliminated. The coupling efficiency can be improved. In the configuration according to claim 3, since the second rotor has a squirrel-cage winding structure of the induction motor, there is no need to supply power to the second rotor for electromagnetic coupling between the two rotors, and The mechanical strength of the rotor can be improved.

According to the fourth aspect of the present invention, since the second rotor has an inductor core structure, there is no need to supply power to the second rotor for electromagnetic coupling between the two rotors, and the structure is simplified. And cost reduction can be realized. Claim 5
In the configuration described, since the outer conductor in the outer slot and the inner conductor in the inner slot are connected in series to form a closed circuit, the two electromagnetic couplings can share one core back, which is simple. Electromagnetic coupling between the first stator and the first rotor as an induction machine, electromagnetic coupling between the first rotor and the second rotor, and excitation from the former electromagnetic coupling to the latter electromagnetic coupling Power supply can be realized. Further, by supporting the core back, the first rotor can be favorably supported.

In the configuration according to claim 6, three or more closed circuit windings each having a spatially different phase are used.
A rotating magnetic field acting on the second rotor can be easily formed. In the configuration according to claim 7, the closed circuit winding connects at least a pair of outer circumferential conductors separated by an electrical angle of approximately π from each other and at least a pair of inner circumferential conductors separated by an electrical angle of approximately π in a saddle shape. Therefore, the winding operation can be simplified.

[0010] In the configuration described in claim 8, the closed circuit winding is:
Since the outer conductor and the inner conductor inserted in the outer peripheral slot and the inner peripheral slot which are adjacent to each other in the circumferential direction are connected in a rectangular shape, the ineffective length occupying the length of the coil turn is an electromagnetic core. , The amount of copper required for the closed circuit winding, the electrical resistance and leakage inductance of the closed circuit winding can be reduced, and the energy transfer efficiency can be improved.

In the configuration according to the ninth aspect, the outer conductor and the inner conductor are separately wound at a magnetic pole pitch substantially equal to the magnetic pole pitch of the stator, and then connected in series.
It is easy to manufacture coils with existing automatic winding equipment. Claim 10
In the configuration described above, since the windings of the first stator and the first rotor both form a rotating magnetic field by three-phase windings, the productivity is superior to the case of using windings of four or more phases. As compared with the case where two-phase windings are used, a rotating magnetic field can be produced with a better balance, and components such as capacitors are not required.

According to the eleventh aspect, the first rotor has two three-phase windings having a predetermined phase angle (π / 6 or π / 3). Since the magnetomotive force distribution is closer to a sine wave, torque fluctuation in energy transmission with the second rotor is reduced, and electromagnetic noise can be reduced. In the configuration according to claim 12, since the first rotor is fixed to the shaft portion of the electromagnetic core using the core back portion of the electromagnetic core, a method using the inner diameter surface and the outer diameter surface of the electromagnetic core is used. As a result, it is possible to avoid deterioration of the energy transfer performance and firmly fix the energy transfer performance.

According to a thirteenth aspect of the present invention, the controller has a first sensor for detecting a first rotor rotational position and a second sensor for detecting a second rotor rotational position. The first stator generates an AC current in synchronization with the rotation of the second rotor based on the detected position of the first rotor to control the induced current of the first rotor. Energy transfer.

[0014] In the configuration of claim 14, the load driving shaft is driven by the third rotor of the second rotating electric machine in addition to the first rotating electric machine composed of the above-described power transmitting rotating electric machine. Since electric power is exchanged with both rotating electric machines,
The electric power generated by one of the rotating electric machines can cause the other rotating electric machine to operate electrically, so that the imbalance between the output torque of the prime mover and the required torque of the load drive shaft can be electrically eliminated, and further surplus or shortage can be achieved. Can be temporarily absorbed or released by the storage means. Furthermore, even when the power storage means cannot absorb the regenerative electric power, the first rotating electric machine can also rotate the prime mover to absorb the regenerative electric power, thereby realizing a high-performance and low-loss moving power transmission device.

[0015] In the configuration of the fifteenth aspect, since the third sensor for detecting the rotational position of the third rotor is provided, variation and deviation between the rotational position of the second rotor and the rotational position of the third rotor are allowed. can do. In the configuration of claim 16, the output torque and the number of revolutions of the prime mover are determined based on the sum of the required output of the load drive shaft and the power demand of the power storage means, and the rotating magnetic field frequency of the first stator is set to the second value. The frequency of the voltage applied to the first stator is determined so as to synchronize with the rotation speed of the rotor.

Next, the electromagnetic transmission torque from the first rotor to the second rotor is determined, and the difference between the load torque and the electromagnetic transmission torque is set as the output torque of the third rotor. With this configuration, the first rotating electric machine mechanically transmits a part of the engine generated power as a part of the vehicle driving power through the transmission torque between the two rotors, and the remainder of the engine generated power is transmitted to the first rotating electric machine. Between the motor and the second rotating electrical machine through a power conversion process. That is,
Since the difference between the output torque and the electromagnetic transmission torque of the first rotating electric machine is compensated for by the second rotating electric machine, the prime mover can be operated in a desired suitable operation region regardless of the state of the load drive shaft.

[0017] In the configuration described in claim 17, since the prime mover is started using the torque given to the first rotor from the restricted second rotor, a large starting torque can be obtained. In the configuration described in claim 18, the prime mover is started by the torque given from the second rotor to the first rotor, and the torque received by the second rotor from the first rotor as a reaction force is generated by the second rotating electric machine. Compensate.
With this configuration, a start shock of the prime mover is not applied to the load drive shaft, and the start can be performed even when the vehicle is being driven by the second rotating electric machine.

According to the nineteenth aspect, a torque is applied from the first stator to the first rotor to start the prime mover. With this configuration, the motive power for starting the prime mover is supplied from the power storage means to the first rotor via the first stator, so that the prime mover can be started while the vehicle is running. At this time, the power loss of the second rotor caused by driving the first rotor can be compensated for by the second rotating electric machine.

According to a twentieth aspect of the present invention, when the second rotating electric machine is operated electrically, the induction winding of the first rotor is driven by the difference in rotation speed between the first rotor and the second rotor. Since a magnetic field is applied from the first stator to the induction winding so as to cancel the induced voltage generated, the induced current becomes zero, and the first rotor drives the second rotor, causing unnecessary energy consumption. There is no.

According to the twenty-first aspect, torque is applied from the first rotor to the load drive shaft through the second rotor and from the second rotary electric machine to the load drive shaft while the motor is stopped. Therefore, the load drive shaft can be driven with a large torque. In the structure according to the twenty-second aspect, the mechanical locking means for restraining the output shaft of the prime mover or the input shaft of the first rotor of the first rotating electric machine is provided, so that the torque of the first rotating electric machine is driven by the vehicle. For maximum use.

According to the twenty-third aspect, when the power regenerated by the second rotating electric machine during braking cannot be absorbed by the power storage means, the prime mover is driven by the first rotating electric machine.
A good braking effect can be obtained without damaging the power storage means due to overcharging. In the configuration according to the twenty-fourth aspect, when the vehicle shifts to the neutral state during traveling and the vehicle runs by inertia, the prime mover drives both rotating electric machines in an idling state. Further, at this time, the first rotor is electromagnetically energized by the second rotor, and the induced current caused thereby is canceled by the rotating magnetic field of the first stator.

In this way, the first rotor does not consume the kinetic energy of the load drive shaft during the coasting. In the configuration according to claim 25, since the speed increasing device is provided between the output shaft of the prime mover and the input shaft of the first rotor of the first rotating electric machine, the size of the first rotating electric machine can be reduced. Can be.

(Description of Winding Method of Induction Winding 222) First Rotor 22
The winding method of the zero induction winding 222 will be described with reference to FIG. FIG. 5 illustrates one phase (U phase) of the three-phase winding (induction winding) 222 which is obtained by unfolding the electromagnetic core 221 in a straight line and winding it around the electromagnetic core 221.

The winding start U1 of the U-phase winding passes through the inner circumferential side slot 2212 'in the direction perpendicular to the plane of the paper and goes up the side of the core back 2213 on the back side of the paper, that is, on the opposite side of the electromagnetic core 221.

The slot 2212 'enters the slot 2212', exits on the front side of the page, returns three slots in the circumferential direction, and passes through the first outer side slot 2212 to the back side of the page. Ends.

Next, the same winding method is repeated several times through the sixth inner circumferential slot 2212 ', which is a slot at the same pole position, to complete the winding for the next magnetic pole.
This is repeated several times in pairs of poles to complete the winding for one layer.
When wound in this way, the slots 221 on the same center line
The cross section passing through 2, 2212 'becomes a "U" -shaped closed circuit winding, and has a saddle shape as a whole.

Since the length per coil-turn wound around the electromagnetic core 221 is short and the coil end portion that does not link with the magnetic flux is short, the first rotor can be reduced in size and weight. Since the leakage inductance can be reduced, there is an advantage that the induction motor characteristics of the first rotor 220 can be remarkably improved.

The winding starts from the inner peripheral side slot 2212 ′ opposite to the inner peripheral slot 2212. In this way, the winding (wave winding) on the outer circumference side and the winding (wave winding) on the inner circumference side of the U layer are completed. Next, the winding ends of the outer and inner windings are electrically short-circuited. By doing so, the common U-layer winding on the inner and outer winding mounting surfaces of the electromagnetic core 221 is completed. Similarly, a V-phase winding and a W-phase winding are wound. Thereafter, winding start and end of each phase winding are electrically short-circuited. In the present invention, each phase was wound in a wave every turn, but as shown in FIG.
Fig. 12 shows a single coil that has been wound several times as necessary in a large arc.
After being formed into irregularities at the magnetic pole pitch as described above, it may be fitted into the slot of the electromagnetic iron core 221. According to the present winding method, currents in opposite directions flow through the windings accommodated in the inner circumferential slot and the outer circumferential slot, and the same operation and effect as the windings shown in FIGS. it can. (Modification 3) Another modification will be described with reference to FIG.

This modification shows another winding system of the induction winding 222 of the first rotor 220. FIG. 8 shows a three-phase winding wound around an electromagnetic core 221 similarly to FIG. (Induction winding) 222 for one phase (U phase) is shown. In FIG. 8, the electromagnetic core 221 has slots 22112, 22122, 22121 ′ of multiples of the number of slots and the number of teeth of the first stator 210 on both sides of the core back 2213.
22122 'and teeth 22111, 22112, 22
111 'and 22112'. The U-phase winding is composed of two phase windings U1 and U2 having a phase difference (electrical angle) shifted from each other by π / 6. Note that instead of π / 6, π /
The phase difference may be shifted by three. Each of the phase windings U and U2 is wound with a U-shaped cross section shown in FIG. 5 starting from slots adjacent to each other. In this example, the magnetic pole pitch is a slot pitch corresponding to a six-slot pitch. Similarly, the V-phase winding has a winding V1 having a phase difference of π / 6 from each other.
, V2, the W-phase winding is composed of phase windings W1, W2 having a phase difference of π / 6 from each other, and the U, V, W-phase windings are three-phase windings having a phase difference of ／ π from each other. An induction winding 222 is formed, and the beginning and end of each phase are electrically short-circuited.
The phase windings may be wound as shown in FIGS.

According to this embodiment, the magnetomotive force generated by the induced current flowing through each phase is closer to a sine curve, so that the torque ripple of the electromagnetic coupling between the first rotor and the second rotor can be reduced. Has the effect of reducing electromagnetic noise. (Modification 4) In the above embodiment, the winding of the induction winding of the first rotor 220 corresponds to the winding of the first stator, and FIG. As described above, the winding may be short, or the number of grooves for each pole and each phase may be plural. In short,
Of the first rotor, an inner conductor and an outer conductor provided on the outer periphery are connected in series to form a closed circuit winding, and an induced current generated in one conductor is guided to the other conductor, Any configuration may be used as long as electromagnetic coupling is performed with the second rotor 230.

The winding of the first stator 210 also has three phases,
The present invention is not limited to all-section winding, and a short-section winding may be performed by increasing the number of grooves for each pole and each phase in order to generate a more sinusoidal magnetomotive force. Further, a multi-phase winding other than the three-phase winding may be used. (Modification 5) Another modification will be described with reference to FIG.

In this modification, the second rotor 230 has a rotor structure of an induction machine. In FIG. 3, components having the same main functions as those of the first embodiment are denoted by the same reference numerals. In this embodiment, the stator winding 211 is a three-phase winding of distributed winding with four poles, 36 slots, and 78% short node lap winding. The U-phase winding is shown in FIG. The V-phase winding and the W-phase winding are wound around slots having a phase difference of 2π / 3 in the same winding manner to form a three-phase winding.

The induction winding 222 of the first rotor 220 is also
A winding similar to the stator winding 211 is wound around the electromagnetic iron core 221 so as to form a closed circuit winding on the outer peripheral side of the electromagnetic iron core 221. For example, the coil shown in FIG. 13 may be formed in a U-shape as shown in FIG. 10 and fitted to the inner and outer winding winding surfaces of the electromagnetic core. Then, to electrically short-circuit each other winding start end and the winding of the three phase windings is the same as the embodiment of FIG.

In the second rotor 230, a conductor 245 is die-cast with aluminum in a semi-closed slot 234 with a cage rotor, and both ends are short-circuited by short-circuit rings. It is obvious that the present invention is not limited to this embodiment, and that various other winding methods can be used. In this embodiment, the rotational speed of the rotating magnetic field of the stator is N0, the rotational speed of the first rotor is N1,
If the rotation speed of the second rotor is N2, the slip between the stator and the first rotor is S1, and the slip between the first and second rotors is S2, N1 = (1- S1) N0 (1) S1 = (N1-N0) / N0 (2) N2 = (1-S2) N1 (3) S2 = (N2-N1) / N1 (4) N2 = (1- S2) (1-S1) N0 (5) Eventually, based on the rotation speed information N1 of the first sensor 240 and the rotation speed information N2 of the second sensor 250, the rotation speed N0 of the rotating magnetic field of the first stator is calculated. Controlling the rotation speed N2 of the second rotor

However, in order to facilitate understanding, components having the same main functions as those shown in FIG. 1 are denoted by the same reference numerals. This modification is a modification of the two rotating electric machines 200, 3

The outer peripheral end of one slot conductor on one end surface side of the cage winding is connected to a slot conductor on the other end surface side through a communication groove 2220 provided in the outer peripheral portion of an iron core constituting the first rotor 220 in the axial direction. The inner peripheral ends of these slot conductors are short-circuited to the inner peripheral ends of the other slot conductors by so-called short-circuit rings 2221 and 2222.

One end face of the first rotor 220 is
0, and the other end face faces one end face of the second rotor 230. The other end surface of second rotor 230 faces second stator 310. That is, the second rotor 230 and the second stator 310 constitute a second rotating electric machine. Reference numerals 211 and 311 denote coils, and permanent magnets are fixed to both end surfaces of the second rotor 230, respectively. Further, a central portion in the axial direction of both rotors 220 and 230 serves as a so-called yoke to allow magnetic flux to pass in the circumferential direction.

(Description of Configuration of Motor Controller 150) The configuration of the motor controller 150 will be described with reference to FIGS.

The prime mover controller 150 controls the prime mover 10
A vehicle drive power demand value Pv ′ to be generated to zero is received from the system controller 500, and a throttle actuator (not shown) is driven based on the input value, and based on a signal from a driving state sensor (not shown) of the prime mover mounted on the prime mover 100. By controlling the valve opening time of the fuel injection solenoid valve, the ignition timing of an ignition device (not shown) is determined and the ignition device is driven. The combustion state of the prime mover 100 is controlled by the fuel injection control and the ignition control. Further, from the motor characteristic map (see FIGS. 20 and 21) stored in the microcomputer incorporated in the motor controller 150, an operating point (for example, FIG. 20, point C (Te) , N
e)) is obtained, and the opening degree θTH of the throttle valve for maintaining this operating point is obtained. The prime mover rotation speed Ne is sent to the system controller 500, and as described above,
The first inverter 600 is operated by the system controller 500 to control the transmitted and received power of the first rotating electric machine to secure the prime mover rotation speed Ne. << Operation explanation of rotating electric machine >> (Operation of first rotating electric machine) The first rotating electric machine 200 is shown in FIGS.
FIG. 4 shows a three-phase AC machine having a double rotor structure, in which the rotation angle signal θ1 of the first sensor 240, that is, the first rotor 220
Rotation angle signal and the rotation angle signal θ of the second sensor 250
2 That is, an electric operation or a power generation operation is performed based on the rotation angle signal of the second rotor 230.

The three-phase winding (first stator winding) 211 of the first stator 210 has a three-phase AC voltage Vmsinωot,
Vmsin (ωot + ２ / 3π), Vmsin (ωot
−2 / 3π), the first rotor 2 is driven by a three-phase AC current flowing through the three-phase winding (first stator winding) 211.
A rotating magnetic field having an angular velocity ωo is formed in the 20 induction windings 222. If the angular velocity of the first rotor 220 at this time is ω1 and the slip s = (ωo−ω1) / ωo, the amplitude is s
Vm, the three-phase induced voltage having an angular velocity of sωo is the first rotor 2
20 to generate a three-phase induced current in the first rotor 220.

The three-phase induced current is supplied to the second rotor 230
A rotating magnetic field is formed on the outer peripheral portion of the rotating magnetic field. In the stationary space, the angular velocity of the induced current is sωo and the angular velocity of the first rotor 220 is (1−s) ωo. Therefore, the second rotor 230 rotates at an angular velocity ωo as a synchronous motor or a synchronous generator, even though the angular velocity of the first rotor 220 is ω1.

Conversely, in this embodiment in which the second rotor 230 is a permanent magnet rotor, the first stator winding 21
The frequency of 1 is determined by the target number of revolutions of the second rotor 230, and the phase and amplitude are controlled to control the torque between the first rotor 220 and the second rotor 230. After all, in the first rotating electric machine 200, the first rotor 220 and the first stator 210 constitute an induction machine, the first rotor and the second rotor constitute a synchronous machine, and further, The secondary coil of the induction machine and the coil of the synchronous machine are connected in series.

Next, the torque of each part will be considered. A first generated voltage Vx induced by the first stator 210 and a second generated voltage Vy induced by the second rotor 230 are generated in the first rotor 220. Based on Kirchhoff's law, the currents of these two generated voltages in the circuit of the first rotor 220 are considered separately. In this case, the coil 22 of the first rotor 220 is
A power supply voltage component formed of a part of the induction voltage formed on a part of the coil 222 is supplied to a synchronous machine coil formed at the other part of the coil 222 on the synchronous machine side, and is supplied to the synchronous machine. That is, the induction current generated in the coil 222 by the induction machine portion has a current drive function as a synchronous machine coil in addition to the action of the induction current of the secondary coil of the conventional cage induction machine,
It is important in improving efficiency. Of course, there is a loss due to the resistance of the coil 222.
Since the impedance of the synchronous machine coil is connected in series with the resistor 22, only a part of the power is lost in the coil 222.

In this configuration, it is assumed that a three-phase AC voltage that matches the angular velocity of the second rotor 230 is always applied to the coil 211 of the stator 210. As a result, the portion obtained by removing the resistance loss from the AC power by the first generated voltage Vx is the second rotor in which the angular velocity of the current and the magnetic field in the absolute space are synchronized unless a so-called step-out phenomenon of the synchronous machine occurs. The permanent magnet 230 is subjected to electromagnetic interaction (synchronous mechanical operation) to be converted into torque and used effectively.

Next, the latter power supply voltage consisting of the second generated voltage Vy generated in the portion of the coil 222 on the synchronous machine side is applied to the portion of the coil 222 on the induction machine side, so that it is effective as described above. The electric power in the coil 222 is transmitted to the first stator 210 by the transformer action through the first rotor 220 by synchronizing the angular velocity of the electric current and the magnetic field in the absolute space, and the electric current and the electric current A torque is generated by an electromagnetic interaction with the rotor 220 of FIG.

After all, the combined operation of the induction machine and the synchronous machine described above is shown in a torque-angular velocity diagram as shown in FIG. Here, T1 is the total torque applied to the first rotor, Tt is the transmission torque between the two rotors, and T1-Tt is the torque between the first rotor 220 and the stator 210. When the first rotor 220 driven by the engine 100 is rotating at a higher speed than the second rotor 230, as can be seen from the above description, in the first rotating electric machine 200,
Part a of the output of the engine 100 is electromagnetically transmitted to the second rotor 230 through the first rotor 220,
The remaining b + c + d is the first rotor 220, the first stator 210
Is output as generated power through Here, b is the amount transmitted to the stator 210 by the power generation operation of the synchronous machine, and c + d is the amount transmitted to the stator 210 by the operation of the induction machine.

Therefore, in order to control the first rotary electric machine 200, the engine generated power Pe = a + b + c + d = T1 under ideal conditions ignoring charging and loss of the power storage means 700.
ω1 is set to be equal to the vehicle driving power request value Pv. That is, the engine 100 is operated at an engine operating point at which the above-described magnitude of the engine generated power Pe is generated with the best fuel efficiency.

Next, T1 and ω1 are determined by this,
Since ω2 is determined by the vehicle speed, the
It is understood that if all the generated power b + c + d is transmitted to the second rotating electric machine 300 at 0, power that satisfies the vehicle driving power required value Pv can be generated. That is, if the generated power (b + c + d) flowing out of the stator 210 is adjusted by the induction machine / synchronous machine, the generated power (b + c + d) is changed with respect to the moving power a by the transmission torque Tt. Because of the relationship shown in FIG. 14, the area a serving as the machine-generated power and the area b + c + d serving as the generated power can be set. As a result, by controlling the generated power of the stator 210, the a + b + c + d is the engine power T1
The mechanical power Tt and the generated power P1 can be equal to ω1.

After all, the maps (ω1, ω2, T1, T2) in which the power generated by the first rotary electric machine 200 is stored in advance.
(representing the relationship between t and the generated power P1) by substituting the required driving power values ω1, ω2, and T1 of the vehicle to obtain Tt and P1, and operate the first rotary electric machine 200 to be P1. Then, the second rotary electric machine 300 may be operated electrically to generate a torque difference (T2−Tt). Note that T2 is a vehicle drive torque request value Td '. In addition,
Such current control can be easily performed by ordinary vector control of the rotating electric machine.

Next, in the first rotary electric machine 200, when the rotation speed of the first rotor 220 on the engine 100 side is smaller than the rotation speed of the second rotor 230 on the load drive shaft side, The rotational power of the rotor 230 is the first rotor 22
0, the first stator 210 electrically drives the first rotor 220 by the electric action opposite to the power generation action.

As a result, the first rotary electric machine 200 has a passive force Pe (= T1ω1) with the engine 100 and a passive force Pv (= Ttω) between the second rotor 230 and the vehicle drive shaft.
The power generation or the electric operation is performed only by the difference from 2), and it is understood that these operations are controlled within the range possible in terms of mechanical characteristics by controlling the power or current of the coil 211 of the stator 210.

In the normal control, the power Pe generated by the engine is increased by the various losses and the required charging power of the power storage means 700. The phase θ of the second rotor 230
2 can be detected by a signal from the second sensor 250, and based on this, the phase of the three-phase AC voltage applied to the first stator winding 211 is set. (Description of Operation of Second Rotating Electric Machine 300) Second Rotating Electric Machine 300
Is based on the rotation angle signal from the second sensor 250 or the rotation angle signal from the third sensor dedicated to the second rotating electric machine,
An electric operation and a power generation operation are performed for operation control such as power running and braking of the vehicle, which will be described later.

In the electric operation, the rotational speed signal is obtained from the third sensor 350 (or the second sensor 250) to determine the angular velocity ωv of the third rotor 320, and the frequency of the second inverter 800 is synchronized with the frequency ωv. Each switch S1 to S6
To generate a three-phase AC voltage V2, and control the phase angle Δθ between the magnetic pole position of the third rotor 320 obtained from the rotation angle signal θ and the rotating magnetic field by the three-phase AC voltage V2 to a desired value. It is done by doing. The torque is adjusted so that the supply current is at a desired level.
Is controlled by changing the magnitude of the applied voltage by PWM duty control.

In the power generation operation, the three-phase AC voltage V2 is generated in the coil 311 by the rotation of the third rotor 320.
The amplitude of each phase voltage of the three-phase AC voltage V2 is
If the voltage exceeds 0, the switches S1 to S6 of the second inverter 800 are operated at the timing when the phase voltage is applied to the battery. If the duty ratio is controlled by PWM during the ON period, the amount of power generation, that is, the amount of generation of negative torque can be adjusted.

Since the power generation and electric control of the three-phase AC synchronous machine are well known, further description is omitted. In addition, the description of the operation in the case where the second rotating electric machine 300 is an induction machine or the case where the second rotating electric machine 300 is a synchronous switching rotating machine is publicly known, and thus the description thereof is omitted. (Operation of the speed increasing device) The speed increasing device 140 has a planetary gear structure in this embodiment, but may be an ordinary gear speed increasing device that is parallel to the axis.

In the operation, since the rotation of the prime mover 100 is accelerated and input to the first rotating electric machine 200, the output torque of the prime mover 100 can be absorbed by a torque of 1 / speed increase ratio, so that the first rotating electric machine 200 The physique can be reduced. << Control Description >> Next, the control operation of the present apparatus will be described. The control according to the vehicle state is performed by the overall control by the control unit 5003, and the control of the rotating electric machines 200 and 300 in the state determined by the control unit 5003 is performed by the control units 691 and 891 in the inverters 600 and 800. The control of the engine 100 is performed by a control unit in a prime mover (engine) controller 500.

The flow of signals between the control units will be described. The control unit 5003 determines command values for controlling the rotating electric machines 200 and 300 based on input data.
The control units 691 and 891 perform the operations of the rotating electric machines 200 and 3 based on the command value received from the control unit 5003.
00, and the prime mover controller 150 controls the prime mover 100 based on the vehicle drive power request value Pv received from the control unit 5003. In this embodiment, the control unit 5003 stops and starts the prime mover 100 as necessary according to the vehicle state. (Description of Overall Control by System Controller 500)
First, the overall control program stored in the ROM built in the control unit 5003 will be described with reference to FIG.

When an IG (ignition) switch 560 for commanding the start of the electric vehicle is turned on, initialization is performed (S100), and each data is read (S102).
As data to read, at least the accelerator pedal,
Vehicle operation information including operation information of the brake pedal and the shift lever, and the rotation speed N1 of the first rotating electric machine 200,
And the rotating electrical machine speed information including the rotation speed N2 of the second rotating electrical machine 300, the required charging / discharging power value Pb ′ of the battery received from the SOC meter 510, and the storage amount information.

Next, the shift lever positions P (parking), R
Based on (reverse), N (neutral), and D (forward), one of the following control modes including a parking mode, a reverse mode, a neutral mode, and a forward mode is selected, and the selected control mode is read in S102. The shift position corresponding control to be executed based on the data is performed (S104). Next, a vehicle condition corresponding control, which is a correction control based on the vehicle running conditions, is executed (S106). Next, a start or stop command to the prime mover and an engine control mode (S108), which is a rotating electric machine control accompanying the command, are executed. After that, S106 and S108
Is transmitted to the first inverter 600 and the second inverter 800, and a command to start or stop the prime mover 100 determined in S108 is given to the prime mover controller 150 (S110). It is determined whether the switch is turned off (S11).
2) If not turned off, the process returns to S102, and if turned off, the motor controller 150 and the control units 691 and 891 are terminated, and the self itself is terminated.

(Execution of D or R Range Control Mode) Next, a forward (D) travel control mode, which is one of the shift position corresponding controls in S104 and is executed when the D range is selected, will be described with reference to FIG. This will be described below. R
The reverse (R) traveling control mode executed at the time of the range selection determination is basically the same as the control, and a description thereof will be omitted.

First, the vehicle drive torque request value Td 'is calculated (S200). This vehicle drive torque request value Td '
Is obtained by a map search based on the vehicle speed, accelerator opening, brake state, and shift position. Next, the vehicle drive power request value Pd 'is determined (S202). This required vehicle drive power value Pd ′ is equal to the rotational speed N of the second rotary electric machine 300.
Speed and vehicle drive torque demand value T determined based on
It is determined by multiplying the product with d 'by a proportionality constant.

Next, an engine power demand value Pe 'is calculated as the sum of the vehicle drive power demand value Pd' and the already received charge / discharge power demand value Pb '(S204), and transmitted to the prime mover controller 150 (S206). . Next, the engine speed command value Ne ′ is transmitted from the prime mover controller 150.
Is received (S208). It should be noted that, as described later, the prime mover controller 150
In order to operate the engine 100 at the engine operating point on the torque-rotation speed plane that efficiently outputs e ′, the engine operating point is determined based on the fuel efficiency characteristics on this plane stored in the map, and the determined engine operating point is determined. Engine speed command value Ne '
Is transmitted to the control unit 5003,
Control unit 5003 receives engine speed command value Ne ′ from motor controller 150.

Next, the calculated engine power demand value P
The torque command values T1 'and T2' to be transmitted to the rotary electric machines 200 and 300 are determined from e '(S210). The process of determining the torque command values T1 'and T2' employed in this embodiment will be described below. In this embodiment, the first rotating electric machine 200
T between the stator 210 and the first rotor 220
x is the torque generated by the engine from both rotors 22
The transmission torque Tt between 0,230 is subtracted.

Electric power is generated in the first stator 210 accompanying this transmission torque Tt, and the two have the relationship shown in FIG. That is, the engine speed command value Ne ′ (angular velocity ω1 in FIG. 14), the engine generated torque T1 (= Te = engine power required value Pe ′ / ω1), and the second rotor 2
When the rotation speed N2 (the angular velocity ω2 in FIG. 14) of 30 has already been determined, as described above, the transmission torque Tt is obtained from these parameters based on the map showing the relationship shown in FIG.

After all, the torque command value T1 'for controlling the current to the first stator 210 is T1' = Tx + Tt
And it is sufficient. Therefore, in the following control, the torque command value T1 'is calculated by the above-mentioned method, and then the torque command value T2' of the second rotating electric machine 300 is calculated by subtracting the transmission torque Tt from the vehicle drive torque request value Td '. And send this. Note that the torque command value T2 'is calculated from the charge / discharge power required value P from the power generated by the first stator (Teω1-Ttω2).
It is equal to the value obtained by subtracting b ′ and dividing by ω2.

The inverters 600 and 800 convert the torque command values T1 'and T2' into the first and second rotating electric machines 20 and 800, respectively.
Invert them so that 0 and 300 occur. That is, the second rotary electric machine 230 generates a torque that matches the torque command value T2 ′ obtained by subtracting the transmission torque Tt from the vehicle drive torque request value Td ′. The value obtained by multiplying the torque corresponding to the torque command value T2 'by ω2 is the remaining power obtained by subtracting the transfer power Pb' of the power storage means 700 from the power consumption T2 · ω2 from the area (b + c + d). Is equal to

In the above calculation, the first rotor 220
Loss due to such factors is ignored for simplicity. (Execution of N Range Control Mode) Next, a neutral control mode, which is one of the shift position corresponding controls in S104 and is executed when the N range is selected, will be described below with reference to FIG. This control corresponds to a case where inertia running is performed with the shift position being neutral on a gentle downhill or the like. At this time, the engine speed is set to the idling speed in order to reduce fuel consumption.

First, it is determined whether the vehicle is running (S30).
0), otherwise return to the main routine and end this control. If the vehicle is running, the engine power demand value Pe 'is set to 0 (idling operation) regardless of the accelerator opening (S302), and transmitted to the prime mover controller 150 (S304).

Next, after receiving the engine speed command value Ne '(in this case, the idling speed Nidle) from the prime mover controller 150 (S306), the torque command value T1' of the first rotary electric machine 200 is set to 0. Set (S
308). More specifically, under this operating condition, the first rotor 220 transmits the transmission torque Tt from the second rotor 230.
And generated power. Therefore, a torque having the same magnitude as the transmission torque Tt and the opposite sign is generated between the stator 210 and the second rotor 230. After all, if the loss is neglected, the power loss of the second rotor 230 due to the transmission torque Tt is caused by the power generation of the first rotor 220, so that the first rotating electric machine 220 is driven so that the current of the coil 222 becomes zero. May be set to zero. Therefore, the torque command value T1 'here
Setting to 0 means that the second rotor 230 gives the first rotary electric machine 200 a torque command value T1 ′ that causes the coil 222 to generate a generated voltage having the opposite phase to the generated voltage generated in the coil 222. means.

Next, the torque command value T2 'of the second rotating electric machine 300 is set so that the electric power corresponding to the charging / discharging electric power request value Pb' of the power storage means 700 is satisfied by the electric power generated by the second rotating electric machine 300. Then, the process returns to the main routine (S310). The control (S106) for correcting the operating conditions of the rotating electric machines 200 and 300 will be described below.

(Transient Control) First, the transient control which is one of the vehicle condition corresponding controls will be described below. This transient control is executed when the rotational speeds of both rotors 220 and 230 are substantially equal except near zero. First rotating electric machine 2
00 is a composite motor of the type in which the secondary coil of the induction machine and the excitation coil of the synchronous machine are connected in series as described above. Therefore, when the rotation speeds of both rotors 220 and 230 are substantially equal, the following description is desirable. Because no state occurs
This is performed to provide a difference between the two rotation speeds.

More specifically, the angular velocity of the AC voltage of the stator 210 is generally the same as that of the second rotor 2 except for a special mode (when the rotors are operated out of step).
It is equal to 30 angular velocities ω2. In this state, when the rotation speeds of both rotors 220 and 230 are equal, even if an alternating voltage of angular velocity ω2 is applied to stator 210 to form a rotating magnetic field of angular velocity ω2, the angular velocity of coil 222 of first rotor 220 also increases. Since it is ω2, no induced current is generated in the coil 222. Also, between the two rotors 220 and 230, the mechanical rotation speed of the permanent magnet of the second rotor 230 and the mechanical rotation speed of the conductor of the first rotor 210 match, and the rotating magnetic field of the second rotor 230 causes No voltage is induced in the coil 222.

Accordingly, when the road gradient or the like changes, the vehicle speed decreases, and the rotation speed of the vehicle drive shaft 910 approaches the rotation speed of the prime mover 100, the torque of the prime mover 100 cannot be transmitted to the vehicle drive shaft, and continuous running cannot be performed. there is a possibility. Therefore, in S106, the angular velocity ω1 of the first rotor 220 (related to the rotation speed of the prime mover) and the second rotor 23
The absolute value of the difference from the angular velocity ω2 of 0 (related to the rotation speed of the shaft of the vehicle) is smaller than the predetermined value A (| ω
1−ω2 | <A), and if so, execute this transient control.

In this transient control, first, the motor controller 150 is instructed to forcibly change the engine speed command value by a predetermined amount to the acceleration side or the deceleration side based on the power storage state of the power storage means 700 and the running state of the vehicle which are read in advance. (S400), the torque command value T of the first rotary electric machine 200
1 'is forcibly changed by a predetermined amount (S402). In the first rotating electric machine 200, the magnitude of the torque T1 between the first stator 210 and the first rotor 220 is equal to that of the first rotor 22.
Since there is a predetermined quantity relationship from 0 to the magnitude of the transmission torque Tt to the second rotor 230, in the D range running mode, the transmission torque Tt can be reduced by lowering the torque command value T1 '. The reduction of the torque T1 and the transmission torque Tt reduces the engine load and increases the rotation speed N1 of the first rotor 220. Therefore, when the engine speed command value Ne 'is increased during power running, it is preferable that the torque command value T1' be reduced. At this time, the power storage means 700 temporarily takes out the stored power,
Alternatively, electricity is stored.

Since the change in the torque T1 of the first rotary electric machine 200 due to the change in the torque command value T1 'is interlocked with the change in the transmission torque Tt as described above, the required vehicle drive torque request value Td' is reduced. In order to maintain the torque, the torque command value T2 'of the second rotary electric machine 300 is changed to generate a torque change of a magnitude that compensates for the change in the transmission torque Tt (S404).

Thus, without changing the driving torque of the vehicle drive shaft 910, the difference in the number of rotations between the rotors 220 and 230 can be maintained with good response by changing the current command value of the rotating electric machines 200 and 300, and the long term can be maintained. The state of power storage means 700 can be maintained at a constant level by changing the operating point of the engine. (Brake Control) Next, the brake control which is another control of the vehicle condition control will be described below. This braking control is executed by a driver's braking operation, that is, a brake pedaling operation, while the vehicle is running. Specifically, the first rotating electric machine 2
The so-called regenerative braking is performed by operating the 00 or the second rotating electric machine 300 as a generator.

More specifically, a torque command value T1 for realizing vehicle deceleration corresponding to the brake depression amount (braking amount) and the regenerative power corresponding to the vehicle speed at this time (here, the rotation speed N2 of the vehicle drive shaft 910). 'And the torque command value T2' are determined (S500). Note that the amount of regenerative power may be controlled based on the amount of storable power of power storage means 700. That is, if the rotation speed N2 of the second rotor 230 is smaller than the rotation speed N1 of the first rotor 220, the first rotor 2
The transmission torque Tt is transmitted from the motor 20 to the second rotor 230 and the torque T1 is generated in the stator 210. Therefore, the torque command value T1 ′ of the first rotary electric machine 200 is reduced to reduce the transmission torque Tt. Control to reduce the pressure. At this time, the prime mover 100 tends to increase in speed due to its own generated torque due to the reduction in the load torque.

Further, in order to operate the second rotating electric machine 300 in the synchronous generator mode, the torque command value T2 'is set and the second rotating electric machine 300 performs regenerative power generation. At this time, the power storage means 700 stores the total generated power of the reduced generated power of the first rotary electric machine 200 (attributable to the generated power of the prime mover 100) and the regenerative generated power of the second rotary electric machine 300. Is done.

On the other hand, when the rotation speed N2 of the second rotor 230 is higher than the rotation speed N1 of the first rotor 220, the transmission torque Tt is transmitted from the first rotor 220 to the second rotor 230, and In conjunction therewith, the stator 210 operates to electrically drive the first rotor 220 with the electric power P1 from the power storage means 700 (because the angular velocity of the stator current is equal to the angular velocity of the second rotor 230). 2), the torque command value T1 ′ of the first rotary electric machine 200 is increased toward the electric operation increasing side to increase the transmission torque Tt.
Increase. At the same time, the torque command value T is set so that the second rotating electric machine 300 performs the regenerative power generation operation in the synchronous generator mode.
2 ′ is set, and the second rotary electric machine 300 performs regeneration. At this time, the difference between the power transmitted to the first rotary electric machine 200 and the regenerative power generated by the second rotary electric machine 300 is stored in the power storage means 700.

When the brake pedal is operated, the accelerator pedal is returned to the depressed amount 0, so that the engine 100
Of the second rotor 230 is higher than that of the first rotor 220, and the above-mentioned state immediately appears. Therefore, the amount of power that can be generated by the second rotating electric machine 300 can be regenerated by the maximum generated power that is equal to the chargeable power of the power storage unit 700 and the electric power amount of the first rotating electric machine 200. (Large electric torque generation control as other control)
The other control of the vehicle condition control will be described below. When a large vehicle drive power demand value Pd 'is required, for example, when climbing a steep slope for a short time, the prime mover 100 is temporarily stopped and its output shaft 110 is locked by a lock mechanism 120. And the rotating electric machines 200, 300 without using the engine torque.
Can be driven electrically to drive the vehicle.
This is the same during the reverse running of the vehicle.

(Engine Control) Next, the control of the prime mover 100 with the control of the rotating electric machine performed in S108 will be described below with reference to FIG. In this control, the first rotating electric machine 200 is used as a so-called engine starter.
This is a mode in which 0 is appropriately operated and stopped.

First, it is confirmed whether or not the prime mover (engine) 100 is operating (not including the state during starting) (S6).
00), if the prime mover 100 is in operation,
Is to be stopped (S602), and if it is to be stopped, it is determined that the motor is stopped (S604). In this embodiment, the determination as to whether or not to stop is made when both the required charge / discharge power value Pb ′ of the power storage means 700 and the required vehicle drive power value Pd ′ are kept below a predetermined value for a predetermined time or more. , The engine is to be stopped.

Next, it is confirmed whether or not the engine has been stopped (S606). If not completed, the process returns to the main routine. If completed, the vehicle drive torque demand value Td 'calculated in S200 in FIG. The torque command value T1 'and the torque command value T2' are determined so as to generate (S608). However, in this case, the first rotor stationary electric drive control for maintaining the rotation speed N1 of the first rotor 220 at 0 is performed so that the stopped prime mover 100 does not rotate. This control will be described in more detail.

In this induction machine / synchronous machine, the second rotor 2
When an AC voltage is applied to the first stator 210 so that an induced voltage equal to the induced voltage generated in the first rotor 220 in the opposite direction is generated by the first rotor 220, the first rotor 22
The sum of the induced voltages within zero becomes zero, and the first rotor 22
0 can be prevented from rotating the prime mover 100.

This control is performed so that the first stator 210 torque command value T1 'becomes substantially zero.
This is equivalent to controlling the torque command value T1 'energized to zero to zero. However, the calculation in this case ignores the loss. However, the control of the torque command value T1 '= 0 is as follows.
Exactly, the exciting current that flows through the first stator 210 so that the voltage that the first stator 210 induces in the coil 222 and the voltage that the second rotor 230 induces in the coil 222 have opposite phases. This is performed by controlling.

[0108] Thus, electric traveling is performed by the second rotating electric machine 300. Therefore, the torque command value T2 '
Is determined based on the vehicle driving torque request value Td ′ and the rotation speed of the second rotor 230. On the other hand, if the prime mover 100 is not operating in S600, that is, if it is operating or starting, it is currently determined whether it is in the process of starting, that is, whether it is a period from when the start command is received to when the starting is completed. Investigation (S610), otherwise, the motor 100
Is to be started (S612), and if so, the start of the prime mover 100 is determined (S614).
The determination as to whether or not to start the engine is made when the IG switch is on and the prime mover 100 is stopped, or when it is determined that the prime mover 100 should be started based on vehicle conditions. Motor 1 according to the above vehicle conditions
00 is to be started, the charge / discharge power required value Pb ′ of the power storage means 700 or the vehicle drive power required value Pb is determined.
If the state in which both d's are equal to or more than a predetermined value continues for a predetermined time or more, an instruction to start the engine is issued.

On the other hand, if it is determined in S610 that the prime mover 100 is being started, it is checked whether or not the vehicle drive shaft 910 is locked by the lock mechanism 400 (S6).
16) If locked, a torque command value T1 'for starting the prime mover 100 is given to the first rotating electric machine 200, and a command is given to start the prime mover 100 only by the first rotating electric machine 200 (S618). . Conversely, if the motors are not locked, the torque command value T1 'and the torque command value T2' are given to the rotating electric machines 200 and 300, respectively.
0 is started (S620). That is,
In this case, the change in the transmission torque Tt due to the change in the rotation speed of the first rotary electric machine 200 is performed by the second rotor 230 so that the rotation speed N2 of the second rotor 230 does not change for the start of the prime mover 100. Control to cancel out the change in torque at 230 is performed. That is, the torque command value T2 'is changed together with the change in the torque command value T1' for starting the prime mover 100, thereby preventing a change in the torque of the vehicle drive shaft.

Thus, regardless of whether the vehicle drive shaft 910 is locked or unlocked or whether the vehicle drive shaft 910 rotates, the motor 100 can be started without affecting the rotation speed of the vehicle drive shaft 910. In addition, the engine can be stopped temporarily while the vehicle is stopped at an intersection or the like to prevent emission of exhaust gas, or the engine can be turned on and off during traveling. Note that the lock mechanism 400
May be a mechanism that can be manually operated and that automatically operates while the vehicle is stopped. (Description of Control of Motor Controller 150) An example of control of the motor controller 150 will be described below. However,
Since the control of the prime mover 100 by the prime mover controller 150 is not a main part of the present invention and is already known, a flowchart is omitted.

The prime mover controller 150 controls the prime mover 10
A vehicle drive power demand value Pv ′ to be generated to zero is received from the system controller 500, and a throttle actuator (not shown) is driven based on the input value, and based on a signal from a driving state sensor (not shown) of the prime mover mounted on the prime mover 100. By controlling the valve opening time of the fuel injection solenoid valve, the ignition timing of an ignition device (not shown) is determined and the ignition device is driven. The combustion state of the prime mover 100 is controlled by the fuel injection control and the ignition control. Further, an operating point (for example, a point C in FIG. 20) at which the vehicle drive power request value Pv ′ is output most efficiently from a motor characteristic map (see FIGS. 20 and 21) stored in a microcomputer built in the motor controller 150. Te, N
e)) is obtained, and the opening degree θTH of the throttle valve for maintaining this operating point is obtained, and this motor speed Ne is transmitted to the system controller 500 as a motor speed command value Ne ′.

As described above, the system controller 500 performs vector control to adjust the power to the first inverter 600 to the torque command value T1 ', and generates the torque generated by the prime mover 100 based on the received prime mover speed Ne. And load torque. In addition, an engine stop operation or a start operation is performed according to an input of an engine stop and start command received from the system controller 500.

(Description of Operation of Control Units 691 and 891) The control units 691 and 891 are connected to the torque command value T1 'of the first rotary electric machine 200 received from the system controller 500 through the communication terminals 6911 and 8911 and the second rotary electric machine 200. The torque command value T2 ′ of 300, the position of the first rotor 220 of the first rotating electric machine 200, the rotation speed N1, the position of the third rotor 320 of the second rotating electric machine 300, the rotation speed N2, the first rotation U-phase current iu1, W of electric machine 200

2. Based on the W-phase current iw2, a known vector control is performed to calculate an energizing current to the first rotary electric machine 200 and the second rotary electric machine 300 from the torque command value T1 ′ and the torque command value T2 ′. The rotation information N1 and N2 of the first rotary electric machine 200 and the second rotary electric machine 300 are output to the system controller 500 in accordance with the current command values i1 'and i2'.

The control units 691 and 891 are microcomputers or control circuit devices having functions equivalent to microcomputer control, and execute the rotating machine control by software or hardware. Since both have the same function, the software control will be described here. First rotating electric machine 2

4).

Next, the d-axis current command value i1d 'and the q-axis current command value i1 corresponding to the read torque command value T1'

From the torque command value T2 ', the d-axis current command value i
