FIG. 7 is a torque diagram during normal running in the embodiment.

In this embodiment, as shown in FIG. 3, the number of teeth of the ring gear R of the planetary gear unit 13 (FIG. 2) is twice the number of teeth of the sun gear S. Therefore, the torque output to the output shaft 14 (hereinafter referred to as “output torque”) is defined as TOUT, and the torque of the internal combustion engine 11 (hereinafter referred to as “engine torque”) is defined as TE.
When the torque of the generator motor 16 (hereinafter referred to as “generator motor torque”) is TG, TE: TOUT: TG = 3: 2: 1, and the reaction forces are received.

Next, the driving force will be described.

FIG. 5 is a diagram showing the relationship between the vehicle speed and the driving force in the first embodiment of the present invention. In the drawing, the horizontal axis represents the vehicle speed V, and the vertical axis represents the driving force.

When the driving force of the hybrid vehicle is Q, the torque is T _W , the gear ratio is r, and the radius of the tire of the driving wheel is R, the driving force Q is: Q = T _W · r / R can be represented by

The driving force required to drive the hybrid vehicle (hereinafter referred to as "required driving force") is Q.
1, the driving force of the electric motor 25 (FIG. 2) is QM,
The driving force of the generator motor 16 is QG, and the internal combustion engine 1
Assuming that the first driving force is QE, the driving force QM is smaller than the necessary driving force Q1, and the hybrid vehicle cannot travel with the driving force QM alone.

Therefore, the insufficient driving force is applied to the internal combustion engine 1.
1 or the generator motor 16, but generally, the driving force QG of the generator motor 16 increases as the vehicle speed V decreases. For example, when the vehicle speed V is lower than 30 [km / h], the driving force QG of the generator motor 16 becomes larger than the driving force QE of the internal combustion engine 11.

Therefore, in the present embodiment, when the vehicle speed V is lower than 30 [km / h], the internal combustion engine 1
1 is stopped, the driving force QG of the generator motor 16 compensates for the shortage of the driving force QM, and the vehicle speed V becomes 30 [km / h].
In the case described above, the shortage of the driving force QM is compensated for by the driving force QE of the internal combustion engine 11.

Thus, the driving force QM of the electric motor 25 can be reduced in the low speed range. Therefore, the torque constant of the electric motor 25 can be reduced accordingly, and the size of the electric motor 25 does not increase.

When the internal combustion engine 11 is stopped and the hybrid vehicle is driven in the motor drive mode,
In a region where the load applied to the electric motor 25 is small (hereinafter, referred to as a “low load region”), the efficiency of the hybrid vehicle generally decreases. Therefore, the vehicle speed V is 30 [km /
h] The hybrid vehicle is driven by the driving force QG of the generator motor 16 in a lower low load region and by the driving force QM of the electric motor 25 in a high load region.

Step S1 The CPU 51 (FIG. 1) reads the detected vehicle speed V and accelerator opening α. Step S2: It is determined whether the necessary driving force Q1 (FIG. 5) is large and the accelerator opening α is larger than 80%. If the accelerator opening α is greater than 80%, the process proceeds to step S3, and if the accelerator opening α is 80% or less, the process returns. Step S3: The vehicle speed V is a set value, for example, 30 [km /
h]. Vehicle speed V is 30 km
/ H], the process proceeds to step S4, and the vehicle speed V becomes 3
If it is 0 [km / h] or more, the routine returns. Step S4: The internal combustion engine 11 is stopped. Step S5: Current IM supplied to generator motor 16
To the maximum value IMmax. Step S6 The generator motor drive processing is performed by the generator motor controller 47, and the driving force QG of the generator motor 16 is
This compensates for the shortage of the driving force QM of the electric motor 25.

When the vehicle speed V is higher than [%] and the vehicle speed V is lower than 30 [km / h], the internal combustion engine 11 is stopped, the brake B is engaged, and the current IM supplied to the electric motor 25 is set to the maximum value. Set to IMmax.

Next, a third embodiment of the present invention will be described. In addition, about what has the same structure as 1st Embodiment, the description is abbreviate | omitted by attaching the same code | symbol.

In this case, the driving force QG of the generator motor 16
Although the shortage of the driving force QM of the electric motor 25 is compensated by (FIG. 5), the clutch C is released during this time, so that there is no need to stop the internal combustion engine 11.

Next, a fourth embodiment of the present invention will be described.

In the figure, 11 is an internal combustion engine, 12 is an output shaft, and a generator motor 66 as an electric machine is connected to the output shaft 12. A one-way clutch F as a braking means is provided between the output shaft 12 and the casing 19.

The generator motor 66 comprises a rotor 71 rotatably disposed, a stator 72 rotatably disposed around the rotor 71, and a coil 73 wound around the stator 72. The generator motor 66
Generates electric power by rotation transmitted through the output shaft 12. The coil 73 is connected to a battery 43 (FIG. 1), and a current is supplied to the battery 43 to be charged.

The internal combustion engine and the electric machine constitute a countershaft in which the electric motor is arranged on a first axis, the electric motor is arranged on a second axis, and the output shaft is arranged on a third axis.

In this case, the third gear element generates a reaction force by a one-way clutch which is a mechanical braking means. Then, the electric machine device used as a generator can be used as a motor. Therefore, since the driving force of the electric device can be added to the running torque of the hybrid vehicle, the driving force of the electric motor can be reduced by the driving force of the electric device.

As a result, the torque constant of the electric motor can be reduced correspondingly, so that the electric motor does not increase in size, does not require a large-capacity inverter element, and can be used in a hybrid type in a high load region. The vehicle can run.

Then, the internal combustion engine, the electric machine and the electric motor constitute a countershaft in which the output shaft is arranged on a second axis and the output shaft is arranged on a second axis.

In this case, since the hybrid vehicle can be driven by the driving force of the electric device, the driving force of the electric motor can be reduced by the driving force of the electric device.

Therefore, the torque constant of the electric motor can be reduced accordingly, and the size of the electric motor does not increase.
