In this apparatus, the speed of the output shaft of the drive motor is synchronized with the speed of the input shaft of the transmission by using a plurality of synchronization devices in the shift operation. However, the synchronization device in this device includes a hydraulic accumulator hydraulically connected with a hydraulic drive motor, for which a hydraulic circuit and a hydraulic pump are provided.

Except that the differential gear device is replaced by the planetary gear device in the embodiment shown in FIG. 5, the other matters are the same as the embodiment described in FIG. 4, and only the operation of the planetary gear device will be described below.
In the illustrated embodiment, the input shaft of the
By adjusting the gear ratio of the sun gear, the planetary gear and the ring gear, it is possible to adjust the speed ratio of the input shaft and the output shaft of the
On the other hand, the planetary gear device shown in Fig. 5 may be arranged in other ways as well. That is, one of the three gears indicated by the sun gear, the planetary gear, and the ring gear of the planetary gear unit is connected to the output shaft of the engine, one of the other two gears is connected to the motor / generator, and the other gear is connected. Can be connected to the input shaft of the transmission gear train.
Hereinafter, the case in which the synchronization device includes a differential gear device or a planetary gear device in the embodiment shown in FIG. 2 will be described with reference to the drawings.
6 and 7 respectively show a case where a differential gear or planetary gear is used as the synchronization device in the embodiment shown in FIG. Like the embodiment shown in FIG. 4, in the embodiment shown in FIG. 6, two differential gears are provided. Therefore, the differential gear device of the synchronization device is called the first differential gear device, and the differential gear device connected to the drive wheels is called the second differential gear device.
As shown in FIG. 6, the
In the shift gear train, a drive gear train is provided on the input shaft and a driven gear train is provided on the output shaft. The speed ratio of the input shaft and the output shaft is determined according to the gear ratios of the gears engaged with each other in the drive gear train and the driven gear train. Sensor devices for sensing the speed of the input shaft and the output shaft of the shift gear train are provided on the input side and the output side of the shift gear train. The
When the vehicle is driven by the driving of the engine, the power of the output shaft of the engine is directly transmitted to the shift gear train, and the output shaft of the shift gear train is connected to the input shaft of the first differential gear device of the synchronization device. While driving, the motor / generator MG1 connected to the
When the speed of the vehicle is to be shifted, the shift target is input to the controller. The shift target can be given, for example, at a predetermined speed ratio with respect to the speed of the engine output shaft. According to the shift target, the speed ratio between the input shaft and the output shaft of the shift gear train after the shift is determined, and the drive gear and the driven gear to be engaged with each other in the shift gear train are determined. The sensor device detects and transmits the speeds of the input shaft and the output shaft of the transmission gear train to the controller. Alternatively, the rotational speed of the input shaft of the transmission gear train may be calculated from the rotational speed of the engine, and the rotational speed of the output shaft from the speed of the motor / generator and the speed of the vehicle, respectively. The control unit calculates the speed of the input shaft of the shift gear train for smoothly performing the shifting operation based on the speeds of the two shafts transmitted from the sensor device and the gear ratios of the driving gear and the driven gear to be engaged. Once the target speed of the input shaft is determined, the controller drives the motor / generator device. The motor / generator device idles the second gear of the first differential gear device so that the speeds of the input and output shafts of the differential gear device are different. That is, since the rotation of the output shaft of the transmission gear train connected to the first gear of the first differential gear device is transmitted to the output shaft of the first differential gear device connected to the third gear via the second gear, when the second gear is idle, The speed of the output shaft of the gear train and the speed of the output shaft of the first differential gear device are different. When the speed of the input shaft of the first differential gear device and the output shaft of the transmission gear train directly connected thereto reaches a target value, the controller operates the shifting device (not shown) of the transmission gear train to perform the shift operation. At this time, since the speed of the output shaft of the shift gear train is synchronized with the speed of the input shaft of the shift gear train based on the gear ratio of the driving gear and the driven gear to be engaged, the shifting operation is smoothly performed without interruption using the clutch. When the shifting operation is completed, the motor / generator stops operating and the vehicle is put back into driving by the engine.
On the other hand, the motor / generator may be used as a starter motor at the start of the vehicle. When the motor / generator is activated, the second gear of the first differential gear unit rotates. In the state where the output shaft of the first differential gear device and the input shaft of the second differential gear device are connected, the third gear of the first differential gear device is not free to rotate, so that the rotation axis of the first gear, that is, the output shaft of the shift gear train rotates. The rotation of the output shaft of the transmission gear is forcibly rotated by the output shaft of the engine via the driven gear and the driving gear engaged therewith, and the engine starts.
The motor / generator can act as a generator, for example when the vehicle is driving downhill. In other words, when the motor / generator is driven downhill, the electric power can be generated using the rotation from the output shaft of the engine by switching to the generator. The generated power can be used for charging a battery (not shown).
In addition to the motor / generator connected to the second gear of the first differential gear, an auxiliary motor / generator can be arranged between the first differential gear of the synchronization device and the second differential gear of the drive wheel. The auxiliary motor / generator may be used for generating additional torque required for driving uphill or generating power for charging the battery. In addition, it is possible to directly control the deceleration / acceleration of the vehicle.
On the other hand, the first differential gear device shown in Fig. 6 may be arranged in other ways as well. That is, one of the three gears of the first differential gear device, the first gear, the second gear, and the third gear, is connected to the output shaft of the engine, and one of the other two gears is connected to the motor / generator, The other gear can be connected to the input shaft of the shifting gear train.
7 shows an embodiment in which the planetary gear device is applied instead of the first differential gear device of the synchronization device. Except that the first differential gear device is replaced by the planetary gear device in the embodiment shown in FIG. 7, the other matters are the same as the embodiment described in FIG. 6, and only the operation of the planetary gear device will be described below.
In the illustrated embodiment, the input shaft of the
By adjusting the gear ratio of the sun gear, the planetary gear and the ring gear, the speed ratio of the input shaft and the output shaft of the planetary gear device can be adjusted. That is, the first differential gear device of FIG. 6 and the planetary gear device of FIG. 7 may be designed to be mechanically equivalent. Accordingly, the shift operation or the like can be made in the same manner as described in FIG. 6.
On the other hand, the planetary gear device shown in Fig. 7 may be arranged in other ways as well. That is, one of the three gears indicated by the sun gear, the planetary gear, and the ring gear of the planetary gear unit is connected to the output shaft of the engine, one of the other two gears is connected to the motor / generator, and the other gear is connected. Can be connected to the input shaft of the transmission gear train.
Hereinafter, in the embodiment shown in FIG. 3, a case in which the synchronization device includes a double planetary / differential gear device, in particular, a case in which a dual planetary / differential gear device including two differential devices is provided will be described with reference to the drawings. . As described above, the dual planetary / differential gear unit is a combination of two planetary gear units or a differential gear unit or a planetary gear unit and one differential gear unit.
8 shows an embodiment using two differential gears as dual planetary / differential gears. The first input shaft of the dual differential gear device is connected to the output shaft of the shifting gear train using a gear, a chain or a belt, and the output shaft is connected to the rotation shaft of the driving wheel. In addition, the second input shaft of the dual differential gear unit is connected to the motor / generator. As in the above embodiment, an additional motor / generator can be provided and connected to the third input shaft of the dual differential gear device.
In the illustrated embodiment, the dual differential gear device has a structure in which a second
In the shift gear train, a drive gear train is provided on the input shaft and a driven gear train is provided on the output shaft. The speed ratio of the input shaft and the output shaft is determined according to the gear ratios of the gears engaged with each other in the drive gear train and the driven gear train. Sensor devices for sensing the speed of the input shaft and the output shaft of the shift gear train are provided on the input side and the output side of the shift gear train. The sensor device detects the speed of each axis and transmits it to the controller. As another example, the rotational speed of the input shaft of the transmission gear train may be calculated from the rotational speed of the engine and the rotational speed of the output shaft from the speed of the motor / generator and the speed of the vehicle, in which case the sensor device may be omitted. .
When the vehicle is driven by the driving of the engine, the power of the output shaft of the engine is directly transmitted to the shift gear train, and the output shaft of the shift gear train is connected to the first input shaft of the first differential gear device. While driving by the engine, the motor / generators MG1 and 220 connected to the
When shifting the traveling speed of the vehicle, the shift target is input to the controller. The shift target can be given, for example, at a predetermined speed ratio with respect to the speed of the engine output shaft. According to the shift target, the speed ratio between the input shaft and the output shaft of the shift gear train after the shift is determined, and the drive gear and the driven gear to be engaged with each other in the shift gear train are determined. The sensor device detects and transmits the speeds of the input shaft and the output shaft of the transmission gear train to the controller. Alternatively, the rotational speed of the input shaft of the transmission gear train can be calculated from the rotational speed of the engine and the rotational speed of the output shaft from the speed of the motor / generator and the speed of the vehicle, respectively. The controller calculates the speed of the output shaft of the shift gear train for smoothly performing the shifting operation based on the speeds of the two axes transmitted from the sensor device and the gear ratios of the driving gear and the driven gear to be engaged. Once the target speed of the output shaft of the transmission gear train is determined, the controller operates the motor / generator to achieve the desired speed of the transmission gear train shaft and then connects the drive gear and the driven gear. That is, when the motor / generators MG1 and 220 are operated, the
On the other hand, the motor / generator may be used as a starter motor at the start of the vehicle. When starting at stop, the engine is started by forcibly rotating the output shaft of the engine by locking the second
The motor / generator can act as a generator, for example when the vehicle is driving downhill. When slowing downhill, the running speed of the vehicle is controlled by regenerative generation by the motor / generator.
