SUMMARY OF THE INVENTION In the above hybrid vehicle, during a shift change, the difference in the number of revolutions between the input side (clutch device side) and the output side (driving wheel side) is incorporated in a manual transmission. The input side and the output side of the manual transmission are connected in synchronization with each other by a mesh mechanism.

Usually, the time (synchronization time) required for synchronizing the rotation on the input side and the rotation on the output side by the synchromesh mechanism is substantially proportional to the moment of inertia on the input side of the synchromesh mechanism, and Is almost inversely proportional to the torque generated. Accordingly, in the configuration in which the motor generator is connected between the clutch device and the manual transmission, the moment of inertia on the input side of the synchromesh mechanism is larger than that of the vehicle without the motor generator, and therefore the motor generator is In order to obtain the same synchronization time as that of a car that does not have it, it is necessary to increase the load on the synchromesh mechanism.

The shift speed detecting means detects the shift speed of the manual transmission before the shift and the target shift speed in the shift speed changing means. The rotation speed detection means detects the rotation speed of the manual transmission. The rotation speed calculation means is based on the shift speed and the target shift speed before the shift detected by the shift detection means and the rotation speed before the shift of the manual transmission, and the target rotation speed of the manual transmission at the target shift speed. Is calculated. The rotation speed adjusting means operates the motor generator as a motor or a generator to adjust the rotation speed of the manual transmission to the target rotation speed.

In this shift control device for a hybrid vehicle, the manual transmission at the target shift speed is determined based on the shift speed of the manual transmission before shift, the target shift speed, and the rotation speed of the manual transmission before shift. The target rotation speed is calculated, and the motor / generator connected to the input side of the manual transmission is caused to function as a motor or a generator to adjust the rotation speed of the manual transmission to the target rotation speed, and then the gear is changed. For example, in the case of upshifting, it is necessary to make the target rotation speed smaller than the rotation speed before the shift, and therefore the motor generator is caused to function as a generator and the rotation speed is adjusted so as to be lowered. On the other hand, in the case of downshifting, it is necessary to make the target rotation speed higher than the rotation speed before the shift, and therefore the motor generator is adjusted to function as a motor to increase the rotation speed.

In such a hybrid vehicle, the vehicle is driven by the driving force of the engine 1, and the motor generator 7 regenerates the driving force of the engine 1 as braking energy to store electricity in the battery 10 when necessary. In addition, it is possible to travel while assisting the driving force of the engine 1 by converting the electricity stored in the battery 10 into the driving force.

(2) Structure of Shift Control Device The hybrid vehicle of this embodiment further includes a shift control device 20 for synchronizing the rotation speeds of the input shaft 8 and the output shaft 9 of the transmission 4. Specifically, the gear shift control device 20 synchronizes the rotation speeds of the input shaft 8 and the output shaft 9 by the synchromesh mechanism 4a of the conventional transmission 4 prior to the synchronization.
The motor generator 7 connected to the input shaft 8 is used to perform control for synchronizing the rotation speeds of the input shaft 8 and the output shaft 9.

The shift control device 20 includes the clutch connecting / disconnecting means 12, the clutch connecting / disconnecting detecting means 14 for detecting the connecting / disconnecting state of the clutch device 6, the shift speed changing means 13, and the shift speed changing. A shift speed detecting means 15 for detecting the shift speed C _i and the target shift speed C _j before shifting of the transmission 4 in the means 13, and a rotation speed detecting means 16 for detecting the rotation speed of the transmission 4. A rotation speed calculation means 17 for calculating a target rotation speed N _j of the transmission 4 at the target shift speed,
And a rotation speed adjusting means 18 for adjusting the rotation speed of the transmission 4 to the target rotation speed N _j .

As shown in FIG. 3, the gear position detecting means 15 is a position sensor installed corresponding to each of the five gear positions except the reverse gear R from the neutral position N, more specifically, the neutral position. It is arranged at the gate entrance from each position to each gear, that is, at a position on the stroke before entering each gear. That is, the shift speed C _i before the shift is the shift speed detected by the position sensor when the shift lever of the shift speed changing means 13 is pulled out to move to the neutral position N from the state of traveling at a certain shift speed. Say. Further, the target shift speed C _j means a shift speed detected by the position sensor when the shift lever is inserted into another shift speed (including the same shift speed) after detecting the shift speed C _i before the shift. .

The rotation speed detecting means 16 is, in this embodiment,
It is a rotation sensor for measuring the rotation speed of the input shaft 8 of the transmission 4. The rotation speed calculation means 17 includes a gear position detection means 15
Based on the measured data of the shift speed C _i and the target shift speed C _j before shift and the rotation speed N _i of the transmission 4 before shift detected by the above, the target rotation speed of the transmission 4 suitable for the target shift speed C _j. N _j
For calculating. Here, the target rotation speed N _j
Is calculated by multiplying the rotational speed N _i of pre-shift to the ratio α _j / α _j of the gear ratio alpha _j of the target gear C _j for gear ratio alpha _i gear C _i before shifting.

The rotation speed adjusting means 18 causes the motor generator 7 to function as a motor or a generator so that the rotation speed N _i of the input shaft 8 of the transmission 4 before shifting is calculated as the target rotation speed calculated by the rotation speed calculating means 17. It is a controller for adjusting (synchronous control) so that the number becomes N _j .
Specifically, in the case of an upshift, the calculated target rotation speed N _j becomes lower than the rotation speed N _i before shifting, so the rotation speed adjusting means 18 causes the motor generator 7 to function as a generator. Rotational speed control is performed in the direction of decreasing the rotational speed of 8. In the case of a downshift, the calculated target rotation speed N _j becomes higher than the rotation speed N _i before the shift, so that the rotation speed adjusting means 18 causes the motor generator 7 to operate.
Is operated as a motor to control the rotation speed in the direction of increasing the rotation speed of the input shaft 8.

Further, the rotation speed adjusting means 18 is required to operate the shift speed changing means 15, that is, the time until a shift command from the shift speed C _i before shifting to the target shift speed C _j is issued (hereinafter , The switching command time Δt)
It is possible to change the rate of change of the rotation speed of the input shaft 8 due to the input / output of torque from the motor generator 7 to the transmission 4. In the present embodiment, the rotation speed adjusting means 18 adjusts the rotation speed N _i before the shift to the target rotation speed N _j as quickly as possible because the time Δt becomes short when the driver performs the shift operation quickly. The change rate of the rotational speed is set to be large so that it can be performed. On the contrary, when the driver's shift operation is performed slowly, the time Δt becomes long, so that the rotation speed N _i before the shift can be adjusted to the target rotation speed N _j as slowly as possible. We try to reduce the rate of change of numbers.

(3) Operation of Shift Control Device for Hybrid Vehicle Next, the operation of the shift control device 20 for a hybrid vehicle will be described. Here, FIG. 4 is a flowchart showing the shift control of the hybrid vehicle, and FIG. 5 is a flowchart showing the synchronous control of the shift control. In the clutch disengagement steps S1 and S2, in step S1, the driver operates the clutch engagement / disengagement means 12 to connect the clutch device 6 and the flywheel 2 prior to shifting the speed of the hybrid vehicle running at the shift speed C _i. The clutch connection / disconnection detection means 14 detects the state of disconnection. At this time, the clutch device 6 and the flywheel 2 are disengaged, so that the transmission 4 receives no torque from the engine 1.

In step S2, after it is detected in step S1 that the clutch device 6 is in the disengaged state, the energization between the motor generator 7 and the battery 10 is disengaged (motor generator OFF). As a result, the motor generator 7 is in a state of being rotated around the input shaft 8. Shift command steps S3 to S6 Steps S3 to S6 are steps for operating the shift lever of the shift speed changing means 13 to issue a command to shift from the shift speed C _i to the target shift speed C _j .

Specifically, when the shift lever of the gear change means 13 is pulled out from the state of the gear C _i to the neutral state N (step S3), the gear is set at the stroke position immediately after the gear shifts out of the gear C _i . The gear shift detecting means 15 detects the gear shift C _i and its time t _i . The data of the detected shift speed C _i and time t _i are output to the rotation speed calculation means 17 (step S4). Next, when the shift lever of the shift speed changing means 13 is further operated to enter the target shift speed C _j (step S5), the shift speed detecting means 15 installed at the stroke position immediately before the target shift speed C _j. The target gear C _j and the time t _j are detected by. And data of the target shift stage C _j and time t _j, the rotation of the target gear C _j is the rotational speed N _i of the input shaft 8 which is measured by the rotation speed detecting means 16 when it is detected (pre-shift gear The data of (number) is input to the rotation speed calculation means 17 (step S6).

Synchronous control step S7 (S71 to S7)
3) The synchronous control step S7 mainly includes the target rotation speed N _j based on the shift speed C _i before the shift, the target shift speed C _j, and the rotation speed N _i.
A rotation speed calculation step S71 for calculating, and causing the motor generator 7 to function as a motor or a generator,
And a rotational speed adjusting step S72 for adjusting the rotational speed of the transmission 4 to the target rotational speed N _j .

In the rotation speed calculation step S71, the rotation speed calculation means 17 calculates the target rotation speed N _j on the basis of the shift speed C _i before shifting, the target shift speed C _j and the rotation speed N _i, and further,
The time t _i at which the shift speed C _i before shifting is detected and the target shift speed C _i
Based on the time t _j at which _j is detected, the switching command time Δ
Calculate t. Then, the calculated target rotation speed N _j and the switching instruction time Δt are output to the rotation speed adjusting means 18.

In the rotation speed adjusting step S72, the rotation speed is adjusted.
The node means 18 connects the motor generator 7 to a motor or a generator.
The speed of the transmission 4 is changed to the target rotation by operating as a speed controller.
Number N _jAdjust so that Specifically, the target speed
N_jIs the rotation speed N before shifting_iGreater than (down shift
Motor generator 7 as a motor.
To control the rotation speed, and conversely, the target rotation speed N_jStrange
Speed N immediately before_iLess than (upshift method
Direction), the motor generator 7 as a generator
Function to control the rotation speed. The rotation speed adjusting means 18
Is a switching command input from the rotation speed calculation means 17.
The rate of change of the rotational speed during control is changed according to the interval Δt.
It is possible to change the speed of the driver.
The rotation speed of the input shaft 8 is adjusted according to the operation speed. So
Then, the rotation speed of the input shaft 8 is equal to the target rotation speed N._jAfter reaching
(Step S73), the process proceeds to the next step.

After changing the number of revolutions of the input shaft 8 to the target number of revolutions N _j , the power generation between the motor generator 7 and the battery 10 is turned off (motor generator OFF) (step S8). . After that, the gear of the transmission 4 is changed to the gear corresponding to the target shift speed C _j (step S9). At this time, since the rotation speeds of the input shaft 8 and the output shaft 9 are synchronized around the target rotation speed N _j , smooth gear shifting is performed.

Clutch engagement step S10 After the gear shift steps S8 and S9, the clutch connecting / disconnecting means 12 is operated to connect the clutch device 6 to the flywheel 2 to connect the engine 1 and the transmission 4. (4) Features of Shift Control Method and Shift Control Device Features of the shift control method and shift control device 20 for the hybrid vehicle of the present embodiment will be described.

Synchronous control at the time of gear shift by the motor generator In the gear shift control method of the hybrid vehicle of the present embodiment,
The target rotation speed N of the transmission 4 at the target shift speed C _j is determined based on the shift speed C _i of the transmission 4 before the shift, the target shift speed C _j, and the rotation speed N _i of the transmission 4 before the shift. _j is calculated, and the motor generator 7 connected to the input side of the transmission 4 is caused to function as a motor or a generator to adjust the rotation speed of the transmission 4 to the target rotation speed N _j , and then shift. .

As a result, after the rotation speeds of the input shaft 8 and the output shaft 9 of the transmission 4 are synchronized by the shift command, it is possible to switch to the target shift speed C _j , which enables smooth switching operation. At the same time, it is possible to prevent gear squeal caused by contact between the gear of the synchromesh mechanism 4a and the hub sleeve at different rotational speeds. In addition, in the hybrid vehicle of the present embodiment, the inertia moment on the input shaft 8 side is large due to the presence of the motor generator, but the above-described synchronous control of the input shaft 8 and the output shaft 9 by the motor generator 7 is performed. Therefore, the load on the synchromesh mechanism 4a of the transmission 4 can be reduced.

Further, in the shift control method for the hybrid vehicle of this embodiment, when the clutch device 6 is disengaged, the motor generator 7 is temporarily turned off. Therefore, the transmission is executed in the shift command steps S3 to S6. The operation when pulling out the No. 4 gear is smooth. Calculation of Target Rotation Speed In the shift control device 20 for a hybrid vehicle according to the present embodiment, the target rotation speed N _j is the shift speed C _i before shifting, the target shift speed C _j, and the rotation speed N _i of the transmission 4 before shifting. Since the calculation is performed based only on the measurement data, the number of parameters used for the calculation and the number of detecting means are small, and the calculation is easy.

Detecting Positions of Gear Stage and Target Gear Stage Before Change During Shift Operation In the gear shift control device 20 of the hybrid vehicle of the present embodiment, the gear position detecting means 15 is the neutral position N of the shift lever of the gear position changing means 13. Since it is arranged on the stroke of each shift speed, the shift speed can be detected in response to various shift operations on the command side (driver side).

Synchronous control according to driver's shift operation speed In the shift control method of the hybrid vehicle of the present embodiment,
Gear shift stage C before gear shift in gear shift command steps S3 to S6
_Since the change rate of the rotational speed when the torque is input / output from the motor generator 7 to the transmission 4 is made variable in accordance with the switching command time Δt from issuing the switching command from _i to the target shift stage C _j . The rotation speed can be adjusted in consideration of the operation speed on the command side (driver side).
