For example, the lockup clutch 3a is released during start acceleration and during steady driving or deceleration driving. For example, the lockup clutch 3a is engaged.
- the forward clutch 4 is located between the torque converter 3 and the CVT 5, and is engaged when the drive torque from the internal combustion engine 1 can be transmitted to the drive wheels 7. That is, the forward clutch 4 is arranged on the power transmission path that transmits the driving force of the internal combustion engine 1 to the drive wheels 7. The operation of engaging / disengaging the lockup clutch 3 and the forward clutch 4 is performed based on a control command from the control unit 21 described later.
- the CVT 5 has a primary pulley 8 on the input side, a secondary pulley 9 on the output side, and a belt 10 that transmits the rotation of the primary pulley 8 to the secondary pulley 9.

- the speed of the vehicle is equal to or less than the speed threshold value V0 at time t1.
- the regeneration execution flag is switched from “1” to “0” at time t1.
- the alternator 11 performs regenerative power generation when the regenerative execution flag is "1", and does not perform regenerative power generation when the regenerative execution flag is "0". Therefore, the alternator 11 ends the regenerative power generation at the timing when the regenerative execution flag is switched from “1” to "0", and starts the regenerative power generation at the timing when the regenerative execution flag is switched from "0" to "1".
- the regenerative power generation performed by the alternator 11 is stopped when the vehicle speed becomes equal to or lower than the speed threshold V0, which is a predetermined constant value, the regenerative power generation of the alternator 11 is stopped and locked depending on the deceleration of the vehicle.

- the control unit 21 of this embodiment releases the lockup clutch 3a when the vehicle speed becomes equal to or less than the first speed threshold value V1 during deceleration running. Further, the control unit 21 stops the regenerative power generation performed by the alternator 11 when the vehicle speed becomes equal to or less than the second speed threshold value V2, which is different from the first speed threshold value V1 during deceleration (the first speed threshold value V1 and the second speed threshold value V2 are: Always different regardless of conditions).
- the first speed threshold value V1 corresponds to the first vehicle speed and changes according to the deceleration of the vehicle.
- the second speed threshold value V2 corresponds to the second vehicle speed and changes according to the deceleration of the vehicle.

- FIG. 3 is a timing chart showing an example of operation when the first speed threshold value V1 and the second speed threshold value V2 are set according to the deceleration of the vehicle.
- the first speed threshold value V1 shown by the broken line in FIG. 3 is set to a value different from the second speed threshold value V2 shown by the broken line in FIG. That is, the first speed threshold value V1 and the second speed threshold value V2 are set so as to have different values when the deceleration of the vehicle is the same.
- the vehicle speed shown by the solid line in FIG. 3 becomes the second speed threshold value V2 or less at the timing of time t1, and the regeneration execution flag is switched from "1" to "0" at time t1.
- the vehicle speed shown by the solid line in FIG. 3 becomes equal to or less than the first speed threshold value V1 at the timing of time t2, and the lockup signal is switched from “ON” to “OFF” at time t2. ..
- the threshold value when the lockup signal is switched from “OFF” to “ON” is set to a value larger than the first speed threshold value V1. Therefore, in FIG. 3, the lockup signal is maintained in the “OFF” state even after the time t2.
- the control unit 21 may be controlled so that the regenerative power generation of the alternator 11 ends earlier than the release of the lockup clutch 3a. That is, the first speed threshold value V1 may be set to be smaller than the second speed threshold value V2.
- the regenerative power generation of the alternator 11 can be terminated before the lockup clutch 3a is released, and the timings of stopping the regenerative power generation of the alternator 11 and releasing the lockup clutch 3a do not overlap. , Deterioration of driving performance can be suppressed.
- the control unit 21 may be controlled so that the lockup clutch 3a is released earlier than the end of the regenerative power generation of the alternator 11. That is, the first speed threshold value V1 may be set to be larger than the second speed threshold value V2.
- the second speed threshold value V2 for terminating the regenerative power generation of the alternator 11 can be set low for the purpose of improving fuel efficiency.
- the first speed threshold value V1 and the second speed threshold value V2 may be set so as to increase as the refrigerant pressure of the air conditioner increases.
- the load of the internal combustion engine 1 increases as the refrigerant pressure of the air conditioner increases.
- the first speed threshold value V1 and the second speed threshold value V2 may be changed depending on whether the brake is on or off.
- the deceleration is changed to reflect the driver's will, so even if the first speed threshold value V1 and the second speed threshold value V2 are set to be lower than in the case of brake off.
- Driving performance can be ensured without giving the driver a sense of discomfort.
- the first speed threshold value V1 and the second speed threshold value V2 are set to be higher than in the case of brake on, and the change in deceleration is reduced to prevent the driver from feeling uncomfortable. This ensures driving performance.

- step S3 it is determined whether or not the vehicle speed is equal to or less than the second speed threshold value V2. If the vehicle speed is equal to or less than the second speed threshold value V2 in step S3, the process proceeds from step S3 to step S4. If the vehicle speed is not equal to or less than the second speed threshold value V2 in step S3, the process proceeds from step S3 to step S5.
- step S4 the regenerative power generation of the alternator 11 is terminated.
- step S5 it is determined whether or not the lockup is being performed, that is, whether or not the lockup clutch 3a is engaged. If the lockup clutch 3a is released in step S5, the process proceeds from step S5 to step S4. If the lockup clutch 3a is engaged in step S5, the process proceeds from step S5 to step S6.
- step S6 it is determined whether or not the fuel cut of the internal combustion engine 1 is implemented. If the fuel cut is not performed in step S6, the process proceeds to step S4. If the fuel is cut in step S6, the process proceeds to step S2.
