Definitions
- the present invention relates to a control device for a vehicle drive device suitably used for a hybrid vehicle, and more particularly to control of a clutch interposed between an engine and a manual transmission.
- An engine and an electric motor which are driving power sources for traveling, a manual transmission that receives the power of the engine via the clutch and outputs the power to the drive wheels, and a release cylinder that releases the clutch in accordance with the supplied hydraulic pressure; 2.
- a control device for a vehicle drive device that includes a master cylinder that supplies hydraulic pressure to a release cylinder by depressing a clutch pedal.
- the vehicle drive control device of Patent Document 1 is an example.
- the vehicle of Patent Document 1 includes a hydraulic pressure supply source configured to include an oil pump and a solenoid valve.
- the release cylinder is supplied with hydraulic pressure from the hydraulic supply source separately from the master cylinder.
- the drive control device can automatically release the clutch and disconnect the engine from the drive wheel by supplying hydraulic pressure from the hydraulic pressure supply source to the release cylinder.

For example, the stop determination vehicle speed V0 is greater than zero and substantially zero. The vehicle speed is V.
- the stop determination vehicle speed V0 may be zero, and if so, the stop determination unit 110 determines whether or not the driver has stopped the vehicle 8.
- the clutch release state determining means 112 sequentially determines whether or not the clutch 14 is completely released, that is, whether or not the clutch 14 is in a fully released state. Specifically, the clutch disengagement state determination means 112 determines the stroke amount STKrc (hereinafter referred to as “the clutch release state”) from the predetermined reference stroke position in the clutch release cylinder 64 when the shut valve 80 is fully open. It is determined whether or not the release cylinder stroke amount STKrc) exceeds a predetermined stroke amount determination value STK1rc.

Therefore, when the charge state determination unit 120 determines that the remaining charge SOC is less than the remaining charge lower limit LOsoc, the vehicle start travel control unit 122 determines that the accelerator pedal 95 is stopped while the engine 12 is stopped. When the stepping-in operation is performed, the starter motor 51 cranks the engine 12 to start (activate) it. Then, after the engine is started, the vehicle 8 is started in the HV traveling according to the accelerator opening Acc, and the HV traveling is performed.

Then, it is sequentially determined whether or not the input shaft rotation speed Nin is equal to or higher than a predetermined engine start rotation speed Nste. As a result of the determination, when the input shaft rotational speed Nin becomes equal to or higher than the engine start rotational speed Nste, the traveling state of the vehicle 8 is switched from the EV traveling to the HV traveling. For this switching, the vehicle start travel control means 122 executes engine start control for starting the engine 12 during the EV travel.

Since the engine is started in the engine start control as described above, the vehicle start travel control means 122 sets the shut valve 80 to slip the clutch 14 when starting the engine 12 during the EV travel. It can be said that it opens.
