- the shift position is the P range. In the following, it is assumed that the engine disconnecting clutch 14 is immediately engaged when the ignition switch is turned on.
- step 400 it is determined whether or not a predetermined flag has an initial value of 0. Once the flag is set to “1”, it maintains the value “1” until it is reset to the initial value 0 when the ignition switch is turned off. Immediately after the ignition switch is turned on, the value of the flag is 0. If the flag has an initial value of 0, the process proceeds to step 402. Otherwise, the process ends.

Otherwise, the process proceeds to step 412.
- step 412 it is determined whether or not the piston of the first hydraulic clutch C-1 has returned to the stroke start position. Whether the piston of the first hydraulic clutch C-1 has returned to the stroke start position may be determined by referring to a map using the oil temperature and the stroke time as parameters. In this case, for example, a stroke time with respect to the oil temperature (a time required to move from the piston stroke end position to the stroke start position) may be defined in the map based on a test, an analysis result, or the like.
- the process proceeds to step 414. If the piston of the first hydraulic clutch C-1 has not returned to the stroke start position, the process returns to step 410. In this case, the processing from Step 410 is executed again after a predetermined processing cycle.
- step 414 based on the information from the shift position sensor, it is determined whether or not the shift position has been changed from the P range to the D range or the R range. If the shift position is changed from the P range to the D range, the process proceeds to step 418. If the shift position is changed to the R range, the process proceeds to step 420. Otherwise, the process proceeds to step 416.
- step 416 it is determined whether or not a predetermined time T1 has elapsed.
- the predetermined time T1 corresponds to a time when an amount of air that can affect the response of the first hydraulic clutch C-1 starts to accumulate in the piston hydraulic chamber (and in the hydraulic line 62) of the first hydraulic clutch C-1. It may be adapted based on test results or the like. If the predetermined time T1 has elapsed, the process returns to step 402. In this case, the processing from step 402 is executed again after a predetermined processing cycle.
- the first hydraulic clutch C-1 is engaged (forms an engaged state). That is, by controlling the linear solenoid 80, the piston hydraulic chamber of the first hydraulic clutch C-1 is connected to the hydraulic line 62, and a predetermined hydraulic pressure is generated in the piston hydraulic chamber of the first hydraulic clutch C-1. At this time, preferably, in order to reduce a shock at the time of engagement, the first hydraulic clutch C-1 is shifted to the engaged state through the slip state. That is, the engagement state is formed after the slip control is performed.
- step 420 the first hydraulic clutch C-1 is released (open state is formed). At this time, if the piston of the first hydraulic clutch C-1 is moved toward the stroke start position (see step 408), such control may be continued. At this time, if the piston of the first hydraulic clutch C-1 is located at the stroke start position (see step 416), it is sufficient to maintain that state (in this case, no special control is executed). On the other hand, if the piston of the first hydraulic clutch C-1 is moved toward the end position of the piston stroke at this time (see step 402), this control is stopped and the first hydraulic clutch C-1 is released.

Abstract
Description
イグニッションオン又は車両電源オン後、パーキングレンジから走行レンジへの最初の変更が生じる前に、前記油圧式係合要素のピストン油圧室内の空気は抜けるがトルク容量が0より大きくならない態様で前記油圧式係合要素のピストン油圧室に油を供給する、制御装置が提供される。
(1)
駆動源(10、16)と駆動輪との間に設けられる油圧式係合要素(C-1)であって、イグニッションオン又は車両電源オン時に開放状態であり、パーキングレンジから走行レンジへの変更時に係合状態に移行される油圧式係合要素(C-1)を備える車両駆動装置(1)の制御装置(90)であって、
イグニッションオン又は車両電源オン後、パーキングレンジから走行レンジへの最初の変更が生じる前に、油圧式係合要素(C-1)のピストン油圧室内の空気は抜けるがトルク容量が0より大きくならない態様で油圧式係合要素(C-1)のピストン油圧室に油を供給する、制御装置(90)。
(2)
ピストン油圧室に油を供給した後、パーキングレンジから走行レンジへの最初の変更が生じるまで、供給した油をピストン油圧室から抜くこと、及び、ピストン油圧室に油を供給することを繰り返す、(1)に記載の制御装置(90)。
(3)
ピストン油圧室に油を供給するときの油圧指令値の大きさは、パーキングレンジから走行レンジへの最初の変更が生じたときの油圧指令値の初期値の大きさと同じである、(2)に記載の制御装置(90)。
(4)
ピストン油圧室に油を供給した後、パーキングレンジから走行レンジへの最初の変更が生じるまで、更にピストン油圧室に油を供給し続ける、(1)に記載の制御装置(90)。
(5)
ピストン油圧室に油を供給し続けることは、ピストン油圧室に油を供給した後のピストンストロークを維持する態様で、実行される、(4)に記載の制御装置(90)。
(6)
イグニッションオン又は車両電源オン後、パーキングレンジから走行レンジへの最初の変更が生じた場合に、油圧式係合要素(C-1)をスリップ状態を経て係合状態に移行させる、(1)~(5)のうちのいずれかに記載の制御装置(90)。
