Definitions
- the clutch K0 is drivingly connected to a clutch input shaft 31, which is an example of an engine connecting member drivingly connected to the output shaft 21 of the engine 2, and a clutch output shaft 32 drivingly connected to the rotor shaft 41 of the motor 4. It is interposed between the input shaft 31 and the clutch output shaft 32 and enables power transmission between the clutch input shaft 31 and the clutch output shaft 32 by frictional engagement.
- the engagement state of the clutch K0 is freely controlled according to the clutch oil pressure supplied from the hydraulic control device (V/B) 6 based on the command from the ECU 7, and the torque capacity thereof is also freely controlled.
- the motor 4 is connected to the battery 83 via the inverter 82 .
- electric power output from the battery 83 is supplied to the motor 4 via the inverter 82 to drive the motor 4 .
- the ECU 7 determines to end the differential rotation speed reduction control (YES in step S10), it ends the differential rotation speed reduction control and switches to torque control (t6, step S11). Further, the ECU 7 increases the engagement pressure of the clutch WSC by increasing the required torque of the clutch WSC, and switches from the engagement preparation phase to the actual engagement phase (t6, step S11). The required torque of the clutch WSC is 0 Nm until t6, and increases in a sweeping manner from t6. As a result, the clutch WSC is provided with a torque capacity to reduce the differential rotation speed.
- the ECU 7 determines to end the rotation speed control of the motor 4 (YES in step S8), it starts rotation speed control to reduce the differential rotation speed (step S9).
- the ECU 7 gradually reduces the differential rotation speed until it reaches the fourth set value (t15-t16). That is, during execution of the engagement preparation phase, when the hybrid vehicle 100 is in a decelerating state, the ECU 7 increases the differential rotation speed from the rotation speed of the input shaft 51 after the differential rotation speed reaches the second set value. is controlled to decrease at a predetermined gradient so as to become a fourth set value that is lower than the second set value and has a smaller absolute value than the second set value. Since the engine torque decreases from this time point (t15), the engagement pressure of the clutch K0 is decreased. Also, the fourth set value may be the same as or different from the third set value.
- This vehicle driving device (3) is a rotating electric machine (4); interposed between the rotating electrical machine (4) and a transmission member (51) drivingly connected to one of the front wheel (11) and the rear wheel (12), and the rotating electrical machine (4) a first clutch (WSC) capable of connecting and disconnecting power transmission with the transmission member (51);
- the control device (7) is Engagement control for changing the first clutch (WSC) from the released state to the fully engaged state after determining the engagement when the first clutch (WSC) is in the released state,
- the ECU 7 executes an engagement preparation phase in which torque capacity is not generated in engagement control and an actual engagement phase in which torque capacity is generated and reaches a complete engagement state.
- an engagement preparation phase in which torque capacity is not generated in engagement control
- an actual engagement phase in which torque capacity is generated and reaches a complete engagement state.
- hybrid drive system 3 of the present embodiment has been described as having the speed change mechanism 5, but the present invention is not limited to this, and instead of the speed change mechanism 5, a power transmission mechanism that does not shift gears may be applied. may
