  • Patent number: 9815455
    Abstract: A control device for a vehicle drive device having a speed change mechanism that attains a predetermined shift speed by engaging multiple engagement elements. The control device predicts an amount of heat generation and determines whether any jumping shift from the current shift speed to the shift speed that is the multiple shift speeds higher or lower than the current shift speed can be permitted or not between the current shift speed and the target shift speed, and if the jumping shift can be permitted, the control unit performs the jumping shift and controls the speed change mechanism so as to shift the shift speed from the current shift speed to the target shift speed.

  • Patent number: 9567964
    Abstract: A control device that controls a vehicle drive device. A starting control section executes internal combustion engine starting control in which the internal combustion engine in a stationary state is started while causing the disconnecting engagement device to transition from a disengaged state to a direct engagement state. A timing decision section that decides, on the basis of a rotational speed of the internal combustion engine, a supply start timing to start supply of a hydraulic pressure to a specific engagement device, which is one of the plurality of shifting engagement devices and is caused to transition from a disengaged state to a direct engagement state in order to establish a target shift speed for the speed change mechanism after a change, in the case where the target shift speed is changed during execution of the internal combustion engine starting control.

  • Patent number: 9457801
    Abstract: A control device for a hybrid vehicle for use in a hybrid vehicle in which a first clutch, a rotary electric machine, and a second clutch are disposed on a power transfer path from an engine to wheels sequentially from the engine side. After power generation control in which the engine is driven with the first clutch directly engaged and with the second clutch disengaged is suspended on the basis of detection of the starting request from a state in which the vehicle is stationary with the power generation control performed, the second clutch control means controls the second clutch from a disengaged state to a slip engagement state, the first clutch control means controls the first clutch from an engaged state to a slip engagement state, and the rotary electric machine control means reduces the target revolving speed.

  • Patent number: 9303758
    Abstract: A control device configured to control a vehicle. When the required driving force is equal to or less than a control judgment value, the shift control section judges that an implementing condition of engagement limited downshift control is met, starts transition control to cause the release-side engagement device to transition to a non-direct-coupled engagement state and, after the release-side engagement device transitions to a non-direct-coupled engagement state, starts increasing rotation speed control to control rotation speed of the input member to be higher than synchronized rotation speed, starts differential rotation speed control to control the rotation speed to be higher than the synchronized rotation speed, and prohibits engagement of the engagement-side engagement device until it becomes higher than the synchronized rotation speed.

  • Patent number: 9216734
    Abstract: A control device for a vehicle. A shift assist control section executes shift assist control of increasing a rotational speed of an input-side rotating member of the speed change mechanism. A possibility determining section that determines whether or not the rotating electrical machine can output required input torque. A mode selecting section that selects one shift mode from a first shift mode and a second shift mode that is different from the first shift mode in at least one of a condition for starting the downshift and processing. A torque compensating section that, if it is determined that the rotating electrical machine cannot output the required input torque, compensates for a shortfall in the required input torque in the shift assist control by using at least one of output torque of the internal combustion engine and torque that is transferred by the shift engagement device according to the shift mode.
