Abstract: A control system for preventing engine stall due to slippage of a wheel during propulsion in a fixed mode in which an engine and the wheel are rotated at a fixed ratio. When a wheel slips in a first mode in which an engine and the wheel are rotated at a predetermined ratio, an operating mode is shifted to a second mode in which a torque transmission between the engine and the wheel is interrupted and the vehicle is propelled by torque of driving machine connected to the wheel, or to a third mode in which the vehicle is propelled by delivering torque of the engine to the wheel while establishing a reaction torque by a predetermined rotary member.

Abstract: There are provided a controller and a control method for a hybrid vehicle including an engine with a supercharger serving as a drive power source for travel, a rotary machine serving as a drive power source for travel, and a power storage device configured to transmit and receive electric power to and from the rotary machine. The controller determines whether an operation of the supercharger is limited, compensates for a torque shortage of the engine due to limitation of the operation of the supercharger by a torque of the rotary machine when it is determined that the operation of the supercharger is limited, and curbs a decrease in an amount of electric power stored in the power storage device more when it is determined that the operation of the supercharger is limited than when it is determined that the operation of the supercharger is not limited.

Abstract: A control apparatus for a vehicular power transmitting system includes a power transmission switching portion configured to selectively establish a first drive mode by placing one of the first and second coupling elements in an engaged state, a second drive mode by placing the other of the first and second coupling elements in an engaged state, or a third drive mode by placing both of the first and second coupling elements in the engaged states. The power transmission switching portion switches the vehicular power transmitting system between the first and second drive modes through the third drive mode, where a predetermined condition is not satisfied, and switches the vehicular power transmitting system between the first and second drive modes with concurrent engaging and releasing actions of the first and second coupling elements, where the predetermined condition is satisfied.

Abstract: A control system controls a power transmission system located between a motive power source and drive wheels. The power transmission system includes a fluid coupling and an engagement device. The control system includes an electronic control unit configured to: obtain information concerning vibration of the power transmission system; determine whether the vibration of the power transmission system is in a resonance region of the power transmission system; control the engagement device so that the engagement device slips, when the electronic control unit determines that the power transmission system is in the resonance region; and control the motive power source when the electronic control unit determines that the power transmission system is in the resonance region, so that a rotational speed of the motive power source increases as compared with a case where the power transmission system is not in the resonance region.
