摘要： A control apparatus for a linear solenoid valve configured to regulate a hydraulic pressure in a vehicle transmission. The control apparatus includes a hydraulic control portion configured to output a control command signal that is applied to a solenoid of the linear solenoid valve. The hydraulic control portion outputs, as the control command signal, a regulating control command signal by which the hydraulic pressure is to be regulated to a regulated pressure value that is dependent on a vehicle driving state. When the regulated pressure value is in a certain pressure range in which vibration-based noise is likely to be generated by vibration of the linear solenoid valve that is operated with the regulating control command signal being applied to the solenoid, the hydraulic control portion outputs, as the control command signal, a noise-restraining command signal by which generation of the vibration-based noise is restrained.

摘要： A hybrid vehicle with an engine and a rotary machine each coupled to a drive wheel in a power transmittable manner, comprises: an electronic control device that makes the rotary machine output a starting-time compensation torque to compensate a drop in a drive torque caused in a starting process of the engine in addition to a running torque when the engine is started while the vehicle is in a running state in which the drive torque is generated by the rotary machine and the engine is in a stopped state. The electronic control device starts the engine such that a starting-time inertia torque that is generated according to starting of the engine and causes the drop in the drive torque is made smaller when a torque margin of the rotary machine which is applied to the starting-time compensation torque is relatively small than when the torque margin is relatively large.

摘要： A controller and a control method for a vehicle including an engine with a supercharger and an automatic transmission provided in a power transmission path between the engine and driving wheels are provided. The controller is configured to perform learning control of learning a command value associated with gear shifting of the automatic transmission. The controller is configured to limit a supercharging pressure of the supercharger when the automatic transmission is performing gear shifting to be equal to or less than a predetermined pressure until initial learning which is performed by the learning control unit in a predetermined period after the vehicle has been manufactured is completed.

摘要： 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.

摘要： 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.

摘要： A control apparatus for a hybrid vehicle that includes an engine serving as a drive force source, an electric motor serving as a drive force source, drive wheels, a storage battery for supplying and receiving an electric power to and from the electric motor, a transmission mechanism for transmitting a drive force supplied from each of the drive force sources toward the drive wheels. During running of the hybrid vehicle by a drive force of the electric motor with the engine being stopped, the control apparatus is configured to determine whether the engine is to be started. When determining that the engine is to be started during the running of the hybrid vehicle, the control apparatus is configured to cause a gear ratio of the transmission mechanism to be changed and to cause the engine to be started after the gear ratio of the transmission mechanism has been changed.

摘要： A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion. An output-side rotary shaft has oil passages for supplying lubricating oil to a tolerance ring. Lubricating oil is forcibly supplied through these oil passages to an annular space in which a tolerance ring is accommodated.

摘要： 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.
