    摘要: A dynamic damper device includes a variable inertial mass device that variably controls inertial mass of a damper mass, an elastic body that connects a rotary shaft rotated by power transmitted thereto and an input member of the variable inertial mass device, and a variable damping force device that variably controls a damping force to the elastic body. Accordingly, the dynamic damper devices have the advantageous effect that vibrations can be appropriately reduced.

    摘要: In order to properly perform vibration damping control in a vehicle 1 in which vibration occurs due to driving characteristics, a vibration damping control device 10 performs sprung vibration damping control of suppressing sprung vibration generated in the vehicle 1, by control of the torque that is generated in wheels 5 of the vehicle 1, with this vibration damping control device 10 performing vibration damping control suppression control of stopping sprung vibration damping control, or reducing a control amount of sprung vibration damping control, on the basis of engine speed and engine torque of an engine 14 that is a power source of the vehicle 1 during travel. As a result, it becomes possible to prevent vibration damping control from being brought to an inappropriate state, due to a travel state of substantial vibration, during vibration damping control.

    摘要: A method of managing tip-in bump in an automatic transmission includes detecting a set of conditions indicative of an impending throttle tip-in event, including calculating a speed difference between engine speed and turbine speed, and reducing a pressure command to a designated clutch of the transmission to a threshold level. The method also include setting an upper limit on engine torque, flaring the turbine speed during the tip-in event, and using proportional-integral-derivative control logic of a controller to reduce flare to about zero in a calibrated duration, thereby allowing the clutch to dissipate engine inertia and minimize the severity of the tip-in bump. A transmission in a vehicle is operatively connected to an engine and has a torque converter with a turbine. The transmission includes a clutch and a controller configured to manage tip-in bump performance in the transmission via the above method.

    摘要: A method of controlling a vehicle includes detecting vibration in a drivetrain of the vehicle with a fore/aft accelerometer during a launch event. An operating regime of the vehicle is identified concurrently with the detected vibration when the detected vibration is outside a predefined allowable range. A control strategy of the drivetrain is adjusted to define a revised control strategy to avoid the identified operating regime. The revised control strategy is applied to control the drivetrain to mitigate vibration in the drivetrain.

    摘要: A torque applied to a one-way clutch when a first motor generator and second motor generator are operated in a motor generator drive mode is restrained or prevented from becoming excessively high by setting a first motor generator sharing ratio in response to a driving torque target for the vehicle, by controlling operation of the first motor generator in response to a first motor generator first sharing ratio when vehicle vibrations due to cogging torque are likely to take place, and by reducing the torque from the first motor generator when the driving torque target is large. Torque applied to the one-way clutch which otherwise would become excessively high immediately after engine shutdown, is restrained or prevented by reducing the torque from the first motor generator in response to a second motor generator second sharing ratio when engine downtime is short.
