摘要： A controller including an electronic control unit, the electronic control unit is configured to determine at least one of whether a first absolute value is at least equal to a first threshold and whether a second absolute value is at least equal to a second threshold. When the electronic control unit determines that at least one of the first absolute value and the second absolute value is at least equal to the corresponding threshold, torque capacity of an automatic clutch is controlled such that the automatic clutch is brought into a slipping state. The first absolute value is an absolute value of rotational acceleration of an input shaft of a transmission, and the second absolute value is an absolute value of rotational acceleration of drive wheels.

摘要： A vehicle includes a prime mover, transmission, and controller. The transmission, e.g., a DCT or 8-speed automatic transmission, includes an input member, an output member, gear sets, and a plurality of clutches. The controller monitors the transmission for a threshold tie-up condition via a method, which includes processing clutch control input signals and a gearbox status signal to identify the clutches involved in a present operating mode of the transmission, e.g., a shift, neutral, or fixed gear. The controller determines the torque capacity of each involved clutch, compares the determined clutch torque capacities to respective calibrated clutch torque capacities, and executes a control action in response to a threshold tie-up condition. The threshold tie-up condition is present when the determined clutch torque capacities exceed the calibrated clutch torque capacity for at least one of the involved clutches for longer than a calibrated duration.

摘要： In a transmission control device for a hybrid vehicle, when an engine torque is equal to or less than a predetermined value during a constant speed traveling, a learning engine rotational speed is set to a rotational speed being higher by +α than the present engine rotational speed. Then, a learning engine torque is calculated that corresponds to the learning engine rotational speed, a learning clutch actuator operation amount is obtained that corresponds to the learning clutch torque, and a clutch actuator is operated based on the learning clutch actuator operation amount. Thereafter, when the engine rotational speed and the engine torque are in stable states, a clutch torque value corresponding to the learning clutch actuator operation amount is compensated by a stable engine torque value.

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.
