Abstract: A control device controls a torque transmission device. The torque transmission device includes an actuator that operates by being energized and a torque transmission portion that is switched to a transmission state or a non-transmission state by the actuator operating, and transmits a torque between a first transmission portion and a second transmission portion when the torque transmission portion is in the transmission state. The control device includes a target calculation unit, a mode determination unit, and a control unit. The target calculation unit calculates a target transmission torque that is a torque to be transmitted between the first transmission portion and the second transmission portion. The mode determination unit determines an operating mode among an engagement mode, a release mode, and a steady mode. The control unit controls the actuator based on the operating mode determined by the mode determination unit.

Abstract: A filtering pulley has a hub configured to be fixed to a shaft for rotation thereabout, a crown mounted coaxial and rotationally free on the hub, and a plurality of elastic groups arranged circumferentially with respect to the hub and to the crown and interposed, each, between a pair of first elements integral with the hub and between a pair of second elements integral with the crown. The first elements have at least two spokes, carried by an actuator that is made of two portions that can be selectively coupled based on angular position data between the crown and the hub and/or based on data of torque transmitted between the different elements of the system comprising this pulley.

Abstract: An adaptive control device is provided for a vehicle starting clutch. The adaptive control device includes a reverse brake as the starting clutch, and a clutch adaptive controller. The reverse brake is interposed between an engine and motor/generator, and the left and right rear wheels and is slip-engaged at a time of starting. The clutch adaptive controller performs clutch adaptive control, in which the reverse brake is subjected to a state in which a temperature of the reverse brake is at, or above, a second threshold for a timed period, at least one time before a vehicle begins to move.

Abstract: 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.

Abstract: The hydraulic control device includes a hydraulic fluid temperature estimation means for estimating the temperature of the hydraulic fluid supplied to the hydraulic clutch (actuator). The hydraulic fluid temperature estimation means calculates an output of logistic regression from an integrated value of driving currents and an average value of driving voltage of the electric motor. If the calculated output of the logistic regression is equal to or more than a first threshold value, the hydraulic fluid estimation means calculates a posteriori probability from such output. If the calculated posteriori probability is equal to or more than the second threshold larger than the first threshold value, the hydraulic fluid temperature estimation means determines the posteriori probability to be a final determination result, thereby determining the temperature of the hydraulic fluid to be a predetermined temperature.

Abstract: A method is provided for controlling an external control type fan clutch. The method controls the On/Off of an electromagnet-activated valve for an oil feed adjusting hole. The method uses a PID control on the basis of radiator cooling liquid temperature, fan speed, transmission oil temperature, vehicle speed, engine speed, compressor pressure of an air conditioner, and an On/Off signal of the air conditioner. Individual gains of the PID control are determined by a gain matrix containing the optimum fan speed demanded by the engine, the actual metered fan speed, and the engine speed. The PID control is made on the basis of the gains to that a control signal is outputted. The control method can improve mileage, raise the cooling efficiency of an air conditioner and suppress fan noise.
