摘要： A drive device includes: an actuator rotating, around a rotation axis, a shift drum having a lead groove formed on an outer peripheral surface; and an angle correction unit correcting a detection value of a rotation angle sensor that detects a rotation angle of the shift drum. The angle correction unit calculates the rotation angle of the shift drum at a reference position as a learning angle based on a correspondence between a displacement amount of a first engaging portion and a change amount of the rotation angle of the shift drum per a predetermined time of rotation of the shift drum at a predetermined speed. Then, the angle correction unit corrects the detection value of the rotation angle sensor based on an amount of deviation between the learning angle and a design angle.

摘要： A control device includes: an engagement mechanism having a first engagement element and a second engagement element; and an actuator that generates a thrust that brings the first engagement element and the second engagement element close to each other when the engagement mechanism is engaged. The control device performs engagement with the thrust of the actuator when a differential rotation speed of the engagement mechanism is less than a predetermined value. In the control device, a parameter indicating an operating state of the actuator is detected, a target differential rotation speed is calculated in accordance with a value of the detected parameter, and the differential rotation speed is controlled to the calculated target differential rotation speed.

摘要： A clutch includes a driving-side rotating body, a driven-side rotating body, a holding case, and a power transmitting member held by one of the driving-side rotating body and the holding case. The power transmitting member is moved between a non-engaging position and an engaging position where the driving-side rotating body engages with the driven-side rotating body. The clutch further includes a guiding member held by the other of the driving-side rotating body and the holding case. The guiding member has a cam portion engaged with the power transmitting member and guides movement of the power transmitting member between the engaging position and the non-engaging position. Relative rotation between the driving-side rotating body and the holding case occurs, resulting in that the power transmitting member is guided by the cam portion to move from the non-engaging position to the engaging position.

摘要： In a method and control device for adjusting a rotational speed of a shaft of a gear change transmission of a motor vehicle, a torque required for the acceleration of the transmission and derived from a drive motor is transmitted by means of an automated clutch and using the torque the rotational speed of the shaft is precisely and rapidly adjusted to a range around a target rotational speed by defining a desired value for a position of the clutch on a rotational speed difference between a measured rotational speed of the shaft and a target rotational speed so that the gear can then rapidly be changed.

摘要： An easily packaged torque monitoring system accurately captures driveline torque data for use by engine, transmission or other vehicle controllers. The torque monitoring system utilizes a structural member to hydraulically connect a driving member with a driven member. A pressure-sensing device is operatively connected with a fluid chamber in the structural member through which the driving member drives the driven member. The pressure-sensing device senses a pressure level within the chamber. The amount of torque transmitted from the driving member to the driven member is directly linearly related to the sensed pressure. In one embodiment, the pressure-sensing device is a surface acoustic wave sensor in contact with the hydraulic fluid that wirelessly relays a sensor signal (i.e., a signal with a value corresponding with sensed pressure and thus with torque) to a controller.
