    Abstract: A power transmission device for a vehicle equipped with a wet multiple disk clutch for disconnecting the power at the time of gearshift by using a clutch controller, wherein the amount of engagement where the clutch is half-engaged is learned maintaining precision. In the present invention, the clutch controller of the wet multiple disk clutch moves a clutch piston over the whole stroke thereof by using the working fluid for varying the amount of engagement at the start of learning the amount of engagement at a point where the clutch starts half-engaging and, immediately thereafter, the amount the clutch is half-engaged is detected. Upon moving the clutch piston, the working fluid present among the friction disks of the wet multiple disk clutch is drained and is replaced by the new working fluid avoiding detection error caused by the fluctuation in the temperature of the working fluid and eliminating unstable operation of the clutch piston caused by static friction of a large resistance. The amount of engagement at the point where the clutch starts half-engaging is determined by gradually increasing the amount of engagement after the clutch is disengaged and detecting a change in the rotational speed of the clutch input shaft.

    Abstract: A control system for a transmission includes an actuator module, a timer module, and a pulse module. The actuator module engages N hydraulic clutches and disengages M hydraulic clutches to operate the transmission in a gear ratio, wherein N and M are integers greater than zero. The timer module determines a first period starting when the transmission begins operating in the gear ratio. The pulse module selectively supplies a pressure pulse to P of the M hydraulic clutches based on the first period, wherein P is an integer greater than zero. A method for controlling a transmission is also provided.

    Abstract: An electromagnetic (EM) clutch assembly includes input and output discs, a plunger, a control solenoid, and a controller. The input disc is connected to a rotatable input member, and defines an input face having a mechanical feature. The output disc is connected to a rotatable output member, and includes a bore wall defining a bore. The plunger is positioned at least partially within the bore. The controller transmits a time-varying electrical control signal to the solenoid to thereby resonate the plunger toward the input disc, and transmits a steady-state electrical control signal to capture the plunger in an engaged position. Rotation of the discs is controlled until the plunger encounters the mechanical feature, thereby placing the assembly in an engaged state. A vehicle having a transmission and the EM clutch assembly is also disclosed, as is a method for controlling the clutch assembly via the electrical control signals.

    Abstract: A hydraulic drive system for storing and releasing hydraulic fluid includes a high pressure storage device, a low pressure storage device, and a pump-motor operating at a range of pump-motor speeds for converting between hydraulic energy and mechanical energy. The pump-motor is disposed between the high pressure device and the low pressure device. In normal operation, the hydraulic drive system enters a motoring mode where hydraulic energy is released from the high pressure storage device and converted to mechanical energy using the pump-motor. It also enters a pumping mode where mechanical energy is converted into hydraulic energy. A neutral state exists where hydraulic energy is neither stored nor released from the high pressure storage device. An approach for compensating for temperature changes using varying pressure limits helps to maintain the hydraulic drive system in normal operation, thereby promoting efficiency within the hydraulic drive system.
