摘要： A hydraulic system for actuating a transmission shifting element that comprises control and shifting valves. A first surface of a valve slide of the control valve is a differential surface between two functional surfaces of the slide that axially bound an area of the slide having a smaller diameter, by which the actuation pressure is adjusted. When the shifting valve is in a second switch position, a total force component acts upon the slide of the control valve which moves the slide such that the actuation pressure is equal to a system pressure. The total force component corresponds at least to the sum of a first force component equivalent to a pressure signal applied to a second surface of the slide of the control valve and a second force component equivalent to an actuation pressure applied to the first surface of the slide of the control valve.

摘要： A transmission device has at least two change-under-load shift elements with transmission capacities that are varied an actuation device. A method for operating a drive train including transmission and drive engine includes a step that when the transmission is shifted, one of the shift elements, which is engaged in the force flow, is disengaged by the actuation device and the other shift element, which is engaged, is disengaged. The actuation device includes an actuator which applies an actuating force to actuate the shift elements and a coupling device by which the actuator communicates with the shift elements to actuate them, such that an actuating force of the actuator, which is actuating the shift element to be disengaged, can be reduced, while an actuating force of the actuator, which is actuating the shift element to be engaged can simultaneously be increased.

摘要： A engine control system for an automatic transmission includes an engine torque control module that increases engine torque from a first torque level to a second torque level during a period before a shift from a first gear ratio to a second gear ratio, wherein the first gear ratio is greater than the second gear ratio, wherein the first torque level is based on driver input and vehicle speed, and wherein the second torque level is based on the first torque level and the first and second gear ratios. A transmission control module decreases a torque capacity of a first clutch to a third torque level during the period and increases a torque capacity of a second clutch to a fourth torque level during the period, wherein the fourth torque level is based on the second torque level and a torque gain of the second clutch.

摘要： A dual clutch transmission comprises a first clutch to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches. A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is established by a mode setting means, the one of the first and second clutches is engaged to drive the backward-traveling drive train by setting a speed change manipulator at a backward-traveling position, and the other of the first and second clutches is engaged to drive a fixed one forward-traveling speed drive train by setting the speed change manipulator at a forward-traveling position. While the reverse mode is established, the backward-traveling drive train and the fixed one forward-traveling speed drive train are kept activated regardless of whether the first or second clutch is engaged.
