Abstract: Hydraulic control device for an automated dual clutch transmission having first and second clutches with first and second sub-transmissions and also a gear shifting system. The hydraulic control device has a regulating unit that predetermines at least one regulated pressure and/or one regulated volume flow for actuating the first and second clutches and shifting system. The hydraulic control device has a switching device that is arranged between the regulating unit and the clutches or the shifting system, switching the regulated pressure or volume flow to the clutches or the shifting system. The regulating unit includes a first regulating valve and a second regulating valve that is connected to an oil pressure supply having a system pressure regulator and an electric oil pump.

Abstract: The invention concerns a method for automatically controlling a motor vehicle (10) for switching from a “normal” mode to a “freewheel” mode, the vehicle (10) comprising an engine (12) capable of providing engine torque to drive wheels (14) via an automatically controlled clutch device (18) that comprises a drive shaft (15) and a driven shaft (16). A transition step (E1) is interposed chronologically between the “normal” mode and the “freewheel mode” during which the engine (12) is automatically controlled in such a way that the driven shaft (16) and the drive shaft (15) turn at the same speed without transmitting torque to the drive wheels (14).

Abstract: A transmission for a motor vehicle, includes a housing (1), which has a first housing part (10) and a second housing part (20), wherein, in the assembled state of the transmission, the first housing part (10) and the second housing part (20) are joined together, having a vent duct (30), through which air can escape from the transmission, and having a separate breather element (31), which extends into the first housing part (10) and forms at least one first duct wall of the vent duct (30), and the breather element (31) is located in a plug-in position in the first housing half (10) and has a fixing stop (37), against which the second housing part (20) bears in the assembled state of the transmission and thus securely fixes the breather element (31) in the plug-in position.

Abstract: A manual transmission includes a coaxially arranged input shaft and output shaft, a first intermediate shaft and parallel second intermediate shaft, spaced from the input shaft, a drive side gear pair with a drive gear rotationally fixed on the input shaft and an intermediate gear rotationally fixed on the first intermediate shaft, and an output side gear pair with a second intermediate gear rotationally fixed on the second intermediate shaft and an output gear rotationally fixed on the output shaft, wherein, drive torque is transferred from the input shaft to the output shaft over the drive side gear pair, while no drive torque is transferred over the output side gear pair and, with at least three other switchable gears, drive torque is transmitted from the input shaft to the output shaft over the output side gear pair, while no drive torque is transmitted over the drive side gear pair.

Abstract: A method for reaching a neutral position N located between two end positions of a gearshift fork in a shift transmission in a motor vehicle from a starting position of the gearshift fork. The method allows finding the neutral position of the gearshift fork without a sensor determining the position of the gearshift fork or in the alternative in case such the sensor is defect.
Abstract translation: 一种从变速叉的起始位置到达位于机动车辆的变速传动装置中的变速叉的两个端部位置之间的中立位置N的方法。 该方法允许在没有传感器确定换档叉的位置的情况下或在传感器缺陷的情况下，找到换档叉的空档位置。
