摘要:
A method for controlling the shifting of a transmission uses a control device for shifting gears in two different operating modes. In a first operating mode, the transmission is operated in an automatic mode and the shifting is automatically carried out, essentially based on detected driving parameters and with the aid of the control device. A respective automatic driving program and/or a respective top selectable gear can be selected in the automatic mode. In a second operating mode, the transmission is operated according to an automated manual shifting mode by using an actuating device. The respective automatic driving program and/or the respective top selectable gear can be selected by using the actuating device when the transmission is in the automatic mode. A device for controlling the shifting of a transmission is also provided.

A method and a device for controlling a motor vehicle drive train determine the direction of rotation of the drive train by evaluating sensor signals of a first sensor unit on the output side of the drive train. The first sensor unit includes a sensor wheel fastened to a rotatable component on the output side of the drive train and two rotational speed sensors which are fixed with respect to a housing and are placed circumferentially next to one another. In order to speed up the determination of the direction of rotation, the sensor signal of a second sensor unit on the input side of the drive train is evaluated. The second sensor unit includes a sensor wheel that is fastened to a rotatable component on the input side of the drive train and a rotational speed sensor that is fixed with respect to the housing.

The invention relates to a dual clutch transmission (1) for a motor vehicle, comprising a first and a second transmission input shaft (EW1, EW2), at least one drive shaft, in particular a first and a second drive shaft (TW1, TW2), wherein a first friction clutch (K1) and certain gear stages, preferably a first, a third, a fifth, and/or a seventh gear stage, are associated with the first transmission input shaft (EW1) and a second friction clutch (K2) and certain other gear stages, preferably a second, a fourth, and/or a sixth gear stage, are associated with the second transmission input shaft (EW2). The gear stages are formed by several gear pairs, each of which connects the transmission input shaft (EW1, EW2) and the drive shaft (TW1, TW2), wherein each gear pair is formed by a fixed wheel (2 to 5, 12, 13) and a loose wheel (6 to 9, 14 to 17), wherein several synchronizing devices are associated with the loose wheels (6 to 9, 14 to 17), and wherein the synchronizing devices have several interacting frictional surfaces. A multiple synchronizing device is provided as the synchronizing device for each of the two higher gear stages and a single synchronizing device is provided as the synchronizing device for the lower gear stages.

The invention relates to a controller protective device for a dual-voltage electric system (1). Said protective device comprises two galvanically linked electric systems of different voltage in which electric consumers R1, R2 are located. According to the invention, a protective diode (3) is switched to the non-conducting direction in parallel to the electric consumers R1 in the electric system with the lower voltage.
