Abstract: An automatic powershift transmission having a variable-speed transmission (2) with a transmission input shaft (4), a transmission output shaft (5). a plurality of gearsets (RS1, RS2, RS3) and a number of shifting elements (A, B, D, E, F). A starting element (3) is connected upstream of the transmission input shaft (4). The starting element (3) is in the form of a planetary gearset (6) having a ring gear (9), a planetary carrier (10) and a sun gear (12). The ring gear (9) and the planetary carrier (10) can be coupled to one another while the sun gear (12) can be locked with respect to the housing.

Abstract: A keyless entry system for a vehicle, in particular a motor vehicle, the keyless entry system including a device for unlocking at least one locked door of the vehicle in response to an electronic door opener being manipulated, and the device having at least one input element accessible from the outside of the vehicle. It is provided, that the door of the vehicle may be opened by inputting a code at one or a maximum of two input elements, the code being made up of a sequence of digital or quasi-digital signals, which are generated by alternately manipulating or not manipulating the input element(s).

Abstract: The electrical transmission system for a motor vehicle having a traction input, a power electronic system that controls the traction input and a cooling system for cooling the power electronic system. The cooling system is a refrigerator, or possibly a heat pump, with an integrated carburetor and a compressor unit. The electrical transmission system is particularly suitable for urban buses.

Abstract: The invention is directed to a method for adjusting the hydraulic pressure actuating at least one clutch of an automatic transmission. The hydraulic pressure is pregiven only by one pressure controller and the automatic transmission coacts with the motor which is especially a drive motor of a motor vehicle. The pressure supplied by the pressure controller is determined in dependence upon the trace of a pregiven motor desired torque.
