Abstract: A motor vehicle with a hybrid drive system (1) comprising an internal combustion engine and an electric machine, one of an automatic or automated transmission (2) connected between the hybrid drive (1) and a drive output (3) and a driver-operated element (4). The driver-operated element (4) has several conditions that can be selected by a driver with which one of a number of driving ranges or one of several groups of gears are associated for operation of the transmission. The driver-operated element (4) has at least one condition that can be selected by the driver with which, alternatively or in addition to a driving range or group of gears, a hybrid function mode is associated.

Abstract: A method for shifting an automatic transmission (8) of a motor vehicle having a hydrodynamic, converter (6), when the vehicle slows from driving to a standstill a predetermined stopping condition of the automatic transmission (8) exists, such that the transmission (8) is shifted into neutral. To avoid disadvantages from shifting into neutral immediately after the motor vehicle is stationary, such as an increase in fuel consumption by a tractional torque operation of the converter, a disengagement impact upon shifting into the standby mode; an unexpected rolling of the vehicle, when stopping occurs on an incline following a shift into neutral. The automatic transmission (8), conforming to predetermined stopping conditions, shifts even during the driving state into neutral.

Abstract: The invention relates to a method for influencing an automated transmission taking into consideration the tractional resistance with which the magnitude of an external tractional resistance can be determined easily and without need of data exchange with devices outside the vehicle, the same as independently of a digitalized road map of the area in which the vehicle drives and with low construction complexity. In particular a topographical information of the area in which the vehicle drives is obtained which allows a tractional resistance detection unit, optionally in combination with additional influencing variables in relation to the external tractional resistance, to act upon the controller of an automated transmission so that by shifting the gear change points or selecting a suitable program, reduces both the fuel consumption and the pollutant and noise emissions.

Abstract: Method for control of a proportional magnet comprising a magnet core, a magnet armature, a magnet coil for operating a control element in a shift valve or a proportional pressure-control valve, particularly a pressure-control valve for clutch operation in an automatic motor vehicle transmission, and comprising an electronic control device, whereby the magnet core may be moved back and forth between a control region and a hold region with a magnetic hold position of the magnet armature and a defined transition from the control region to the hold position may be executed and whereby mechanisms are provided for recognition of the movements of the magnet armature.

Abstract: A method for determining characteristic parameter values within a transmission that includes, for example, hydraulically-operated shifting elements, hydro-dynamic brakes, and hydro-dynamic torque converters. Slip regulation is used to determine the actual slip at a transmission element, whose characteristic parameter values are to be determined, before engagement. This element to be adapted is activated by means of pressure application, and thus a specified slip is set that is clearly different from the actual slip at lower torques. The applied pressure or flow may be determined from the set slip, and occurrence of a set slip allows the occurring pressures to be determined.

Abstract: A proportional pressure control valve is described capable of serving as a pilot, servo or direct control valve and having a pressure reducing function and a pressure maintaining function. The valve is comprised essentially of a valve housing (2) with inlet and outlet ports (4, 5, 6), a control element (7), an armature rod (8) and a proportional magnet (3). The proportional magnet (3) is an assembly of a magnet core (10), a magnet armature (11) and a magnet coil (12), whereby the proportional magnet (3) when in its range of operation possesses a nearly constant magnetic strength. In accord with the invention, when in a holding position of the magnetic armature (11) the smallest possible gap (13) exists between the magnet armature (11) and the magnet core (10).

Abstract: A proportional pressure control valve serves as a direct control valve with a pressure reducing function and a pressure holding function. The valve, includes a valve housing (2) with inlet and outlet . ports (4, 5, 6), a control element (7) which has a feedback facility, an armature rod (15) and a proportional magnet (3). The proportional magnet is comprised of a magnet core (17), a magnet armature (16) and a magnet coil (18), wherein this proportional magnet (3) in its operational range possesses a nearly constant magnetic force. In accordance with the invention, in a holding position of the magnet armature (16), the smallest axial space (21) between the magnet armature (16) and the magnet core (17) is so dimensioned, first, that the magnetic force between these two components (16, 17) when in the holding position is greater than the magnetic force in the operational zone of the proportional magnets (3), and second, that the magnet armature (16) can be fixed in the holding position by this magnetic force.

Abstract: The oil supply with an orientation toward requirements in a transmission is implemented by a system of control and regulating modules. Mentioned in particular, here is a combined control and regulating module that is electronically driven and mechanically regulates the pressure. The controlled variable is a coil current that increases proportionally as the pressure increases. One disadvantage is that, in the case of a system failure, no coil current flows and the pressure is also minimal. In the present invention, by contrast, a maximum pressure is provided in the hydraulics even without current. This ensures that during a system failure that the operation of control elements that can only be shifted using high pressure will continue. This is implemented via a combined control and regulating module. The control unit is a magnet system that moves the regulating module and a sliding valve (14).
