Abstract: In a method for operating a hybrid drive system having multiple drive units each having a drive motor and a motor control unit, the motor control units are activatable in order to request partial drive torques from the drive units according to a drive strategy. At least one of the motor control units is configured to execute an adaptation function when an adaptation function condition is present. The drive strategy is selected as a function of a frequency of an execution of the adaptation function in the motor control unit.

Abstract: In a method and a device for operating a drive unit, a first output variable of the drive unit is restricted; a setpoint value of a second output variable of the drive unit is specified; and an actual value of the second output variable of the drive unit is determined. The setpoint value is compared with the actual value, and if it is determined that the actual value does not exceed the setpoint value, then the first output variable is restricted to a first value. If it is determined that the actual value exceeds the setpoint value, then the first output variable is restricted to a second value smaller than the first value.

Abstract: A method and a sensor system for transmitting sensor data are described. It is provided in the method that a sensor outputs an analog signal, a digital signal is generated as a function of the analog signal, the digital signal is encrypted and both the analog signal and the encrypted digital signal are transmitted to a receiver unit.

Abstract: The invention relates to a control unit comprising a data transmission device, comprising at least one module (6) which is arranged on a mounting plate (1) and actively connected to a power supply system. The data are as least forwarded to a second module (7) which is arranged on a second mounting plate (2). Data transmission from the first module (6) to the at least one additional module (7) proceeds via an optical transmission device (4).

Abstract: A method for ascertaining information about a device that has been exposed to a temperature, permitting a simple and reliable means of ascertaining information about the aging of the device. The temperature of the device is determined. Depending on the temperature or the temperature change achieved by the device, at least one counter is incremented. Information about the aging of the device is ascertained as a function of the counter reading achieved.

Abstract: To convey corrosive liquids, rubber hoses are customarily provided with an inner lining that is made of a synthetic material which is resistant to solvent. In order to achieve the previously unobtainable smooth, fold-free application of the thin plastic foil against the inner rubber layer of a hose, the present invention utilizes an extremely thin-walled contractible foil sleeve that is smoothly contracted upon a rigid fabrication mandrel. This foil sleeve then forms the base for the further build-up of the hose.

Abstract: A flexible, very high pressure hose as a flexible conducting member in hydraulic systems. The wall of the hose contains filamentary load-carrying cords which are embedded in two or more layers. The load-carrying cords are combined to form a plurality of strips which cross one another or are braided with one another. The present invention deviates from the heretofore known symmetrical arrangement where the strips of a given layer have the same number of load-carrying cords in both directions, and instead provides an asymmetrical layer construction including strips which in one direction have a different number of load-carrying cords than do the strips which extend in the opposite direction. While the local resistance to pressure remains the same, the advantages of the present invention are distinct improvements, primarily in the flexibility and the service life of the novel hoses.
