  • Publication number: 20190195344
    Abstract: A method for actuating a hydraulic system of a transmission comprising a variable displacement hydraulic pump and a pilot-controllable system pressure valve, the method including, in order to determine a pump characteristic curve of the hydraulic pump, initially transferring the hydraulic system into a defined operating condition range in which the volumetric output flow, routed via the system pressure valve and applied at the system pressure valve by the hydraulic pump, is greater or less than a hydraulic fluid flow out of the hydraulic system. The method further includes pilot-controlling the system pressure valve to set a defined pressure level of the system pressure. The method additionally includes reducing or increasing the volumetric output flow while monitoring the system pressure, and determining a volumetric output flow corresponding to the hydraulic fluid flow of the hydraulic system with a certain deviation of a current system pressure from the defined system pressure.

  • Publication number: 20190186303
    Abstract: An oil supply device for a vacuum pump of an internal combustion engine, in particular of a car, including an oil feed line via which the vacuum pump can be supplied with oil for lubricating the vacuum pump. The oil feed line includes a valve connected to the oil feed line in an oil-conducting manner, which valve has a piston that is accommodated in a valve interior of the valve and can move at least between a supply position in which it allows a supply of oil to the vacuum pump and a blocking position in which it prevents the supply of oil to the vacuum pump, and has a spring element, by means of which a spring force that holds the piston in the blocking position can be applied to the piston when the internal combustion engine is at rest.

  • Publication number: 20190163452
    Abstract: A method for generating program code based on one or more blocks of a block diagram in a technical computing environment, an identifier being assigned to at least one, preferably each, of the one or more blocks of the block diagram. A processor opens the block diagram in the model editor, converts the block diagram to an intermediate representation using the code generator, wherein the conversion comprises checking if a replacement condition is fulfilled for a current block in the block diagram. Checking the replacement condition includes verifying that a predefined functional code unit is assigned to the identifier of the current block, in that case changing the block to a placeholder containing input/output-definitions but no functionality. The processor then converts the intermediate representation to program code, the conversion comprising adding a predefined functional code unit from the data definition tool to the definition code corresponding to the placeholder block.
