Abstract: To extend a power cylinder bore in a hydraulic block of a power brake system, a cylinder cover, which is in the form of a cylinder tube and is closed at one end, is fastened by means of a circumferential caulking in a fastening groove of the hydraulic block which encloses the power cylinder bore. An interference fit of a fastening flange of the cylinder cover in the fastening groove reliably seals the cylinder cover against the hydraulic block in a pressure-proof manner.

Abstract: The disclosure relates to a method for controlling a hydraulic pressure in at least one wheel brake of a hydraulic motor vehicle braking system, wherein a system pressure is generated by an electrical pressure supply device and, by control of an in particular normally open inlet valve, having an opening current characteristic curve, a required hydraulic pressure, which is lower than the system pressure, is set in the at least one wheel brake. In order to improve the pressure control, provision is made that the inlet valve is opened by application of an opening current, in particular below the opening current characteristic curve, and is switched over from the opening current to an intermediate current on the opening current characteristic curve.

Abstract: A method for operating an internal combustion engine: detecting a first signal from a knock sensor in a temporal measurement window for a first load point and for a first energization duration—assigned to a pre-injection—of an injector for an operating cycle; calculating a first first evaluation point from the first signal by a first metric; detecting a second signal from the knock sensor in the temporal measurement window for the first load point and for a second energization duration—assigned to the pre-injection—of the injector for the operating cycle; calculating by the first metric a second first evaluation point from the second signal; determining an optimum energization duration as an optimum of the first first evaluation point and the second first evaluation point; and storing and/or applying the optimum energization duration to the first load point and the first combustion chamber.

Abstract: A non-return valve for a vehicle hydraulic-power brake system. The non-return valve has a valve-seat part in the form of an apertured disk, onto which is pressed a valve cage in which a valve ball is disposed as shut-off member and a helical compression spring is disposed as valve spring. A bowl-shaped filter is secured in a depression in the valve-seat part opposite the valve cage.

Abstract: Embodiments of the invention relate to the processing of a safety-related user program for a safety control system. The generation of the machine code for the safety-related control takes place on a cloud computer. The data required for generating the machine code such as the source code data of the user program, are secured with a unique signature and transmitted to the cloud computer. The machine code is generated on the cloud computer from the transmitted data. A new signature is generated via the resultant data and the signature from the preceding step. The entire safety life cycle is also covered, since each step in the life cycle is automatically documented and may be clearly tracked at any time, and corruptions of a step may be detected.
