Abstract: A hydraulic brake system has: a force-pressure conversion element, which is in hydraulic connection with at least one wheel brake cylinder of at least one wheel; a volume-adaptation element in hydraulic connection with the at least one wheel brake and the force-pressure conversion element; and as an actuating unit for actuating the force-pressure conversion element, which actuating unit has an input element. The pressure in the at least one wheel brake cylinder is adjusted by operating the volume-adaptation unit and/or the actuating unit. For this purpose an actuating state of the input element is maintained by operating the actuating unit when the volume-adaptation unit is being operated.

Abstract: A vehicle-supported data processing system includes a plurality of processing units communicating with one another via a bus system, which are each supplied with operating power by at least one of the at least two different vehicle electrical systems. Multiple transmitter units for control information and multiple receiver units for the control information are among the processing units. The bus system is a ring bus, in which each processing unit is connected to at least two adjacent processing units by a bus segment in each case. The ring bus is divided, by potential separating devices, which are incorporated in the bus segments which connect processing units powered by different vehicle electrical systems, into a number of sections, which is smaller than the number of the processing units.

Abstract: Errors which may be detected by an error detection unit may occur during execution of a computer program which runs on a computer system and includes at least one run-time object. In order to handle a detected error particularly flexibly and to keep the computer system available as much as possible, an error handling routine is selected from a pre-selectable set of error handling routines as a function of an identifier assigned to the run-time object and the selected error handling routine is executed.

Abstract: A method for running a computer program on computing hardware, in particular on a microprocessor. The computer program includes multiple program objects designed as tasks, for example. Transient and permanent errors are detected during the running of the computer program on the computing hardware. To be able to handle these transient errors constructively when they occur in a computer system in such a way that the functionality and function reliability of the computer system are restored within the shortest possible error tolerance time, at least one program object that has already been sent for execution is set into a defined state on detection of an error and is restarted from this state. The program object is a runtime object of the computer program, for example, also known as a task. One or more tasks that are still being executed or have already been executed on occurrence of an error are restarted and run again.
