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.

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.

A brake system for a vehicle has a first and a second brake control device, four wheel actuator devices, and a first and a second signal line, the first signal line connecting the first brake control device to two of the four wheel actuator devices and the second signal line connecting the second brake control device to the two other wheel actuator devices, each of the four wheel actuator devices in the active state being additionally designed to detect whether a specified number of brake control devices and/or wheel actuator devices are in the inactive state, in which case a specified braking torque is exerted on the wheel of the vehicle associated with the brake control device.

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.

A brake system for a vehicle having a sensor device for providing a first and second sensor signal, a first and a second brake control device, which are directly connected to the sensor device and to provide a corresponding control signal for the first and/or second sensor signal, and a first and a second signal line for transmitting the control signal, the first signal line directly connecting the first brake control device to a first and second wheel actuator device and the second signal line directly connecting the second brake control device to a third and fourth wheel actuator device, the four wheel actuator devices exerting a braking torque corresponding to the control signal on the associated wheel, and the first wheel actuator device being directly connected to the second brake control device and/or the sensor device. A method for operating a brake system for a vehicle is also provided.

A method and a device for transmitting information in a network having at least three subscribers, as well as a corresponding network, the information being transmitted in at least a first frame of a predefined length and structure, and the first frame on a first transmission path being transmitted in a loop to the next, second subscriber in each instance, given a predefined transmission direction, the information being additionally transmitted in a second frame having the same length and structure as the first frame, the second frame on a second transmission path being transmitted to a one-after-the-next, third subscriber, the second transmission path and, thus, the second frame skipping the second subscriber, and an assessment being made in dependence upon at least one criterion, thus information, length or structure.

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.

Method, operating system and computing hardware for running a computer program

A method for running a computer program on computing hardware, in particular on a microprocessor, is described, the computer program including multiple program objects and errors being detected in the method while running the computer program on the computing hardware, the program objects being subdivided into at least two classes and program objects of the first class being repeated when an error is detected and, when an error is detected in one program object of the first class, which has already been sent for execution, this program object of the first class being restarted instead of a program object of the second class.

A method for executing a computer program on computing hardware, e.g., on a microprocessor, is provided, the computer program including multiple program objects and errors being detected in the method while running the computer program on the computing hardware. The program objects are subdivided into at least two classes, and multiple program objects are executed during one run, program objects of the first class being repeated when an error is detected and, when an error is detected in one program object of the first class, which has already been sent for execution, this program object of the first class is restarted instead of a program object of the second class after the other program objects of the first class of a run.

A method for executing a computer program on computing hardware, e.g., on a microprocessor, is provided, the computer program including multiple program objects and errors being detected in this method while the computer program is running on the computing hardware. When an error is detected, at least one program object, which has already been sent for execution, is transferred into a defined state and is restarted from there, and subsequent additional program objects are shifted.

A method for transmitting data, in which a first signature is formed according to a specifiable signature formation method as a function of the data to be transmitted, the first signature is transmitted together with the data a second signature is formed according to the signature formation method as a function of the transmitted data and the first signature is compared with the second signature. To reduce the likelihood of fault masking in monitoring the transmission of the data using signature analysis, a provision is made to invert the data to be transmitted, to form the first signature according to the specifiable signature formation method as a function of the data to be transmitted and of the inverted Data, to transmit the first signature and the data to invert the transmitted data, to form the second signature according to the signature formation method as a function of these inverted data and the transmitted data, and to compare the first signature with the second signature.

A steer-by-wire steering system has a steering wheel actuator and a braking device that acts on the steering column. The braking device is activated when the vehicle steering wheel is to be blocked or at least sharply braked, such as when the steering stop is reached or a wheel goes over the edge of a curb. The braking device functions like a switchable freewheel.
