Abstract: A method of operating an internal combustion engine in a motor vehicle has the steps of determining angular positions of a crankshaft and a camshaft from signals of two detecting devices, monitoring a relative angular position of one of the shafts relative to the other of the shafts, and, depending on whether a change of the determined actual relative position is located outside the tolerance region, releasing an action, and also a computer program, a storage medium, a control and/or regulating unit, and an internal combustion engine with the use of inventive method are proposed.

Abstract: A system for controlling and/or regulating operational sequences in a motor vehicle having several equal-access control units for controlling and/or regulating certain functions in the motor vehicle. Control units each have a volatile memory, and a nonvolatile memory in which a loading routine is included. They are connected to one another via a time-controlled communications system.

Abstract: A method of mutual monitoring of components of a distributed computer system for a safety-relevant application in a motor vehicle in particular. The components are interconnected by at least one communication system. To make the mutual monitoring of components as simple and comprehensible as possible and to save on additional hardware components for monitoring, in a plurality of components of the computer system an internal monitoring function which detects faults in the monitored component and a mutual monitoring function which performs a mutual check on results determined by the components and makes a majority selection from the results are implemented, and both the result of the internal monitoring function and the results of the mutual monitoring functions are taken into account in a decision as to whether there is a fault in a component.

Abstract: A method of triggering a component in a distributed safety-related system, e.g., a component of an X-by-wire system in a motor vehicle, is described. The component is triggered by a first triggering module assigned to the component and including at least one first microcomputer system. To monitor the microcomputer system, a monitoring unit which is independent of the first microcomputer system is provided. In addition to the first microcomputer system, the distributed safety-related system includes at least one additional microcomputer system which is connected to the first microcomputer system for the purpose of data transfer, e.g., via a physical databus. The additional microcomputer systems assume the functions of the monitoring unit. Thus, it is possible to do without a separate monitoring unit.

Abstract: An electrically controlled, decentralized control system in a vehicle includes at least two energy sources which are independent of one another and at least two control units. In addition, at least one high-current load is allocated to each control unit. The high-current load is permanently allocated to one of the energy sources, while the control units are selectively switchable to the one or the other energy source.

Abstract: A dispersed control system for use in a vehicle. The dispersed control system includes a plurality of electrical control units that exchange data via a communication system. The system includes at least two power sources that are independent of each other and that supply each of the plurality of electrical control units with a voltage. The communication system includes at least two channels, and bus drivers are provided in each electrical control unit so that each channel is supplied with a voltage from a different one of the at least two power sources.

Abstract: A method of and a device for operating a decentralized control system, at least two control units are provided to control at least one actuating element each. In this control, different operating modes are to be differentiated, the selection of the respective operating mode of the individual control unit is made by the at least two control units on the basis of at least one status signal.

Abstract: An electrical brake system for a motor vehicle including control modules for controlling the front axle brakes and the rear axle brakes, in which the control modules for the front axle brakes include fault-tolerant behavior, and in which the control modules for the rear axle brakes do not have any external effect in the event of a fault state in the area of the control module.

Abstract: The system includes a central memory, in which all programs necessary for controlling/regulating the operational sequences of a vehicle are stored. At the start of the system, the control units load the needed programs into their working memory via indirect memory access. The method provides that, after the system is switched on, the units first identify themselves. After that, by means of the loading programs, the programs are loaded from the central memory into the working memory of each control unit via indirect memory access.

Abstract: A method and a device for controlling wheel brakes is proposed. To improve the availability and to fulfill legal requirements imposed on an electrical braking system, a control of the valves derived from a second power circuit independent of the first one is provided in the event of a fault, via which the braking pressure in the at least one wheel brake can be set even in the event of a fault.

Abstract: An electrically controlled, decentralized control system in a vehicle having control modules, each of which is assigned a vehicle control element for actuation. The actuation is carried out as a function of a driver's input which is formed in each control module on the basis of sensor signals that represent the actuation of an actuating element by the driver. In this context, at least three sensors are provided for detecting the actuating signals, one actuating signal being supplied directly to each control module.
