    摘要： The present invention provides an improved clock synchronization algorithm for a distributed system intended for real time applications by performing at the same time an off-set correction and a clock read correction at each node of the distributed system. Expensive oscillators can be avoided and synchronization can be established faster and with higher precision.

    摘要： A vehicle steering and braking system includes a distributed control loop in which a state-determining device for generating signals that describe current vehicle operation, an arithmetic unit for generating set point signals and a regulator unit for generating actuator signals are connected to one another by a data bus. The signals of the devices and units, which are transmitted via the data bus, are combined in cycles, one complete set of information being capable of being transmitted via the data bus in each cycle. Within a single cycle the signals of the respective units and devices are generated and transmitted via the data bus in the sequence: arithmetic unit—state-determining device—regulator unit. Each of the components comprising the arithmetic unit—state-determining device and regulator unit, however, can form the starting point of the sequence without changing the sequence itself.

    摘要： A central node for a data bus system includes a bus monitor unit with receiver means for registering signals on the data bus, and evaluation means which detect incorrect communication on the data bus and at least temporarily block communication by the user that causes the incorrect communication or compensate the incorrect communication of a user which is triggered by the interference influences. The bus monitor unit includes timing means which are triggered according to time patterns for the transmission of each user of the data bus, in order to detect an incorrect communication of a user if the latter transmits outside the time provided for it. The bus monitor unit is integrated into the central bus node and a plurality of bus branches of different users are combined at the central node so that the bus monitor unit can check a plurality of users for incorrect communication. In order to increase reliability, in addition to the bus monitor unit, a diagnostic unit is integrated into the central node. The latter monitors the bus monitor unit in terms of regular retriggering in response to the time patterns, so that the bus monitor unit can be deactivated in the absence of retriggering.
