The disclosure relates to a participant station for a bus system and to a method for increasing the data rate of a bus system. The participant station comprises a device for receiving a message from at least one other participant station of the bus system via the bus system. In the bus system, an exclusive collision-free access of a participant station to a bus line of the bus system is ensured at least temporarily. The participant station also comprises a testing device for testing whether or not the received message is specified for the participant station and an error processing device for processing errors of the received message only when the test carried out by the testing device indicates that the received message is specified for the participant station.

Subscriber station for a bus system, and method for increasing the data rate of a bus system

A participating station for a bus system and a method for data transmission in a bus system are provided. The participating station comprises a transceiver unit for transmitting a message to and/or receiving a message from a further participating station of the bus system, and a switching unit for switching a connection to at least one further participating station of the bus system between an open and a closed state, wherein the switching unit is designed for the selective connection control of the participating station to at least one further participating station of the bus system on the basis of at least a part of the message received from the transceiver unit.

Participating station for a bus system and method for data transmission in a bus system

A method for monitoring a communication network, which includes a plurality of processing units which communicate with one another via a communication medium, a channel of the communication medium being measured using channel estimation; from a result of the channel estimation, a characteristic variable being produced; and, with the aid of the characteristic variable, a decision is made as to whether a manipulative change of the communication network has occurred.

Method for monitoring a communication network

A method and a device is provided to allow additional data to be transmitted between at least two users of a bus system. The transmitted data frames have a logic structure according to the CAN standard ISO 11898-1, and at least two additional short bits are inserted within a temporal bit length of at least some of the CAN bits such that at least for one of the two possible values of the current CAN bit, the first one of the additional bits inserted into this CAN bit is transmitted using a bus level that is the opposite of this value.

Method and device for a serial data transmission with additionally inserted data

In a method for enabling transmission of larger data quantities relatively rapidly in a data network, the sent data frames have a logical structure according to CAN Specification ISO 11898-1, the bit length in time within a data frame being able to assume at least two different values; for a first specifiable range within the data frame, the bit length in time being greater than, or equal to a specified minimum value of approximately one microsecond and in at least one second specifiable range within the data frame the bit length in time compared to the first range is at least halved, preferably less than halved; the change of the bit length in time being implemented by using at least two different scaling factors for setting the bus time unit relative to a shortest time unit or the oscillator clock pulse during running operation.

Method and device for serial data transmission at a switchable data rate

A device for connecting to a two-wire communications bus, a bus station that, while utilizing the device, is able to send messages, represented on the bus lines as dominant and recessive bus levels, to additional connected bus stations and receive same from them. The device includes (a) an arrangement setting a dominant bus level in the form of a first voltage difference between the two bus lines by driving a first electric current, and the device is suitable for the recessive bus level to set in as the second voltage difference between the two bus lines, at least partially by the flowing of a discharge current via terminating resistors connected to the bus lines; and (b) an arrangement to speed up the setting of at least one of the bus levels by driving at least one additional electric current, at least in response to the presence of a switching condition.
