Subscriber station for a serial bus system and method for communication in a serial bus system

A bus system, comprising:

• a bus;
• and
• at least two subscriber stations which are connected to one another via the bus in such a way that they can communicate in series with one another and of which at least one subscriber station is a subscriber station including:
• a communication control device configured to control a communication of the subscriber station with at least one other subscriber station of the bus system and to evaluate at least one signal received from a bus of the bus system, wherein in the at least one signal, a bit time in a first communication phase can differ from a bit time in a second communication phase, and
• a re-integration module configured to re-integrate the communication control device into a communication on the bus to temporally synchronize the communication control device to a signal transmitted from the at least one other subscriber station of the bus system, which the signal is created based on a frame for communication in the bus system,
• wherein the re-integration module is configured to check at least one predetermined re-integration condition in order to decide whether the operating mode of the communication control device is or is not to be switched into an operating mode for transmitting frames to the bus and/or receiving frames from the bus, and
• wherein the re-integration module is configured to use in the check at least one predetermined re-integration condition having a sequence of bits in which a value of a last bit differs from that of preceding bits;
• wherein each of the at least two subscriber stations also has a transmitting/receiving device for transmitting a transmission signal to the bus of the bus system and/or for receiving a signal from the bus of the bus system.

A method for communication in a serial bus system, wherein the method is carried out with a subscriber station of the bus system includes a communication control device and a re-integration module, wherein the method comprises the following steps:

• controlling, with the communication control device, a communication of the subscriber station with at least one other subscriber station of the bus system and evaluating a signal received from a bus of the bus system, in which signal a bit time in a first communication phase can differ from a bit time in a second communication phase;
• and
• performing a re-integration with the re-integration module for re-integrating the communication control device into a communication on the bus in order to temporally synchronize the communication control device to a signal transmitted from the at least one other subscriber station of the bus system, the transmitted signal having been created based on a frame for communication in the bus system;
• wherein the re-integration module checks at least one predetermined re-integration condition in order to decide whether an operating mode of the communication control device is or is not to be switched into an operating mode for transmitting frames to the bus and/or receiving frame from the bus, and
• wherein the re-integration module uses in its check at least one predetermined re-integration condition having a sequence of bits in which a value of a last bit of the sequence differs from that of preceding bits of the sequence.
