The invention relates to a method for transmitting data via a communications channel (106), wherein the data is transmitted with a transmission frame, the transmission frame has at least one prioritisation field (PCP) for establishing the priority of the message and a data field, the prioritisation field (PCP) functions to control the bus access by prioritizing the messages. For this purpose, a bus access controller is used, in which the priority of at least the last received data packet is stored in a minimum priority storage cell (330). After receiving a data packet, a timer (320) is started, for which a timeout value is set, which is reset when a following packet is received. After reaching the timeout value, a decrementing of the value stored in the minimum priority storage cell (330)occurs. Thereafter, for the purpose of bus access control, when sending a packet, it is checked whether the priority of the packet to be sent is lower than the value stored in the minimum priority storage cell (330), and the sending of the data packet is prevented if the priority of the packet is lower than the value stored in the minimum priority storage cell (330).

The invention relates to a method for transmitting data via a serial communication bus, a bus interface and a computer program. An extension of the existing CAN FD data transmission protocol is related. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the DataField, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

The invention relates to a hardware architecture for controlling a safety-relevant process. At least two microcontrollers 250, 350 are utilized for controlling the process in at least two control branches, wherein the respective microcontrollers 250, 350 are designed to control the safety-relevant process. This is therefore a redundant system. In a method, the microcontrollers 250, 350 process thedata from at least one sensor 276, 376, which detects the actual characteristic of the respective control branch. Between the two microcontrollers 250, 350, the data of the respective sensor 276, 376are exchanged, and in a decision module 258, 358 provided for each microcontroller 250, 350, a check is made to determine whether the data from the sensors 276, 376 are consistent. In response to aninconsistency being detected, a majority decision is made and a model value used in forming the majority decision, is calculated in the microcontroller 250, 350 based on control commands so the control of the safety-relevant process by the microcontroller 250, 350 of the control branch, whose data were detected as erroneous in the majority decision, is disabled. Third sensors that would otherwisehave to be used for check can be saved by calculating model parameters.
