    • A data bus interface for a control unit, in particular for a motor vehicle control unit is described, as well as a control unit, in particular a motor vehicle control unit, having a data bus interface for accessing a data bus for communicating with another control unit via the data bus. A data bus interface may be used with a particularly high degree of flexibility and be manufactured economically. The data bus interface includes two arithmetic units, in particular two microprocessors, which communicate with each other via an internal data bus; and two transceivers which are connected either to the same external data bus or to two different external data buses and are interconnected with the two arithmetic units in such a way that the two arithmetic units are connected either to the same external data bus or to the two different data buses.
    • 描述了用于控制单元的数据总线接口,特别是用于机动车辆控制单元的控制单元,以及具有数据总线接口的控制单元,特别是机动车辆控制单元,该数据总线接口用于访问用于与另一控制器通信的数据总线 通过数据总线单元。 可以使用数据总线接口,具有特别高的灵活性并且经济地制造。 数据总线接口包括经由内部数据总线相互通信的两个运算单元,特别是两个微处理器; 以及两个收发器,其连接到相同的外部数据总线或两个不同的外部数据总线,并且与两个运算单元互连,使得两个运算单元连接到相同的外部数据总线或两个运算单元 不同的数据总线。
