Electronic vehicle controller with a databus capability

An electronic vehicle controller comprising:

• a processor unit;
• a communication output stage for coupling the controller to a databus;
• and
• a data protocol device connected between the processor unit and the communication output stage;
• wherein
• said data protocol device variably sets a data protocol to be used for a respective data transfer, as a function of protocol control information which is supplied as an input to said data protocol device;
• and
• the data protocol device comprises
• a transmission block having a predeterminable number of data input channels on a processor unit side thereof, a predeterminable number of data output channels on a bus side thereof, and means for transposing data from the input channels to the output channels, which means include a transmission multiplexer stage that emits at least one data transmission control signal as a function of a set data protocol;
• and
• a reception block having a predeterminable number of data input channels on a bus side thereof, a predeterminable number of data output channels on a processor side thereof, and means for transposing data from the input channels to the output channels, which means includes a reception multiplexer stage that emits at least one data transmission control signal as a function of the data protocol.
