A method of controlling changeover between modes of operation of an internal combustion engine, particularly between full engine operation and half engine operation, having several control devices (18.1,18.2, figure 1) able to exchange data with one another by a data connection comprises a step 101 in which it is checked whether changeover of mode of operation is to take place and, if changeover is to take place, a step 102-106 in which testing of the data connection between the control devices (18.1,18.2, figure 1) is carried out and/or a step 107-109 in which an equalisation of the operational state of the control devices (18.1,18.2, figure 1) is carried out. The step of checking may comprise evaluating the state or content of data evaluation means, which may be a datagram of a data bus or the state of the register. The test of the data connection may comprise checking the transmission of at least one data packet for errors or, in the case that the controllers (18.1,18.2, figure 1) are electrically connected, testing the electrical connection. The checking may be delayed until after an equalization time, or at predetermined times or in response to predetermined events. |
