The device provides for the control of operations which depend on running parameters and which are repetitive in combustion motor machines, particularly ignition and/or injection and/or gear control operations. Control signals are generated in a computer (11), which are function of the output signals provided by a sensor (10) connected to a rotary shaft as well as by other sensors sensitive to running parameters, in order to start off the operations to be controlled through at least a final control stage (13, 14). At least one auxiliary control device (17, 18) is associated with the computer (11) and the output signals of this device are provided through a switching device (12), to the final control stages (13, 14) alternatly with the output signals of the computer (11). The switching device (12) which is preferably comprised of a multiplexor, is controlled by an error decoding stage (19) by means of which the series or parallel signals of the computer are decoded in order to control the correct operation of the latter. |
