<p>PURPOSE:To automatically restore the runaway of computer, by using a periodic signal used in the computer and a signal produced when the computer normally executes processing, and resetting the signal outputted from the computer when the relation between both the signals is in disorder. CONSTITUTION:A revolving signal 211 corresponding to a periodic signal A and a reference position signal 241 produced from a rotating sensor 13 are fed to an internal-combustion engine control computer 11, and an ignition signal 221 corresponding to output signal B of the computer 11 and an internal-combustion engine control signal 25 are output. Further, the signal 211 from the sensor 13 is fed to an automatic reset circuit 12, and the ignition signal 221 from the computer 11 is fed to an igniter 14 and the reset circuit 12. Further, the reset circuit 12 checks the relation between the ignition signal 221 and the signal 211, and when the relation is in disorder, the runaway of the computer 11 is judged, and the output of the ignition signal 221 and the control signal 25 is reset by giving the reset signal 23 to the computer 11, to automatically restore the runaway.</p> |
