PURPOSE:To make it possible to feed sufficient ignition energy even upon high speed running, by independently arranging a gate circuit for distributing an output signal from an ignition timing computing circuit and another gate circuit for distributing an output signal from an energizing angle control circuit. CONSTITUTION:Output signals from first and second angular position detectors 1, 2 for detecting the rotational angular position of an internal-combustion engine, are delivered to and timedly composed in series, in a gate circuit 3 which delivers an output signal to an ignition timing computing circuit 4 and an energizing angle control circuit 5. Further, there is provided an FF6 which is set by the output signal of the circuit 2 but reset by the output signal of the device 1. Furthermore, there are provided second through fifth gate circuits 7 through 10 which deliver a logic AND of the output signal of the computing circuit 4 and the output signals (m, n) of the FF6, and another logic AND of the output signal of the control circuit 5 and the output signals (m, n) of the FF6. By obtaining a logic OR of the outputs of the gate circuits 7, 9, 8, 10, ignition coils 15, 16 are controlled. |
