Abstract
A current on the primary side of an ignition coil is subjected to repeated conduction/cutoff control in accordance with an ignition control signal of an ECU to thereby generate a high voltage for ignition twice or more in one combustion stroke. In such a multiple ignition system for an internal combustion engine, the primary current of the ignition coil is detected by a resistor to thereby make the ECU recognize the fact that the primary current has reached a value not smaller than a set value through a signal line when the primary current becomes not smaller than the set value. The ECU determines cutoff timing in the second-time et seq. in the repeated conduction/cutoff control on the basis of the recognition.
