Abstract

PURPOSE:To enable breaking current to be corrected with simple constitution in a controller provided with a current detecting means for detecting the amount of ignition coil current by constituting said means to generate a binary signal showing whether or not the amount of coil current exceeds a predetermined value. CONSTITUTION:CPU 5 generates the ignition timing controlling signal on the basis of output signals of a crank angle sensor or the like. By supplying these signals to the input of D type FF 8 is supplied the ignition controlling signal of FF 8 to a power transistor 9. Thus, the primary current of an ignition coil 10 is supplied and shut off to generate high voltage across the secondary side coil. Also, then, the coil current is detected by a current detecting circuit 40 to change the current supply starting period of coil current on the basis of result of said detection. In such device said circuit 40 is constituted to generate the binary signal showing whether or not the amount of coil current exceeds a predetermined value, and when it exceeds the predetermined value, the current supply time is corrected to be elongated.
