ABSTRACT:
In an ignition controller for an internal combustion engine, an angle sensor includes a plurality of sensor means for individually outputting a pulse signal SGT1 corresponding to a first reference crank angle and a pulse signal SGT2 corresponding to a second reference crank angle and a control/arithmetic operation circuit includes a timing calculation means for calculating the timings at which ignition coils are controlled according to an operating state, count means for counting the number of the pulses of one of respective pulse signals which are detected between two continuous pulses of the other of them, reverse rotation discriminating means for discriminating the reverse rotation of the internal combustion engine based on the count values CA1 and CA2 of the respective pulse signals and control prohibition means for prohibiting the output of drive signals P1 and P2 in response to a reverse rotation discriminating signal to thereby prohibit ignition control in the occurrence of the reverse rotation by discriminating the reverse rotation from the pulse counting state of respective reference crank angles having a different phase each other. With this arrangement, there is provided the ignition controller for the internal combustion engine capable of avoiding erroneous control caused by the reverse rotation.
