ABSTRACT:
An ignition control system for controlling an ignition timing of an internal combustion engine when the CPU is failed or the engine is started, includes a charging and discharging circuit in which a predetermined crank angle range is converted into a voltage to be charged in which the charged voltage is discharged so as to form a charge and discharge voltage wave, a charge and discharge voltage wave comparison circuit for comparing the charge and discharge voltage wave with a battery voltage wave, and a back-up circuit for control the ignition timing in accordance with the signal from the charge and discharge voltage wave comparison circuit.
