Ignition control system
First Claim
1. An ignition control system for controlling an ignition of an engine, comprising:
- reference voltage generating means for generating a reference voltage each time an output signal is produced; and
ignition controller means for controlling ignition of the engine based on the reference voltage and the output signal, the ignition controller means including;
voltage determining means for comparing the reference voltage signal with the output signal, and outputting a comparison result signal, andcontrol means for outputting an ignition signal to an ignition coil on the basis of the comparison result signal and a pulse signal.

Abstract
An ignition control system controls an ignition of a vehicle engine based on a pulse signal generated by a pulse coil in response to a rotation of the vehicle engine by using a rectified output of a regulator for correcting a generated output of an AC-generator activated by the vehicle engine. The ignition control system does not require a dedicated AC generator and modifications of an engine layout. It includes an anti-theft feature and is applicable to vehicles that do not use a battery. The ignition control system includes a reference voltage generator that generates a reference voltage each time a rectified output is produced by a generator, and an ignition controller that controls ignition of the vehicle engine on the basis of the reference voltage and the rectified output. The ignition controller includes a voltage determining device that determines whether the rectified output is equal to or larger than a predetermined voltage, compares a reference voltage signal with the rectified output and outputs a signal indicative of a determination result. The ignition controller also includes a control device that outputs an ignition signal to an ignition coil on the basis of the comparison result signal and a pulse signal.
