System and method for controlling ignition of internal combustion engine for vehicle
First Claim
1. An ignition control system for an internal combustion engine for a vehicle comprising:
- gear position discriminating means for discriminating the gear position of a gear transmission for transmitting the output power of the internal combustion engine to a driving shaft of the vehicle;
ignition-characteristics setting means for setting the ignition characteristics of the internal combustion engine optimum for each of the gear positions depending upon the gear position discriminated by said gear position discriminating means;
engine speed detecting means for detecting the engine speed of the internal combustion engine;
ignition position determining means for determining the ignition position at the engine speed detected by said engine speed detecting means depending upon the ignition characteristics set by said ignition-characteristics setting means; and
ignition trigger signal feed means for supplying a trigger signal to an ignition device for the internal combustion engine at the ignition position determined by said ignition position determining means.

Abstract
An ignition control system and an ignition control method for an internal combustion engine for a vehicle which are capable of permitting the internal combustion engine to exhibit ideal ignition characteristics optimum for each of gear positions of a gear transmission of the engine. The ignition characteristics of the internal combustion engine optimum for each of the gear positions are set depending upon the gear position discriminated by a gear position discriminator, to thereby determine the ignition position according to the so-set ignition characteristics. Such construction permits the ignition characteristics to be changed over depending upon the gear position, thus, the ignition of the engine may be carried out constantly at the optimum ignition position.
