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.
