Abstract: PURPOSE: An ignition control method of an engine for a vehicle is provided to improve accelerative performance during travelling by minimizing lag of ignition time and to improve gradability. CONSTITUTION: In an ignition control method of an engine for a vehicle, ECU(Electronic Control Unit) decides whether the current engine RPM(Revolutions Per Minute) is within the predetermined range(S110) and decides whether the current vehicle speed is over the reference value(S120). The ECU decides whether the current coolant temperature is within the predetermined range(S130). The ECU decides whether the current gear stage is shifted into 1-stage to 3-stage(S140). The ECU decides whether the current opening degree of a throttle is under the reference value or over the reference value(S160,S170). If the opening degree is under the reference value, the anti-jerk function is applied and ignition system is controlled by reducing lag according to the RPM(S180). If the opening degree is over the reference value, the anti-jerk function is not applied(S190) and lag control of the ignition system is not performed on a rough road.
