Method for engine control based on control timing prediction and vehicle thereof

A vehicle comprising:

• an engine control unit configured to:
• perform a start angle operation time prediction control under an entire driving range of the vehicle,
• calculate a crank tooth corresponding to an operation time of fuel injection and of ignition by converting into a number of teeth corresponding to the operation time,
• calculate a tooth period average value that is divided into a current tooth period average value and a past tooth period average value through a number of teeth read in a reverse direction from the latest calculation time,
• calculate a tooth period variation from the tooth period average value,
• calculate a future tooth period average value that matches the tooth period of the operation time from the tooth period average value and the tooth period variation by multiplying the current tooth period average value by a tooth period group variation,
• calculate a start angle corresponding to the operation time of the fuel injection and ignition by subtracting a predicted angle corresponding to the operation time from an end angle of the fuel injection and ignition,
• perform driver sync confirmation and sync task performing with a crank signal and a cam signal of the engine,
• calculate the end angle and the operation time at a time of the sync task performing, and
• confirm the end angle and the operation time through the start angle operation time prediction control,
• wherein the engine control unit comprises:
• an engine position management driver, an injector application, an ignition application, an injector driver, and an igniter driver,
• wherein the injector driver and the igniter driver read a tooth period of a current time from the engine position management driver, and calculate a start angle of fuel injection and ignition in a future tooth period to match an actual operation time based on a tooth period change tendency of a calculation time, and
• wherein the tooth period of the calculation time is calculated using an end angle and the operation time of the fuel injection and ignition, and the end angle and the operation time are calculated by performing engine start information calculation control.
