APPARATUS AND METHOD FOR CONTROLLING ENGINE OF VEHICLE HAVING CVVL

摘要

Disclosed is an engine control method and apparatus for vehicles having a vehicle lift variable control system. According to the engine control method and apparatus for vehicles having a vehicle lift variable control system of the present invention, precise controls for engine's ignition timing and fuel amounts is possible, and hence there is an advantage to further improve reliability for products, as calibration values to calibrate engine fuel amounts and ignition timing are derived based on learned values for the vehicle lift deviation derived on the basis of learned values for fuel amount deviations per cylinder and learned values for fuel amount [Reference numerals] (101) Cooling water temperature reaches prescribed value after engine driving;(103) Execute cylinder balancing learning;(105) Derive learning value for air intake deviations per cylinder;(107) Derive learning value for valve lift deviation;(109) Derive calibration value;(111) Calibrate fuel amount and ignition timing with calibration value;(113) Drive engine;(AA) START;(BB) END
