Abstract
An engine control method for preventing an engine of a vehicle from stalling on a sloped road includes steps of: detecting whether a shifting lever is in a neutral stage (N-stage); measuring a vehicle speed and a slope angle of the sloped road, and calculating a load acting on a vehicle body on the sloped road; accelerating an engine a first time to increase an engine RPM so that an engine torque is larger than the load; and accelerating the engine a second time to move the vehicle when the shifting lever enters into a driving gear stage (D-stage).
