Abstract: A method for preventing engine stall in applying idle load of an automatic transmission vehicle is provided to restrain engine stall even under power steering full-turn operation, by turning off a compressor of an air conditioner for the predetermined time if the total mileage of the vehicle is within reference distance. A method for preventing engine stall in applying idle load of an automatic transmission vehicle comprises the steps of: judging whether the cumulated mileage of the vehicle is within pre-set reference distance and full load conditions are satisfied or not according to the present injection amount of fuel; judging a stop/low-speed state that present engine RPM(Revolution Per Minute) is in an idle RPM region, a transmission gear is in a D-stage input state, and the present vehicle speed is below reference speed, if all conditions are satisfied; and forcibly turning off a compressor of an air conditioner for the predetermined time, if a switch of the air conditioner is turned on after the state that all conditions are satisfied is continued for the set time.

Abstract: A control method of a VGT is provided to prevent the damage of a VGT at low speed and to maintain the power performance of a vehicle at high speed by setting up the target base boost pressure low at low speed and setting up the target boost pressure separately at high speed. A control method of a VGT(variable geometry turbocharger) comprises the steps of having two or more target base boost maps and setting up the assigned target base boost map according to the gear position assigned to an ECU, and setting up the target base boost pressure of the target base boost map for low speed to be relatively lower than the target base boost pressure of the target base boost map for high speed.
