PURPOSE: A creep force control method is provided to prevent vehicle accidents and improve driver's convenience in driving. CONSTITUTION: A creep force control method comprises steps of deciding the shift range is D-range when a driver stops a running vehicle with a brake(S100,S110); deciding the opening degree of a throttle valve is lower than the predetermined reference value if the gear level is set up into a first stage(S120); deciding a throttle is an idle state and deciding a brake switch by operation of the brake is on(140); if rpm of the engine is greater than the predetermined reference value, with vehicle speed of 0Kph and oil temperature is below the predetermined reference value, deciding the predetermined reference time has passed in the condition; deciding creep flag, the determined variable for creep control, is 1; deciding the brake switch is off, the rpm of the engine is below the predetermined reference value, or the opening degree of the throttle vale is greater than the predetermined reference value; and outputting a duty control signal to control creep force and setting up the creep flag into 1 and then returning main routine, if the creep flag is zero(S200). Thus, vehicle accidents are prevented and driver's convenience is increased.
