Abstract

An electric water pump control apparatus actively controls an electric water pump in a high speed range or a high load condition as a vehicle accelerates or overtakes. An electric water pump control method may include determining whether an engine is in a high speed/high load condition or in a normal condition by detecting an engine speed, fuel consumption amount, and coolant temperature, determining whether the coolant temperature is less than a predetermined second temperature, if the engine is in a high speed/high load condition, calculating a speed of the electric water pump by applying fuel consumption amount and engine speed, if the coolant temperature is less than a second temperature and determining a final speed of the electric water pump by applying a compensation coefficient according to the coolant temperature, and operating the electric water pump with the final speed to circulate the coolant.
