Abstract

The invention provides an apparatus for controlling a water pump of a hybrid vehicle and a method thereof. The apparatus includes: a thermostat configured to determine a circulation direction of a coolant according to a temperature of the coolant that is exhausted from an engine, a motorized water pump mounted between the engine and the thermostat for circulating the coolant, a first coolant temperature sensor configured to detect the temperature of the coolant flowing from the engine to a cooler, a second coolant temperature sensor configured to detect a temperature of the coolant flowing from the cooler to the engine, and a control portion that applies a temperature difference detected by the first and second coolant temperature sensors and a coolant flux to calculate a heat emission amount of the engine, and thus drive the motorized water pump according to the heat emission amount.

Description

technical field [0001] The invention relates to a water pump control device of a hybrid electric vehicle. More particularly, the present invention relates to a water pump control device for controlling a motorized water pump according to heat dissipation of an engine and a control method thereof. Background technique [0002] Hybrid vehicles have been developed and mass-produced in such a way as to meet emission regulations and improve fuel efficiency. [0003] There are various types of hybrid vehicles, and when an engine and an electric motor are generally used as power sources, there are an EV (Electric Vehicle) driven only by an electric motor and an HEV (Hybrid Electric Vehicle) driven by an engine and an electric motor. [0004] In a hybrid vehicle, coolant is forcibly circulated to prevent engine overheating, coolant passages are respectively formed in a cylinder block and a cylinder head of the engine, and a water pump circulates coolant through the coolant passages...
