Abstract

The present invention relates to a water pump control apparatus of a hybrid vehicle and a control method thereof. An exemplary apparatus according to the present invention includes a thermostat determining a circulation path of the coolant, a coolant temperature sensor, a motorized water pump configured to pump a coolant, and a control portion for controlling the motorized water pump to circulate the coolant, if the hybrid vehicle enters into an EV mode or an idle engine stop mode if the coolant temperature exceeds a predetermined temperature. An exemplary method of the present invention includes the steps of suspending operation of the motorized water pump if the coolant temperature is less than a predetermined value until a cooling fan is operated, and controlling a driving speed of the motorized water pump according to a load of the cooling fan in operation.

Description

technical field [0001] The invention relates to a motorized water pump for a vehicle, especially a hybrid vehicle. Background technique [0002] Hybrid vehicles have been developed and increasingly mass-produced to be sold and driven by users. Different kinds of hybrid vehicles exist today. A typical hybrid usually includes an engine and an electric motor. When the hybrid is in electric vehicle mode (EV mode), only the electric motor works. Optionally, when the hybrid vehicle is in hybrid vehicle mode (HV mode), both the electric motor and the engine are operating. [0003] Hybrid vehicles usually generate electricity through regenerative braking to charge the battery, and reduce fuel consumption and exhaust gas through the ISG (Idle Stop and Start) system. Hybrids forcibly circulate coolant to keep the engine from overheating. Therefore, if the hybrid vehicle enters the EV mode or the ISG mode when the coolant temperature is high, the water pump operated by the engine ...
