ELECTROMOTIVE WATER PUMP CONTROL SYSTEM AND A METHOD FOR A HYBRID VEHICLE CAPABLE OF SATISFYING HEATING DEMAND OF A DRIVER BY CONSIDERING POWER OF A WATER PUMP FOR THE INDOOR HEATING OF A VEHICLE AND COOLING OF AN ENGINE

摘要

PURPOSE: An electromotive water pump control system for hybrid vehicles is provided to improve the fuel efficiency because the electromotive water pump operates by considering the indoor heating of the vehicle and cooling of an engine.;CONSTITUTION: An electromotive water pump control system for a hybrid vehicle comprises an ECU(Engine control unit) (11), a FATC(Full Automatic Temperature Controler) (12) and a HCU(Hybrid Control Unit)(13). The ECU calculates the operating RPM(Revolution Per Minute) of a water pump and power for cooling the engine and indoor heating of the vehicle. The HCU operates the electromotive water pump with a maximum value of the operating power of the water pump from the ECU and a full automatic temperature controller for the indoor heating of the vehicle and cooling the engine.;COPYRIGHT KIPO 2012
