HEATING SYSTEM OF HYBRID VEHICLE AND METHOD FOR CONTROLLING THE SAME

摘要

A heating system may include a cooling water line connected to a vehicle engine, a heat exchanger provided at the cooling line, the heat exchanger being arranged within an air conditioning duct, thermoelectric elements each attached, and a controller for controlling start or stop of the engine, to maintain a temperature of the cooling water between an upper limit temperature and a lower limit temperature.

主权项

1. A heating system of a hybrid vehicle comprising:
a cooling water line connected to an engine of the vehicle; at least one heat exchanger provided at the cooling line such that cooling water flows through the heat exchanger, the heat exchanger being arranged within an air conditioning duct, through which air flows; at least one thermoelectric element each attached, at a first surface thereof, to the heat exchanger while being exposed, at a second surface thereof, to air flowing through the air conditioning duct such that the second surface functions as a heating surface; and a controller for controlling start or stop of the engine, to maintain a temperature of the cooling water between an upper limit temperature and a lower limit temperature while controlling operation of the at least one thermoelectric element such that a temperature measured at an outlet of the air conditioning duct satisfies a target temperature.
