Inside ventilation technique for vehicle

摘要

Disclosed is an inside ventilation system of a vehicle for a driver or an occupant to achieve a more comfortable inside environment in the summer or winter. The inside ventilation system includes a control unit configured to receive an operating signal from a smart key, sense an inside temperature of the vehicle when the operating signal is transferred and judging whether the inside temperature is deviated from a required temperature range; a comparison process of comparing the inside temperature and a battery temperature when the inside temperature is deviated from the required temperature range; and a control process of controlling a heating, ventilation, and air conditioning system (HVAC) and an operation of a battery operated fan by comparing the inside temperature and the battery temperature.

主权项

1. An inside ventilation method of a vehicle, comprising:
receiving, by a control unit, an operating signal from a smart key; sensing, by one or more temperature sensor, an inside temperature of the vehicle once the operating signal is transmitted to the control unit determining, by the control unit, whether the inside temperature deviates from a required temperature range; comparing, by the control unit, the inside temperature and a battery temperature when the inside temperature deviates from the required temperature range; controlling, by the control unit, a heating, ventilation, and air conditioning system (HVAC) and operation of a battery operated fan based upon the comparison of the inside temperature and the battery temperature; determining, by the control unit, whether the inside temperature of the vehicle is less than 20° C. when the inside temperature deviates from the required temperature; wherein when the control unit determines that the inside temperature is less than 20° C., the heater of the HVAC and the battery operated fan are controlled based on the comparison of the inside temperature and the battery temperature; and determining, by the control unit, whether the battery temperature is less than 0° C. when the inside temperature is less than the battery temperature, wherein when the control unit determines that the battery temperature is less than 0° C., the heater of the HVAC is turned on and the battery operated fan is turned off.
