Vehicle heater control system {HEATER CONTROL SYSTEM FOR VEHICLE}

The present invention relates to a vehicle heater control system, and more particularly, to a vehicle heater control system capable of controlling a heater unit in response to whether or not an occupant is in a vehicle.

In general, vehicle heating is performed using engine heat. That is, the cooling water that absorbs engine heat passes through the heater core installed in the air conditioner, the air passes through the heater core, heats the air through heat exchange with the cooling water, and supplies the heated air to the room to perform heating. do.

However, in the case of a heating method using engine heat, heating is not performed because the temperature of the cooling water is low before the engine is heated to a sufficient temperature. That is, there was an inconvenience that heating was not performed at the initial stage of engine operation. In addition, since it is a method of supplying warm air, it is not possible to perform local heating exclusively for each occupant.

In addition, in the case of an electric vehicle without an engine, the above method of heating cannot be fundamentally implemented.

Therefore, a radiant heater capable of generating heat using electricity, discharging generated heat into a vehicle interior in the form of radiant heat, and performing local heating has been installed. A radiant heat heater installed in a vehicle is often referred to as a panel heater because it is mainly in the shape of a thin flat plate.

Conventional radiant heat heaters have insufficient heating performance on cold days because they cannot change the heating required according to the initial state of the body or the outside air temperature in keeping the body warm at a certain distance.

In addition, radiant heat heaters have problems in that heating comfort is deteriorated due to excessive heating on days when it is not very cold, or unnecessary energy consumption occurs.

The present invention has been devised to solve the above problems, and an object of the present invention is to provide a vehicle heater control system capable of controlling a heater unit in response to whether or not an occupant is in a vehicle.
