A heating seat apparatus for a vehicle is provided to sense weight of occupants and to transfer heat to seats uniformly by controlling temperature of the seats according to temperature distributions measured in a pressure sensing mat. A heating seat apparatus for a vehicle comprises a pressure sensing mat(20), and first and second heat wire layers(30,40). The pressure sensing mat is installed with a plurality of pressure sensors at a lower part of a seat cushion(10). The first heat wire layer is arranged with heat wires in one direction. The second heat wire layer is arranged with heat wires perpendicular to the heat wires of the first heat wire layer. The temperature of each area on the seat is controlled uniformly according to the measured temperature distributions of the pressure sensing mat. Sensors of the pressure sensing mat are connected with microcontrollers. The microcontrollers are connected with a heat wire controller. The heat wire controller is connected with first and second layer current control units. |
