In addition, the matching of the driver's and passenger's seat warmer systems can be improved, thereby reducing quality problems.

Hereinafter, a seat warmer control system for a vehicle according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a seat warmer system for an automobile according to an exemplary embodiment of the present invention.

An automobile seat warmer system according to an embodiment of the present invention is largely provided with a temperature sensing unit 152 and a heating unit 154 inside the switching control module 100 and the seat cushion 150 of the driver's seat and the passenger seat, respectively.

First, the switching control module 100 includes a switch unit 140, a singular display unit 120, a relay unit 130, and a microcomputer 110.

The switch unit 140 generates a singular signal each time a passenger presses a button, and the singular is changed every time the button is pressed. In other words, press once to make 3 steps, press twice to make 2 steps, press 3 times to make 1 press, and press 4 times to turn off. For reference, in the present embodiment has been described with an example of 0 to 3 stages, this may be changed according to the manufacturer's control specifications.

The singular display unit 120 is connected to the microcomputer 110 to display the number of stages selected by the occupant according to the control signal of the microcomputer 110, and includes a lighting device (not shown) therein and corresponds to the currently selected stage lighting device. Turn on to improve visibility.

The relay unit 130 is connected to the heating unit 154, respectively, and simultaneously supplies power to the heating unit 154 provided in the seat cushion 150 of the driver's seat and the passenger seat according to a control signal input from the microcomputer 110. Or optionally supply and shut off.

The microcomputer 110 controls the overall seat warmer system for the vehicle according to the exemplary embodiment of the present invention.

The microcomputer 110 selectively controls the relay unit 130 according to the singular signal input each time the occupant presses the switch unit 140 to the heating unit 154 corresponding to the input switch unit 140. Supply power. In addition, the lighting device of the singular display unit 120 corresponding to the singular signal input from the switch unit 140 is turned on to display the currently selected singular number.

In addition, by receiving the temperature of the seat cushion 150 from the temperature sensing unit 152, the relay unit 130 is controlled to maintain the seat cushion 150 in the temperature range set in the currently selected stage to the heating unit 154 Supply and disconnect power.

The heating unit 154 is installed inside the seat cushion 150 of the driver's seat and the passenger seat, respectively, and heats the seat cushion 150 when power is supplied from the relay unit 130.

The temperature sensing unit 152 is installed inside the seat cushion 150 of the driver's seat and the passenger seat, respectively, and senses a temperature of the seat cushion 150 and transmits the temperature to the microcomputer 110.

An operation process of the seat warmer system for a vehicle according to the exemplary embodiment of the present invention configured as described above will be described in detail.

In the operation process of the seat warmer system for the vehicle, when the first passenger presses the switch unit 140 corresponding to the seat cushion 150 of the driver's seat or the passenger seat for a predetermined number of times, a singular signal is generated whenever the switch unit 140 is pressed. It is input to the microcomputer 110.

When the singular signal is input from the switch unit 140, the microcomputer 110 controls the relay unit 130 to supply power to the heating unit 154 installed in the seat cushion 150. Accordingly, the heating unit 154 generates heat by the applied power to heat the seat cushion 150.
