Abstract

PURPOSE:To make it possible to carry out comfortable heating by an electrically heated seat, simultaneously with heating by an automatic air-conditioning system, by changing current fed through a heating resistor element in the electrically heated seat in accordance with signals for controlling the rotational speed of a blower fan motor in the automatic air-conditioning system. CONSTITUTION:When a heater switch 10 is selectively set at an AUTO position, a relay contact 18 is closed. Further, when the control of heating by an air-conditioning control unit 12 is initiated, a large drive current is fed to a blower fan motor 14 to carry out fast heating since the deviation between the temperature of the passenger's compartment and a first desired temperature is large. A control signal at this time is also fed to a heater controlling power transistor 20 so that fast heating is carried out by heat from heaters 4, 5 in the electrically heated seat 1. The deviation from the desired value decreases, the rotational speed of the blower fan motor is steppedly lowered, the current of the heaters 4, 5 is simultaneously lowered.

The signal wire is connected so as to energize the relay contact 18a and close the relay contact 18a, and the signal wire is connected so that current flows through the heater portions 4a and 5a of the heaters 4 and 5 when the switch is switched to the H1 position.

急速暖房が行なわれる。　。First, when the AUTO position of the heater switch 10 is selected, current flows through the relay 18 to close the relay contact 18a, and the base of the power transistor 20 for controlling the heater is connected to the output of the air conditioning control unit 12. In this state, when the heating control by the air conditioning control unit 12 was started, I was surprised! Since the temperature deviation of the cabin temperature with respect to the wind and rain H1 is large, the air-conditioning control unit 12 transmits the wind m control signal that gives the wind and rain H1 to the parts transistor. 16, a large drive current flows through the proa fan motor 14, increasing the amount of air blown out and performing rapid heating. Konotosa no J! The + signal for river control 11 is also supplied to the power transistor 20 for heater control via the relay contact 18a, and the heaters 4 and 5 built into the seat 1 also control the air volume H.
1, rapid heating is performed by the flow of tc lightning current and heating of the heaters 4 and 5. .

暖房に自動的に切換えられる。Subsequently, when the temperature deviation with respect to the target humidity decreases, the wind m control signal from the air conditioning control unit 12 is switched to a signal corresponding to the winds ff1M0 and lo.
The rotation speed of the proa fan motor 14 is lowered in stages,
At the same time, the current of the heaters 4 and 5 is reduced by the power transistor 20, and rapid heating is automatically switched to normal heating that suits the passenger's preference.

When switching to i or 0 position, relay 18
Since the drive current is cut off and the relay contact 18a hears, the Jfil from the air conditioning controller 1-roll unit 12
Heating operation of the electric heating sheet can be performed by operating a switch independent of the ffl control signal.

よる快適な暖房状態を得ることができる。<Effects of the Invention> As explained above, according to the present invention, the current flowing through the heating resistor provided in the seat is controlled to control the rotational speed of the blower nozzle of the vehicle air conditioner. Since the interlocking control is performed by the operation of the control element based on the signal, the heater switch is switched to the interlocking position such as A jJ T O.
3, the current control of the electric heating seam 1- is performed in conjunction with the air volume control of the differential motor in the heating mode of the air conditioner, and the air vA is controlled without performing a dedicated heating operation for the electric heating seam 1-. A comfortable heating state can be obtained by heating the electric heating sheet 1 at the same time as heating by the device 6.
