The purpose of the present invention is to minimize peak power in a vehicle seat provided with a plurality of heaters. This vehicle seat, which is provided with a seat cushion and a seat back, is provided with: a first heater for heating first regions in the seat cushion and the seat back; a second heater for heating second regions in the seat cushion and the seat back which are different to the first regions; and a control device to which the first heater and the second heater are connected. The control device is capable of executing pulse width modulation (PWM) control in which the current supplied to the first heater and the second heater is controlled by setting the energization periods per unit time Tu. When the first heater and the second heater are energized, a first energization period Ts1, which is the energization period of the first heater in the unit time Tu, and a second energization period Ts2, which is the energization period of the second heater in the unit time Tu, arestaggered in the PWM control.

    目的在于抑制具有加热器的交通工具用座椅的峰值功率。交通工具用座椅由座椅坐垫和座椅靠背组成。座椅坐垫及座椅靠背包括第1加热器,用于对所述座椅坐垫或所述座椅靠背中的第1区域进行加热;第2加热器,用于对所述座椅坐垫及所述座椅靠背中,与第1区域不同的第2区域进行加热;控制装置,与所述第1加热器及所述第2加热器连接。所述控制装置,能够设定的单位时间Tu内的通电期间,对所述第1加热器及所述第2加热器中的电流进行PWM控制,控制所述第1加热器及所述第2加热器通电时,将所述第1通电期间Ts1与所述第2通电期间Ts2相互错开进行PWM控制。
