Abstract:
To suppress peak power in a vehicle seat including a plurality of heaters.SOLUTION: A vehicle seat includes: a seat cushion; and a seat back. The vehicle seat further includes: a first heater for heating a first region of the seat cushion and the seat back; a second heater for heating a second region different from the first region of the seat cushion and the seat back; a control section to which the first heater and the second heater are connected. The control section sets an energization period per unit time Tu, thereby enabling execution of PWM control for controlling currents to be supplied to the first heater and the second heater. When energizing to the first heater and the second heater, a first energization period Ts1 to be an energization period to the first heater in the unit time Tu and a second energization period Ts2 to be an energization period to the second heater in the unit time Tu are shifted in the PWM control.SELECTED DRAWING: Figure 5
