S42, adjusting the seat to a preset rated temperature according to the current body temperature;
in the step, when the current body temperature is higher than the preset rated maximum temperature, the seat is cooled through the preset ventilation equipment so as to be adjusted to the preset rated temperature; when the current body temperature is within a preset temperature range, the seat is enabled to keep the current state; and when the current body temperature is lower than the preset rated minimum temperature, heating the seat through preset heating equipment so as to adjust the seat to the preset rated temperature.
And S43, adjusting the inflation and deflation states of the air bags in the seat according to the current body pressure and the current adjustment mode of the seat.
In this step, the step of adjusting the inflation/deflation state of the air bag in the seat comprises:
