Seat pneumatic waist support inflation control method, storage medium and controller

Abstract

The invention discloses an inflation control method for a pneumatic waist support of a seat, which comprises the following steps: setting a state position for describing whether a waist support air bag is in an emptying state or not, a first state position indicating that the waist support air bag is not empty, a second state position indicating that the waist support air bag is in the emptying state, and the state positions can retain data under the condition of power failure; in the initial state, the waist support air bag state position is set to be the first state position; if the emptying action is executed, the state position of the waist support air bag is modified into a second state position; after each time of power-on starting, the state position of the waist support air bag is read; if the state position is the second state position, the design action is executed, and if the state position is the first state position, the exhaust action is executed, and the design action is executed after the waist support air bag state position is set to the second state position. An OPV scheme adopted in the prior art is abandoned, the overpressure risk and the gas leakage risk on the gas channel can be avoided, and the production cost can be reduced.
