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.

    本发明公开了一种座椅气动腰托充气控制方法,包括:设置状态位用于描述腰托气袋是否处在排空状态,第一状态位表示腰托气袋非空,第二状态位表示腰托气袋处在排空状态,状态位在断电情况下能够保留数据;初始状态,将腰托气袋状态位设于第一状态位;若执行排空动作,则腰托气袋状态位修改为第二状态位;每次上电启动后,读取腰托气袋状态位;若为第二状态位则执行设计动作,若为第一状态位执行排气动作并将腰托气袋状态位设于第二状态位后执行设计动作。本发明摒弃现有技术采用的OPV方案,能避免发生过压风险和气道上气体泄露风险,并且能降低生产成本。
