The invention provides an AMT automatic gearbox gear shifting control method and system.The method comprises the steps that after gear shifting needs to be conducted on an AMT automatic gearbox and a clutch completes meshing, the corrected stable throttle valve opening degree of a throttle valve is adopted as the required opening degree to control the throttle valve, the throttle valve opening degree continues for a first preset time, and the air inflow of an engine is increased; the recovery rate and the transient dynamic property of engine power can be improved; the driving experience and the safety of the vehicle are improved; in addition, hardware is not changed, only software strategies need to be upgraded, and the development and application cost is low. The device is well suitable for the working conditions such as vehicle rapid acceleration and climbing which urgently need power, and the application value is high.

    本发明提供一种AMT自动变速箱换档控制方法和系统,该方法包括:在AMT自动变速箱需要进行换挡,且离合器完成啮合后,先采用节气门修正后的稳定节气门开度作为需求开度控制节气门,且持续第一预设时间,增大发动机的进气量,能够提高发动机动力的恢复速率和瞬态动力性;提高驾驶体验和车辆的安全性;另外,不改动硬件,只需升级软件策略,开发及应用成本低。很好的适用于车辆急加速、爬坡等急需动力的工况,应用价值高。
