The invention discloses an electric back door control method capable of intelligently adapting to in-vehicle air pressure change, which comprises the following steps of: when an electric back door is opened, sending a closing instruction to a controller; the controller reads the vehicle sealing state and the air conditioner blower speed grade; selecting a plurality of pre-calibrated speed modes to close the electric back door, and enabling the closing time of the electric back door under all working conditions to be within the target interval; if an obstacle is detected in the closing process of the electric back door, the obstacle is fed back to the controller, and then the driving mechanism drives the electric back door to be opened to the maximum position; and if the obstacle is not detected, the driving mechanism drives the electric back door to be closed to the primary locking position, and the back door lock is locked. According to the method, the driving speeds of various driving mechanisms are calibrated and stored in advance to adapt to changes of different working conditions, and the proper driving speed is selected according to the actual working conditions, so that the running time of the electric back door is in a standard interval under any working condition, and the fluctuation of the closing time of the electric back door is reduced.

    本发明公开了一种智能适应车内气压变化电动背门控制方法,在电动背门开启的状态下,发送关闭指令给控制器;控制器读取车辆密封状态和空调鼓风机速度等级;选择预先标定的多种速度模式关闭电动背门,使所有工况下的电动背门关闭时间都在目标区间内;电动背门关闭过程中如果检查到障碍物,则反馈给控制器,随后驱动机构带动电动背门开启到最大位置;如果未检查到障碍物,则驱动机构带动电动背门关闭到一级锁紧位置,背门锁锁紧。本发明事先标定存储多种驱动机构的驱动速度来适应不同工况的变化,并根据实际的工况选择合适的驱动速度,从而使得在任何工况下,电动背门的运行时间均处于标准区间,因此减小了电动背门关闭时间的波动。
