The invention discloses a sealing strip, a sealing assembly and a method for solving vehicle sealing squeal abnormal sound. The sealing strip comprises a sealing strip bubble pipe part and a sealing strip connecting part which are connected with each other. A sealed cavity is formed in the sealing strip bubble pipe part, and the sealing strip bubble pipe part is provided with an air tap for inflating and deflating the sealed cavity. The sealing assembly comprises an air pump, a controller and a sealing strip; the air pump is connected with the air tap through a pipeline; and the controller is in signal connection with the air pump to control the air pump to inflate and deflate the sealed cavity in the sealing strip bubble pipe part. The method comprises the following steps that s1, the offset of a vehicle door at different vehicle speeds is obtained, and the interference amount needing to be increased by a sealing strip at different vehicle speeds is determined through the offset; s2, the controller obtains a vehicle speed signal; and s3, the controller controls the air pump to inflate or deflate the sealed cavity in the bubble pipe part of the sealing strip according to the vehicle speed value so as to adjust the interference amount of the sealing strip. The interference amount of the sealing strip can be dynamically adjusted under different high-speed working conditions, and the problem that the high-speed wind noise of a vehicle is poor is solved.

    本发明公开了一种解决车辆密封啸叫异响的密封条、密封组件和方法,密封条包括相互连接的密封条泡管部和密封条连接部;密封条泡管部内设有密闭腔体,密封条泡管部设有使密闭腔体充气和放气的气嘴。密封组件包括气泵、控制器和密封条;气泵通过管路与气嘴连接;控制器与气泵信号连接以控制气泵对密封条泡管部内的密闭腔体充气和抽气。方法包括以下步骤:s1.获取不同车速下车门的偏移量,通过偏移量确定出不同车速下密封条所需增加的干涉量;s2.控制器获取车速信号;s3.控制器根据车速值控制气泵向密封条泡管部内的密闭腔体充气或抽气,以调整密封条的干涉量。本发明能够在不同高速工况下,对密封条的干涉量进行动态调整,改善车辆高速风噪差的问题。
