Specifically, when the corresponding relationship is a mapping relationship, different motion characteristic parameters are mapped with different preset air pressure ranges, and the preset air pressure range corresponding to the current motion characteristic parameter can be determined as the target air pressure range based on the mapping relationship. When the corresponding relation is a calculation relation, the motion characteristic parameters can be represented by the representation values, different motion characteristic parameters correspond to different representation values, a quantitative relation between the representation values and critical values (maximum values and/or minimum values) of the target air pressure range can be pre-established, based on the quantitative relation, the representation values corresponding to the current motion characteristic parameters are determined, the current representation values are substituted into the quantitative relation, the critical values of the target air pressure range can be calculated, and the corresponding air pressure range is determined to be the target air pressure range based on the critical values.

The method determines the corresponding air pressure adjusting parameter to control the operation of the air pressure adjuster of the sealing strip based on the action characteristic parameter of the vehicle door where the sealing strip is located and the current air pressure of the sealing strip, and based on the method, the air pressure in the sealing strip of the vehicle door is not fixed but can be adjusted according to the air pressure required by the actual action of the vehicle door, so that the air pressure of the sealing strip in the actual use process of the vehicle can reach the air pressure required by the actual application scene, the performance of the sealing strip in the use process of the vehicle door can be effectively improved, and the user experience in the use process of the vehicle door can be improved.
Further, in this embodiment, when the current air pressure is outside the target air pressure range and the current air pressure is greater than the maximum air pressure value of the target air pressure range, it is determined that the air pressure adjustment parameter includes a reduced air pressure; or, when the current air pressure is outside the target air pressure range and the current air pressure is less than the minimum air pressure value of the target air pressure range, determining that the air pressure adjustment parameter comprises increasing air pressure.
When the target air pressure range is a numerical value range with a maximum air pressure value and a minimum air pressure value, when the current air pressure is larger than the maximum air pressure value of the target air pressure range, the air pressure adjusting parameter comprises reduced air pressure, when the current air pressure is smaller than the minimum air pressure value of the target air pressure range, the air pressure adjusting parameter comprises increased air pressure, and when the current air pressure is larger than or equal to the minimum air pressure value and smaller than or equal to the maximum air pressure value, the current air pressure of the sealing strip is kept unchanged.
When the target air pressure range is a numerical value range smaller than or equal to the maximum air pressure value, when the current air pressure is larger than the maximum air pressure value, the air pressure adjusting parameter comprises reduced air pressure, and when the current air pressure is smaller than or equal to the maximum air pressure value, the current air pressure of the sealing strip is kept unchanged.
When the target air pressure range is a numerical value range which is larger than or equal to the minimum air pressure value, when the current air pressure is smaller than the minimum air pressure value, the air pressure adjusting parameter comprises the increased air pressure, and when the current air pressure is larger than or equal to the minimum air pressure value, the current air pressure of the sealing strip is kept unchanged.
Based on this, when current atmospheric pressure exceedes the target atmospheric pressure scope, confirm the atmospheric pressure direction of adjusting through the magnitude relation of current atmospheric pressure and the critical value of target atmospheric pressure scope, be favorable to current atmospheric pressure can approach the target atmospheric pressure scope of current door action demand.
Further, in order to improve the accuracy of the air pressure regulation of the sealing strip and ensure that the air pressure in the sealing strip can quickly and accurately reach a target air pressure range, when the current air pressure is greater than the maximum air pressure value, a first deviation amount between the current air pressure and the maximum air pressure value can be determined, the air pressure regulation amplitude or the air pressure regulation speed is determined according to the first deviation amount, and the air pressure regulation parameters comprise reduced air pressure and the air pressure regulation amplitude or the air pressure regulation speed; when the current air pressure is smaller than the minimum air pressure value, a second deviation amount of the current air pressure and the minimum air pressure value can be further determined, the air pressure adjusting amplitude or the air pressure adjusting speed is determined according to the second deviation amount, and the air pressure adjusting parameters comprise the increased air pressure and the air pressure adjusting amplitude or the air pressure adjusting speed.
