Deflate the left airbag to adjust the center of gravity of the body and achieve a smooth turning transition. When the commercial vehicle turns to the right, it is opposite to the operation of the left air spring. When the commercial vehicle is running on a smooth road, the internal pressure of the air spring changes little, so no adjustment is required. Therefore, when the commercial vehicle turns, the internal pressure of the air spring is charged and deflated according to the change of the internal pressure of the air spring to achieve active anti-rollover.
